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 24).
IMPORTANT: Install an equipment shutoff valve
in an accessible location. The equipment shutoff
valve is for turning on and 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 liq-
uid petroleum (LP) gas.
We recommend that you install a sediment trap in
supply line as shown in Figure 24. Locate sediment
trap where it is within reach for cleaning. Install in
piping system between fuel supply and fireplace.
Locate sediment trap where trapped matter is not
likely to freeze. A sediment trap traps moisture and
contaminants. This keeps them from going into fire-
place controls. If sediment trap is not installed or is
installed wrong, fireplace may not run properly.
