CONNECTING TO GAS
SUPPLY
Figure 16 - External Regulator with Vent
Pointing Down
NOTICE: A qualified service per-
son must connect fireplace to
gas supply. Follow all local codes.
CAUTION: Never connect fire-
place directly to the propane sup-
ply. This fireplace requires an ex-
ternal regulator (not supplied). In-
stall the external regulator between
the fireplace and propane supply.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of 1/2"
or greater diameter to allow
proper gas volume to fireplace. If
pipe is too small, undue loss of
pressure will occur.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
The installer must supply an external regu-
lator. The external regulator will reduce
incoming gas pressure. You must reduce
incoming gas pressure to between 11 and 14
inches of water. If you do not reduce incom-
ing gas pressure, fireplace regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure
16. Pointing the vent down protects it from
freezing rain or sleet.
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 17).
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.
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 controls. If sediment
trap is not installed or is installed wrong,
fireplace may not run properly.

Attaching Wood Base to Solid
Floor
For attaching base to solid floors (concrete
or masonry)
Note: Floor anchors and mounting screws
are in hardware package. The hardware pack-
age is provided with fireplace.
1. Drill holes at marked locations using
5/16" drill bit. For solid floors (concrete
or masonry), drill at least 1" deep.
2. Fold floor anchor as shown in Figure 15.
3. Insert floor anchor (wings first) into
hole. Tap anchor flush to floor.
4. Insert mounting screws through base
and into floor anchors.
5. Tighten screws until base is firmly fas-
tened to floor.
