FOR YOUR SAFETY READ BEFORE LIGHTING
CAUTION
Shock and burn hazard.
G32V units are equipped with the SureLight igni-
tion system. Do not attempt to light manually.
WARNING
Do not use this furnace if any part has been under-
water. Inspect the furnace and 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 main-
tenance, turn the electrical power to unit OFF at
disconnect switch.
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.
Use only your hand to turn the gas control switch. Never
use tools. If the switch will not turn by hand, do not try to re-
pair it, call a qualified service technician. Force or at-
tempted repair may result in a fire or explosion.
G32V units are equipped with the SureLight ignition system.
DO NOT attempt to manually light burners on this furnace.
Each time thermostat calls for heat, burners will be automati-
cally lit. The ignitor does not get hot when there is no call for
heat on units with SureLight ignition system.
