When tightening up the joint to the valve, hold the valve securely 
to prevent movement. 
MILLI-VOLT  VALVE CONTROL 
(Figure 16)
The valve regulator controls the burner pressure which 
should be checked at the pressure test point.
Turn captured screw counter clockwise two or three 
turns and then place tubing to pressure gauge over test 
point (Use test point “OUT” closest to control knob). 
After taking pressure reading, be sure and turn captured 
screw clockwise firmly to re-seal. Do not over torque. 
Check for gas leaks.
Test all gas joints from the gas meter to the heater valve for leaks using a gas analyzer or soap and water solution after com-
pleting connection. DO NOT USE AN OPEN FLAME.
Check the gas pressure with the appliance burning and the control set to HIGH.
