Checking GAS Connections

INSTALLATION

Continued

4.Apply pipe joint sealant lightly to male threads of gas connector attached to ﬂexible gas line/ equipment shutoff valve (see Figure 26).

5.Check all gas connections for leaks. See Checking Gas Connections.

6.Replace branch support back into ﬁreplace. Feed ﬂexible gas line into ﬁreplace base area while replacing branch support. Make sure the entire ﬂexible gas line is in ﬁreplace base area. Reattach branch support to ﬁreplace with screws removed in step 2 on page 17.

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
	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 noncorrosive leak detection ﬂuid to

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.
