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, 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, 325 millivolts minimum. If the
minimum millivolt reading is not obtainable, replace
pilot.
