See Accessories, pages 24 and 25
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
Install sediment trap in supply line as shown
in Figure 16. Locate sediment trap where it
is within reach for cleaning. Locate sedi-
ment trap 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 is not installed or is installed
wrong, fireplace may not run properly.
INSTALLATION
Continued
Installation must include a manual 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 16).
Check your building codes for any special
requirements for locating manual shutoff
valve to fireplaces.
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in clogged fireplace valves.
Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• Phillips screwdriver
• sealant (resistant to propane/LP gas, not
provided)
1. Remove fireplace screen. Remove two
screws that hold fireplace screen in
place for shipping. These screws are
located near top of screen. Discard
screws. Lift fireplace screen up and pull
out to remove.
2. Remove screws that attach log base
assembly to fireplace (see Figure 17).
Carefully lift up log base assembly and
remove from fireplace (see Figure 17).
