Prime Condensate Trap With Water; Purge Gas Lines; Sequence Of Operation - Payne PG9MAA Installation Manual

Fig. 60—Inducer Housing Drain Cap
Before operating furnace, check flame rollout manual reset switch for continuity. If necessary, press button to reset switch.
PROCEDURE 2—PRIME CONDENSATE TRAP WITH WATER
CAUTION: UNIT MAY NOT OPERATE
Failure to follow this caution may result in intermittent unit operation.
Condensate trap must be PRIMED or proper draining may not occur. The condensate trap has 2 internal chambers which can ONLY
be primed by pouring water into the inducer drain side of condensate trap.
1. Remove upper inducer housing drain connection cap. (See Fig. 60.)
2. Connect field-supplied 1/2-in. ID tube to upper inducer housing drain connection.
3. Insert field-supplied funnel into tube.
4. Pour 1 quart of water into funnel/tube. Water should run through inducer housing, overfill condensate trap, and flow into open field drain.
(See Fig. 61.)
5. Remove funnel and tube from inducer housing and replace drain connection cap and clamp.
PROCEDURE 3—PURGE GAS LINES
WARNING: FIRE AND EXPLOSION HAZARD
Failure to follow this warning could result in a fire, explosion, personal injury, or death.
Never purge a gas line into a combustion chamber. Never test for gas leaks with an open flame. Use a commercially available soap
solution made specifically for the detection of leaks to check all connections.
If not previously done, purge lines after all connections have been made and check for leaks.
PROCEDURE 4—SEQUENCE OF OPERATION
CAUTION: FURNACE MAY NOT OPERATE
Failure to follow this caution may result in furnace operation stopping and water pipes freezing during cold weather.
Furnace control must be grounded for proper operation, or control will lock out. Control is grounded through green/yellow wire routed
to gas valve and burner box screw.
Using schematic diagram, follow sequence of operation through different modes. (See Fig. 34.) Read and follow wiring diagram carefully.
