Check System Operation

The millivolt system and individual components may be checked with a millivolt meter having a 0-1000 mV range. Conduct each check shown in chart below by connection meter test leads to terminals as indicated.

A.Complete MilliVolt System Check

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

a.If the reading is more than 100 millivolts and the automatic valve still does not come on, replace the control.

b.If the closed circuit reading (“A” reading) is less than 100 millivolts, determine cause for low reading, proceed to Section B below.

B.Thermopile Output Reading Check

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

1. Check gas pressure to the unit. If gas pressure is within minimum and maximum on data plate, then check pilot voltage, 325 millivolts minimum. If the minimum millivolt reading is not obtainable, replace pilot.
