CONNECTING TO GAS

SUPPLY

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)

• equipment 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.

We recommend that you install a sediment

trap in supply line as shown in Figure 2,

page 3. Locate sediment trap where it is

within reach for cleaning. Install in piping

system between fuel supply and heater. Lo-

cate 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.

Installation must include an equipment

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 2, page 3).

IMPORTANT:

Install equipment shutoff

valve in an accessible location. The equip-

ment shutoff valve is for turning on or

shutting off the gas to the 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 orifice.

CAUTION: Use pipe joint seal-

ant that is resistant to liquid pe-

troleum (LP) gas.

CHECK GAS TYPE

You must install this ON/OFF Safety Valve/

Pilot Kit if your gas type is propane/LP.

For additional convenience and safety, this

ON/OFF Safety Valve/Pilot Kit can be

used with natural gas. If you are unsure of

the proper application, call dealer where

you bought log set.

If the fireplace does not have a gas supply

shutoff valve, one must be installed.
