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 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. 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 clue 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, WARNING,

and CAUTION. These words are used with the safety-

alert symbol. DANGER identifies the most serious haz-

ards which will result in severe personal injury or death.

WARNING signifies hazards which could result in per-

sonal injury or death. CAUTION is used to identify

unsafe practices which would result in minor personal

injury or product and property damage.

For use with grade 2 Fuel Oil maximum. Do

not use Gasoline, Crankcase Oil, or any Oil

containing Gasoline! Failure to follow this

warning could lead to sooting, fire, explosion,

and/or severe bodily harm.

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:

This furnace is equipped with a constant type

primary ignition system. DO NOT ATTEMPT

TO LIGHT WITH A MATCH.

HIGH VOLTAGE AT IGNITOR. Severe electrical

shock, personal injury, or death could result.

• Ifa 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

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

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.)

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

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

6 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.

.When the thermostat calls for heat, power from the

transformer energizes the fan control board. The

Pan control energizes the ignition control. The igni-

tion control will automatically light the burner.

The electronic Ihn 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 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 temperature

selected on the thermostat, the furnace will be

switched on automatically. When room temperature

reaches the degree selected on thermostat, the fur-

nace 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 contilmously. This keeps the tempera-

ture level in your home more evenly balanced. It

also contilmously filters indoor air.

NOTE: Constant low-speed blower operation can also

be achieved by turning on the constant blower rocker

switch located on side of control box. Regardless of

room thermostat setting, blower will run continuously

in low speed to provide constant air circulation. If con-

stant blower rocker switch is turned off, room thermo-

stat 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 thermostat to lowest setting.

(See Fig. 8.)

2. Turn off all electrical power to furnace.

(See Fig. 9.)

3. Close 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 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 FOR AN 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 begilming

maintenance, follow these safety precautions:

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.

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.

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.

Use furnace filter table for filter size and filter rack

flange dimensions for return air duct.

FURNACE AIR FILTERTABLE

Turn off all electrical power to furnace before

performing any maintenance or service on

unit. Failure to take this precaution may result

in personal injury due to electrical shock.

OPENING FILTER

SIZE SIZE FILTER

(IN.) (IN.) TYPE

15 X 24 16 X 24 25 X 1 Disposable

17 X 30 18 X 30 X 1 Disposable

If you have replaced a disposable filter with a perma-

nent washable filter, it may be cleaned if it is dirty.

Wash filter in a sink, bathtub, or outside with a garden

hose. Always use cold tap water. A mild liquid deter-

gent may be used if necessary. Spray water through

filter in the opposite direction of airflow. Allow filter

to dry.

5. Re-install clean air filter.

6. Turn on electrical supply to furnace.

ACHECK-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 and adjust combustion and draft.

• Inspect all veto 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 for obstruc-

tions, air leaks, and insulation. Remedy any problem

when necessary.

• 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, colmections, and components

for 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 FAILS TO OPERATE:

Follow this checklist step by step, advancing to the next

step only if furnace Pailsto start.

• Check thermostat for proper temperature. Is thermostat

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 furnace still Pails to operate, call your service represen-

tative. For your convenience, record furnace product and

serial numbers on page 2. Should you ever require

service, you will have ready access to the reformation

needed by your service representative.
