PROHEAT M-SERIES G-II PCM SERVICE MANUAL

Test Procedure – Air Compressor pressure (Rotary Vane Compressor models):

Ensure fuel nozzle is clean (see page 4-7)and the air compressor filter is

clean (see page 4-9) before proceeding with air compressor pressure check.

h) Thread in Pressure Gauge Adapter hand tight as shown in Figure 4-10.

i) I

nstall pressure Relief Valve & Pressure Gauge on to Pressure Gauge Adapter.

j) Orient Burner Head similar to assembled on heater.

k) Connect Power Harness and Remote Switch to the G-II PCM.

l) Switch the PROHEAT on and observe the air pressure:

o) Connect the Power, Dual Mode Temperature Sensor and Coolant Pump

electrical connections to the heater Burner Had and reconnect the fuel line.
