The gas pipeline can be brought in through the right side of the
fireplace. Consult the current National Fuel Gas Code, ANSI
Z223.1 CAN/CGA-B149 (.1 or .2) installation code.
NotICE: Never use plastic pipe. Check to confirm whether your
local codes allow copper tubing or galvanized.
NotICE: Because some municipalities have additional local
codes, consult your local authority and installation code.
The following gas connectors are 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 Commonwealth of Massachusetts
requires that a flexible appliance connector cannot exceed three
feet in length.

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 leg be installed near the
gas inlet. See Figure 15. This should consist of a vertical length
of pipe tee connected into the gas line that is capped on the
bottom in which condensation and foreign particles may collect.
Installing a New Main Gas Shut-Off Valve (Check Local Code)
Each fireplace should have its own manual gas shut-off valve
14.0
located in the vicinity of the fireplace. Where none exists, or
where its size or location is not adequate, contact your local
14.0
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. Use a soap solution
while watching for bubbles on all exposed connections. For
unexposed pipe connections conduct a pressure test. Fireplace
must be disconnected from piping at inlet of control valve and
pipe capped or plugged for pressure test.
Never use an exposed flame to check for leaks.
Never pressure test with fireplace connected; control valve
will sustain damage! To prevent damage or injury, the fireplace
and its individual shut-off valve must be disconnected from
supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5 kPa).
NotICE: The gas control is equipped with a captured screw type
pressure test point; therefore it is not necessary to provide a 1/8
inch test point up stream of the control. See Figure 16.
When using copper or flex connector use only approved fittings.
