CHECK AIR FILTER: Before  
attempting to start your furnace, be  
sure the furnace air filter is clean  
and in place. See “Performing Rou-  
tine Maintenance” section in this  
manual. Then proceed as follows:  
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 the ther-  
mostat, the furnace will be  
switched off automatically.  
STEPS FOR STARTING  
YOUR FURNACE  
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 continu-  
ously. This keeps the tempera-  
ture level in your home more  
evenly balanced. It also contin-  
uously filters indoor air.

1. Open all warm air registers and  
make sure that all return-air  
grills are unobstructed.  
7. Check all connections to ensure  
there are no leaks.  
2. If a humidifier is installed with  
your system, open water supply  
valve.  
8. Set room thermostat to a tem-  
perature slightly above room  
temperature. This will auto-  
matically signal the furnace to  
start.  
3. Make sure blower access door is  
secured in place.

continuously in low speed to pro-

turned off, room thermostat will  
control blower operation.  
The electronic fan control auto-  
matically 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.  
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:  
5
5. Turn on electric power to  
furnace. (See Fig. 6.)  
This unit is equipped with 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  
control must be depressed for 3  
sec in order to reset the control.  
The control CANNOT be reset  
from the room thermostat.  
1. Set thermostat to lowest setting.  
(See Fig. 8.)  
®
10. Set your thermostat to the tem-  
perature that satisfies your com-  
for requirements. SUGGES-  
TION: Setting the thermostat  
back a few degrees and compen-  
sating for the difference with  
warmer clothing can make a big  
difference in your fuel consump-  
tion on extremely cold days. The  
few degrees at the top of your  
thermostat “comfort level” are  
the most costly degrees to obtain.

To inspect, clean, and/or replace air  
filter, follow these steps:  
2. Turn off all electrical power to  
the furnace. (See Fig. 9.)  
!
WARNING  
Turn off all electrical power to  
furnace before performing  
any maintenance or service  
on unit. Failure to take this  
precaution may result in per-  
sonal injury due to electrical  
shock.  
1. Turn off electrical supply to fur-  
nace. (See Fig. 11.)  
2. Remove filter from external fil-  
ter rack.  
3. Inspect filter. If torn, replace it.  
NOTE: If filter has been replaced  
with an electronic air cleaner  
(EAC), refer to the EAC Owner’s  
Manual for maintenance informa-  
tion.  
9
3. Close oil supply valve.  
(See Fig. 10).  
5. If filter is dirty, it must be re-  
placed. If your furnace air filter  
needs to be replaced, be sure to  
use the same size and type of fil-  
ter that was originally supplied.  
Use furnace filter table for filter  
size and filter rack flange dimen-  
sions for return air duct.

If you have replaced a disposable  
filter with a permanent 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  
detergent may be used if necessary.  
Spray water through filter in the  
opposite direction of airflow.  
Allow filter to dry.  
FILTERING OUT  
TROUBLE  
4. If applicable, turn off water sup-  
ply to humidifier.  
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 furnace air filters be checked  
every 3 or 4 weeks and cleaned or  
replaced as necessary.  
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 furnace is being shut down be-  
cause of a malfunction, call your  
dealer as soon as possible.  
6. Re-install clean air filter.  
7. Turn on electrical supply to  
furnace.  
ALWAYS KEEP MAIN OIL  
VALVE TURNED OFF IF  
BURNER IS SHUT DOWN FOR  
AN EXTENDED PERIOD OF  
TIME.  
!
CAUTION  
A CHECK-UP  
CHECKLIST  
Never operate your furnace  
without the air filters in place.  
Doing so may damage the  
furnace blower motor. An ac-  
cumulation of dust and lint  
on internal parts of your fur-  
nace can cause a loss of effi-  
ciency.  
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:  
PERFORMING  
ROUTINE  
MAINTENANCE  
With proper maintenance and care,  
your furnace will operate economi-  
cally and dependably. Instructions  
for basic maintenance follow. How-  
ever, before beginning maintenance,  
follow these safety precautions:  
The air filter is installed in an ex-  
ternal filter rack which is provided  
a standard equipment with furnace.

OPERATE:  
Follow this checklist step by step,  
advancing to the next step only if  
furnace fails to start.  
• Check thermostat for proper tem-  
perature. Is thermostat set above  
room temperature?  
• Is thermostat set on HEAT?  
• Check fuses and circuit breakers.  
Is electrical supply on?  
• 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.  
BEFOREYOU REQUEST  
A SERVICE CALL  
• Check oil pipes leading to and  
inside of your furnace for leaks.  
• Is valve in oil supply pipe in open  
position?  
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.  
• Inspect and clean the blower motor  
and wheel.  
• Inspect and change or clean air fil-  
ter 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 fur-  
nace casing, and terminates outside  
the space containing the furnace.  
• Is the ignition control on the burn-  
er 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 fails to operate, call  
your service representative. For your  
convenience, record furnace product  
and serial numbers on page 2.  
Should you ever require service, you  
will have ready access to the infor-  
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 mation needed by your service rep-  
dealer for service.  
• Inspect electrical wiring, connec-  
resentative.
