FIREPLACE
INSTALLATION
Continued
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.
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.
