Unit Start−Up
FOR YOUR SAFETY READ BEFORE LIGHTING
WARNING
Do not use this furnace if any part has been underwa-
ter. 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.
CAUTION
Before attempting to perform any service or mainte-
nance, turn the electrical power to unit OFF at dis-
connect switch.
WARNING
During blower operation, the ECM motor emits ener-
gy that may interfere with pacemaker operation. In-
terference is reduced by both the sheet metal cabinet
and distance.
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 G60UHV(X) unit may be equipped
with either a gas control knob or gas control switch. Use
only your hand to move the control switch or to turn the gas
control knob. Never use tools. If the knob will not turn or if
the control switch will not move by hand, do not try to repair
it. Call a licensed professional service technician (or equiv-
alent). Force or attempted repair may result in a fire or ex-
plosion.
Placing the furnace into operation:
G60UHV(X) 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 burn-
ers will automatically light. The ignitor does not get hot
when there is no call for heat on units with an automatic
ignition system.
WARNING
If you do not follow these instructions exactly, a fire
or explosion may result causing property damage,
personal injury or death.
