Priming Condensate Trap

CAUTION

Before attempting to perform any service or mainte- nance, turn the electrical power to unit OFF at dis- connect switch.

The condensate trap should be primed with water prior to start−up to ensure proper condensate drainage. Either pour 10 fl. 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 fur- nace area for gas. Be sure to smell next to the floor be- cause some gas is heavier than air and will settle on the floor.

The gas valve on the G61MP will be be equipped with a gas control switch (lever). Use only your hand to move the switch. Never use tools. If the the switch will not move by hand, do not try to repair it. Force or attempted repair may result in a fire or explosion.

Placing the furnace into operation:

G61MP units are equipped with an automatic ignition system. Do not attempt to manually light burners on this furnace. 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.

WARNING

If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or death.

1 − STOP! Read the safety information at the beginning of this section.

2 − Set the thermostat to the lowest setting.

3 − Turn off all electrical power to the unit.

4 − This furnace is equipped with an ignition device which automatically lights the burners. Do not try to light the burners by hand.

5 − Remove the upper access panel.

6 − White Rodgers 36E Gas Valve − Move gas valve switch to OFF. See figure 55 for the White Rodgers 36E valve.
