SPECIFIC SAFETY RULES AND PRECAUTIONS

1.Only Natural gas or Propane (LP) gas are approved for use with this furnace.

2.Install this furnace only in a location and position as specified in these instructions.

3.A gas-fired furnace for installation in a residential garage must be installed as specified in these instructions.

4.Provide adequate combustion and ventilation air to the furnace space as specified in these instructions.

5.Combustion products must be discharged outdoors. Connect this furnace to an approved vent system only, as specified in SEC- TION VII of these instructions.

6.Test for gas leaks as specified in these instructions.

FIRE OR EXPLOSION HAZARD

Failure to follow the safety warnings exactly could result in serious injury, death or property damage.

Never test for gas leaks with an open flame. Use a commercially available soap solution made specifically for detection of leaks to check all connections. A fire or explosion may result causing prop- erty damage, personal injury or loss of life.

7.Always install the furnace to operate within the furnace’s intended temperature rise range. Only connect the furnace to a duct system which has an external static pressure within the allowable range, as specified on the furnace rating plate.

8.When a furnace is installed so that supply ducts carry air circulated by the furnace to areas outside the space containing the furnace, the return air shall also be handled by duct(s) sealed to the fur- nace casing and terminating outside the space containing the fur- nace.

9.It is permitted to use the furnace for heating of buildings or struc- tures under construction where the application and use must com- ply with all manufacturer’s installation instructions including:

•Proper vent installation;

•Furnace operating under thermostatic control;

•Return air duct sealed to the furnace;

•Air filters in place;

•Set furnace input rate and temperature rise per rating plate marking;

•Means for providing outdoor air required for combustion;

•Return air temperature maintained between 55ºF (13ºC) and 80ºF (27ºC);

•The air filter must be replaced upon substantial completion of the construction process;

•Clean furnace, duct work and components upon substantial completion of the construction process, and verify furnace- operating conditions including ignition, input rate, temperature rise and venting, according to the manufacturer’s instructions.

10.When installed in a Non-HUD-Approved Modular Home or building constructed on-site, combustion air shall not be supplied from occupied spaces.

11.The size of the unit should be based on an acceptable heat loss calculation for the structure. ACCA, Manual J or other approved methods may be used.

SAFETY REQUIREMENTS

This product must be installed in strict compliance with the installa- tion instructions and any applicable local, state, and national codes including, but not limited to building, electrical, and mechanical codes.

•Refer to the unit rating plate for the furnace model number, and then see the dimensions page of this instruction for return air ple- num dimensions in Figure 14, "Dimensions". The plenum must be installed according to the instructions.

•Provide clearances from combustible materials as listed under Clearances to Combustibles.

•Provide clearances for servicing ensuring that service access is allowed for both the burners and blower.

•These models ARE NOT CSA listed or approved for installation into a HUD Approved Modular Home or a Manufactured (Mobile) Home.

•This furnace is not approved for installation in trailers or recre- ational vehicles.

•Furnaces for installation on combustible flooring shall not be installed directly on carpeting, tile or other combustible material other than wood flooring.

•Check the rating plate and power supply to be sure that the elec- trical characteristics match. All models use nominal 115 VAC, 1 Phase, 60-Hertz power supply. DO NOT CONNECT THIS APPLI-

ANCE TO A 50 HZ POWER SUPPLY OR A VOLTAGE ABOVE 130 VOLTS.

•Furnace shall be installed so the electrical components are pro- tected from water.

•Installing and servicing heating equipment can be hazardous due to the electrical components and the gas fired components. Only trained and qualified personnel should install, repair, or service gas heating equipment. Untrained service personnel can perform basic maintenance functions such as cleaning and replacing the air filters. When working on heating equipment, observe precau- tions in the manuals and on the labels attached to the unit and other safety precautions that may apply.

COMBUSTION AIR QUALITY (LIST OF CONTAMINANTS)

The furnace requires OUTDOOR AIR for combustion when the furnace is located in any of the following environments.

•Restricted Environments

•Commercial buildings

•Buildings with indoor pools

•Furnaces installed in laundry rooms

•Furnaces installed in hobby or craft rooms

•Furnaces installed near chemical storage areas

•Chemical exposure

The furnace requires OUTDOOR AIR for combustion when the furnace is located in an area where the furnace is being exposed to the follow- ing substances and / or chemicals.

•Permanent wave solutions

•Chlorinated waxes and cleaners

•Chlorine based swimming pool chemicals

•Water softening chemicals

•De-icing salts or chemicals

•Carbon tetrachloride

•Halogen type refrigerants

•Cleaning solvents (such as perchloroethylene)

•Printing inks, paint removers, varnishes, etc.

•Hydrochloric acid

•Cements and glues

•Antistatic fabric softeners for clothes dryers

•Masonry acid washing materials

When outdoor air is used for combustion, the combustion air intake duct system termination must be located external to the building and in an area where there will be no exposure to the substances listed above.
