Leak Testing Heater Gas Connections

Pressure Test Gas Supply Piping System

The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of 1/2 psi.

The appliance must be isolated from the gas supply piping system by closing the individual manual shut-off valve (Fig. 7) during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psi.

1.Open manual shut-off valve.

2.Open main gas valve located near gas meter.

3.Make sure control knob of heater is in the OFF position.

4.Check all joints from manual gas valve up to control valve and including the manifold assembly. Apply the soap solution around the connections, valve and tubing. Soap bubbles will appear where a leak is present.

5.If a leak is present, immediately turn off gas supply, tighten any leaky fittings, turn gas on and recheck.

6.To check burner and safety valve, the burner must be lit (see Operating Instructions). Check the rest of the connections for leaks.

7.Turn off the heater.
