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:
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
withchlorineorfluorine.Thesecompoundsarepresent
in many products around the home, such as: water soft-
ener salts, laundry bleaches, detergents, adhesives,
paints, varnishes, paint strippers, waxes, and plastics.
Makesurethecombustionairforyourfurnacedoesnot
contain any of these compounds. During remodeling
be sure the combustion air is fresh and uncontami-
nated. 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 agencymustuse 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
would result in
minor personal injury or product and property damage.
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:

• If a suspected malfunction occurs with your oil control
system, such as the burner not lighting when it should,
refer to the “Shutting DownYour 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
5. Turn on electric power to furnace. (See Fig. 6.)
6. Open oil supply valve. (See Fig. 7.)
67
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
transformerenergizesthefancontrolboard.Thefan
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 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
switchedonautomatically.When roomtemperature
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 continuously. This keeps the tempera-
ture level in your home more evenly balanced. It
also continuously 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:
DANGER
HIGH VOLTAGE AT IGNITOR. Severe electrical
shock, personal injury, or death could result.

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:
11
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.
Theair filterisinstalled inan external filterrack 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.
