VENT-FREE PROPANE/LP GAS COMPACT FIREPLACE
CGCFTP
CONNECTING TO GAS
SUPPLY
WARNING: A qualified service
person must connect fireplace 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
volume will occur.
WARNING: 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
23. Pointing the vent down protects it from
freezing rain or sleet.
Installation must include an equipment
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 24).
IMPORTANT: Install an equipment shutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on and
shutting off the gas to the appliance.
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.
We recommend that you install a sediment
trap in supply line as shown in Figure 24.
Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and fireplace. Locate
sediment trap where trapped matter is not
likely to freeze. A sediment trap traps mois-
ture and contaminants. This keeps them
from going into fireplace controls. If sedi-
ment 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 22.
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.

WARNING: This appliance re-
quires a 45° male flare fitting 5/8"-
18 UNF (Unified National Fine
Thread) inlet connection and the
flexible gas line provided.
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.
