1. The furnace area must be kept clear and free of combustible mate-
rials, gasoline and other flammable vapors and liquids.
2. Insulating materials may be combustible. The furnace must be
kept free and clear of insulating materials. The furnace area must
be examined when installed in an attic or other insulated space or
when insulation is added to be sure that the insulation material has
been kept away from the furnace.
3. The furnace needs air for combustion in order to operate properly
and safely. Do not block or obstruct air openings on the furnace,
air openings to the area where the furnace is installed, or spaces
around the furnace.
4. Follow the instructions exactly as shown on the OPERATING
INSTRUCTION LABEL on the furnace or the "START-UP AND
SHUTDOWN INSTRUCTIONS" section of this manual when light-
ing the furnace or turning the furnace off.
5. Should the gas supply fail to shut off or if overheating occurs, shut
off the gas valve to the furnace before shutting off the electrical
supply.
6. Do not use this furnace if any part has been under water. A flood-
damaged furnace is extremely dangerous. Attempts to use the fur-
nace can result in fire or explosion. A qualified service agency
should be contacted to inspect the furnace and replace all gas
controls, control system parts, electrical parts that have been wet
or the furnace if deemed necessary.

7. NEVER ... Store flammable materials of any kind near your fur-
nace. Gasoline, solvents, and other volatile liquids should be
stored only in approved containers outside your home. These
materials vaporize easily and are extremely dangerous.
8. NEVER ... Store cleaning materials near your furnace. Materials
such as bleaches, detergents, powdered cleansers, etc., can
cause corrosion of the heat exchangers.
9. NEVER ... Use the area around your furnace as a storage area
for items which could block the normal flow of air. This flow of air is
required for ventilation of the various furnace components.

FIRE OR EXPLOSION HAZARD
This furnace is designed and approved for use with Nat-
ural Gas and (LP) Propane Gas ONLY. DO NOT BURN
ANY LIQUID FUEL OR SOLID FUEL IN THIS FURNACE.
Burning any unapproved fuel will result in damage to the
furnace heat exchanger, which could result in Fire, Per-
sonallnjury, and/or Property Damage.
SECTION II: INSTRUCTIONS FOR
EXAMINING THE FURNACE
INSTALLATION
It is the owner's responsibility to ensure that an annual inspection of the
entire heating portion of the unit is made by a qualified service agency.
Examine the furnace as outlined below in steps "1 - 8" before each
heating season. Use Figure 1 for visual reference.
3. Examine return connections
For Modular Homes:
a. If the fumace has a return air duct, examine the return air
duct connections to make sure they are physically sound,
sealed to the furnace casing, and the ducts terminate out-
side the space containing the furnace.
b. If the furnace does not have a return air duct, examine the
return air filter rack connections to make sure they are phys-
ically sound, sealed to the furnace casing.
For Manufactured (Mobile) Homes:
a. Examine the return air filter rack connections to make sure
they are physically sound, sealed to the furnace casing.
4. Examine the furnace casing making sure the physical support is
sound without sagging, cracks or gaps. Examine the furnace base
making sure it is physically sound without cracks, gaps or sagging
and has a good seal.
5. Examine the furnace casing for obvious signs of deterioration.
6. Examine the burner flames to make sure they are in good adjust-
ment. Refer to the pictorial sketch shown in Figure 2 as a compari-
son to the actual flame.
