SAFETY CONSIDERATIONS

!WARNING

FIRE, EXPLOSION, ELECTRICAL SHOCK, AND CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in dangerous operation, personal injury, death, or property damage.

Improper installation, adjustment, alteration, service, maintenance, or use can cause carbon monoxide poisoning, explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage. Consult a qualified service agency, local gas supplier, or your distributor or branch for information or assistance. The qualified service agency must use only factory-authorized and listed kits or accessories when modifying this product.

!CAUTION

FURNACE RELIABILITY HAZARD

Failure to follow this caution may result in unit component damage.

Application of this furnace should be indoors with special attention given to vent sizing and material, gas input rate, air temperature rise, unit leveling, and unit sizing.

Installing and servicing heating equipment can be hazardous due to gas and electrical components. Only trained and qualified personnel should install, repair, or service heating equipment. Untrained personnel can perform basic maintenance functions such as cleaning and replacing air filters. All other operations must be performed by trained service personnel. When working on heating equipment, observe precautions in literature, on tags, and on labels attached to or shipped with furnace and other safety precautions that may apply.

These instructions cover minimum requirements and conform to existing national standards and safety codes. In some instances, these instructions exceed certain local codes and ordinances, especially those that may not have kept up with changing residential construction practices. We require these instructions as a minimum for a safe installation.

!CAUTION

CUT HAZARD

Failure to follow this caution may result in personal injury.

Sheet metal parts may have sharp edges or burrs. Use care and wear appropriate protective clothing, safety glasses and gloves when handling parts, and servicing furnaces.

Wear safety glasses, protective clothing and work gloves. Have fire extinguisher available during start-up and adjustment procedures and service calls.

This is the safety-alert symbol . When you see this symbol on the furnace and in instructions or manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, and CAUTION. These words are used with the safety-alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies a hazard which could result in personal injury or death. CAUTION is used

to identify hazards which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

1.Use only with type of gas approved for this furnace. Refer to the furnace rating plate.

2.Install this furnace only in a location and position as spe- cified in the “Location” section of these instructions.

3.Provide adequate combustion and ventilation air to the furnace space as specified in “Air for Combustion and Ventilation” section.

4.Combustion products must be discharged outdoors. Con- nect this furnace to an approved vent system only, as spe- cified in the “Venting” section of these instructions.

5.Never test for gas leaks with an open flame. Use a com- mercially available soap solution made specifically for the detection of leaks to check all connections, as specified in the “Gas Piping” section.

6.Always install furnace to operate within the furnace’s in- tended temperature-rise range with a duct system which has an external static pressure within the allowable range, as specified in the “Start-Up, Adjustments, and Safety Check” section. See furnace rating plate.

7.When a furnace is installed so that supply ducts carry air circulated by the furnace to areas outside the space con- taining the furnace, the return air shall also be handled by duct(s) sealed to the furnace casing and terminating out- side the space containing the furnace. See “Air Ducts” sec- tion.

8.A gas-fired furnace for installation in a residential garage must be installed as specified in the warning box in the “Location” section.

9.The furnace may be used for construction heat provided that the furnace installation and operation complies with the first CAUTION in the LOCATION section of these in- structions.

10.These Multipoise Gas-Fired Furnaces are CSA (formerly A.G.A. and C.G.A.) design-certified for use with natural and propane gases (see furnace rating plate) and for install- ation in alcoves, attics, basements, closets, utility rooms, crawlspaces, and garages. The furnace is factory-shipped for use with natural gas. A CSA (A.G.A. and C.G.A.) lis- ted accessory gas conversion kit is required to convert fur- nace for use with propane gas.

11.See Fig. 1 for required clearances to combustible construc- tion.

12.Maintain a 1-in. (25 mm) clearance from combustible ma- terials to supply air ductwork for a distance of 36 in. (914 mm) horizontally from the furnace. See NFPA 90B or loc- al code for further requirements.

13.These furnaces SHALL NOT be installed directly on car- peting, tile, or any other combustible material other than wood flooring. In downflow installations, factory access- ory floor base MUST be used when installed on combust- ible materials and wood flooring. Special base is not re- quired when this furnace is installed on manufacturer’s Coil Assembly Part No. CNRV, CNPV, CAP, or CAR or when Coil Box Part No. KCAKC is used. See Fig. 1 for clearance to combustible construction information.
