INStallatIoN ItEMS NEEDED
Before installing fireplace and burner system, make sure
you have the items listed below.
•
Piping (check local codes)
•
Sealant (resistant to propane/LP gas)
•
approved flexible gas line with gas connector (if
allowed by local codes — not provided)
•
Equipment shutoff valve*
•
Sediment trap (recommended)
•
Tee joint
•
Pipe wrench
•
External regulator (supplied by installer) - LP Only
•
Test gauge connection*
* An equipment shutoff valve with a plugged tap is an
acceptable alternative to test gauge connection.

A qualified installer or service person must
connect appliance to gas supply. Follow all
local codes.

Use only new black iron or steel pipe.
Internally tinned copper or copper tubing
can be use, providing gas meets hydrogen
sulfide limits, and where permitted by local
codes. Gas piping system must be sized to
provide minimum inlet pressure (listed on
data plate) at the maximum flow rate (kw).
Undue pressure loss will occur if the pipe
is too small.
When using copper or flex connectors use only fittings
approved for gas connections. The gas control inlet is
RP 1/2"-14 straight pipe thread.

RNING
Only persons licensed to work with gas
piping may make the necessary gas
connections to this appliance.

N
A manual shutoff valve must be installed
upstream of the appliance. Union tee and
plugged pressure tapping point should be
installed upstream of the appliance.

NotE:
The gas line connection may be made using 1/2"
rigid tubing or an approved flex connector. Since some
municipalities have additional local codes it is always best
to consult your local authorities and the current edition of
the National Fuel Gas Code.
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 fireplace.
Check your building codes for any special requirements for
locating equipment shutoff valve to fireplaces.
Apply pipe joint sealant lightly to male threads. This will
prevent excess sealant from going into pipe. Excess seal-
ant in pipe could result in clogged burner system valve.
We recommend that you install a sediment trap/drip leg in
supply line as shown in
Figure 18
. Locate sediment trap/
drip leg where it is within reach for cleaning. Install in piping
system between fuel supply and burner system. Locate
sediment trap/drip leg where trapped matter is not likely
to freeze. A sediment trap collects moisture and contami-
nants and keeps them from going into the burner system
gas controls. If sediment trap/drip leg is not installed or is
installed wrong, burner system may not run properly.
