LOCATION

In selecting the location, the aesthetic andfunctional use of the appliance are primaryconcerns. However, vent system routing to theexterior and access to the fuel supply are alsoimportant. Consideration should be given totraffic ways, furniture, draperies, etc., due toelevated surface temperatures (Figure 2 ). Thelocation should also be free of electrical, plumb-ing or other heating/air conditioning ducting.

This direct vent appliance is uniquely suited forinstallations requiring a utility shelf positioneddirectly above the fireplace. Utility shelves likethese are commonly used for locating televi-sion sets and decorative plants.

To provide for the lowest possible shelf surfaceuse the alternate rear vent outlet with attachedventing routed in a way to minimize obstruc-tions to the use of the space above the appli-ance. Do not insulate the space between theappliance and the area above it. See Figure 3.The minimum height from the base of theappliance to the underside of combustible ma-terials used to construct a utility shelf in thisfashion is shown in the table in Figure 3.

APPLIANCE AND VENT CLEARANCES

The appliance is approved with zero clearance tocombustible materials on all sides (as detailed inTable 2 ), with the following exception: When theunit is installed with one side flush with a wall, thewall on the other side of the unit must not extendbeyond the front edge of the unit. In addition,when the unit is recessed, the side walls sur-rounding the unit must not extend beyond thefront edge of the unit. See Figure 2.

Typical Locations

The appliance should be mounted on a fullysupported base extending the full width anddepth of the unit. The appliance may be locatedon or near conventional construction materi-als. However, if installed on combustible mate-rials, such as carpeting, vinyl tile, etc., a metalor wood barrier covering the entire bottomsurface must be used.

These instructions should be used as a guide-line and do not supersede local codes in anyway. Install vent according to local codes,these instructions, the current National FuelGas Code (ANSI-Z223.1) in the USA or thecurrent standards of CAN/CGA-B149.1 and -B149.2 in Canada.

These fireplaces are designed, testedand listed for operation and installationwith, and only with, Secure Vent™ (SV4.5) Direct Vent System Components,manufactured by Security Chimneys In-ternational, or FireCraft's Secure Flex™Flexible Vent Components. These ap-proved vent system components are la-beled for identification. DO NOT use anyother manufacturer's vent componentswith these appliances. These fireplacesmust be vented directly to the outside.

The vent system may not service multipleappliances, and must never be connected to aflue serving a solid fuel burning appliance. Thevent pipe is tested to be run inside an enclos-ing wall (such as a chase). There is no require-ment for inspection openings in the enclosingwall at any of the joints in the vent pipe.

Preparing the Appliance Vent Collar onCombined Top and Rear Vent Models

Each of the unit's two vent collars are sealedwith a cover plate, and a seal plate and gasket.The cover, and seal plate and gasket must beremoved from the vent collar being used. Referto Figure 12 for top vent usage and Figure 13for rear, and the following steps to prepare theappropriate collar for use.

From the vent collar being used, remove the fourscrews securing the vent seal plate and gasket.Remove and discard the seal plate and gasket.When the top vent collar is being used, frominside the firebox, remove the four cover platesecuring screws. Remove and discard the coverplate. Reinstall and securely tighten all four coverplate screws.

When the rear vent collar is being used, frominside the firebox, remove the 2 screws securingthe lintel to the rear wall of the firebox, thenremove the lintel. Remove the four cover platesecuring screws. Remove and discard the coverplate. Reinstall and securely tighten all four coverplate screws. Re-secure the lintel to the rear wallof the firebox.

Installation of Vent Restrictor

Install a vent restrictor (provided) in the appli-ance top flue outlet as shown in Figure 14 orrear flue outlet as shown in Figure 15. It is heldin place by friction, only.

Select Venting System - Horizontal or Vertical

With the appliance secured in framing, deter-mine vent routing and identify the exteriortermination location. The following sectionsdescribe vertical (roof) and horizontal (exteriorwall) vent applications. Refer to the sectionrelating to your installation. A list of approvedventing components is shown in the threetables starting on page 24.

VERTICAL TERMINATION SYSTEMS (ROOF)

Figure 16, and Figures 28 through 32 onpage 13 and 14 and their associatedVertical Vent Tables illustrate the variousvertical venting configurations that are pos-sible for use with these appliances. SecureVent pipe applications are shown in thesefigures; Secure Flex pipe may also be used.A Vertical Vent Table summarizes eachsystem’s minimum and maximum verticaland horizontal length values that can beused to design and install the vent compo-nents in a variety of applications.

Both these vertical vent systems terminatethrough the roof. The minimum vent heightabove the roof and/or adjacent walls is speci-fied in ANSI Z223.1-(latest edition) (In Canada,the current CAN-1 B149 installation code) bymajor building codes. Always consult yourlocal codes for specific requirements. A gen-eral guide to follow is the Gas Vent Rule (referto Figure 4 on page 5).

Vertical (Straight) Installation

Determine the number of straight vent sectionsrequired. 4 ¹⁄₂" (114 mm), 10 ¹⁄₂" (267 mm), 22¹⁄₂" (572 mm), 34 ¹⁄₂" (876 mm) and 46 ¹⁄₂"(1181 mm) net section lengths are available.Plan the vent lengths so that a joint does notoccur at the intersection of ceiling or roofjoists. Refer to the Vent Section Length Chart.

Vertical (Offset) Installation

Analyze the vent routing and determine the quan-tities of vent sections and number of elbowsrequired. Refer to Vertical Vent Figures andTables on page 13 and 14 to select the type ofvertical installation desired. Vent sections are avail-able in net lengths of 4 ¹⁄₂" (114 mm), 10 ¹⁄₂" (267mm), 22 ¹⁄₂" (572 mm), 34 ¹⁄₂" (876 mm) and 46 ¹⁄₂"(1181 mm). Refer to the Vent Section LengthChart on page 10 for an aid in selecting lengthcombinations. Elbows are available in 90° and 45°configurations. Refer to Figure 23 for the SV4.5E45and SV4.5E90 elbow dimensional specifications.Where required, a telescopic vent section(SV4.5LA) may be used to provide the installerwith an option in installing in tight and confinedspaces or where the vent run made up of fixedlength pieces develops a joint in a undesirablelocation, or will not build up to the required length.The SV4.5LA Telescopic Vent Section has aneffective length of from 1 ¹⁄₂" (38 mm) to 7 ¹⁄₂" (191mm). The SV4.5LA is fitted with a locking inclinedchannel end (identical to a normal vent sectioncomponent) and a plain end with 3 pilot holes. Slipthe plain end over the locking channel end of astandard SV4.5 vent component the requireddistance and secure with three screws.

Maintain a minimum 1" (25 mm) clearance tocombustible materials for all vertical elements.Clearances for all horizontal elements are 3"(76 mm) on top, 1" (25 mm) on sides and 1"(25 mm) on the bottom.

A. Frame ceiling opening - Use a plumb linefrom the ceiling above the appliance to locatecenter of the vertical run. Cut and/or frame anopening, 10¹⁄₂" x 10¹⁄₂" (267mm x 267mm) insidedimensions, about this center mark (Figure 17).

To attach a vent component to the appliancecollar, align the dimpled end over the collar,adjusting the radial alignment until the fourlocking dimples are aligned with the inlet of thefour inclined channels on the collar (refer toFigure 18 ). Push the vent component againstthe collar until it fully engages, then twist thecomponent clockwise, running the dimplesdown and along the incline channels until theyseat at the end of the channels. The unitizeddesign of the Secure Vent components willengage and seal both the inner and outer pipeelements with the same procedure. Sealant andsecuring screws are not required.

Note: An elbow may also be attached to theappliance collar. Attach in the same manner asyou would a vent section.

C. Attach vent components to each other - Othervent sections may be added to the previouslyinstalled section in accordance with the require-ments of the vertical vent figures and tables. Toadd another vent component to a length of ventrun, align the dimpled end over the inclinedchannel end of the previously installed section,adjusting the radial alignment until the four lock-ing dimples are aligned with the inlets of the fourincline channels of the previous section. Pushthe vent component against the previous sectionuntil it fully engages, then twist the componentclockwise running the dimples down and alongthe incline channels until they seat at the end ofthe channels. This seating position is indicatedby the alignment of the arrow and dimple asshown in Figure 19.

B. Attach vent components to appliance - Se-cure Vent SV4.5 direct vent system componentsare unitized concentric pipe components featur-ing positive twist lock connections (see Figure18 ). All of the appliances covered in thisdocument are fitted with collars having lockinginclined channels. The dimpled end of the ventcomponents fit over the appliance collar to cre-ate the positive twist lock connection.

D2. Install firestop thimble at the ceiling to rooflocation - Position appropriate firestop thimble(see thimble table on page 24) at the bottom sideof ceiling and secure temporarily with two appro-priate fasteners. Attach permanently, using atleast two more fasteners, after vent sections havebeen assembled through the firestop thimble andafter any necessary adjustments have been made.

Ensure the thimble penetrates the roof open-ing. The thimble must extend completelythrough the ceiling or roof cavity to the outer-most plane of the roof. Use thimble extensionSVTE26 when the distance between the outsideof the roof and the inside of the ceiling exceedsthe height of the firestop thimble. The thimbleprovides for zero clearances to combustiblesand must be used at the ceiling/roof in manu-factured homes with Secure Vent double wallvent sections. Maintain 1 in. (25.4 mm) clear-ance between the thimble and the outer pipeof the secure vent chimney system. See Fig-ure 20 for pitched roofs or flat roofs with flatceilings or Figure 21 for pitched roofs withcathedral ceilings.

D1. Install firestop/spacer at ceiling betweenstories - Install a firestop/spacer (catalog no.96K87 - Secure Vent; catalog no.19M41 - SecureFlex) at the bottom side of the ceiling to the ceilingjoists. Route the vent sections through the framedopening and secure the firestop/spacer with ap-propriate fasteners at each corner.

Remember to maintain 1" (25 mm) clearancebetween vertical chimney sections and com-bustibles, framing members, and attic orceiling insulation.

K. Install the vertical termination - The finalstep involves installation of the SV4.5VTR Verti-cal Termination. Extend the vent sections to theheight as shown in the "Vertical vent terminationsection" on page 5. The SV4.5VTR VerticalTermination (Figure 27 ) installs in the exactsame fashion as any other Secure Vent section.Align the termination over the end of the previ-ously installed section, adjusting the radial align-ment until the four locking dimples of the termi-nation are aligned with the inlets of the fourincline channels of the last vent section. Pushthe termination down until it fully engages, thentwist the termination clockwise running thedimples down and along the incline channelsuntil they seat at the end of the channels.

I. Install the roof flashing - Extend the ventsections through the roof structure. Install theroof flashing over the vent section and positionsuch that the vent column rises vertically (usecarpenters level) (Figure 25 ). Secure along pe-rimeter to secure flashing or adjust roofing tooverlap the flashing edges at top and sides onlyand trim where necessary. Seal the top and bothsides of the flashing with waterproof caulking.

J. Install the storm collar - Install the stormcollar, supplied with the flashing, over thevent/flashing joint. See Figure 26. Loosen thestorm collar screw. Slide collar down until itmeets the top of the flashing. Tighten theadjusting screw. Apply non-combustible caulk-ing or mastic around the circumference of thejoint to provide a water tight seal.

E. Support the vertical vent run sections -Support the vertical portion of the venting sys-tem every 8 feet (2.4m) above the fireplace ventoutlet using field provided support straps (con-ventional plumber's tape). Secure the plumber'stape to the framing members with nails orscrews. Loop the tape around the vent, secur-ing the ends of the tape to the framing. The tapemust not be secured directly with a fastenerinto the vent pipe. See Figure 22.

F. Change vent direction to horizontal/in-clined run - At transition from or to a horizon-tal/inclined run, install the SV4.5E45 andSV4.5E90 elbows in the same manner as thestraight vent sections. The elbows feature atwist section to allow them to be routed aboutthe center axis of their initial collar section toalign with the required direction of the nextvent run element. Twist elbow sections in aclockwise direction only so as to avoid thepossiblity of unlocking any of the previouslyconnected vent sections. See Figure 23.

If the vent system extends more than 5' (1.5 m)above the roof flashing, stabilizers may benecessary. Additional screws may be used atsection joints for added stability. Guy wiresmay be attached to the joint for additionalsupport on multiple joint configurations.

G. Continue installation of horizontal/inclinedsections - Continue with the installation of thestraight vent sections in horizontal/inclined runas described in Step C. Install support strapsevery 5' (1.52 m) along horizontal/inclined ventruns using conventional plumber’s tape. It isvery important that the horizontal/inclinedrun be maintained in a straight (no dips) andslightly elevated plane in a direction awayfrom the fireplace ¹⁄₄" per foot (20 mm permeter) of horizontal vent. Use a carpenter’slevel to measure from a constant surface andadjust the support straps as necessary.

It is important to maintain the required clear-ances to combustibles: 1" (25 mm) at allsides for all vertical runs; and 3" (76 mm) atthe top, 1" (25 mm) at sides, and 1" (25 mm)at the bottom for all horizontal/inclined runs.

H. Frame roof opening - Identify location forvent at the roof. Cut and/or frame opening perRoof Framing Chart and Figure 24.

Figure 33

Figure 33, and Figures 37 to 44 on pages 17,18 and 19 and their associated Horizontal VentTable illustrate the various horizontal ventingconfigurations that are possible for use withthese appliances. Secure Vent pipe applica-tions are shown in these figures; Secure Flexpipe may also be used. A Horizontal Vent Tablesummarizes each system’s minimum and maxi-mum vertical and horizontal length values thatcan be used to design and install the ventcomponents in a variety of applications.

Both of these horizontal vent systems terminatethrough an outside wall. Building Codes limit orprohibit terminating in specific areas. Refer toFigure 7 on page 6 for location guidelines.

Secure Vent SV4.5 direct vent system compo-nents are unitized concentric pipe componentsfeaturing positive twist lock connection, (refer toFigure 18 on page 11). All of the appliancescovered in this document are fitted with collarshaving locking inclined channels. The dimpledend of the vent components fit over the appliancecollar to create the positive twist lock connection.

A. Plan the vent run -Analyze the vent routing and determine thetypes and quantities of sections required4 ¹⁄₂" (114 mm), 10 ¹⁄₂" (267 mm), 22 ¹⁄₂" (572mm), 34 ¹⁄₂" (876 mm) and 46 ¹⁄₂" (1181 mm)net section lengths are available. Plan the ventlengths so that a joint does not occur at theintersection of ceiling or roof joists. Make al-lowances for elbows as indicated in Figure 21.

Maintain a minimum 1" (25 mm) clearance tocombustibles on the vertical sections. Clear-ances for the horizontal runs are; 3" (76 mm)on top, 1" (25 mm) on sides, and 1" (25 mm)at the bottom.

B. Frame exterior wall opening -Locate the center of the vent outlet on theexterior wall according to the dimensions shownin Figure 8 on page 7. Cut and/or frame anopening, 10 ¹⁄₂" X 12 ¹⁄₈" (267 mm x 308mm)inside dimensions, about this center.

C. Frame ceiling opening - If the verticalroute is to penetrate a ceiling, use plumb lineto locate the center above the appliance. Cutand/or frame an opening, 10 ¹⁄₂" x 10 ¹⁄₂" (267mm x 267 mm) inside dimensions, about thiscenter (refer to Figure 17 on page 11 ).

D. Attach vent components to appliance - Toattach a vent component to the appliance collar,align the dimpled end over the collar, adjusting theradial alignment until the four locking dimples arealigned with the inlets of the four incline channelson the collar (refer to Figure 18 on page 11).

G. Support the vertical run sections -On the vertical run, support the venting systemevery 8 feet (2.4m) above the fireplace ventoutlet with field provided support straps(Plumber's tape). Attach the straps to the ventpipe and secure to the framing members withnails or screws. See Figure 22 on page 12.

H. Change vent direction - At transition fromor to a horizontal/inclined run, install theSV4.5E45 and SV4.5E90 elbows in the samemanner as the straight vent sections. Theelbows feature a twist section to allow them tobe routed about the center axis of their initialcollar section to align with the required direc-tion of the next vent run element. Twist elbowsections in a clockwise direction only so as toavoid the possiblity of unlocking any of thepreviously connected vent sections. See Fig-ure 23 on page 12.

I. Continue installation of horizontal/inclinedsections - Continue with the installation of thestraight vent sections in horizontal/inclined runas described in Step E. Install support strapsevery 5 ft. (1.52 m) along horizontal/inclinedvent runs using conventional plumber’s tape.See Figure 33. It is very important that thehorizontal/inclined run be maintained in astraight (no dips) and slightly elevated planein a direction away from the fireplace of ¹⁄₄"rise per foot (20 mm per meter) of horizontalvent. Use a carpenter’s level to measure from aconstant surface and adjust the support strapsas necessary.

It is important to maintain the required clear-ances to combustibles: 1" (25 mm) at all sidesfor all vertical runs; and 3" (76 mm) at the top,1" (25 mm) at sides, and 1" (25 mm) at thebottom for all horizontal/inclined runs

HORIZONTAL (OUTSIDE WALL)TERMINATION SYSTEM

Push the vent component against the collar until itfully engages, then twist the component clockwise,running the dimples down and along the inclinechannels until they seat at the end of the channels.The unitized design of the Secure Vent compo-nents will engage and seal both the inner and outerpipe elements with the same procedure. Sealantand securing screws are not required.

Note: An elbow may also be attached to theappliance collar. Attach in the same manner asyou would a vent section.

E. Attach vent components to each other -Other vent sections may be added to the previ-ously installed section in accordance with therequirements of the vent tables. To add anothervent component to a length of vent run, align thedimpled end of the component over the inclinedchannel end of the previously installed section,adjusting the radial alignment until the fourlocking dimples are aligned with the inlets of thefour incline channels of the previous section.Push the vent component against the previoussection until it fully engages, then twist thecomponent clockwise running the dimples downand along the incline channels until they seat atthe end of the channels. This seating position isindicated by the alignment of the arrow anddimple as shown in Figure 19 on page 11.

F. Install firestop/spacer at ceiling betweenstories - Install a firestop/spacer (catalog no.96K87 - Secure Vent; catalog no.19M41 - SecureFlex) at the bottom side of the ceiling to the ceilingjoists. Route the vent sections through the framedopening and secure the firestop/spacer with ap-propriate fasteners at each corner.

Remember to maintain 1" (25 mm) clearancebetween vertical chimney sections and com-bustibles, framing members, and attic orceiling insulation.

K. Assemble vent run to exterior wall - If notpreviously measured, locate the center of thevent at the exterior wall. Prepare an opening asdescribed in Step B. Assemble the vent systemto point where the terminus of the last section iswithin 5 in. (127 mm) to 9¹⁄₄ in. (235 mm)inboard of the exterior surface to which thetermination is to be attached, see Figure 35. Ifthe terminus of the last section is not within thisdistance, use the telescopic vent sectionSV4.5LA, as the last vent section. For wallthicknesses greater than that shown in Figure35, refer to table 3 on page 17. This table liststhe additional venting components needed (inaddition to the termination and adapter) for aparticular range of wall thicknesses.

L. Attach termination adapter - Attach theadapter (adapter - SV4.5RCH - provided withthe termination) to the vent section or telescop-ing vent section), elbow or appliance collar asshown in Figure 34 in the same manner as anySV4.5 vent component (refer to Step E).

M. Install Firestop/Spacer at exterior wall -When using either of the square terminations,install a Firestop/Spacer (SV4.5HF) over theopening at the exterior side of the framing, longside up, with the 3 inch spacer clearance at thetop as shown in Figure 34, and nail into place.(The Firestop/Spacer may also be installed overthe opening at the interior side of the framing.)When using the round termination, a separatefirestop/spacer is not required since this termi-nation has integral spacers which provide thesame function as a separate firestop/spacer.

1. Install the square termination (SV4.5HTS) or(SV4.5HTSS)- For the last step , from outside theexterior wall, slide the collars of the termination ontothe adapter (the outer over the outer and the innerinside the inner) until the termination seats againstthe exterior wall surface to which it will be attached.Orient the housing of the termination with the arrowpointed upwards. Secure the termination to theexterior wall. The horizontal termination must notbe recessed into the exterior wall or siding by morethan the 1 ¹⁄₄" (32 mm) as shown in Figure 35.

2. Install the round termination (SV4.5HTR)– See Figure 36 for an illustration of the roundtermination. For the last step , from outside theexterior wall, slide the collars of the terminationonto the adapter (the outer over the outer andthe inner inside the inner) until the terminationseats against the exterior wall surface to whichit will be attached. Orient the housing of thetermination with the arrow pointed upwards.Secure the termination to the exterior wall.

N. Install the desired termination -See the horizontal venting figures for appli-cation restrictions on the round termination(SV4.5HTR).

Installing the Square Horizontal Termination (SV4.5HTS),Small Square Horizontal Termination (SV4.5HTSS)

or Round Horizontal Termination (SV4.5HTR).

The SV4.5HTR Round Termination may not beused when the appliance is vented directly outthe wall from the rear. Do Not recess theSV4.5HTR round termination at all.

VERTICAL OR HORIZONTAL VENTING USINGSECURE FLEX KITS AND COMPONENTS

Secure Flex venting kits and components maybe used in any venting application where rigidSecure Vent (SV4.5) direct vent componentscan be used. All restrictions, clearances andallowances that pertain to the rigid piping applyto the flexible venting. Secure Flex kits may notbe modified; also, under no circumstancesmay separate sections of flex pipe be joinedtogether. Secure Flex kits may be added to theend of a vent run made up of rigid Secure Vent(SV4.5) vent sections provided that doing sodoes not violate any of the venting length,height, routing, horizontal to vertical ratio re-quirements or clearance considerations de-tailed in this manual.

Secure Flex kits come with an included adapterthat can be fitted to the appliance collar or theinclined channel end of the last Secure Vent(SV4.5) vent section in a rigid system in theexact same fashion as any other Secure Ventsection. Align the dimpled end of the adapterover the previously installed section or appli-ance collar, adjusting the radial alignment untilthe four locking dimples of the adapter arealigned with the inlets of the four incline chan-nels of the last vent section or collar. Push onthe adapter until it fully engages, then twist theadapter clockwise running the dimples downand along the incline channels until they seat atthe end of the channels.

Attach the flexible vent to the adapter asfollows (see also Figure 45):

A. Install the Inner Flex Pipe -

1. Install the small gear clamp loosely aroundthe inner flexible vent pipe, push it back outof the way.

2. Apply a bead of Mill-Pac Black (700°F)high temperature sealant - Catalog No.10K81) to the inner adapter collar, approxi-mately ¹⁄₂ inch from the end.

3. Pull and extend the inner flexible vent pipe.4. Slide the inner flex pipe over the adapter

collar. Ensure the flexible vent pipe com-pletely engages the adapter collar to a dis-tance of 1³⁄₄ inches from the end, and that itis free from damage or tears.

5. Slide the gear clamp down and tighten it fullyto secure the flexible vent to the adapter innercollar approximately ³⁄₄ inch from the end ofthe flex.

6. Install three screws 120 degrees apartthrough the flexible vent pipe and into theadapter collar just below the gear clamp toprovide additional security to the connection.

B. Install the Outer Flex Pipe -

1. Install the large gear clamp loosely aroundthe outer flexible vent pipe, push it back outof the way.

2. Apply a bead of Mill-Pac Black (700°F) hightemperature sealant - Catalog No. 10K81)to the outer adapter collar; to the grooves ofthe collar which extend approximately 1 inchfrom the end and to the flat surface, approxi-mately 1³⁄₈ inches from the end.

3. Pull and extend the outer flexible vent pipe.4. Slide the outer flex pipe over the adapter

collar. Ensure the flexible vent pipe com-pletely engages the adapter collar to a dis-tance of 1³⁄₄ inches from the end, and that itis free from damage or tears.

5. Slide the gear clamp down and tighten it fullyto secure the flexible vent to the adapter outercollar approximately ³⁄₄ inch from the end ofthe flex.

6. Install three screws 120 degrees apartthrough the flexible vent pipe and into theadapter collar just below the gear clamp toprovide additional security to the connection.

C. Route Flex Vent -

Ensure that the flex vent is properly routed toprovide the required clearance. Do Not allowthe flexible vent to bend in a radius tighter than5" (127 mm). Refer to Figure 46. Supporthorizontal sections of flex with metal straps at2 foot (0.61 m) intervals.

Step 5. BLOWER WIRING (Figure 48)

The blower and blower ON/Off control switchare factory installed. An electrical outlet box isalso factory installed for the connection of theelectrical power supply to the blower.

1. Route a 3-wire, 120Vac 60Hz 1ph power lineto the lower right rear corner of the appliance.

2. Connect the black supply wire to the topoutlet's black pigtail lead and to the switch'sblack lead. Connect the white supply wire to theneutral terminal of the outlet box. See Figure 48.It is not necessary to remove the outlet box.

3. Connect the ground supply wire to the outletbox green ground screw as shown.

4. Plug the blower cord into the bottom recep-tacle of the outlet box.

Step 6. CONNECTING GAS LINE ANDCHECKING GAS TYPE

Make gas line connections -

Figure 49 on page 22 illustrates two methodsfor connecting the gas supply. The flex-linemethod is acceptable in the U.S., however,Canadian requirements vary depending on lo-cality. Installation must be in compliance withlocal codes. All codes require that a shut-offvalve be mounted in the supply line. Both amanual shut off valve and flex line are providedwith the fireplace. The flex line is rated for bothnatural and propane gas.

The gas control valve is located in the lowercontrol compartment. To access the valve,open the lower control compartment dooras shown in Figure 50 on page 22. Themi l l ivo l t contro l va lve has a ³ ⁄ ₈ "(10 mm) NPT thread inlet port.

Secure all joints tightly using appropriatetools and sealing compounds (ensure pro-pane resistant compounds are used in pro-pane applications).

Check gas type -

The appliance is factory set to operate on natu-ral gas. See the conversion procedure shownon page 26 if propane gas is to be used.

IMPORTANT: Ground lead must be con-nected to the green screw located on theoutlet box. See Figure 48. Failure to do sowill result in a potential safety hazard.The appliance must be electricallygrounded in accordance with local codesor, in the absence of local codes, theNational Electrical Code, ANSI/NFPA 70-(latest edition). (In Canada, the currentCSA C22-1 Canadian Electrical Code.)

Note: Secure Flex vent must be attached toSecure Flex terminations only. DO NOTsubstitute Secure Vent terminations or theSecure Vent adapter for Secure Flex compo-nents. The collars of Secure Flex termina-tions and adapters have a different circum-ference than that used with the Secure Ventpipe. Additionally, Secure Flex componentshave an extended length center tube for usein attaching the flexible vent.

Step 4. MILLIVOLT CIRCUIT WIRING(Figure 47 )

The gas valve is set in place and pre-wired atthe factory.

1. Select any of the following optional con-trols: appliance-mounted (rocker switch) orwall-mounted switch, thermostat, or one ofthe optional remote control kits. If appliance-mounted ON/OFF control is selected mount itin the gas valve mounting bracket.

2. If wall-mounted ON/OFF control or thermo-stat is selected mount it in a convenient loca-tion on a wall near the fireplace.

3. Wire the control switch within the millivoltcontrol circuit using the 15 feet of 2 conductorwire supplied with the unit.

Caution: Do not connect the optional wallswitch to a 120V power supply.

4. Alternatively, the appliance may be oper-ated without the use of the controls indicatedin step 1, solely by manipulating the gas valvecontrol knob. In order to use this method,twist the free ends of the two conductor wire(located on top of the unit) together as shownin Figure 47.

Note: The supplied 15 feet of 2 conductor wirehas one end of each conductor connected tothe gas valve circuit and the other end of eachconductor placed loose inside the bottom con-trol compartment.

INSTALLING THE GLASS DOOR

Step 8. CHECKING APPLIANCE OPERATION

With gas line installed run initial system check-out before closing up the front of the unit.Follow the pilot lighting instructions pro-vided in the Homeowner's Care and Opera-tion Instructions. For piezo ignitor locationsee Figure 51 (millivolt appliances only).

Note: Instructions are also found on the pullout panel located next to the gas valve.

When first lighting the appliance, it will take a fewminutes for the line to purge itself of air. Oncepurging is complete, the pilot and burner will lightand operate as indicated in the instruction manual.Subsequent lightings of the appliance will notrequire such purging. Inspect the pilot flame(remove logs, if necessary, handling carefully).

Step 9. INSTALLING THE GLASS DOOR

Retrieve the glass door. Visually inspect thegasket on the backside of the frame. Gasketsurface must be clean, free of irregularities andseated firmly.

Position the door in front of the firebox openingwith the bottom of the door held away from thefireplace (Figure 54). Hook the top flange of thedoor frame over the top of the firebox frame.Let the bottom of the door frame swing gentlyin towards the fireplace ensuring that the gas-ket seats evenly as the door frame draws shut.Fasten the two latches located underneath thefirebox floor to the door's vee-flange. Closeboth the latches securely.

Replace logs if removed for pilot inspection.

To light the burner; turn “ON” the remote wallswitch and rotate the gas valve control knobcounterclockwise to the “ON” position (“ON” willbe at the bottom side of the valve).

SIT and Honeywell Millivolt Appliance Checkout

The pilot flame should be steady, not lifting orfloating. Flame should be blue in color withtraces of orange at the outer edge.The top ³⁄₈" (10 mm) at the pilot generator(thermopile) and the top ¹⁄₈" min (tip) of the quickdrop out thermocouple should be engulfed in thepilot flame.

Step 11. HOOD INSTALLATION

All of these appliances must have hoods in-stalled prior to operating.On all clean face units, slide the hood into theslots on the lower edge of the radiant panel(Figure 56 on page 24).On louvered face units, slide the hood into theslots on the lower edge of the cabinet top(Figure 57 on page 24 ).

To adjust the flame, move the adjustment rod(located in the lower control area) up or down toincrease or reduce the air shutter opening, re-spectively. Position the air shutter to the factorysetting (Figure 55). Allow the burner to operatefor at least 15 minutes. Observe the flame con-tinuously. If it appears weak or sooty as previ-ously described, adjust the air shutter by pushingor pulling on the adjustment rod until the flameappearance is as desired.

The adjustment rod and associated adjustableair shutter is patented technology. Flame adjust-ments can be made quickly and accurately totaste without the need of disassembling theappliance and waiting for 30 minutes after eachadjustment.

FINISHING REQUIREMENTS

Wall Details

Complete finished interior wall. To install theappliance facing flush with the finished wall,position framework to accommodate the thick-ness of the finished wall (Figures 56 and 57 onpage 24).

Note: Combustible wall finish materials and/or surround materials must not be allowed toencroach the area defined by the appliancefront face (black sheet metal). Never allowcombustible materials to be positioned infront of or overlapping the appliance frontface. See Figures 56 and 57 on page 24.

Step 10. BURNER ADJUSTMENTS

Flame Appearance and sooting

Proper flame appearance is a matter of taste.Generally, most people prefer the warm glow ofa yellow to orange flame. Appliances operatedwith air shutter openings that are too large willexhibit flames that are blue and transparent.These weak, blue and transparent flames aretermed anemic. If the air shutter opening is toosmall sooting may develop.

Sooting is indicated by black puffs developingat the tips of very long orange flames. Sootingresults in black deposits forming on the logs,appliance inside surfaces and on exterior sur-faces adjacent to the vent termination. Sootingis caused by incomplete combustion in theflames and lack of combustion air entering theair shutter opening. To achieve a warm yellowto orange flame with an orange body that doesnot soot, the shutter opening must be adjustedbetween these two extremes.

No smoke or soot should be present. Reposi-tion the logs if flames impinge on any of them.

If the logs are properly positioned and sootingconditions exist, the air shutter opening on themain burner tube should be adjusted. Normally,the more offsets in the vent system, the greaterthe need for the air shutter to be opened further.

Burner Adjustment

CAUTION: THE ADJUSTMENT ROD ANDNEARBY APPLIANCE SURFACES ARE HOT.EXERCISE CAUTION TO AVOID INJURY WHILEADJUSTING FLAME APPEARANCE.

WARNING: AIR SHUTTER ADJUSTMENTSHOULD ONLY BE PERFORMED BY AQUALIFIED PROFESSIONAL SERVICETECHNICIAN.

IMPORTANT: ENSURE THAT THE FRONTGLASS PANEL IS IN PLACE AND SEALEDDURING ADJUSTMENT.

Non-combustible materials, such as surroundsand other appliance trim, may be installed onthe appliance front face with these exceptions:they must not cover any portion of the glassor louvers; they must not cover any portionof the top radiant panel and the air gapssurrounding the top radiant panel.

Note: If the flame still appears anemic with theair shutter closed all the way against the stop(usually a result of lengthy vertical runs), turnthe appliance off, turn the gas supply off, waitfor the parts to cool, remove the glass door andlogs to access the air shutter. The shutter isprevented from actually closing all the way byan adjustment set screw (see Figure 55). Re-move this screw using a ¹⁄₄ inch nut driver.Reinstall the logs and glass door, turn the gasback on and then restart the appliance. After 30minutes, reobserve the flame. Adjust the airshutter as previously described.

When satisfied that the appliance operatesproperly, proceed to finish the installation.Leave the control knob in the ON position andthe remote switch OFF. Close the lower controlcompartment door.

WARNING: NEVER OPERATE THE APPLI-ANCE WITHOUT THE FRONT GLASS EN-CLOSURE PANEL IN PLACE AND SECURE.

WARNING: HANDLE THIS GLASS WITHEXTREME CARE! THE GLASS PANEL ISSUSCEPTIBLE TO DAMAGE — DO NOTSCRATCH WHILE HANDLING OR WHILERE-INSTALLING THE GLASS DOORFRAME.
