CHECKING GAS CONNECTIONS

WARNING:Testallgaspiping and connections , internal and external to unit, for leaks after installing or servicing. Correct all leaks at once.

WARNING: Never use an open flame to check for a leak. Apply a commercial leak de- tection solution to all joints. Bubbles forming show a leak. Correct all leaks at once.

CAUTION: For propane/LP units, make sure external regula- tor has been installed between propane/LP supply and heater. SeeguidelinesunderConnecting to Gas Supply, page 13.

PRESSURE TESTING GAS SUPPLY PIPING SYSTEM

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

1.Disconnect appliance with its appliance main gas valve (control valve) and equipment shutoff valve from gas supply piping. Pressures in ex- cess of 1/2 psig will damage heater regulator.

2.Cap off open end of gas pipe where equipment shutoff valve was connected.

3.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas or using compressed air.

4.Check all joints of gas supply piping system. Apply a commercial leak detection solution to all joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Reconnect heater and equipment shutoff valve to gas supply. Check reconnected fittings for leaks.

Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)

1.Close equipment shutoff valve (see Figure 15).

2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas or using compressed air.

3.Check all joints from gas meter (natural gas) or propane/LP supply to equipment shutoff valve (see Figure 16 or 17). Apply a commercial leak detection solution to all joints. Bubbles forming show a leak.

4.Correct all leaks at once.
