CHECKING GAS PRESSURE
WARNING WARNING
Connecting directly to an unregulated propane/LPG tank can cause an explosion.
The heater gas inlet connection is a 3/8" NPT at the valve. All units have the inlet connection on the right side, when you face the unit. To connect from the opposite side, route the pipe under the rear portion of the unit.
When tightening up the joint to the valve, hold the valve securely to prevent movement.
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.
MANUAL CONTROL (Figure 14)
The pressure regulator is preset and locked to dis- courage tampering. If the pressure is not as specified, replace the regulator with the correct part from the parts list in this manual.
Remove 1/8" NPT plug, located on side of regulator body. Install fitting and tubing to pressure gauge. After taking pressure reading, reinstall test plug. Check for gas leaks.
MILLIVOLT CONTROL (Figure 15)
The valve regulator controls the burner pressure which should be checked at the pressure test point.
Turn captured screw counter clockwise two or thre 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
