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 fireplace.

If pipe is too small, undue loss

of volume will occur.

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 fireplace (see

Figure 31).
IMPORTANT

: Install main gas valve (equipment

shutoff valve) in an accessible location. The main

gas valve is for turning on or shutting off the gas

to the appliance.

Check your building codes for any special re-

quirements for locating equipment shutoff valve

to fireplaces.

Apply pipe joint sealant lightly to male NPT

threads. This will prevent excess sealant from

going into pipe. Excess sealant in pipe could result

in clogged fireplace valves.

WARNING: Use pipe joint

sealant that is resistant to liquid

petroleum (LP) gas.

FIREPLACE

INSTALLATION

Continued

We recommend that you install a sediment trap/

drip leg in supply line as shown in Figure 31. Lo-

cate 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 sedi-

ment trap traps moisture and contaminants. This

keeps them from going into fireplace gas controls.

If sediment trap/drip leg is not installed or is in-

stalled wrong, fireplace may not run properly.
