I. General Information
This furnace is built to provide many years of safe and de-
pendable service, providing it is properly installed and main-
tained. However, abuse and/or improper use can shorten
the life of the furnace and create hazards for you, the home-
owner.
WARNING
This product contains or produces a chemi-
cal or chemicals which may cause serious
illness or death and which are known to the
State of California to cause cancer, birth
defects or other reproductive harm.
WARNING
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 appli-
ances must be kept clear and free of combustible mate-
rials, 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 prod-
ucts 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 effi-
cient 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.
WARNING
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, con-
tact 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 pro-
vide 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 for adjustment.
