Installation must include an equipment shutoff
valve, union, and plugged 1/8" NPT tap. Lo-
cate NPT tap within reach for test gauge hook
up. NPT tap must be upstream from
fi replace
(see Figure 18).
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.
Check your building codes for any special
requirements for locating equipment shutoff
valve to
fi replaces.
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
fi replace valves. Never use
sealant on fl are threads.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
We recommend that you install a sediment
trap in supply line as shown in
Figure 18
.
Locate sediment trap where it is within reach
for cleaning. Install in piping system between
fuel supply and
fi replace. Locate sediment
trap where trapped matter is not likely to
freeze. A sediment trap traps moisture and
contaminants. This keeps them from going
into
fi replace gas controls. If sediment trap
is not installed or is installed wrong, fi replace
may not run properly.
