Air Requirements

WARNING
To avoid death, personal injury or property
damage, enough fresh air for proper com-
bustion and ventilation of flue gases must
be provided to this furnace. Most homes re-
quire outside air to be supplied into the fur-
nace area.
Improved construction and additional insulation in homes
have reduced the heat loss and made these homes much
tighter around doors and windows so that air infiltration is
minimal. This creates a problem to supply ventilation and/or
combustion air for gas fired or other fuel burning appliances.
Any use of appliances that pull air out of the house (clothes
dryers, exhaust fans, fireplaces, etc.) increases this prob-
lem and appliances could be starving for air.
If fuel-burning appliances are starved for air, the flue gases
which these appliances produce as they operate may not
vent outdoors properly, but remain in the home instead.
These flue gases may include carbon monoxide.

WARNING
Death or personal injury from asphyxiation
can result from exposure to carbon monox-
ide.
Carbon monoxide or "CO" is a colorless and odorless gas
produced when fuel is not burned completely or when the
flame does not receive sufficient oxygen.

Be aware of these air starvation signals which indicate
conditions that may result in carbon monoxide or that
carbon monoxide may be present:
1. Headaches-Nausea-Dizziness.
2. Excessive humidity-heavily frosted windows or a moist
"clammy" feeling in the home.
3. Smoke from a fireplace won't draw up the chimney.
4. Flue gases won't draw up the appliance vent pipe.
WARNING
It is vitally important that the furnace have
proper venting. GUC, GUX, GUD or GDC
model furnaces must never be common
vented with another gas fired appliance. Any
alteration to any venting system must be in
accordance with local and national codes,
and the manufacturer's instructions.
Combustion Air (GUC, GUX, GUD and GDC - One Pipe
System)
Normally the air for combustion and ventilation can be ob-
tained from the surrounding unconfined space or louvered
closet door.
• When a furnace is installed in a closet and the closet
door is louvered DO NOT OBSTRUCT LOUVERS. Lou-
vers must be open and clear to provide combustion air
to the furnace.
• When the furnace is installed in a confined space within
a home and the air for combustion and ventilation en-
ters the space through ducts from the outside...be sure
to check the entering and outlet (grilled) openings so
that they are always clear and clean.
IMPORTANT NOTE: Do not partition off a small area around
the furnace including a non louvered door. This could ob-
struct the combustion air from reaching the furnace.
