IMPORTANT FACTS
SAFETY CONSIDERATIONS
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.
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.
To minimize the possibility of serious personal injury,
fire, furnace damage, or improper operation, carefully
follow these safety rules:
FORYOUR SAFETY
Do not store or use gasoline or other flam-
mable vapors and liquids in the vicinity of
this or any other appliance.
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.

WARNING
3
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!
• 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.
!
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.
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.
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:
NOTE:The qualified installer or agency must use only
factory-authorized replacement parts, kits, and acces-
sories when servicing this product.
!
CAUTION
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.
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.

ELECTRICAL SHOCK HAZARD HIGH VOLT-
AGE AT IGNITER.
7. Check all connections to ensure there are no leaks.
Severe electrical shock, personal injury, or
death will result.
8. Set room thermostat to a temperature slightly above
room temperature. This will automatically signal
the furnace to start.
• 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.
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.
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:
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.
STEPS FOR STARTING YOUR
FURNACE
1. Open all warm air registers and make sure that all
return-air grills are unobstructed.
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.
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.)
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.

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.

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.
• Check flue and secondary tube passage ways including
chimney — clean if necessary.
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.
• 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.
• Check for blocked return-air or supply-air grilles
throughout your home. Ensure they are open and
unobstructed.
• Inspect and clean the blower motor and wheel.
• Inspect and change or clean air filters if necessary.
If problem still exists, call your dealer for service.
IF FURNACE FAILS TO OPERATE:
• Inspect all supply- and return-air ducts for obstruc-
tions, air leaks, and insulation. Remedy any problem
when necessary.
Follow this checklist step by step, advancing to the next
step only if furnace fails to start.
• 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.
• 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?
• Inspect electrical wiring, connections, and compo-
nents for loose connections.
• Is valve in oil supply pipe in open position?
• Examine the physical support of the furnace. Support
should be sound with no cracks, sagging, gaps, etc.
around the base.
• 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 furnace for any obvious signs of deterioration.
• 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
product and serial numbers on page 2. Should you ever
require service, you will have ready access to the infor-
mation needed by your service representative.
