  2. Connect the two (2) 1/4" 
female connectors to the 
TP/TH and TH terminals 
on the control valve.
  3. Connect  the  four-pin 
connector from the valve 
motor to the four-pin con-
nector on the receiver.

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
