FURNACE OPERATION INFORMATION
During the heating season, the operation of the furnace is
fully automatic.
To Start The Furnace:
1. First read these instructions and safety notices
thoroughly.
2. Set the thermostat to the lowest setting.
3. Ensure that all supply air registers and return air grilles
are open.
4. Turn off the electric power to the furnace.
5. Remove the burner access door.
6. Ensure that the appliance manual shutoff valve is in the
"ON" position. The valve handle is normally in-line
with the gas pipe and valve body when it is in the "ON"
position perpendicular to the gas piping and valve
body when it is in the "OFF" position.
7. Wait 5 minutes to clear out any gas. If, after this time
you smell gas, STOP. Turn the appliance manual shutoff
valve to the "OFF" position. If burning propane or
other LP gas, smell for gas near the floor since propane
and butane are both heavier than air. If after this time
you do not smell gas, continue to the next step.
8. Gas valve: Ensure that the Gas Valve Control is in the
"ON" position, see Figure 3 at right.
9. Replace the burner access door, ensuring that it is
properly in place.
10. Restore the electric power to the furnace.
11. Adjust the thermostat to the desired setting. If the
thermostat also controls an air conditioning system,
ensure that the thermostat system switch is in the
"HEAT" or "AUTO" mode.
If this is the first time that the furnace has undergone a trial
ignition since installation, or if there has been work done
on the gas lines, the furnace might not light because of air
trapped in the gas supply line.
Simply turn the thermostat down to its lowest setting, wait
five minutes, then adjust the thermostat to the desired
setting. If the problem persists, proceed to the Furnace Shut
Down Procedure and call your installer, service agency or
gas supplier.
If you intend to be away from home for lengthy periods of
time during the non-heating season, it is advisable to follow
the furnace shut down procedure.
WARNING
NEVER USE TOOLS TO TURN A MANUAL GAS CONTROL
HANDLE. IF THE CONTROL HANDLE WILL NOT TURN BY
HAND, DO NOT ATTEMPT TO FORCE IT. DOING SO
COULD RESULT IN FIRE OR EXPLOSION RESULTING IN
SERIOUS PERSONAL INJURY OR DEATH, OR PROPERTY
DAMAGE. CALL A QUALIFIED INSTALLATION
CONTRACTOR, SERVICE AGENCY OR GAS SUPPLIER.
Furnace Shutdown Procedure
1. Set the thermostat to its lowest setting.
2. Shut off electric power to the furnace.
3. Turn the appliance manual shutoff valve to the "OFF"
position.
4. Remove the burner access door, move the manual gas
control switch to the "OFF" position, then reinstall the
burner access door.
If you intend to be away from home for lengthy periods of
time during the nonheating season, it is advisable to follow
the furnace shutdown procedure.
