CONNECTING FIREPLACE TO GAS SUPPLY
Installation Items Needed
•5/16" hex socket wrench or
•sealant (resistant to propane/LP gas, not provided)
1.Route flexible gas line (provided by in- staller) from equipment shutoff valve to fireplace. Route flexible gas supply line through one of the access holes on side of fireplace.
2.Attach flexible gas line from gas supply to control valve (see Figure 22).
3.Check all gas connections for leaks. See Checking Gas Connections.

CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections, internal and external to unit, for leaks after installing or servicing. Correct all leaks at once.
WARNING:Neveruseanopen flame to check for a leak. Apply noncorrosive leak detection fluid toalljoints.Bubblesformingshow 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 equipment 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 equip- ment shutoff valve was connected.
3.Pressurize supply piping system by either 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 sys- tem. Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
5.Reconnect fireplace and equipment shutoff valve to gas supply. Check recon- nected fittings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Figure 23).
2.Pressurize supply piping system by either 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.
3.Check all joints from propane/LP supply tank or gas meter to equipment shutoff valve (see Figure 24 or Figure 25, page
17). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.
4.Correct all leaks at once.
