WARNING
PERSONAL INJURY HAZARD
To avoid personal injury or fire, minimum
clearances to combustible surfaces must be
followed.
7. Make certain the required clearances for the furnace are
always maintained. These clearances are listed on the
furnace nameplate. If any question develops, contact the
installer of the furnace, or another qualified servicer.
Unit Installation
Examine the furnace installation to determine the following:
1. The flue vent pipe is physically sound and sealed. The
vent slopes upward to vent terminal so condensate
drains back toward the furnace. The vent shows no
evidence of leaking or separation at joints or fittings.
2. The return air duct connection is physically sound, sealed
to the furnace casing, and terminates outside the space
containing the furnace.
3. 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.
4. There are no obvious signs of deterioration of the fur-
nace.
5. Check the burner flames to for adjustment.

WARNING
PERSONAL INJURY HAZARD
To avoid possible equipment damage, per-
sonal injury, fire or death, the following in-
structions must be observed regarding unit
location, air requirements and operating pro-
cedures.
Unit Location
1. The furnace area and the vicinity of any other gas
appliances must be kept clear and free of combustible
materials, gasoline, and other flammable vapors and
liquids. Also, do not store or use flammable items such as
paint, varnish, or lacquer in the area.
2. Do not store or use chlorine or fluorine 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 ap-
proved vent, in good condition, to carry combustion
products outdoors.
5. Familiarize yourself with the controls that shut off the gas
and electrical power to the furnace. If the furnace is to be
shut down at the end of the heating season, turn off both
the gas and electrical power. For safety, always turn the
gas and electrical power off before performing service or
maintenance on the furnace.
6. Establish a regular maintenance schedule to insure
efficient and safe operation of the furnace. The furnace
should be checked at the beginning of each heating and
cooling season by a qualified service technician.
