NATURAL GAS VENT-FREE FIREPLACE SYSTEM
CONNECTING TO GAS
SUPPLY
WARNING: A qualified ser-
vice person must connect fire-
place to gas supply. Follow all
local codes.
IMPORTANT: Check gas line pressure be-
fore connecting fireplace to gas line. Gas
line pressure must be no greater than 14
inches of water. If gas line pressure is higher,
fireplace regulator damage could occur.
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 23).
IMPORTANT: Install main gas valve
(equipment shutoff valve) in an accessible
location. The main gas valve is for turning
on or 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.
WARNING: Never connect
fireplace to private (non-utility)
gas wells. This gas is commonly
known as wellhead gas.
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 al-
low proper gas volume to fire-
place. If pipe is toovolume pres-
sure will occur.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
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
package is provided with fireplace.
1. Drill holes at marked locations using
5/16" drill bit. For solid floors (con-
crete 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.

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.
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.
We recommend that you install a sediment
trap in supply line as shown in Figure 23.
Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and heater. 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.
