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 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 insulation materials in the 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 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, 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 it will 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 in the
door. Contact
a qualified
service agency at once if an
abnormal
flame appearance
is identified.
