CONNECTING TO GAS
SUPPLY

Figure 22 - External Regulator with Vent
Pointing Down

 WARNING: A qualified ser-

vice person must connect fire-
place to gas supply. Follow all
local codes.

 CAUTION: Never connect fire-

place directly to the propane/LP
supply. This fireplace requires
an external regulator (not sup-
plied). Install the external regula-
tor between the fireplace and pro-
pane/LP 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
incoming gas pressure, fireplace regulator
damage could occur. Install external regu-
lator with the vent pointing down as shown
in Figure 22. Pointing the vent down pro-
tects it from freezing rain or sleet.

Install sediment trap in supply line as shown
in Figure 23. 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 21.

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.

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 23).

IMPORTANT:

 Install main gas valve

(manual shutoff valve) in an accessible
location. The main gas valve is for turning
on or shutting off the gas to the appliance.

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.

**Minimum inlet pressure for purpose of input adjustment.

Extension Cord

Use extension cord if needed. The cord must
have a three-prong, grounding plug and a
three-hole receptacle. Make sure cord is in
good shape. It must be heavy enough to carry
the current needed. An undersized cord will
cause a drop in line voltage. This will result
in loss of power and overheating. Use a No.
16 AWG cord for lengths less than 50 feet.
