FIREPLACE FRAMING AND INSTALLATION (CONT'D)
• Solid fuels shall not be burned in this fireplace.
• The maximum gas inlet supply pressure is 11 in. for Propane
and 10.5 in. for Natural.
• 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 Propane and
4.5 in. Natural.
• 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: Never use plastic pipe. Check to confirm whether your local
codes allow copper tubing.
NOTE: Because some municipalities have additional local codes,
consult your local authority and installation code.
Installing a Manual Gas Shut-Off
Each fireplace must have an accessible manual gas shut-off 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.
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!
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 tee connected

and foreign particles may collect.
The use of the following gas connectors is recommended:
— ANSI Z21.24 A ppliance 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 Commonwealth of Massachusetts requires
that a flexible appliance connector cannot exceed three feet in length.
