Installation and Gas Connection

1. Place the burner pan assembly in the

center of the fireplace floor. Make sure

the front of pan faces forward.

2. Thread the gas supply fitting to the fire-

place gas supply pipe. Use thread sealant.

3. Install adapter fitting onto the burner inlet

fitting using thread sealant on male threads

of burner inlet fitting (see Figure 4).

4. Install the gas connector tube to the gas

supply fitting. Carefully shape tube to at-

tach to adapter fitting.

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 natural gas)

• equipment shutoff valve

• test gauge connection

• adjustable (crescent) wrench or pliers

• sediment trap

• tee joint

• pipe wrench

CAUTION: Only use a 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, loss of pres-

sure will occur.

Installation must include an equipment shut-

off 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 5).

IMPORTANT: Install equipment shutoff valve

in an accessible location. The equipment

shutoff valve is for turning on or shutting off

the gas to the appliance.

Figure 4 - Connecting Gas to Appliance

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.

Install sediment trap in supply line as shown

in Figure 5. 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 incorrectly, log set may

not run properly.
