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 fireplace
(see Figure 22).
IMPORTANT: Install equipment shutoff valve
in an accessible location. Equipment shutoff
valve is for turning on or shutting off 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.

1. To remove fireplace screen, remove 2
screws that hold fireplace screen in place
for shipping. These screws are located
near top of screen. Discard screws. Lift fire-
place screen up and pull out to remove.

nections. A flexible gas line is
provided to allow accessibility
from the fireplace (see Figure 23).
The flexible gas supply line con-
nection to the equipment shutoff
valve should be accessible.
CAUTION: Avoid damage to
