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 system.

 

Pressures in excess of 1/2 psig will damage

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.

CHECKING GAS CONNECTIONS

WARNING: Test allgas piping 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 noncorrosive leak detec- tion fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.

CAUTION: Make sure exter- nal regulator has been installed between propane/LPsupply and fireplace. See guidelines under Connecting to Gas Supply, page 16.

1.Close equipment shutoff valve (see Fig- ure 27).

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 for natural or propane/LP supply to equipment shutoff valve (see Figures 28 and 29, page 19). Ap- ply a noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.
