FIREPLACE FRAMING AND INSTALLATION
•
Solid fuels shall not be burned in this fireplace.
•
The maximum gas inlet supply pressure is 11 in. for LP and
10.5 in. for NAT.
•
For fireplaces for fixed fuel piping system and equipped with
a fireplace gas pressure regulator, the required manifold
pressure in inches water column: 11 in. for LP and
4.5 in. NAT.
•
For fireplaces for fixed fuel piping system and equipped with
a fireplace gas pressure regulator, the fireplace and its indi-
vidual shutoff valve must be disconnected from the gas sup-
ply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psi (3.5 kPa).
The fireplace must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psi (3.5 kPa).
Check all local codes for requirements, especially for the size and
type of gas supply line required.

Note: Check to confirm whether your local codes allow plastic or
copper tubing for outdoor use.
Note: Because some municipalities have additional local codes,
consult your local authority and installation code.
Installing a Manual Gas Shut-off Valve
Each fireplace must have an accessible manual gas shut-off valve
located in the vicinity of the unit. Where none exists, or where its size
or location is not adequate, contact your local authorized installer
for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made. To avoid damage to
the gas piping, removal all testing solution when testing is complete.
Never use an exposed flame to check for leaks. Fireplace
must be disconnected from piping at inlet of control valve and
pipe capped or plugged for pressure test. Never pressure test
with fireplace connected; control valve will sustain damage!

WARNING
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required by
the National Fuel Gas Code that a drip line be installed near the
gas inlet. This should consist of a vertical length of pipe connected
into the gas line by a tee fiting with a cap on the bottom in which
condensation and foreign particles may collect.
The use of the following gas connectors is recommended:
— ANSI Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings
— ANSI Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction The state of Massachusetts requires that a flexible
appliance connector cannot exceed three feet in length.
