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, fur-
nace damage, or improper opera-
tion,
carefully follow these
safety rules:
3
• 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 softener
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 re-
modeling be sure the combustion
air is fresh and uncontaminated. If
air with vapors of these com-
pounds 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 ser-
vice technician to inspect the fur-
nace and to replace any part of the
control system, electrical compo-
nents, and any oil control which
has been under water.
NOTE:
The qualified installer or
agency must use only factory-
authorized replacement parts, kits,
and accessories when servicing
this product.
The furnace burner control has a
safety device which must be man-
ually reset. If the furnace is left
unattended for an extended period
of time, have it checked periodi-
cally 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 person-
nel 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 per-
formed by trained service person-
nel. 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 man-
uals, be alert to the potential for
personal injury.
Understand the signal words —
DANGER, WARNING, and CAU-
TION. These words are used with
the safety-alert symbol. DANGER
identifies the most serious hazards
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
may

•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 Rou-
tine 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
5. Turn on electric power to the
furnace. (See Fig. 6.)
6
6. Open the oil supply valve. (See
Fig. 7.)
7
7. Check all connections to ensure
there are no leaks.
8. Set room thermostat to a tem-
perature slightly above room
temperature. This will auto-
matically signal the furnace to
start.
9. When the thermostat calls for
heat, power from the trans-
former energizes the fan control
board. The fan control energizes
the ignition control. The ignition
control will automatically light
the burner.
The electronic fan control auto-
matically 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 a con-
tinuous 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 con-
trol 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 tem-
perature that satisfies your com-
fort requirements.
SUGGESTION: Setting the ther-
mostat back a few degrees and
compensating for the difference
with warmer clothing can make a
big difference in your fuel con-
sumption 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 temperature selected
on the thermostat, the furnace
will be switched on automati-
cally. 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 selections, AUTO
and ON. When thermostat is set
to AUTO, the furnace blower
cycles on and off, controlled by
the thermostat. In ON mode,
the furnace blower runs contin-
uously. This keeps the tempera-
ture level in your home more
evenly balanced. It also contin-
uously filters the indoor air.
SHUTTING DOWN
YOUR FURNACE
Should you need to shut down your
furnace for service or mainte-
nance, you will need to turn the
furnace off. The following proce-
dures must be followed:
1. Set the thermostat to the lowest
setting. (See Fig. 8.)
8
2. Turn off all electrical power to
the appliance. (See Fig. 9.)
9
3. Close the oil supply valve.
(See Fig. 10.)
DANGER
ELECTRICAL SHOCK HAZ-
ARD HIGH VOLTAGE AT
IGNITER.
Severe electrical shock, per-
sonal injury, or death will
result.

4. If applicable, turn off water sup-
ply to humidifier.
5. If furnace blower will be neces-
sary for cooling system, remem-
ber to turn electric power back
on when needed for air condi-
tioning.
6. If the furnace is being shut down
because of a malfunction, 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

your furnace will operate economi-
cally and dependably. Instructions
for basic maintenance follow. How-
ever, before beginning maintenance,
follow these safety precautions:
11
12
FILTERING OUT
TROUBLE
Dirty air filters will cause a loss of
airflow in your duct system. When
excessive loss of airflow occurs,
the furnace may cycle on its safety
controls. If this condition is left
unattended, the furnace will even-
tually 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 pro-
vided as standard equipment with
furnace. (See Fig. 2.) To inspect,
clean, and or replace air filters, fol-
low these steps:
1. Turn off electrical supply to fur-
nace. (See Fig. 11.)
2. Remove blower access door in
rear of furnace. (See Fig. 13.)
Lift door up, then out using han-
dle on blower access door.
13
3. Remove air filters from furnace.
a. Remove filter resting in filter
rack at an angle in front of
blower first. Slide filter back
to clear filter rack ends then
lift up and out of filter rack
and blower compartment.
(See Fig. 14.)
14
b. Remove second filter lying
above blower. Slide filter
toward rear of furnace and
out of blower compartment.
(See Fig. 15.)

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 informa-
tion.
5. The filters shipped with the fur-
nace are disposable. If they are
dirty, they 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 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 necessary.
Spray water through filter in the
opposite direction 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 impor-
tant 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 following
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 vent piping inside struc-
ture for deterioration and vent termi-
nations 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 fil-
ters if necessary.
• Inspect all supply- and return-air
ducts for obstructions, air leaks, and
insulation. Remedy any problem
when necessary.
• Inspect the return-air duct connec-
tions 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, connec-
tions, 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.
