• Air openings on the top or front of the furnace and openings in
closet doors or walls must never be restricted. If the furnace is
operated without adequate air for combustion, the flame roll-out
switch will open, turning off the gas supply to the burners. This
indicates that a serious problem with the burners has occurred and
must be corrected immediately. Only a licensed HVAC technician
can reset this switch.
• Your furnace and its venting system should be inspected annually
by a licensed HVAC technician. The filter should be inspected at
least once a month. See the Maintenance Information on
page
6
.
• Before you remodel a room near the furnace, consult with a local
code official or the National Fuel Gas Code to make sure you
will be in compliance with supplying adequate air for combustion.
By erecting new walls, it is sometimes possible to inadvertently
restrict the furnace’s air supply. You can find more information
about supplying combustion air in the NFGC, which is available
at many libraries.
CLEARANCES TO COMBUSTIBLES
WARNING:
Do not place combustible materials on or against the
furnace cabinet or vent pipe. The area around the
furnace must be kept clear and free of combustible
materials, gasoline and other flammable vapors and
liquids. A fire or explosion may result causing property
damage, personal injury or loss of life. Failure to follow
the safety warnings exactly could result in serious
injury, death or property damage.
The furnace is designed to have certain clearances to combustible
items such as wood, paper, etc. Some types of insulation are
combustible. If your furnace is installed in an attic, near unfinished
walls, or in other insulated space, keep area surrounding the furnace
free of insulating material. See
Figure 1 below.
IMPORTANT NOTE
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!
En cas de température excessive, ou s’il est impossible de couper
l’alimentation en gaz, fermer le robinet manuel d’alimentation en gaz du
générateur d’air chaud avant de couper l’alimentation électrique
VENTING SYSTEM
WARNING:
CARBON-MONOXIDE POISONING HAZARD
Failure to folow instructions could result in severe
personal injury or death due to carbon-monoxide
poisoning if combustion products infiltrate into
the building.
Check that all oepnings in the outsdie wall around
the vent (and air intake) pipe(s) are sealed to prefent
infiltration of combustion products into the building.
Check that furnace vent (and air intake) terminal(s)
are not obstructed in any way during all seasons.
AVERTISSEMENT :
RISQUE D’INTOXICATION AU MONOXYDE
DE CARBONE
Si ces directives ne sont pas suivies, cela peut entraîner
des blessures graves ou une intoxication au monoxyde de
carbone pouvant causer la mort, si des produits de combustion
s’infiltrent dans le bâtiment.
Vérifier que toutes les ouvertures pratiquées dans le mur
extérieur autour du ou des tuyaux d’évent (et de la prise d’air)
sont scellées de manière à empêcher l’infiltration de produits
de combustion dans le bâtiment.
Veiller à ce que la ou les sorties de l’évent de l’appareil
de chauffage (et la prise d’air) ne soient, en aucune façon,
obstruées, quelle que soit la saison
WARNING:
It is extremely important that the furnace receives an
unobstructed flow of clean, fresh air to properly burn
the fuel gas. If this flow of air is restricted, the partially
burned combustion gases may create dangerous
amounts of carbon monoxide - a colorless, odorless
gas that is a deadly poison that can cause personal
injury or death. This could create the production of
excessive amounts of Carbon Monoxide - a colorless,
odorless gas that is a deadly poison that could result
in serious personal injury or death.
Do not block any openings that are supplying fresh air
to the room or closet the furnace is in. Your furnace
obtains its air through a pipe to the outdoors, do not
allow the inlet of the pipe to become blocked.
• For proper and safe operation, this furnace requires unrestricted
airflow for combustion and ventilation. Do not block or obstruct air
openings on the furnace, air openings around the furnace area
or the spacings around the furnace.

SHUTTING DOWN THE FURNACE
If you need to shut down your furnace for service or maintenance,
shut off the gas valve to the furnace before shutting off the electrical
service. Remove the door panel from the front of the furnace and
turn the gas valve OFF. See
Figure 2, (page 7). Additional
instructions for shutting down the furnace can be found on
page
7
. If your installation has a manual gas shutoff valve on the gas
supply pipe, shut this off, then shut off the electric to the furnace.
