The installation and servicing of this equipment must be
performed by qualied, experienced technicians only.
1. The furnace area and the vicinity of any other gas
appliances must be kept clear and free of combustible
materials, gasoline, and other ammable vapors and
liquids. Also, do not store or use ammable items
such as paint, varnish, or lacquer in the area.
2. Do not store or use chlorine or uorine products
(bleaches, cements, strippers, aerosols) near the unit.
They can corrode the heat exchanger.
3. Do not use the furnace closet as storage for brooms,
mops, brushes and oily rags or cloths. The area must
be kept clear, clean and free of lint. Furnace must
be kept free and clear of exposed or loose insulation
materials in the area of installation. Examine the
furnace area when the furnace or additional insulation
is added since some insulation materials may be
combustible.
4. Make sure the furnace is always connected to an
approved vent, in good condition, to carry combustion
products outdoors.
5. Familiarize yourself with the controls that shut o the
gas and electrical power to the furnace. If the furnace
is to be shut down at the end of the heating season,
turn o both the gas and electrical power. For safety,
always turn the gas and electrical power o before
performing service or maintenance on the furnace.
6. Establish a regular maintenance schedule to insure

7. Make certain the required clearances for the furnace
are always maintained. These clearances are listed
on the furnace clearance label. If any question
develops, contact the installer of the furnace or
another qualied servicer.
Examine the furnace installation to determine the following:
1. All ue product carrying passages external to the
furnace (i.e. chimney, vent connector) are clear and
free of obstructions.
2. The vent connector is in place, slopes upward and is
physically sound without holes or excessive corrosion.
3. The return air duct connection is physically sound,
sealed to the furnace casing, and terminates outside
the space containing the furnace.
4. The physical support of the furnace is sound without
sagging, cracks, or gaps around the base so as to
provide a seal between the support and the base.
5. There are no obvious signs of deterioration of the
furnace.
6. Check for proper burner ame performance. Flame
should extend directly outward from burners without
curling, oating, or lifting o.
WARNING
Improved construction and additional insulation in homes
have reduced the heat loss and made these homes much
tighter around doors and windows so that air inltration
is minimal. This creates a problem to supply ventilation
and/or combustion air for gas red or other fuel burning
appliances. Any use of appliances that pull air out of the
house (clothes dryers, exhaust fans, replaces, water
heaters, non-direct vent furnaces, etc.) could reduce
combustion air to the furnace.
If fuel-burning appliances are starved for air, the ue gases
produced may not vent outdoors properly. These ue
gases may include carbon monoxide.
