For your Safety (continued)

H Carbon monoxide

The U.S. Consumer Product SafetyCommission strongly recommends theinstallation of carbon monoxidedetectors in buildings in whichgas-burning equipment is installed.Carbon monoxide (CO) is a colorless,odorless gas, which may be producedduring incomplete combustion of fueland/or when the flame does not receivean adequate supply of combustion air.

Carbon monoxide can cause severepersonal injury or loss of life.

Therefore, carbon monoxide detectorsthat are in compliance with a nationallyrecognized standard (e.g. ANSI/UL2034-2002, CSA 6.19-01) should beinstalled and maintained in buildings thatcontain gas-burning equipment.

Note:Viessmann does not test any detectorsand makes no representation regardingany brand or type of detector.

H For safe operation

We recommend that you frequently:- Check for debris which could obstructthe flow of flue gases. The vent orchimney must not be blocked. Ablocked or partially blocked vent orchimney can cause flue gases to leakinto the structure. Flue gases leakinginto the house can cause injury ordeath. Blocked or partially blockedchimneys must have the blockageremoved by a qualified heatingcontractor.

- Check pressure gage for correctsystem (water) pressure. Check forwater on the floor from the dischargepipe of the pressure relief valve or anyother pipe, pipe joint, valve or airvent.

- Check for moisture, water, orappearance of rust on the flue gaspipes, their joints as well as ventdampers, or side wall vent terminals(if so equipped).

- Ensure that nothing is obstructing theflow of combustion and ventilation airand no chemicals, garbage, gasoline,combustible materials, flammablevapors and liquids are stored (noteven temporarily) in the vicinity of theboiler.

- Do not allow unsupervised childrennear the boiler.

Service/inspection of the boiler and thesystem is recommended once a year.Maintenance, service and cleaning arespecified in the Installation Instructions.

Before the heating season begins, it isrecommended that the boiler and burnerbe serviced by a qualified heatingcontractor. Service contracts may beestablished through gas suppliers orother licensed contractors in your area.

As there are no user-serviceable partson the boiler, burner or control, theend-user must not perform serviceactivities or adjustments of any kind onsystem components. Failure to heedthis warning can cause propertydamage, severe personal injury, or lossof life.

WARNING

Improper installation, adjustment,service, or maintenance can cause flueproducts to flow into living space. Flueproducts contain poisonous carbonmonoxide gas which can cause nauseaor asphyxiation resulting in severepersonal injury or loss of life.

WARNING

Should overheating occur or the gassupply fail to shut off, do notdisconnect the electrical supply to thepump. Instead, shut off the gas supplyat a location external to the appliance.

CAUTION

The operator/ultimate owner is requiredto have the heating boiler, burners, andcontrols checked, as a minimum onceper year, by the original installer or by acompetent heating contractor familiarwith the equipment. Defects must becorrected immediately.

Service Instructions for Your Heating System

Viessmann strongly recommends inspection/service of the boiler and the system bya licensed professional heating contractor once a year.

Before the heating season begins, the boiler with its burner(s) and direct vent systemshould be serviced by a qualified heating contractor. Service contracts may beestablished through gas suppliers or other licensed contractors in your area.

Regular inspection/service ensures trouble-free, energy-efficient and environmentallyfriendly heating activity of your heating system.

BoilerAll boilers must be cleaned on a regularbasis as debris build-up will result inincreased flue gas temperature, andthus in increased energy consumption.

Notes on operation:H Ensure boiler room and boilerare clean.

H Regularly check heating systempressure on the pressure gage:If the needle of pressure gage isbelow 12 psig, the system pressureis too low; in this case, pleasecontact your heating contractor.
