PERSONAL INJURY, DEATH AND/OR PROPERTY
DAMAGE HAZARD

Failure to observe and follow Cautions, Warnings

and instructions could result in personal

injury, death or property damage.
Read this manual and follow its instructions and

adhere to all Cautions and Warnings in the manual
and on the furnace.

Consult a qualified service agency for
installation, adjustment and maintenance.

SafetyRules

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 improperuse 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 personal injury and/or death. Carbon
monoxide or "CO" is a colorless and odorless gas pro-
duced 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. ANSl/UL
2034-2008, 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 personal 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 Labora-
tories installed and maintained in the building or dwelling

(see Note below).

Note: The manufacturer of your furnace does not test any detectors

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. Thoroughly 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
provided for proper and safe operation of the furnace for

combustion and ventilation of flue gases. See the "Com-
bustion Air (Your Safety) section of this manual.

5. Familiarize yourself with the possible air starvation
signals. Check the combustion air supply. Some mod-

els use air drawn from outdoors, See Figure 3. Other mod-
els and other appliances use combustion air from inside the

441 02 2012 01

structure. Air starvation signals are given in the following
"Combustion 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 burning appliance, or remodel the structure,
a combustion air check MUST be accomplished after the

addition

6. Maintain safety and service clearances from the fur-
nace. 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 addi-
tional insulation is added since some insulation mate-

rials may be combustible. Furnace must be kept free and
clear of exposed or loose insulationmaterials inthe area of

installation.

8. Should the gas supply fail to shut off or if overheating
occurs, shut off the gas valve to the furnace before
shutting 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

furnace. Read the label on the front of the furnace and the

Operating Your Furnace section of this manual for steps to
start and turn off the furnace. If the furnace isto be shut

down for an extended length of time (example; remodeling
project), turn off both the gas and the electrical power. For
safety, always turn them off before performing service or

maintenance on the furnace.

10. Establish a regular service and maintenance sched-
ule. This will ensure efficient and safe operation of the fur-

nace. It is recommended that you have a qualified service
agency perform a complete check on the furnace before

each heating season. See furnace Quafified Agency
Checks and Combustion Air Checks section of this manu-

al.

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 require disassembly. Examine the furnace instal-

lation to determine 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.

d. (Upflow or downflow installations with duct connection at

bottom only.) The physical support of the furnace is sound
without sagging, cracks, gaps, etc., around the base so as

to provide an air seal between the support and the base.

e.There should be no obvious signs of deterioration of the

furnace.
Check that the burner flames are in good adjustment. To

inspect the Main Burner flames itwill be necessary to re-

move the Iouvered door on the front of the furnace, except
for furnaces not having any louvers in the doors. The
doors (no louvers) of these furnaces must remain installed

(to prevent changes in flame appearance) while inspect-

ing the Main Burner flames through the view port inthe
door. Contact a qualified service agency at once if an
abnormal flame appearance is identified.
