INSTALLING GAS PIPING TO
FIREPLACE LOCATION
Installation Items Needed
Before installing fireplace insert, make sure
you have the items listed below.
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connec-
tor (if allowed by local codes) (not provided)
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur-
chase the optional CSA design-certified
equipment shutoff valve from your dealer.
See Accessories, page 26.
WARNING: A qualified ser-
vice person must connect fire-
place Insert to gas supply. Fol-
low all local codes.
WARNING: Never connect
fireplace insert to private (non-
utility) gas wells. This gas is com-
monly 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"
diameter or greater to allow
proper gas volume to fireplace
insert. 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.
We recommend that you install a sediment
trap in supply line as shown in Figure 17.
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 insert gas controls. If
sediment trap is not installed or is installed
wrong, fireplace may not run properly.
Installation must include an equipment
shutoff valve, and plugged 1/8" NPT tap.
Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from
fireplace insert (see Figure 17).
IMPORTANT:
Install equipment shutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on or
shutting off the gas to the appliance.
Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• Phillips screwdriver
• sealant (resistant to propane/LP gas, not
provided)

Mantel Clearances for Insert
Installation
If there is a mantel above masonry fireplace,
you must meet minimum clearance between
mantel shelf and top of fireplace opening.
NOTICE: Surface temperatures of
adjacent walls and mantels be-
come hot during operation. Walls
and mantels above the firebox
may become hot to the touch. If
installed properly, these tempera-
tures meet the requirements of
the national product standard.
Follow all minimum clearances
shown in this manual.

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.
