Connecting to GAS Supply

VENTED NATURAL GAS LOGS

INSTALLATION

Continued

WARNING: A qualified ser- vice person must connect log set to gas supply. Follow all local codes.

Installation Items Needed

Before installing log set, make sure you have the items listed below.

•piping (check local codes)

•sealant (resistant to propane/LP gas)

•manual shutoff valve

•test gauge connection

•adjustable (crescent) wrench or pliers

•sediment trap

•tee joint

•pipe wrench

CAUTION: Use only new, black iron or steel pipe. Inter- nally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" diameter or greater to allow proper gas volume to log set. If pipe is too small, undue loss of pressure will occur.

Install sediment trap in supply line as shown in Figure 6. Locate sediment trap where it is within reach for cleaning. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into log set controls. If sediment trap is not installed or is installed wrong, log set may not run properly.

*Purchase the optional A.G.A. design-certified manual shutoff valve from your dealer. See Accessories, page 18.

**Minimum inlet pressure for purpose of input adjustment.

Installation must include a manual shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from log set (see Figure 6).

Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in a clogged burner injector.

CAUTION: Use pipe joint seal- ant that is resistant to liquid pe- troleum (LP) gas.

CHECKING GAS

CONNECTIONS

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

WARNING: Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all 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

1.Disconnect log set and its individual manual shutoff valve from gas supply piping system.

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

3.Pressurize supply piping system by either using compressed air or opening main gas valve located on or near gas meter.

4.Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas joints. Bubbles form- ing show a leak.

5.Correct all leaks at once.

6.Reconnect log set and manual shutoff valve to gas supply. Check reconnected fittings for leaks.
