a gas control knob or gas control lever. Use only your hand
to push the lever or turn the gas control knob, Never use
tools. If the the lever will not move or the knob will not push

Placing the furnace into operation:
G61MPV units are equipped with an automatic ignition sys-
tem. Do not attempt to manually light burners on this fur-
nace, Each time the thermostat calls for heat, the burners
will automatically light. The ignitor does not get hot when
there is no call for heat on units with this ignition system.
AkCAUTION
Priming Condensate Trap
The condensate trap should be primed with water prior to
start-up to ensure proper condensate drainage. Either pour
10 fi, oz. (300 ml) of water into the trap, or follow these steps
to prime the trap:
1 - Follow the lighting instructions to place the unit into op-
eration,
2 - Set the thermostat to initiate a heating demand,
3 - Allow the burners to fire for approximately 3 minutes,
4- Adjust the thermostat to deactivate the heating de-
mand,
5 - Wait for the combustion air inducer to stop, Set the
thermostat to initiate a heating demand and again al-
low the burners to fire for approximately 3 minutes,
6- Adjust the thermostat to deactivate the heating de-
mand and again wait for the combustion air inducer to
stop. At this point, the trap should be primed with suffi-
cient water to ensure proper condensate drain opera-
tion,
BEFORE LIGHTING the unit, smell all around the furnace
area for gas, Be sure to smell next to the floor because
some gas is heavier than air and will settle on the floor.
