Installation must include an equipment shutoff valve, and plugged 1/8"
NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap
must be upstream from fireplace insert (see Figure 14).
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 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.

Connecting Fireplace Insert To Gas Supply
We recommend that you install a sediment trap in supply line as
shown in Figure 14. Locate sediment trap where it is within reach for
cleaning. Install in piping system between fuel supply and heater.
Locate sediment trap where trapped matter is not likely to freeze. A
sediment trap traps moisture and contaminants. This keeps them
from going into fireplace insert gas controls. If sediment trap is not
installed or is installed wrong, fireplace may not run properly.
