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.
We recommend that you install a sediment
trap/drip leg in supply line as shown in Figure
19. Locate sediment trap/drip leg where it is
within reach for cleaning. Install in piping sys-
tem between fuel supply and fireplace. Locate
sediment trap/drip leg where trapped matter
is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them
from going into fireplace gas controls. If sedi-
ment trap/drip leg is not installed or is installed
wrong, fireplace may not run properly.
