Connecting Fireplace To Gas Supply - Desa Comfort Glow LFP33PR Owner's Operation And Installation Manual

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, page 10).
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.
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 17. 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.
