IMPORTANT FACTS

Your furnace must have adequate airflow for efficient
combustion and safe ventilation. Do not enclose it in

an airtight room or "seal" it behind solid doors.
To minimize the possibility of serious personal injury,

fire, furnace damage, or improper operation, carefully
follow these safety rules:

Donot store or use gasoline or other flam-
mable vapors and liquids in the vicinity of

this or any other appliance,

• Do not cover the furnace, store trash or debris near
it, or in any way block the flow of fresh air to the unit.

° Combustion air must be clean and not contaminated
with chlorine or fluorine. These compounds are present

in many products around the home, such as: water soft-
ener salts, laundry bleaches, detergents, adhesives,

paints, varnishes, paint strippers, waxes, and plastics.
Make sure the combustion air for your furnace does

not contain any of these compounds. During remodel-
ing be sure the combustion air is fresh and uncontam-

inated. If air with vapors of these compounds is burned
in your furnace, the heat exchangers and metal vent
system may deteriorate.

NOTE: Do not use this furnace if any part has been
under water, hmnediately call a qualified service tech-

nician to inspect the furnace and to replace any part of
the control system, electrical components, and any oil

control which has been under water.
NOTE: The qualified installer or agency must use only

factory-authorized replacement parts, kits, and acces-
sories when servicing this product.

The furnace burner control has a safety device which
must be manually reset. If the furnace is left unattended

fbr an extended period of time, have it checked period-
ically for proper operation. This precaution will prevent

problems associated with no heat, such as frozen water
pipes, etc.

SAFETY CONSIDERATIONS

Installing and servicing of heating equipment can be
hazardous due to oil and electrical components. Only
trained and qualified personnel should install, repair,

or service heating equipment.
Untrained personnel can perform basic maintenance

functions such as cleaning and replacing air filters. All
other operations must be performed by trained service

personnel. Observe safety precautions in this manual,
on tags, and on labels attached to the furnace and other

safety precautions that may apply.
Recognize safety information. This is the safety-alert

symbol AX. When you see this symbol on the furnace
and in instructions or manuals, be alert to the potential

for personal injury.
Understand the signal words -- DANGER, WARN-

ING, and CAUTION. These words are used with the
safety-alert symbol. DANGER identifies the most seri-
ous 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 per-
sonal injury or product and property damage. NOTE is

used to highlight suggestions which will result in
enhanced installation, reliability or operation.

FIRE, EXPLOSION, CARBON MONOXIDE
POISONING HAZARD

sooting, fire, explosion, and/or severe bodily

harm.
For use with grade 2 Fuel Oil maximum. Do

not use Gasoline, Crankcase Oil, or any Oil
containing Gasoline!

FIRE AND UNIT OVERHEAT HAZARD
Failure to follow this warning could result in
unit damage.

Never burn garbage or paper in the heating
system and never leave rags, paper, or any

flammable items around the unit.

STARTING YOUR FURNACE

This appliance is equipped with an ignition device which
automatically lights the burner each time the thermostat
starts your furnace. Follow these important safeguards:

EXPLOSION HAZARD
Failure to follow this warning could result in

property damage or personal injury or death.
This furnace is equipped with a constant type

primary ignition system. DO NOT ATTEMPT
TO LIGHT WITH A MATCH.

T_ IDI_4_[_ ::1-']

ELECTRICAL SHOCK HAZARD HIGH VOLT-

AGE AT IGNITER.

Severe electrical shock, personal injury, or
death could result.

• If a suspected malfunction occurs with your oil control
system, such as the burner not lighting when it should,

refer to the "Shutting Down Your Furnace" section and
call your dealer as soon as possible.

CHECK AIR FILTER: Before attempting to start
your furnace, be sure the furnace air filter is clean and

in place. See" Performing Routine Maintenance" sec-
tion in this manual. Then proceed as follows:

STEPS FOR STARTING YOUR

FURNACE

I. 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
water supply valve.

3. Make sure blower access door is secured in place.

4. Set your room thermostat to lowest temperature set-
ting. (See Fig. 5.)

f

5. Turn on electric power to furnace. (See Fig. 6.)

6. Open oil supply valve. (See Fig. 7.)

.

8.

10.

6 7

Check all connections to ensure there are no leaks.
Set room thermostat to a temperature slightly above

room temperature. This will automatically signal
the furnace to start.

When the thermostat calls for heat, power from the
transformer energizes the fan control board. The

fan control energizes the ignition control. The igni-
tion control will automatically light the burner.

The electronic fan control automatically turns on
the blower. The air moved over the heat exchanger

by the blower is warmed and passes through the
ducts to the room registers.

This unit is equipped with continuous ignition
control. If the main burner does not ignite within
30 sec Dom the call for heat, the control will lock

out. The red button on top of the control must be
depressed for 3 sec in order to reset the control.

The control CANNOT be reset from the room
thermostat.

Set your thermostat to the temperature that satisfies
your comfort requirements.

SUGGESTION: Setting the thermostat back a few
degrees and compensating for the difference with

warmer clothing can make a big difference in your
fuel consumption on extremely cold days. The few

degrees at the top of your thermostat "comfbrt
level" are the most costly degrees to obtain.

When room temperature drops below temperature
selected on the thermostat, the furnace will be

switched on automatically. When room tempera-
ture reaches the degree selected on thermostat, the
furnace will be switched off automatically.

Some thermostats have a FAN mode with 2 selec-
tions, AUTO and ON. When thermostat is set to

AUTO, the furnace blower cycles on and oft, con-
trolled by the thermostat. In ON mode, the furnace

blower runs continuously. This keeps the tempera-
ture level in your home more evenly balanced. It

also continuously filters indoor air.

SHUTTING DOWN YOUR FURNACE

Should you need to shut down your furnace for service
or maintenance, you will need to turn the furnace off.

The tollowing procedures must be followed:

1. Set thermostat to lowest setting.
(See Fig. 8.)

f

2. Turn off all electrical power to furnace.
(See Fig. 9.)

3. Close oil supply valve. (See Fig. 10.)

10

4. If applicable, turn off water supply to humidifier.

5. If furnace blower will be necessary tbr cooling sys-
tem, remember to turn electric power back on when

needed tor air conditioning.

6. If furnace is being shut down because of a malfunc-
tion, call your dealer as soon as possible.

ALWAYS KEEP MAIN OIL VALVE TURNED OFF
IF BURNER IS SHUT DOWN FORAN EXTENDED
PERIOD OF TIME.

ELECTRICAL SHOCK HAZARD
Failure to take this warning could result in

personal injury or death.
Turn off all electrical power to furnace before

performing any maintenance or service on
unit.

CUT HAZARD
Failure to follow this caution may result in per-

sonal injury.
Although special care has been taken to mini-
mize sharp edges, be extremely careful when
handling parts or reaching into the furnace.

FILTERING OUT TROUBLE

Dirty air filters will cause a loss of airflow in your duct
system. When excessive loss of airflow occurs, the fur-

nace may cycle on its safety controls. If this condition
is left unattended, the furnace will eventually lock out.

It is recommended that furnace air filters be checked
every 3 or 4 weeks and cleaned or replaced as necessary.

UNIT DAMAGE HAZARD
Failure to follow this caution may result in re-

duced unit component life.
Never operate your furnace without the air fil-

ters in place. Doing so may damage the fur-

nace blower motor. An accumulation of dust
and lint on internal parts of your furnace can

cause a loss of efficiency.

PERFORMING ROUTINE

MAINTENANCE

With proper maintenance and care, your furnace will

operate economically and dependably. Instructions tor
basic maintenance tollow. However, betore beginning

maintenance, tollow these safety precautions:

The air filter is installed in an external filter rack which
is provided as standard equipment with furnace. To

inspect, clean, and/or replace air filter, follow these
steps:

1. Turn off electrical supply to furnace. (See Fig. 11.)

2. Remove filter from external filter rack.

3. Inspect filter. If torn, replace it.

NOTE: If filter has been replaced with an electronic
air cleaner (EAC), refer to EAC Owner's Manual for
maintenance information.

4. If filter is dirty, it must be replaced. If your furnace
air filter needs to be replaced, be sure to use the same

size and type of filter that was originally supplied.

A CHECK-UP CHECKLIST

Your furnace represents an important investment in
your family's comfort and your home's value. To keep

it performing properly and as a preventative to future
problems, have a trained service specialist give your

furnace a professional check-up annually. The fol-
lowing checklist can be used as a guideline to proper

service:

• Check flue and seconda U tube passage ways including
chimney -- clean if necessary.

• Change oil filter.

• Change nozzle.

• Check and adjust combustion and draft.

• Inspect all vent piping inside structure for deterioration
and vent terminations outside the structure for blockage.

• Check oil pipes leading to and inside of your furnace
for leaks.

• Inspect and clean the blower motor and wheel.

• Inspect and change or clean air filter if necessary.

• Inspect all supply- and return-air ducts fl)r obstruc-
tions, air leaks, and insulation. Remedy any problem

when necessau.

• Inspect the return-air duct connections at the furnace to
ensure it is physically sound, sealed to the furnace
casing, and terminates outside the space containing the

furnace.
° Inspect electrical wiring, connections, and compo-

nents fbr loose connections.
° Examine the physical support of the furnace. Support

should be sound with no cracks, sagging, gaps, etc.
around the base.

° Check furnace for any obvious signs of deterioration.

BEFORE YOU REQUEST

A SERVICE CALL

If your furnace is not operating or not performing
properly, you may save the expense of a service call

by checking a few things yourself before calling for
service.

FOR INSUFFICIENT AIRFLOW:

• Check for dirty air filters.

• Check for blocked return-air or supply-air grilles
throughout your home. Ensure they are open and

unobstructed.
If problem still exists, call your dealer for service.

IF FURNACE FALLS TO OPERATE:
Follow this checklist step by step, advancing to the next

step only if furnace fails to start.

• Check thermostat for proper temperature. Is thermo-
stat set above room temperature?

• Is thermostat set on HEAT'?

• Check fuses and circuit breakers. Is electrical supply

on'?

• Is valve in oil supply pipe in open position'?

• Is the ignition control on the burner not in lockout'? The
red button on top of the control must be depressed fl)r 3

sec in order to reset the control.

• Check for obstructions around the vent termination.

If furnace still fails to operate, call your service represen-
tative. For your convenience, record furnace product and
