The operation and care of your unit is simple and easy. By fol-
lowing these operating and maintenance procedures, you can
expect to receive better, longer, and more reliable service from
your new appliance.
HERE ARE A FEW DO’S AND DO NOT’S
• DO become familiar with the instructions.
• DO use filters. Check them periodically and make sure that
they are clean.
• DO check to see that your home has adequate insulation,
weatherstripping, caulking, and storm windows. Eliminating in-
filtration of outside air and drafts can save up to 40% of your
fuel bill.
• DO NOT waste fuel by setting your thermostat too high. En-
ergy conservation experts recommend daytime thermostat set-
ting of 68
° F, with a lower setting at night.
• DO NOT turn off the furnace when you expect to be away
for more than a day. Instead, lower the thermostat setting by a
fewdegrees.You canthenrestorenormalcomfortlevelquickly
and save fuel too.
• DO NOT block registers with furniture.
• DO NOT put a lamp, TV, or radio too near your thermostat.
This will cause it to give a false reading.
Here’s How Your Heating System Works
The furnace operates automatically. It is controlled by a ther-
mostat which you set at the temperature most comfortable to
you. When the inside temperature drops below this setting,
your thermostat will turn on the heating system.
Whenthe thermostat calls for heat, power from the transformer
energizes the fan control board. The fan control energizes the
ignition control. The ignition control will light the burner au-
tomatically.
CAUTION
The ability to properly perform maintenance on
this equipment requires certain mechanical skills
and tools. If you are at all uncertain, contact your
dealer for qualified maintenance and service.
!
The electronic fan control will automatically turn on the
blower after 30 sec. Fan on control is not adjustable. The air
moved over the heat exchanger by the blower is warmed and
passes through the ducts to the room registers.
Whenthethermostatissatisfied,thecircuitisde-energizedand
the primary control shuts off the burner. The blower continues
to run until the selectable fan off time period has expired.
The heat sensing switch performs as the furnace high temper-
ature limit switch. If the furnace overheats for any reason, the
limit switch opens, breaking the circuit to the burner. The
blower motor will be energized and as the unit cools the limit
switch will close. This will relight the burner but unless the
overheating condition is corrected, the furnace will continue to
cycle on limit.
This unit is equipped with an interrupted ignition electronic
control. If the main burner does not ignite within 30 sec from
thecallforheat,thecontrolwillgointolockout.The red button
on top of the control must be depressed for 3 sec in order to
resetthe control.The control CANNOT be reset from theroom
thermostat.
HEATING
Preparing Furnace For Operation
Before attempting to put your furnace into operation for the
heating season, you should perform the following procedures
.
1. Open all warm air registers and make sure that all return air
grills are unobstructed.
2. If a humidifier is installed with your system, open the water
supply valve.
3. Set the thermostat to its lowest setting.
4. Turn on electric power to the furnace.
5. Open the oil supply valve.
6. Check all connections to ensure there are no leaks.
WARNING
If you do not follow these instructions exactly, a
fire or explosion may result causing property
damage, personal injury, or loss of life.

Lighting Your Furnace
1. This appliance is equipped with an ignition device which
automatically lights the burner. Do NOT try to light the
burner by hand.
2. After preparing the furnace for heating operation (See pre-
vious section) and checking for oil, proceed as follows.
3. For a heating/cooling system, set the thermostat to HEAT
and the fan to AUTO. Set the thermostat to the desired
room temperature and TURN ON the electrical power to
the furnace.
4. The burner should light and the system should be controlled
by the thermostat.
Turning Off Your Furnace
Follow these simple procedures to put your furnace into retire-
ment for the summer.
1. Set the thermostat to the lowest setting.
2. TURN OFF all electric power to the appliance.
3. Turn the oil supply OFF.
4. If applicable, TURN OFF water supply to humidifier.
5. If furnace blower will be necessary for cooling system, re-
member to turn electric power backON when needed for air
conditioning.
MAINTAINING YOUR UNIT
The life of your system depends on the care you give it. Proper
care assures good performance; lack of it can damage the unit.
Here are the things you should do, or have your dealer service
technician do for you.
NOTE: Before you start, TURN OFF all electrical power to
unit and turn thermostat to OFF.
CAUTION
This furnace is equipped with an interrupted type
electronic ignition system. DO NOT ATTEMPT TO
LIGHT WITH A MATCH.
DANGER!
HIGH VOLTAGE AT IGNITOR.
!
!
Filters
A filter is supplied with the furnace (except 58BGA). It is
NECESSARY THAT ALL FURNACES BE EQUIPPED
WITH A FILTER.
If a different type of filter is used, it must be an equivalent high
airflow capacity
.
Keeping Filters Clean
As a homeowner, this is your most important responsibility.A
dirty filter reduces the efficiency of your system, causes erratic
performance of controls, and could result in damage to the mo-
tor or heat exchanger.
1. Inspect filters at regular intervals depending upon dirt con-
ditions. For new homes, check filters every week for 4 con-
secutiveweeks. In all cases, inspect yourfiltersatleast every
3 to 4 weeks when the system is in constant operation. Re-
place or clean filter at least at the beginning of each season
(heating & cooling) and thereafter as needed.
2. If the permanent filter supplied with the unit becomes dirty,
it can be cleaned with cold water and soap.
Be sure that the filter is thoroughly dry before installing back
into the furnace.
Lubricating Motors
Direct drive motor and blower assemblies are factory lubri-
cated and normally do not require oiling. If oiling is required,
lubrication of the blower motor is to be performed only by a
qualified service agency.
WARNING
Never operate unit without a filter or with filter ac-
cess door removed. Failure to adhere to this warn-
ing could lead to a hazardous condition which
could lead to equipment damage and bodily harm.

Here is A Handy Checklist
If your furnace fails to operate properly, first check the follow-
ing. It may save you the cost of a service call:
1. Is your room thermostat set correctly? On heating/cooling
systems, the thermostat should be turned to HEAT or COOL
and the fan set to AUTO or CONT (continuous fan opera-
tion).
2. Are the power and oil supplies both ON?
3. Are the filters clean?
If the answer to these questions is YES and the furnace still
does not operate properly, call your authorized dealer for
service.
CAUTION
A furnace that is installed in an insulated space
must be kept free and clear of insulating materials.
After the furnace is installed, or whenever addi-
tional insulation is added, check that all combus-
tion air intakes are free and clear and that all
clearance dimensions are maintained. INSULAT-
ING MATERIALS MAY BE COMBUSTIBLE.
WARNING
Do not use this furnace if any part has been under
water. Immediately call a qualified service techni-
cian to inspect the furnace and to replace any part
of the control system and any oil control which
has been under water. Failure to comply with this
warning could lead to equipment failure, electrical
shock, and a hazardous condition which may lead
to bodily harm.
!
!
WARNING
The unit cabinet must have an uninterrupted or
unbroken electrical ground to minimize personal
injury if an electrical fault should occur. This may
consist of electrical wire or approved conduit
when installed in accordance with existing electri-
cal codes. Do not use oil piping as an electrical
ground. Failure to follow this warning could result
in an electrical shock, fire, or bodily harm.
WARNING
Return air must not be taken from the room in
which the appliance is installed. All duct connec-
tions to the furnace must be airtight to avoid a
“negative” pressure condition within the room. In-
correct ductwork termination and sealing will cre-
ate a hazardous condition which could lead to
bodily harm.
