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:
FOR YOUR SAFETY
Do not store or use gasoline or other flammable
vapors and liquids in the
vicinity of this or any
other appliance.
Immediately call a qualified service technician 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 factoryauthorized replacement parts, kits,
and accessories 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 periodically for proper operation. This
precaution will prevent problems
associated with no heat, such as
frozen water pipes, etc.
SAFETY
CONSIDERATIONS
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 remodeling be sure the combustion
air is fresh and uncontaminated. 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.
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, WARNING, and CAUTION. These words are used with
the safety-alert symbol. DANGERost serious 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 would result in
4
minor personal injury or product
and property damage.
! WARNING
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.
! CAUTION
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:
! CAUTION
This furnace is equipped
with a constant type primary
ignition system. DO NOT
ATTEMPT TO LIGHT WITH A
MATCH.
4
! DANGER
HIGH VOLTAGE AT IGNITOR.
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 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
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 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 adjustable. 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 comfor 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 “comfort level” are
the most costly degrees to obtain.
5
When room temperature drops
below the temperature 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 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 continuously. This keeps the temperature 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 thermostat 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.)
®
8
2. Turn off all electrical power to
the appliance. (See Fig. 9.)
! WARNING
! CAUTION
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.
Never operate your furnace
without the air filters in place.
Doing so may damage the
furnace blower motor. An
accumulation of dust and lint
on internal parts of your
furnace can cause a loss of
efficiency.
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 inspect,
clean, and or replace air filters, follow these steps:

4. If applicable, turn off water supply to humidifier.
5. If furnace blower will be necessary for cooling system, remember to turn electric power back
on when needed for air conditioning.
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
MAINTENANCE
With proper maintenance and care,
your furnace will operate economically and dependably. Instructions
for basic maintenance follow. However, before beginning maintenance,

! CAUTION
Although special care has
been taken to minimize 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 furnace 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.
