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.)

6. Open the oil supply valve. (See
Fig. 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
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 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-
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.
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.
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 thermo-
stat setting, blower will run contin-
uously 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 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.)
