Most states in the USA and jurisdictions in Canada have laws that
require the use of Carbon Monoxide (CO) alarms with fuel burning
products. Examples of fuel burning products are furnaces, boilers, space
heaters, generators, water heaters, stoves/ranges, clothes dryers,
fireplaces, incinerators, automobiles, and other internal combustion
engines. Even if there are no laws in your jurisdiction requiring a CO
Alarm, it’s highly recommended that whenever any fuel burning product
is used in or around the home or business that the dwelling be equipped
with a CO Alarm(s). The Consumer Product Safety Commission
recommends the use of CO Alarm(s). The CO Alarm(s) must be
installed, operated, and maintained according to the CO Alarm
manufacturer’s instructions. For more information about Carbon
Monoxide, local laws, or to purchase a CO Alarm online, please visit the
following website. https://www.kidde.com

WELCOME TO TODAY’S GENERATION OF
COMFORT
Congratulations! Your new gas furnace is a sound investment which will
reward you and your family with years of warm memories winter after
winter.
Not only is your new furnace energy efficient, it is also extremely
reliable. Spend just a few minutes with this booklet to learn about the
operation of your new furnace—and the small amount of maintenance it
takes to keep it operating at peak efficiency. Years went into the
development of your new furnace. Take a little time now to assure its
most efficient operation for years to come.
IMPORTANT FACTS (DO’S AND DON’TS)
DO: READ AND UNDERSTAND THIS MANUAL.
DO: Have your furnace and vent system inspected annually by a
qualified service technician.
DO: Inspect your filter monthly and clean or replace when needed.
DO: Provide adequate airflow to the furnace for efficient combustion
and safe ventilation.
DO: Keep your furnace free and clear of insulating material (some
materials may be combustible. Examine the furnace area when the
furnace is installed or when insulation is added.
DO NOT: Enclose your furnace in an airtight room or seal it behind
solid doors.
DO NOT: Keep combustible materials, gasoline, and other flammable
liquids or vapors around your furnace.
DO NOT: Cover your furnace in any manner.
DO NOT: Store anything (including trash or debris) near your furnace.
DO NOT: In any way block or restrict airflow around your furnace.
DO NOT: In any way block or restrict airflow to your supply air and
return air grills.
DO NOT: Use your furnace room as a broom closet or a place to store
any kind of chemical or cleaner.
DO NOT: Contaminate the air used for combustion of your furnace
with any kind of chemical or fumes. This could also cause heat
exchangers, metal vent systems or components to deteriorate.
NOTE: These chemicals or fumes are present in many products around
the home, such as: water softener salts, any type of household cleaning
product, any type of laundry product, adhesives, paints, varnishes, paint
strippers, waxes and plastics, etc.
During remodeling be sure the combustion air is fresh and
uncontaminated. If these compounds are burned in your furnace, the heat
exchangers and metal vent system may deteriorate.
NOTE: The qualified installer or agency must use only
factory-authorized replacement parts, kits, and accessories when
modifying this product.
This furnace contains safety devices which must be manually reset. If
the furnace is left unattended for an extended period of time, have it
checked periodically for proper operation. This precaution will prevent
problems associated with no heat, such as frozen water pipes, etc (see
“Before You Request a Service Call” section in this manual.)

SAFETY CONSIDERATIONS
Installing and servicing heating equipment can be hazardous due to gas
and electrical components. Only trained and qualified personnel should
install, repair, or service heating equipment.
Untrained personnel can perform basic maintenance functions such as
cleaning or replacing air filters. All other operations must be performed
by trained service personnel. Observe safety precautions in this manual,
on tags, and on labels attached to the furnace, and other safety
precautions that may apply.
Recognize safety information. This is the safety-alert symbol . When
you see this symbol on the furnace and in instructions or manuals, be
alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, and CAUTION.
These words are used with the safety-alert symbol. DANGER identifies
the most serious hazards which will result in severe personal injury or
death. WARNING signifies hazards which could result in personal
injury or death. CAUTION is used to identify unsafe practices which
would result in minor personal injury or product and property damage.
NOTE is used to highlight suggestions which will result in enhanced
installation, reliability or operation.
BEFORE STARTING YOUR FURNACE
Examine the furnace installation to determine that:
1. All flue gas carrying areas external to the furnace (i.e. chimney,
vent connector) are clear and free of obstructions.
2. The vent connector is in place, slopes upward and is physically
sound without holes or excessive corrosion.
3. The return-air duct connection(s) is physically sound, is sealed to
the furnace casing, and terminates outside the space containing the
furnace.
4. The physical support of the furnace is sound without sagging
cracks, gaps, etc. around the base.
5. There are no obvious signs of deterioration of the furnace.
STARTING YOUR FURNACE
Your furnace uses an automatic, hot surface ignition system to light the
burners each time the thermostat signals the furnace to start.
Follow these important safeguards:
Never attempt to manually light the burners with a match or other
source of flame.
A92319
Fig. 3 – Do Not Light Burner with Match
Read and follow the operating instructions on inside of main furnace
door, especially the item that reads as follows:
“Wait 5 minutes to clear out any gas. Then smell for gas, including
near the floor. If you smell gas, STOP! Follow “B” in the safety
information above on this furnace label. If you don’t smell gas, go to
the next step.”
If a suspected malfunction occurs with your gas control system, such
as the burners do not light when they should, refer to the shutdown
procedures on inside of main furnace door, or in the “Shutting Down
Your Furnace” section and call your dealer as soon as possible.
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.
CHECK AIR FILTER: Before attempting to start your furnace, be
sure the furnace filter is clean and in place (see “Performing Routine
Maintenance” section in this manual. Do not run the furnace without
a filter in place. Then proceed as follows:
STEPS FOR STARTING YOUR FURNACE
1. Set your room thermostat to the lowest temperature setting (see
Fig. 4).
A09564
Fig. 4 – Lowest Temperature Setting
2. Close the external manual gas valve (see Fig. 5).
WARNING!
FIRE OR EXPLOSION HAZARD
Failure to follow warnings could result in personal injury, death, or
property damage.
Keep insulation clear of furnace and maintain clearances shown on unit
clearance label.
WARNING!
FIRE AND EXPLOSION HAZARD
Failure to follow this warning could result in personal injury, death or
property damage.
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
and install lockout tag.
