CE OPERATION INFORMA
TION
During the heating season, the operation of the furnace is fully automatic.
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 grills are open.
4.
Turn of
f the electric power to the furnace.
5.
Remove the burner access door.
6.
Ensure that the furnace manual shut-off 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.
Turn the manual gas valve switch to the “OFF” position.

8.
Wait 5 minutes to clear out any gas. If, after this time you smell gas, ST
OP . T
urn the appliance manual
shut-off valve to the “OFF” position. If burning LP
gas, smell for gas near the fl
oor since propane and
butane are both heavier than air. If after this time you do not smell gas, continue to the next step.
9.
Turn the manual gas valve switch to the “ON” position.
10. Replace the burner access door
, ensuring that it is properly in place.
11.
Restore the electric power to the furnace.
12. 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 “AUT
O” mode.
If this is the fi
rst 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 5 minutes, then adjust the thermostat to the desired
setting. If the problem persists, proceed to
“Furnace Shut-Down Procedure”
and call your Installer, service
agency or gas supplier.
