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:

• 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. Immediately 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

for 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 . 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.

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:

FOR YOUR SAFETY

Do not store or use gasoline or other flam-

mable vapors and liquids in the vicinity of

this or any other appliance.

WARNING

FIRE, EXPLOSION, CARBON MONOXIDE POI-

SONING HAZARD

Failure to follow this warning could lead to

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 con-

taining gasoline!

CAUTION

FIRE AND UNIT OVERHEAT HAZARD

Failure to follow this caution may result in mi-

nor personal or property damage.

Never burn garbage or paper in the heating

system and never leave rags, paper, or any

flammable items around the unit.

CAUTION

FIRE AND EXPLOSION HAZARD

Failure to follow this caution may result in mi-

nor personal or property damage.

This furnace is equipped with a constant type

primary ignition system. DO NOT ATTEMPT

TO LIGHT WITH A MATCH.

•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 FILTERS:

Before attempting to start

your furnace, be sure the furnace air ﬁlters are clean

and in place. See “Performing Routine Maintenance”

section in this manual. Then proceed as follows:

STEPS FOR STARTING YOUR

FURNACE

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. Make sure blower access door is secured in place.

4. Set your room thermostat to the lowest temperature

setting. (See Fig. 5.)

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

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

7. Check all connections to ensure there are no leaks.

8. Set room thermostat to a temperature slightly above

room temperature. This will automatically signal

the furnace to start.

9. When the thermostat calls for heat, power from the

transformer energizes the fan control board. The fan

control energizes the ignition control. The ignition

control will automatically light the burner.

The electronic fan control automatically turns on

the blower after 60 sec. Fan on control is not adjust-

able. 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 a continuous ignition

control. If the main burner does not ignite within

30 sec from 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.

10. Set your thermostat to the temperature that satisﬁes

your comfort requirements. SUGGESTION: Set-

ting the thermostat back a few degrees and compen-

sating 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 “comfort level” are the most costly

degrees to obtain.

When room temperature drops below the tempera-

ture selected on the thermostat, the furnace will be

switched on automatically. When room temperature

reaches the degree selected on the 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 off, 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 the indoor air.

NOTE:

Constant low-speed blower operation can also

be achieved by turning on the constant blower rocker

switch located on top of unit. Regardless of room ther-

mostat setting, blower will run continuously in low

speed to provide constant air circulation. If constant

blower rocker switch is turned off, room thermostat

will control blower operation.

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 following procedures must be followed:

1. Set the thermostat to the lowest setting.

(See Fig. 8.)

2. Turn off all electrical power to the appliance.

(See Fig. 9.)

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

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

5. If furnace blower will be necessary for cooling sys-

tem, remember to turn electric power back on when

needed for air conditioning.

6. If the furnace is being shut down because of a mal-

function, call your dealer as soon as possible.

ALWAYS KEEP MAIN OIL VALVE TURNED OFF

IF BURNER IS SHUT DOWN FORAN EXTENDED

PERIOD OF TIME.

PERFORMING ROUTINE

MAINTENANCE

With proper maintenance and care, your furnace will

operate economically and dependably. Instructions for

basic maintenance follow. However, before beginning

maintenance, follow these safety precautions:

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 the furnace air ﬁlters be checked

every 3 or 4 weeks and cleaned or replaced as necessary.

The air ﬁlters are located in the blower compartment

installed in an internal ﬁlter rack which is provided as

standard equipment with furnace. (See Fig. 2.) To

4. Inspect the ﬁlter. If torn, replace it.

NOTE:

If ﬁlter that was shipped with furnace has

been replaced with an electronic air cleaner (EAC),

refer to the EAC Owner’s Manual for maintenance

information.

5. The ﬁlters shipped with the furnace are disposable.

If they are dirty, they must be replaced. If your fur-

nace air ﬁlters need to be replaced, be sure to use the

same size and type of ﬁlter that was originally sup-

plied. Use the furnace ﬁlter table and compare your

furnace size with the proper ﬁlter size.

FURNACE AIR FILTER TABLE

If you have replaced the factory-provided disposable

ﬁlters with permanent washable ﬁlters, they may be

cleaned if they are dirty. Wash ﬁlters in a sink, bathtub,

or outside with a garden hose. Always use cold tap

water. A mild liquid detergent may be used if neces-

sary. Spray water through ﬁlter in the opposite direc-

tion of airﬂow. Allow ﬁlter to dry.

6. Reinstall clean air ﬁlters by reversing procedure in

item 3 above.

7. Replace blower access door. (See Fig. 16.)

8. Turn on electrical supply to furnace.

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 secondary tube passage ways including

chimney — clean if necessary.

•Change oil ﬁlter.

•Change nozzle.

•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 FAILS 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 for 3

sec in order to reset the control.

•Check for obstructions around the vent termination.

If the furnace still fails to operate, call your service rep-

resentative. For your convenience, record the furnace
