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.

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.

1.

Examine the heat exchanger, vent/combustion air piping, vent
connectors and chimney to be sure they are clear and free of
obstructions.

2.

Examine the vent pipe making sure it is firmly in place, that it
slopes slightly upward and is physically sound without holes and
all of the connections are secure.

3.

Examine the return-air duct connections to make sure they are
physically sound, sealed to the furnace casing, and the ducts ter-
minate outside the space containing the furnace.

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.

7.

Examine the furnace as outlined above in steps  “1 - 6” before
each heating season. Use Figure 3 for visual reference.
