WARNING: This appliance requires a 1/2" NPT
(National Pipe Thread) inlet connection to the pres-
sure regulator.
WARNING: A qualified service person must con-
nect fireplace to gas supply. Follow all local codes.
CAUTION: Never connect propane/LP fireplace
directly to the propane/LP supply. This heater requires
an external regulator (not supplied). Install the external
regulator between the heater and propane/LP supply.
WARNING: Never connect natural gas fireplace to
private (non-utility) gas wells. This gas is commonly
known as wellhead gas

CAUTION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in certain
areas. Check your local codes. Use pipe of 1/2" diam-
eter or greater to allow proper gas volume to fireplace.
If pipe is too small, undue loss of volume will occur.

Installation Items Needed
Before installing fireplace, make sure you have the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap (optional)
• tee joint
• pipe wrench
* A CSA design-certified equipment shutoff valve with 1/8" NPT tap
is an acceptable alternative to test gauge connection. Purchase the
optional CSA design-certified equipment shutoff valve from your
dealer. See Accessories, page 26.
For propane/LP units, the installer must supply an external regula-
tor. 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, heater regulator
damage could occur. Install external regulator with the vent point-
ing down as shown in Figure 17. Pointing the vent down protects it
from freezing rain or sleet.
Figure 18 - Gas Connection
* Purchase the optional CSA design-certified equipment shutoff
valve from your dealer. See Accessories, page 26.
** Minimum inlet pressure for purpose of input adjustment.
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 18).
WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.
We recommend that you install a sediment trap in supply line as
shown in Figure 18. 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 moisture and contaminants. This keeps them
from going into fireplace gas controls. If sediment trap is not
installed or is installed wrong, fireplace may not run properly.

IMPORTANT:
Install equipment shutoff valve in an accessible
location. The equipment shutoff 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.
