PRIMARY INTEGRAL COMPONENTS - ACCESSORY OPTIONSUL LISTED ELECTRIC DUCT HEATERS
Pictures shown are representative only and may vary with requirements and availability.________________________________________________________________________________________________________
MAGNETIC CONTACTOR
Disconnecting magnetic contactors (Option B6) are so arranged as to break allungrounded lines. Disconnecting contactors, both magnetic or mercury type,that break all ungrounded lines are required on all UL listed duct heaters.
The number and amperage of the contactors will vary depending upon the KWand voltage.________________________________________________________________________________________________________
MERCURY CONTACTORDisconnecting Mercury contactors (Option B3/B6) are usually used where silent operation and/or frequent cycling is desired. The design of the contactor virtually eliminates contact noise and provides for long expectant life under heavy use. Mercury contactors can only be installed in the vertical position.
___________________________________________________________________________________________________
AIRFLOW SWITCHThe airflow (pressure) switch (Option C1) is a diaphragm type device that senses the airpressure across the heater surface closing the electrical switch and allowing the heater to be activated. This device assures airflow is present before allowing the heaterto energize. The airflow switch is available for either positive or negative air pressure. The pressure differential is .05”+ .02 “. This device is position-sensitive and cannot be mounted in a flat horizontal position.________________________________________________________________________________________________________
TRANSFORMERControl transformers are available mounted in the control panel for primary voltages of 120, 208, 240, 277 and 480 with secondary voltages of 24, 208, 240. A Class II transformer (Option D1) may be used only for 24-volt secondary voltage and only up to 3 steps. All transformers are pric ed based on a maximum of 30 AMPS per step. This transformer includes internal primary over-current protection. All other transformer requirements (Option D2) include external primary over-currentprotection. Secondary fusing for use in conjunction with D1 or D2 transformers is available (Option D3).
________________________________________________________________________________________________________
POWER FUSINGUL and NEC require that heaters in excess of 48 AMPS be subdivided into branch circuits of 48 AMPS or less and be protected by fuses (Option F1). These are supplied by Warren Manufacturing. If circuit fusing on heaters of 48 AMPS or less is desired, price Option F3. For fusing per step (less than 48 AMPS per step) price Option F2. The fewest number of fuse blocks required for the particular KW, AMPS, and Steps will be furnished.The over-current protection (fuses) must be sized for 125% of the circuit load.________________________________________________________________________________________________________
BACK-UP (SAFETY) CONTACTORBack-Up contactor (Option B5) is supplied as an addition to the primary controlling contactor or other device and is controlled only by the manual reset cutout. On an over-temperature condition, the back up is to be de-energized.

ACCESSORY OPTIONS
FAN CONNECTIONA set of terminal connections (Option A1) is provided for external connectionto the fan circuit. This option is available for line voltage control only. Internal connection can vary and must be specified as to desired method.________________________________________________________________________________________________________
THERMAL SAFETY DEVICESA disc type automatic reset thermal safety cutout that de-energizes the heaterelement on overheating, and re -energizes the heater element after the temperature has lowered, is provided as standard equipment. The standard cutout temperature is 145ºF.
A disc type manual reset therma l safety cutout (Option E1, 175º F.) can be provided as a secondary limit control in addition to the standard automatic reset. This device requires a reset button to be engaged to restore power to the heater element. The reset button may be located in the control panel door.

HEATER DESIGN FEATURES
UNIQUE ELEMENT DESIGN
Warren Technology’s design criterion for heating element selection is based on actual element operatingtemperature.
Warren selects all elements by its exclusive “Calculated Wire Temperature Method” a method which insures that elements in heaters operate within the designed electrical and temperature requirements, and do not exceed the melting point of the alloy even in still free air.
The system allows Warren to determine the exact operating temperature of the heater elements in specific condition.The elements are designed to operate below the maximum allowable temperature recommended by the element alloys manufacturer under the worst possible condition. This process eliminates most problems associated with hot spots in heaters caused by poor air distribution.
This method of design allows Warren’s Technology to predict operating temperatures and life spans of any given element in our duct heater product line and has resulted in a zero failure rate on units installed in the field over the past 10 years.
COMPUTERIZED SELECTION
A Computer Selection Program developed after years of research insures that Warren Technology’s heater can meet an infinite number of size and voltage requirements. Utilizing a computer insures that every heater is going to perform consistently. Warren can tell exactly how the element is going to operate and how long it can be expected to last under specific requirements. Computer selection of component parts permits completecompatibility utilizing a manufacturing process where all duct heaters are produced from standard componentsincorporated in an exclusive modular design. This computer selection method is applied on all three basic product line categories, including Custom Built (CBK), Stock-Line (SL), and Quick Silver (QS) electric duct heaters.
CERAMIC SUPPORT SYSTEM
Warren Technology utilizes an element support system, which permits the ceramic element supports to expand and contract freely without cracking or breaking. The heavy support frame completely surrounds the individual ceramic insulators while allowing the insulators to “float” freely, eliminating any binding. The modular concept lends itself to selection of pre-determined distances between the exclusive support frames thus assuring optimum element support.
HEATER FRAME
Warren Technology employs the most modern technology available in the industry to construct the heater frames and boxes. Predetermined optimum element support spacing allows the modular concept to offer the choice of virtually any element rack size combination, and yet utilize the cost savings of volume production. All frames and boxes are constructed of 20 gauges, or heavier, hot dipped galvanized steel. The frame is integrally tied to the control box providing solid one-piece construction for ease of installation. Additionally, this construction allows almost any location relationship between the element rack and control box giving unlimited sizing flexibility.
PERMANENT ELECTRONIC FILE
A permanent electronic file is made for each control panel. The electronic file is retained as a future reference.Having this record on file allows Warren Technology to produce identical heaters at a later date, offer precise engineering assistance to the installing contractor or service personnel should it be required, or supplyreplacement parts identical to those originally furnished if necessary. This is a feature offered exclusively by Warren.

ENGINEERING INFORMATION
UL AND NEC REQUIREMENTS
The information listed is offered as a guide for electric duct heater requirements. It is based on the National Electric Code (NEC) and Underwriters Laboratory (UL) Space Heating Standard No. 1096. Although this is intended to assure that these heaters are manufactured to meet NEC and UL requirements, local electrical codes should be considered for compliance.
Over-temperature Protection - UL and NEC requires the manufacturer to provide two types of over-temperature protection. Warren supplies as standard a disc type automatic reset limit, which de-energizes the heater in the event of overheating. A secondary limit, consisting of a replaceable fuse link is provided, which operates at a higher temperature and de-energizes the heater in case of failure of the primary limit.
Over -current Protection - UL and NEC require that a heater in excess of 48 AMPS be subdivided into circuit of less than 48 AMPS each and built-in fusing be provided by the heater manufacturer. The over-current device (fuse or circuit breaker) must be rated for 125% of the circuit load and limited to 60 AMPS maximum. UL requires the over-current protective devices be supplied by the heater manufacturer.
Loss of Airflow Protection - UL and NEC require that a method be provided to prevent the duct heater element from being energized unless the fan circuit is energized and airflow is present. Warren provides a choice of 4 integral methods to meet this requirement: Fan Connection, Fan Control Relay, Fan Interlock Relay and Air Pressure Switch.
Transformer Protection - Transformers are required for heater operation unless an external control voltage source is available and where the heater power voltage is different from the control voltage. UL requirestransformers to have primary over- current protection. The Class II transformer meets this requirement with built-in protection while all other non-Class II transformers supplied are primary fused externally. Secondarytransformer fusing is available as an option to protect the control circuit but is not required by UL
Equipment Grounding - UL requires a grounding lug be installed by the manufacturer for field wiring connection. All Warren heater control panels contain a UL approved grounding lug.
Disconnect Location - NEC requires an equipment disconnect switch be installed at or within sight of the heater. Warren offers factory-installed disconnect switches (or they may be field supplied to comply with thisrequirement).
Contactors - UL requires that the heater manufacturer supply the contactors as a built-in integral component of the heater.
INSTALLATION INFORMATION
Good installation practice dictates certain guidelines be followed. Although the guidelines listed are generalrecommendations, Warren has the unique ability to custom design heaters to specifications involving unusual applications. Consult the factory for deviations to usual installation practices.
• Always consult local codes for compliance.• Follow SMACNA guides and recommendations.• Install heaters with the airflow in the proper direction as indicated by the arrow.• Make electrical connections per UL and NEC.• The heater should be installed 4ft. from air handler unless designed for internal mount or close coupling.• Provide minimum 4ft. clearance from elbows, transitions, extractors, or similar turbulence producing devices.• Reinforce duct where necessary to support the weight of the heater and prevent sagging.• Allow sufficient clearance for servicing and removal if necessary.• Units greater than 50KW should be controlled by a system with a recycling feature that will not allow all steps tobe energized simultaneously. The absence of such a device causes severe damage to the equipment.• The use of discharge air sensing devices to control this heating unit is not factory recommended and may void the warranty.

ELECTRIC DUCT HEATER
MAINTENANCE AND SERVICE INSTRUCTIONS
Warren electric duct heaters are constructed in such a manner that requires little or no maintenance, including parts supplied with your heater.
Always make sure all connections are tight before heater is turned on.
Be sure heater elements are free of dirt and foreign matter.
Units greater than 50KW should be controlled by a system with a recycling feature that will not allow all steps to be energized simultaneously. The absence of such a device causes severe damage to theequipment.
The use of discharge air sensing devices to control this heating unit is not factory recommended and may void the warranty.
Even though your heater requires no periodic maintenance check, if your heater is not functioningproperly, the following are some points to check:
1. Check installation instructions and wiring diagram to make sure heater was wired and installed properly.
2. Check all connections points and make sure they are tight, before initial startup and before each heating season.
3. Fuses…. One of the most common problems. Check to see they are not blown.
4. Automatic hi-limit or manual reset – temperature may be too high because airflow is insufficient.
5. Air filter may be clogged.
6. Is sufficient airflow “even” over coils?
7. Check for transformers and control voltage flow.
8. Make sure that the thermostat is operating properly and current flow is to heater, both control and power voltage.
9. When air pressure switches are used, they must have the proper airflow. Sensing tube should be curved toward the airflow.
10.Internal insulation may be interfering with safety device.
The above are the most common problems. Other problems may be caused by accessories or related items.

INSTALLATION INSTRUCTIONS
Before install ing the heater, inspect thoroughly for shipping damages. Notify carrier immediately if any damage is found.Check all porcelain insulators for breakage and inspect heater element wire to see that none have been deformed.
The minimum air velocity as shown on the heater label is required and must be even across the face of the heater. The temperature of the air entering the heater must not exceed 77° F.
Connect heater as shown on heater schematic wiring diagram. All electrical connections, wire sizes and type and conduit sizes shall meet the National Electric Code.
Main power supply, minimum wire sizes, circuits, fusing, etc. is shown on schematic wiring diagram.
The air duct system should be designed and installed in accordance with the standards of the National Fire Protection Association for the installation of Air-Conditioning and Ventilation Systems. (Pamphlet 90A or 90B)
Heaters should be mounted in the duct far enough away from the blower for any change in the direction of airflow to insure even airflow over the entire face area of the heater. If a heater cannot be mounted at least 48 inches downstream from the blower or a change in direction of airf low baffles must be installed in the duct ahead of the heater to insure even airflow acros s the face of the heater.
Air fi lters, humidifiers, or cooling coils must be at least 48 inches from the nearest heating element.
The heater control circuit or relay contacts are interlocked with the air system of either an integral air pressure switch or a blower relay, which must be wired as indicated on the wiring diagram. If a blower relay has been used (see diagram) the fan motor, or motor controller amperage must not exceed that given on the diagram.
All heaters are suitable for zero clearance bet ween duct and combustible material.
Model CB-HOK heaters must be used with a remote panel and must be wired in accordance with the accompanyingdiagram.
CBK Insert Heater: The heating element is enclosed by a sheet metal wrapper. This wrapper is not to be used as part of the duct. To install, cut a hole in the side of the duct, 1/2" larger than the insert portion. Insert the heating element and fasten control panel to the side of the duct by means of sheet metal screws. If the duct is internally l ined, then use a recessed element equal to the thickness of the internal insulation.
CBKF Flange Mount: The flange portion of the heater is matched to the out -turned flanges of the duct. There is no flange on the control side of the duct. Fasten heater f lan ge to duct f lange by means of sheet metal screws or bolts. Fasten control panel to side of duct by means of sheet metal screws.
BCB Bottom Mount: a sheet metal wrapper encloses the heating element with the heating element being terminated inside a control panel. This entire portion (element and element termination control panel) is to be inserted into the duct from the bottom. Cut a hole in the bottom of the duct 1/2" larger than the insert portion. Insert the element (and panel) and fasten the control box to the bottom of the duct by means of sheet metal screws .
CHECKOUT
Before energizing this equipment for operation be sure that all electrical terminal connections, c lamps, screws, etc. are tight as these may have become loose in shipment. It is advisable to retighten all electrical connections after the equipment has been in operation and the components have reached operating temperature. In addition to the above, the following tests and procedures should be followed.
A) Clean all dirt, dust and moisture from equipment.B) Check for loose terminal connections.C) Check for proper clearances of l ive parts, between phases and to ground and make sure that all required barriers
are in place.D) Check for missing insulation in equipment and on conductors.E) Check for any modifications, alterations, for the use of unapproved parts.F) Check that all fuse and circuit breaker short circuit interrupting ratings are adequate.G) The equipment room or area should be dried of all dampness and moisture accumulations.H) Check conductors run in multiple to insure that they are properly phased.I) Conduct a "megger" test of all equipment and wiring.
For maximum safety on fused feeders of 200 amperes and over, it is recommended that a low amperage test fuse (15 amps or less) be used and the circuit energized without load. This wil l insure the safe interruption of the circuit if a fault exists.
Any modifications or repairs to the equipment without written permission from the factory wil l be done at the instal ler’s own risk and expense.
