Examine the furnace installation to determine the following:
1. All flue product carrying passages 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 physi-
cally sound without holes or excessive corrosion.
3. The return air duct connection is physically sound, sealed to
the furnace casing, and terminates outside the space con-
taining the furnace.
4. The physical support of the furnace is sound without sag-
ging, cracks, or gaps around the base so as to provide a seal
between the support and the base.
5. There are no obvious signs of deterioration of the furnace.
6. Check for proper burner flame performance. Flame should
extend directly outward from burners without curling, float-
ing, or lifting off.

SUFFICIENT FRESH AIR FOR PROPER
FLUE GASES MUST BE SUPPLIED
SUPPLIED INTO THE FURNACE
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 appli-
ances that pull air out of the house (clothes dryers, exhaust fans,
fireplaces, water heaters, non-direct vent furnaces, etc.) could
reduce combustion air to the furnace.
If fuel-burning appliances are starved for air, the flue gases pro-
duced may not vent outdoors properly. These flue gases may
include carbon monoxide.

CARBON MONOXIDE POISONING HAZARD
Special Warning for Installation of Furnaces or Air Handling Units in
Enclosed Areas such as Garages, Utility Rooms or Parking Areas
Carbon monoxide producing devices (such as an automobile, space
heater, gas water heater, etc.) should not be operated in enclosed areas
such as unventilated garages, utility rooms or parking areas because of
the danger of carbon monoxide (CO) poisoning resulting from the exhaust
emissions. If a furnace or air handler is installed in an enclosed area such
as a garage, utility room or parking area and a carbon monoxide producing
device is operated therein, there must be adequate, direct outside
ventilation.
This ventilation is necessary to avoid the danger of CO poisoning which
can occur if a carbon monoxide producing device continues to operate in
the enclosed area. Carbon monoxide emissions can be (re)circulated
throughout the structure if the furnace or air handler is operating in any
mode.
CO can cause serious illness including permanent brain damage or death.
Carbon monoxide or "CO" is a colorless and odorless gas pro-
duced when fuel is not burned completely or when the flame
OF
does not receive sufficient oxygen.

The air for combustion and ventilation can also (where local
codes permit) be obtained from the surrounding unconfined
space or louvered closet door. Observe the following precau-
tions concerning air availability:
• When a furnace is installed in a closet and the closet door
is louvered, DO NOT OBSTRUCT LOUVERS. Louvers must be
open and clear to provide combustion air to the furnace.
• When a furnace is installed in a confined space within a
home and the air for combustion and ventilation enters the
space through ducts from the outside, be sure to routinely
check the entering and outlet, grilled openings to verify that
they are always clear and clean.
• Do not partition off a small area around the furnace utiliz-
ing a non-louvered door. This could obstruct the combus-
tion air from reaching the furnace.
