Read this manual and follow its instructions and
adhere to all Cautions and Warnings in the manual
and on the unit. Consult a qualified service technician for installation, adjustment and maintenance.
Failure to observe and follow Cautions, Warnings
and instructions may result in death, bodily injury,
or property damage.
Safety Rules
Your unit is built to provide many years of safe and dependable
service providing it is properly installed and maintained. However,
abuse and/or improper use can shorten the life of the unit and
create hazards for you, the owner.
A. The U.S. Consumer Product Safety Commission recom-
mends that users of gas--burning appliances install carbon
monoxide detectors. There can be various sources of c arbon monoxide in a building or dwelling. The sources could
be gas--fired clothes dryers, gas cooking stoves, water
heaters, furnaces, gas--fired fireplaces, wood fireplaces,
and several other items. Carbon monoxide c an cause serious bodily injury and/or death. Therefore, to help alert
people of potentially dangerous carbon monoxide levels,
you should have carbon monoxide detectors listed by a nationally recognized agency (e.g. Underwriters Laboratories
or International Approval Services) installed and maintained in the building or dwelling (see Note below).
B. There can be numerous sources of fire or smoke in a build-
ing or dwelling. Fire or smoke can cause serious bodily injury, death, and/or property damage. Therefore, in order to
alert people of potentially dangerous fire or smoke, you
should have fire and smoke detectors listed by Underwriters
Laboratories installed and maintained in the building or
dwelling (see Note below).
Note: The manufacturer of your furnace does not test any detec-
tors and makes no representations regarding any brand or
type of detector.
C. To ensure safe and efficient operation of your unit, you
should do the the following:
1. Thoroughly read this manual and labels on the unit.
This will help you understand how your unit operates and
the hazards involved with gas and electricity.
2. Do not use this unit if any part has been under water.Immediately call a qualified service technician to inspect the
unit and to replace any part of the control system and any
gas control which has been under water.
3. Never obstruct the vent grilles, or any ducts that pro-
vide air to the unit. Air must be provided for proper combustion and ventilation of flue gases.
4. Familiarize yourself with the possible air starvation sig-
nals. These are outlined in the Combustion Air section.
5. Check the combustion air supply. Some models use air
drawn from outside, See Figure 2. Other models and other
appliances use combustion air from inside the structure. Air
starvation signals are given on this page. If any of the signals are noticed, perform a combustion air check as shown
on page 4 or call a service technician. 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.
441 02 2001 06
6. Maintain safety and service clearances from the unit.
These are listed on Unit Clearance Label on the cabinet.
Keep the unit area clean and free of combustible materials
at all times. Never store gasoline, paint, aerosol cans,
waxes, bleaches, dry cleaning fluid or items such as paper
or rags near the unit.
7. Examine the furnace area when the furnace or addition-
al insulation is added since some insulation materials
may be combustible. Furnace must be kept free and clear
of exposed or loose insulation materials in the area of installation.
8. Check the return air duct connection. The duct connection must be physically sound, sealed to the furnace casing
and must terminate outside the space containing the furnace.
9. Familiarize yourself with all controls. Make sure you
know how to shut off the gas and the electrical power to the
unit. If the unit is to be shut down for an extended length of
time (example; remodeling project), turn off both the gas
and the electrical power.For safety,always turn them off be fore performing service or maintenance on the unit.
10. Establish a regular service and maintenance schedule.
This will ensure efficient and safe operation of the unit. It is
recommendedthat youhave a qualified service agency perform a complete check on the unit before each heating season. See unit Maintenance “Service Technician Checks”.
Combustion Air ( Your Safety)
!
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 the same
space may also be using indoor air for ventilation
and/or combustion.
Lack of combustion air will result in carbon monoxide gas which could cause death or serious bodily
injury.
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 combustionand ventilation of flue gases. The use of exhaust
fans, fireplaces, clothes dryers, and other appliances consume air
or vent it outside.
If the appliances or heating unit can’t get enough air, two conditions may result:
1. The appliance or heating unit may produce carbon monox ide gas.
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.
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
User’s Information Manual
3. Smoke from the fireplace won’t draw up the chimney.
!
If you experience headaches, nausea, or dizziness,
carbon monoxide may be present.
Leave the house immediately and call your gas
supplier.
Carbon monoxide poisoning can result in death
from asphyxiation or serious bodily injury.
Combustion Air Checks
If any of the signals are noticed, perform a combustion air check or
call a service technician. 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 inches from the draft hood opening.
Reference Figure 1 which shows a water heater draft hood.
Figure 1
Typical Gas
Water Heater
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 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.
!
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 inches) near
the appliance until a permanent air duct is
installed. Contact a qualified service agency .
Carbon monoxide poisoning can result in death
from asphyxiation or serious bodily injury.
4
Water Heater Draft Hood
Draft HoodVent Pipe
Match
If draft hood spillage is indicated:
1 . Check for plugged flue connectors and chimneys. Check
and repair stoppage and test again.
2. If you have a fireplace, open a window or door near the fire place 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.
4. Spillage means air starvation and a fresh air duct or air intakes must be installed to provide air directly to the area
around the unit. These MUST comply with local and state
building codes or in their absence with the National Fuel
Gas Code NFPA 54 ANSI Z223.1, Current edition or in Canada the National Standard CAN/CGA 1--B149.
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. (Donot perform
this test in the kitchen, cooking vapors may produce inaccurate results.)
A good relative humidity is one just high enough to barely startcondensation 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 unit 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 Unit
Figure 2 shows the location of the components in the unit.
Circulating Air Blower
The blower circulates room air through the unit, 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 unit will
shut off. The b lower will continue to run until the unit cools down.
441 02 2001 06
User’s Information Manual
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 unit, on the heating speed unless a call for
cooling is initiated. Blower speed will correspond to the mode of
operation of the unit. 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--programmedto 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 Figure 2 or Figure 3 for
rating plate location.
Door Interlock Switch
All the electrical power for the unit goes through the door interlock
switch. The interlock s witch interrupts electrical power to the unit
when the blower door is removed. The unit will not operate until the
blower door is reinstalled.
Fan Control
The fan/delay control provides power to the circulating air blower
to keep it on until the unit cools down.
The fan off setting can be adjusted if the fan remains on long
enough that cool drafts are felt in the room after the furnace shuts
off.
The delay is set by moving a set of switches on the control. The
Wiring Diagram located on the inside of the blower door shows the
various delay combinations. Refer to Figure 2 or Figure 3 for
location of the control.
If you are unsure how to set the Fan Control, contact a Qualified
Service Technician.
Electronic Ignition Module/Gas Valve
When the thermostat calls for heat it completes a circuit to theelectronic ignition module. The module sends an electrical signal
which ignites the pilot, then opens the gas valve.
When the flame is firmly established the ignitor goes off. If there is
a malfunction, the gas valve automatically shuts off the gas.
Pressure Switches
The unit is equipped with one or two pressure switches that shut
down the unit under various flue conditions. The switches are connected to the furnace by factory supplied tubing.
