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.
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)
