CAUTION

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

CONNECTING OPTIONAL WALL SWITCH OR THERMOSTAT

1.Use 18 awg, two-wire cable, 15 feet maximum length.

2.At one end of the cable, connect both wires to the wall switch or thermostat. At the other end, connect one wire to TP/TH and one wire to TH, or connect the wall switch/thermostat to the two male (0.25") terminals on the left side of the unit. The color of the wires does not matter.

CHECKING SYSTEM OPERATION

The millivolt system and individual compo- nents may be checked with a millivolt meter having a 0-1000mv range. Conduct each check shown in chart by connecting meter test leads to terminals as indicated.

A.COMPLETE MILLIVOLT SYSTEM CHECK

("A" Reading - Thermostat contacts CLOSED - Control Knob “ON” - Main Burners should turn ON)

a.If the reading is more than 175 millivolts and the automatic valve still does not come on - replace the valve.

b.If the closed circuit reading ("A" reading) is less than 175 millivolts, determine cause for low reading - proceed as follows:

B.THERMOPILE OUTPUT READING CHECK

(“B” Reading - Thermostat contacts OPEN - Main burner OFF)

Check gas pressure to the unit. If gas pressure is within minimum and maximum on data plate, then replace pilot. If the minimum millivolt reading is not obtainable, replace pilot.
