Start-Up
For Your Safety, Read Before Operating
Do not use this furnace if any part has been under
water. Immediately call a licensed professional service
technician (or equivalent) to inspect the furnace and
to replace any part of the control system and any gas
control which has been under water.
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.
WARNING
Before attempting to perform any service or
maintenance, turn the electrical power to unit OFF at
disconnect switch.
CAUTION
During blower operation, the ECM motor emits
energy that may interfere with pacemaker operation.
Interference is reduced by both the sheet metal cabinet
and distance.
WARNING
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 this unit is equipped with a gas control
switch. Use only your hand to move the switch. Never use
tools. If the switch will not turn or if the control switch will
not move by hand, do not try to repair it.
Placing the Furnace into Operation
These units are equipped with an automatic ignition
system. Do not attempt to manually light burners on these
furnaces. Each time the thermostat calls for heat, the

ignition system.
If you do not follow these instructions exactly, a fire
or explosion may result causing property damage,
personal injury, or loss of life.
