a gas leak. Apply a mixture of liquid soap and water 

to all joints. Bubbles forming show a leak. Correct 

all leaks at once. 

SYSTEM
High Pressure 
Test pressure in Excess of ½ psig (3.5kPa)

1.  Disconnect appliance with its appliance main 

gas valve (control valve) and equipment shutoff 

valve from gas supply piping system. Pressures 

in excess of ½ psig will damage heater regula-

tor.

2.  Cap off open end of gas pipe where equipment 

shutoff valve was connected.

3.  Pressurize supply piping system by either using 

compressed air or opening main gas valve on 

or near gas meter.

piping system. Apply mixture of liquid soap and 

water to gas joints. Bubbles forming show a 

leak.

5.  Correct all leaks at once.
6.  Depressurize and relieve pressure in supply 

piping system.

7.  Reconnect heater and equipment shutoff valve 

to gas supply. 

8.  Reconnected fittings must be checked for leaks 

in next section. 

Low Pressure
Test Pressure Equal To or Less Than ½ psig (3.5 

kPa)

1.  Close equipment shutoff valve (see figure 13).
2.  Pressurize supply piping system by either using 

compressed air or opening propne/LP supply 

valve.

3.  Check all joints from the propane/LP supply 

valve to equipment shutoff valve (see figure 

14). Apply mixture of liquid soap and water to 

gas joints. Bubbles forming show a leak.

4.  Correct all leaks at once.
5.  Depressurize and relieve pressure from supply 

piping system.

tem is connected and has been leak tested as 

described above.

2.  Make sure control knob of heater is in OFF 

position.

3.  Open equipment shutoff valve (see figure 13).
