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 175 Millivolts and the automatic valve still does not come on, replace the con-
trol.
b. If the closed circuit reading (“A” reading) is less than 175 Millivolts, determine cause for low reading, pro-
ceed 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, 500 Millivolts minimum. If the minimum Millivolt reading is not obtainable, replace pilot.
ChECkING 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.
