WARNING
Safety Rules
Your furnace is built to provide many years of safe and dependable
service providing it is properly installed and maintained. Howev-
er,abuse and/or improper use can shorten the life of the furnace and
create hazards for you, the owner.
A.
The U.S. Consumer Product Safety Commission recom-
mends that users of gas--burning appliances install car-
bon monoxide detectors. There can be various sources
of carbon monoxide in a building or dwelling. The
sources could be gas--fired clothes dryers, gas cooking
stoves, water heaters, furnaces, gas--fired fireplaces,
wood fireplaces, and several other items. Carbon mon-
oxide can cause serious bodily injury and/or death. Car-
bon monoxide or “CO” is a colorless and odorless gas
produced when fuel is not burned completely or when
the flame does not receive sufficient oxygen.
Therefore, to help alert people of potentially dangerous
carbon monoxide levels, you should have carbon mon-
oxide detectors that are listed as complying with a stan-
dard by a nationally recognized agency (e.g. ANSI/UL
2034--2002, CSA 6.19--01, or International Approval Ser-
vices 6--96) installed and maintained in the building or
dwelling (see Note below).
B. There can be numerous sources of fire or smoke in a building
or dwelling. Fire or smoke can cause serious bodily injury,
death, and/or property damage. Therefore, in order to alert
people of potentially dangerous fire or smoke, you should
have fire and smoke detectors that are listed by Underwriters
Laboratories installed and maintained in the building or
dwelling (see Note below).
Note:
The manufacturer of your furnace does not test any detec-
tors and makes no representations regarding any brand or
type of detector.
C. To ensure safe and efficient operation of your furnace, you
should do the following:
1. T
horoughly read this manual and labels on the furnace.
This will help you understand how your furnace operates and
the hazards involved with gas and electricity.
2.
The furnace area must be kept clear and free of combus-
tible materials, gasoline, and other flammable vapors
and liquids
.
3.
Do not use this furnace if any part has been underwater.
A flood--damaged furnace is extremely dangerous. At-
tempts to use the furnace can result in fire or explosion.
Immediately call a qualified service agency to inspect
the furnace and to replace all control system parts, elec-
trical parts, and gas controls which have been wet or the
furnace, if deemed necessary.
4.
Never block or obstruct the openings on the furnace, or
any ducts that provide air to the furnace.
Air must be pro-
vided for proper and safe operation of the furnace for com-
bustion and ventilation of flue gases.
See the “
Combustion
Air (Your Safety)
section of this manual.
5.
Familiarize yourself with the possible air starvation sig-
nals. Check the combustion air supply.
Some models use
air drawn from outdoors, See
Figure 3
. Other models and
other appliances use combustion air from inside the struc-
ture. Air starvation signals are given in the following
“Com-
bustion Air (Your Safety)”
. section of this manual. If any of the
signals are noticed, perform a combustion air check as
shown in the following
Combustion Air Checks
section of this
manual or call a qualified service agency. If you add weather
stripping, storm windows, insulation, an additional fuel burn-
ing appliance, or remodel the structure, a combustion air
check MUST be accomplished after the addition
6.
Maintain safety and service clearances from the furnace.
These clearances are listed on the furnace rating plate. Keep
the furnace area clean and free of combustible materials at
all times. Never store gasoline, paint, aerosol cans, waxes,
bleaches, dry cleaning fluid or items such as paper or rags
near the furnace.
7.
Examine the furnace area when the furnace or additional
insulation is added since some insulation materials may
be combustible.
Furnace must be kept free and clear of ex-
posed or loose insulation materials in the area of installation.
8.
Should the gas supply fail to shut off or if overheating oc-
curs, shut off the gas valve to the furnace before shut-
ting off the electrical supply
. Read the label on the front of
the furnace and the Operating Your Furnace section of this
manual for steps to turn off the furnace.
9.
Familiarize yourself with all controls.
Make sure you know
how to shut off the gas and the electrical power to the fur-
nace. Read the label on the front of the furnace and the Oper-
ating Your Furnace section of this manual for steps to start
and turn off the furnace. If the furnace is to be shut down for
an extended length of time (example; remodeling project),
turn off both the gas and the electrical power. For safety, al-
ways turn them off before performing service or maintenance
on the furnace.
10.
Establish a regular service and maintenance schedule.
This will ensure efficient and safe operation of the furnace. It
is recommended that you have a qualified service agency
perform a complete check on the furnace before each heat-
ing season. See furnace
Qualified Agency Checks and Com-
bustion Air Checks
section of this manual.
11.
Monthly Inspection
. A properly adjusted gas furnace
should not require cleaning at frequent intervals, but it should
be inspected regularly to ensure safe and efficient operation.
A brief monthly inspection is recommended that does not re-
quire disassembly. Examine the furnace installation to deter-
mine that:
a. Check the return air duct connection. The duct connection
must be physically sound, sealed to the furnace casing
and must terminate outside the space containing the fur-
nace.
b. All flue gas carrying areas external to the furnace (i.e.
chimney, vent connector) are clear and free of obstruc-
tions.
c. The vent connector is in place, slopes upward and is
physically sound without holes or excessive corrosion.
