SAFETY CONSIDERATIONS
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 wo rds: DANGER, WARNING, and
CAUTION. 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 may 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.
To minimize the possibility of serious personal injury, fire, furnace
damage, or improper operation; carefully follow these safety
rules:
S Your gas furnace uses air from outside the home for combustion
and vents flue gas to the outdoors. It is not to be installed using
indoor air for combustion. The vent pipe must terminate outside
the structure and must not be obstructed in any way. The
air--intake pipe must terminate outside the structure or in a well
ventilated area that is isolated from the living space and the
garage (e.g. well ventilated attic or crawlspace). Do not block or
obstruct air openings on furnace or spaces around furnace.
S Keep the area around your furnace clear and free of combustible
materials, gasoline, and other flammable liquids and vapors.

Combustion Air (Your Safety)
!
WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury
or death.
All fuel--burning appliances must be provided with enough
fresh air for proper combustion and ventilation of flue gases.
Some models use air from the space in which they are located,
and other appliances in thesamespace may also be using
indoor air for ventilation and/or combustion.
New materials and methods are being used in construction and
remodeling which result in lower energy costs for heating and
cooling. It may also mean your appliances may not be getting
enough air for combustion and ventilation of flue gases. The use of
359AAV
exhaust fans, fireplaces, clothes dryers, and other appliances
consume air or vent it to the outdoors.
If the gas appliances or heating furnace can’t get enough air, two
conditions may result:
1. The appliances or furnace may produce carbon monoxide
gas.
2. The appliance may not vent flue gases properly. The following are signs that your appliances may not be getting
enough air for proper combustion.
Be aware of these signals:
1. Headaches, Nausea, Dizziness
2. Excessive humidity----heavily frosted windows or a moist
“clammy” feeling in the structure.
3. Smoke from the fireplace won’t draw up the chimney.
!
WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury
or death.
If you experience headaches, nausea, or dizziness, carbon
monoxide may be present. Leave the house immediately and
call your gas supplier.
Combustion Air Checks
If any of the above signals are noticed, perform a combustion air
check or call a qualified service agency. If you add weather
stripping, storm windows, insulation, an additional fuel burning
appliance, or remodel the structure, a combustion air check MUST
be accomplished after the addition.
Make the inspection as follows:
1. Close all doors and windows. If you have a fireplace, start a
fire and wait until flames are burning vigorously.
2. Turn on all exhausting devices, such as: kitchen and bathroom exhaust fans and dryers (gas or electric).
3. Turn on all vented gas appliances, such as: heating equipment (includes any room heaters) and water heaters.
4. Wait ten (10) minutes for drafts to stabilize.
5. On appliances with a draft hood, check for spillage by holding a lighted match 2” (50.8 mm)from the draft hood opening. Reference Fig. 1, which shows a water heater draft
hood.

a. Match flame pulls toward draft hood.
This indicates no spillage and that appliance is getting
enough air for combustion. Return exhausting devices
and appliances to the condition in which you found
them.
b. Match goes out or flame wavers away from draft hood.
This indicates spillage and that appliance is not getting
enough air for combustion.
!
WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury
or death.
Draft hood spillage means there is not enough air for proper
combustion and carbon monoxide may be present.
Keep a window open a minimum of 2” (50.8 mm) near the
appliance until a permanent combustion air duct is installed.
Contact a qualified service agency.

If draft hood spillage is indicated:
1. Check for plugged vent connectors and chimneys. Repair
stoppage and test again.
2. If you have a fireplace, open a window or door near the fireplace and then check for spillage. If spillage stops, do not
use the fireplace until you can supply fresh air by a permanent duct.
3. If you have kitchen and bathroom exhaust fans, turn them
OFF and check for spillage. If spillage stops, do not use exhaust fans until you can supply fresh air by a permanent
duct. Circuit breakers for fans should be turned off and
marked as to why they are off.
4. Spillage means air starvation and that an outdoor air duct or
air intake must be installed to provide air directly to the area
around the furnace. This duct or intake MUST comply with
local and state building codes or in their absence with the
National Fuel Gas Code NFPA 54/ANSI Z223.1--2006 in
the U.S., or the National Standard of Canada, Natural Gas
and Propane Installation Code CSA B--149.1--2006 in
Canada.
Indoor Humidity (Your Comfort)
Relative humidity is important to your health. Proper
humidification helps cut down incidences of respiratory illness. Air
that is too wet may damage the building structure. Air that is too
dry is uncomfortable. A quick way to test for proper humidity is as
follows:
1. Look for frequent fogging or excessive condensation on the
inside of windows. This indicates the indoor humidity level
is too high for outdoor weather conditions.
2. Drop three ice cubes into a glass of water and stir. If, within
three minutes, moisture does not form on the glass, the air is
too dry and a humidifier would be beneficial. (Do not per-
2
form this test in the kitchen, cooking vapors may produce
″
″
inaccurate results.)
A good relative humidity is one just high enough to barely start
condensation along the lower edges or lower corners of the
windows, when it is cold outside. More than that can be damaging.
If the humidity is too high, try these suggestions to lower the
humidity:
1. Reduce setting or discontinue use of humidifier.
2. Use range and bathroom exhaust fans while cooking and
bathing. Open a door or window for a few minutes to bring
in cool drier air.
3. Cook with pans covered.
4. Take shorter baths or showers with cooler water.
5. Install a fresh air intake duct. Cold, dry air brought in from
outside to the furnace area lowers the indoor humidity level.
6. Have appliances checked. A malfunctioning appliance can
contribute water vapor to the structure.
7. If the problem continues, consult a heating contractor about
adding a heat recovery ventilator or air--to --air heat exchanger.
About Your Furnace
Fig. 2 shows the location of the components in the furnace.
Circulating Air Blower
The blower circulates room air through the furnace, air ducts, and
into the rooms of the structure. The blower can be set at the
thermostat for automatic or manual operation. In manual mode the
blower operates continuously. In automatic, the blower does not
come on until a preset time after the gas valve is energized. When
the structure reaches the temperature set on the thermostat, the
furnace will shut off. The blower will continue to run until the
furnace cools down.
Thermostat
There are many types and styles of thermostats. Most thermostats
control both heating and cooling functions and have a Fan Switch
with AUTO and ON settings. On AUTO, the Circulating Air
Blower will cycle on/off with the furnace on the heating speed
unless a call for cooling is initiated. Blower speed will correspond
to the mode of operation of the furnace. If the Fan Switch is
positioned to ON the blower will run continuously.
In addition some thermostats are programmable with multiple set
backs. The set backs can be pre--programmed to lower or raise the
temperature automatically.
Be sure to become familiar with your thermostat.
Rating Plate
The rating plate contains important information for the service
technician and lists the complete model, manufacturing and serial
numbers. You should always provide all these numbers when
requesting parts or if you need service. See Fig. 2 for rating plate
location.
Door Interlock Switch
All the electrical power for the furnace goes through the door
interlock switch. The interlock switch interrupts electrical power to
the furnace when the blower door is removed. The furnace will not
operate until the blower door is reinstalled.
Furnace Control
The furnace control provides power to the circulating air blower to
keep it on until the furnace cools down.
The fan off-- delay setting can be adjusted if the fan remains on long
enough that cool drafts are felt in the room after the furnace shuts
off.
