•When installed in a residential garage, the furnace must be positioned so the burners and ignition source are located not less than 18 inches (457 mm) above the floor and protected from physical damage by vehicles.

II.General Information

WARNING

Possible death, personal injury or property damage due to fire, explosion, smoke, soot, condensation, electrical shock or carbon monoxide may result from improper installation, repair, operation, or maintenance on this product.

To ensure the furnace operates safely and efficiently, it must be installed, operated and maintained in accordance with these installation and operating instructions, all local building codes and ordinances, or, in their absence, with the latest edition of the National Fuel Gas Code, ANSI Z223.1*, and/or CAN/CGA B149 Installation Codes.

The rated heating capacity of the furnace should be greater than or equal to the total heat loss of the area to be heated. The total heat loss should be calculated by an approved method or in accordance with “ASHRAE. Guide” or “Manual J-Load Calculations” published by the Air Conditioning Contractors of America.

TRANSPORTATION DAMAGE

Check the furnace for any shipping damage. If damage is found, contact the company where the furnace was pur- chased.

While checking for transportation damage, remove all pack- aging material and dispose or recycle according to local codes.

THERMOSTAT LOCATION

Locate the thermostat about 5 feet high on a vibration-free inside wall, in an area having good air circulation

Do not install the thermostat where it may be affected by:

•drafts or dead spots behind door, in corners or under cabinets.

•hot or cold air from ducts.

•radiant heat from sun or appliances.

•concealed pipes and chimneys.

•unheated (uncooled) areas behind the thermostat, such as an outside wall.

Consult the instructions packaged with the thermostat for mounting instructions.

III. Air Requirements

COMBUSTION AND VENTILATION AIR

WARNING

Possible death, personal injury or property damage may occur if the furnace and other fuel-burning appliances are not provided with enough fresh air for proper combustion and ventilation of flue gases. Most homes require outside air to be supplied into the furnace area.

Improved construction and additional insulation in build- ings has reduced the heat loss, making these buildings much tighter around doors and windows so air infiltration is minimal. This creates a problem supplying combustion and ventilation air for gas fired and other fuel burning appli- ances. Use of appliances pulling air out of the house (clothes dryers, exhaust fans, fireplaces, etc.) increases this problem causing appliances to starve for air.

This furnace must use indoor air for combustion. It cannot be installed as a direct vent (i.e., sealed combustion) furnace. The burner box is present only to help reduce sound transmission from the burners to the occupied space.

AIR REQUIREMENTS

Most homes will require outside air supplied to the furnace area by means of ventilation grilles or ducts connecting directly to the outdoors or spaces open to the outdoors such as attics or crawl spaces. The following information on air for combustion and ventilation is reproduced from the National Fuel Gas Code NFPA54/ANSI Z223.1 Section 5.3.

5.3.1 General:

(a)The provisions of 5.3 apply to gas utilization equipment installed in buildings and which require air for combustion, ventilation and dilution of flue gases from within the build- ing. They do not apply to (1) direct vent equipment which is constructed and installed so that all air combustion is obtained from the outside atmosphere and all flue gases are discharged to the outside atmosphere, or (2) enclosed furnaces which incorporate an integral total enclosure and use only outside air for combustion and dilution of flue gases.

(b)Equipment shall be installed in a location in which the facilities for ventilation permit satisfactory combustion of gas, proper venting and the maintenance of ambient tem- perature at safe limits under normal conditions of use. Equipment shall be located so as not to interfere with proper circulation of air. When normal infiltration does not provide the necessary air, outside air shall be introduced.
