GAS SUPPLY
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.

Note: Never use plastic pipe. Check to confirm whether your
local codes allow copper tubing or galvanized.
Note: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
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.

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 16. 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.
A manual main gas shut-off valve should be located in the vicinity
of the fireplace. 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!
NOTE:
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 17.
When using copper or flex connector use only approved fittings.
The fireplace and it’s 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).
The fireplace must be isolated from the gas supply piping system
by closing its individual manual shut off valve during any pressure
testing of the gas supply piping system at test pressures equal to
or less than 1/2 psig (3.5 kPa).
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14in w.c.) (3.5 kPa) on the fireplace gas valve, it will
result in a hazardous condition.
