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 tting (not provided). Connect

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 exible gas line with gas connector
(if allowed by local codes) (provided)
* A CSA design-certied equipment shutoff valve
with 1/8" NPT tap is an acceptable alternative to
test gauge connection. Purchase the optional CSA
design-certied 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.
