DANGER
Danger of explosion.
There are circumstances in which odorant used with
LP/propane gas can lose its scent. In case of a leak,
LP/propane gas will settle close to the floor and may
be difficult to smell. An LP/propane leak detector
should be installed in all LP applications.
Do not attempt to bleed the gas lines of air. Call your
local gas provider.
Start−Up & Operation Information
WARNING
If you do not follow these instructions exactly, a fire
or explosion may result causing property damage,
personal injury or death.
BEFORE LIGHTING smell all around the appliance area
for gas. Be sure to smell next to the floor because some gas
is heavier than air and will settle on the floor.
The gas valve on the EL280DF is equipped with a gas con-
trol switch. Use only your hand to move the gas control
switch. Never use tools. If the switch will not move by
hand, do not try to repair it. Call a licensed professional
service technician (or equivalent). Force or attempted re-
pair may result in a fire or explosion.
Placing the EL280DF furnace into operation:
EL280DF units are equipped with a SureLight
®
ignition
system. Do not attempt to manually light burners on these
furnaces. Each time the thermostat calls for heat, the burn-
ers will automatically light. The ignitor does not get hot
when there is no call for heat on units with the SureLight
®
ignition system.

1 − STOP! Read the safety information at the beginning of
this section.
2 − Set the thermostat to the lowest setting.

Turning Off Gas to the Unit
WARNING
If overheating occurs or if gas supply fails to shut off,
shut off the manual gas valve to the appliance before
shutting off electrical supply.
1 − Set the thermostat to the lowest setting.
2 − Turn off all electrical power to the unit if service is to be
performed.

the number of heating cycles. Damage to the unit
may occur that is not covered by the warranty.
