REMARQUE IMPORTANTE
En cas de surchauffe, ou si l’alimentation de gaz omet de
s’arrêter, fermez le robinet de gaz manuel à la fournaise
avant de couper l’alimentation électrique.
COMBUSTION AIR & VENTING SYSTEM
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 chase under the
home to the outdoors. Do not allow the inlet of the
chase 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.
• Do not install home skirting that prevents adequate
combustion air from reaching the furnace.
• 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 burner. 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.
