Checking GAS Pressure

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. On all control type units, the inlet connection is on the right side of 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 completing connection. DO NOT USE AN OPEN FLAME.

Check the gas pressure with the appliance burning and the control set to HIGH.

MANUAL CONTROL (Figure 16)

The pressure regulator is preset and locked to discour- age tampering. If the pressure is not as specified, re-

place the regulator with the correct part from the parts list in this manual.

NPT Test Plug

Remove 1/8" NPT plug, located on either side of regu- lator body. Install fitting and tubing to pressure gauge. After taking pressure reading, reinstall test plug. Check for gas leaks.

MILLIVOLT CONTROL (Figure 18)

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 gas inlet). Af- ter taking pressure reading, be sure and turn captured screw clockwise firmly to reseal. Do not over torque. Check for gas leaks.
