HEATER PARTS REMOVAL AND INSTALLATION

Most heater parts can be removed by simply identifying any attached wiring. Then DISCONNECT the ob- vious mounting parts.

1.Flame sensor: DISCONNECT the wire connector. UNSCREW the flame sensor out of its mounting bracket.

2.Gas Solenoid valve coil: UN- SNAP either the plastic cap, or the metal clip on the gas valve, and SLIDE the housing and coil off the valve stem and body. Do

not energize the coil when it is removed, as the coil may be- come damaged due to exces- sive current flow.

3.Regulator and gas solenoid valve(s):Thegasregulatorandso- lenoid valve(s) are directional and mustbeconnectedasindicatedby the markings near the port open- ings. Make sure gas is shut off and purged from the system before re- movingparts.

Note: When installing a liquid gas solenoid valve on LP models, do not over tighten the connection into the inlet side, as the inlet orifice may become partially blocked.

b. Disconnect gas solenoid valve coils. Be sure to mark which one goeswhere.

c. Lift pipe (with orifice, solenoid valve and other parts attached), straight up and remove from fan heater housing. Orifice and other parts can now be removed from pipe train, if desired.

5.Reassemble: To reassemble parts,reversethedisassemblypro- cedureandcheckthefollowing:

b. Use a dependable brand of high temperature pipe caulking compound when assembling gas connections. Apply only a light coating onto male threaded end of fittings.

c. Solenoid valves and gas regula- tors are directional and must be properly installed. Do not attempt to connect gas solenoid valve by applying force to the valve core stem as it may ruin the unit.

d. Make sure all electrical wires are properlyconnected.Refertowiring diagrams.
