A. COMPLETE MILLI-VOLT SYSTEM CHECK
(“A” Reading - Thermostat contacts CLOSED - Control Knob “ON” - Main burner should turn ON)
a. If the reading is more than 175 milli-volts and the automatic valve still does not come on, replace the control.
b. If the closed circuit reading (“A” reading) is less than 175 milli-volts, 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, 500 milli-volts minimum. If the minimum milli-volt reading is not obtainable, replace pilot.
CHECKING SYSTEM OPERATION
The milli-volt system and individual com-
ponents may be checked with a milli-volt
meter having a 0-1000 mV range. Conduct
each check shown in chart below by con-
nection meter test leads to terminals as
indicated.
