CHECKING GAS

CONNECTIONS

WARNING: Test all gas pip- ing and connections for leaks after installing or servicing. Cor- rect all leaks at once.

3.

Pressurize supply piping system by ei-

 

ther opening propane/LP supply tank

 

valve for propane/LP gas fireplace or

 

opening main gas valve located on or near

 

gas meter for natural gas fireplace, or

 

using compressed air.

4.

Check all joints of gas supply piping

 

system. Apply commercial leak test so-

 

lution to all gas joints. Bubbles forming

5/16" hex socket wrench or nut-driver

sealant (resistant to propane/LP gas, not provided)

1.Open lower louver door panel by gen- tly pulling forward.

2.Route flexible gas line (provided by installer) from manual shutoff valve to fireplace. Route flexible gas supply line through one of the access holes on side of fireplace.

3.Attach a 45° flare union gas connector to flexible gas line from gas supply (see Figure 37). Connect flare union to flex- ible gas line attached to gas regulator of fireplace (see Figure 37).

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

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

Pressure Testing Gas Supply Piping System

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

1.Disconnect fireplace and its individual manual shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig (3.5 kPa) will damage fireplace gas regulator.

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