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.

12.When moving or handling this furnace prior to installation it is rec- ommended to leave the doors on the furnace to provide support and to prevent damage or warping of the cabinet. When lifting the furnace by the cabinet, support the ends of the furnace rather than lifting by the cabinet flanges at the return air openings (bottom or sides) or supply air opening.

13.When lifting the furnace, it is acceptable to use the primary heat exchanger tubes as a lifting point provided that the tubes are lifted at the front of the heat exchangers where attached to the vestibule panel. Do not use the top return bend of the heat exchangers as lifting points as the tubes may shift out of position or their location brackets/baffles.

During installation, doors should remain on the furnace when moving or lifting.

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 12. 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.
