We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 32. Locate sediment trap/drip leg where it is within reach for cleaning. Install in piping system between fuel supply and fireplace. Locate sediment trap/drip leg where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into fireplace gas controls. If sediment trap/drip leg is not installed or is installed

CONNECTING FIREPLACE TO GAS SUPPLY

Installation Items Needed

• 5/16" hex socket wrench or nut-driver

• sealant (resistant to propane/LP gas, not pro- vided)

1. Open lower louver door panel by gently pulling forward.

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

3. Attach flexible gas line from gas supply to control valve (see Figure 33).

4. 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 equip- ment 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 equipment 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 system. 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 reconnected fittings for leaks.
