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 unit. To connect from the opposite side, route the pipe around the back 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.
