• approved flexible gas hose and fittings (pro-
vided with heater) (if allowed by local codes)
• sealant (resistant to propane/LP gas, not
provided)
Note: Install optional HRC100 and HRC200
Receiver and Hand-Held Remote Control Kit
(see Accessories, page 26) before installing gas
log heater. See installation instructions included
with the kit.
1. Apply pipe joint sealant lightly to male
threads of gas fitting (not provided). Connect
approved flexible gas hose to inlet side of gas

CAUTION: Never connect
propane/LP fireplace directly
to the propane/LP supply. This
heater requires an external regu-
lator (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.
Installation Items Needed
Before installing heater, 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
• tee joint
• pipe wrench
• approved flexible gas line with gas connector
(if allowed by local codes) (provided)
* 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 regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming
gas pressure to between 11" and 14" of water. If you
do not reduce incoming gas pressure, heater regulator
damage could occur. Install external regulator with the
vent pointing down as shown in Figure 13. Pointing
the vent down protects it from freezing rain or sleet.
