he gas pipeline can be brought in through the right or left
side of the appliance. Consult the current National Fuel Gas
Code, ANSI Z223.1 CAN/CGA-B149 (.1 or .2) installation
code.
Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be 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. Appliance
must be disconnected from piping at inlet of control valve
and pipe capped or plugged for pressure test. Never
pressure test with appliance connected; control valve
will sustain damage!
NOTE:
The millivolt gas controls are equipped with a captured
screw type pressure test point, therefore it is not necessary
to provide a 1/8" test point up stream of the control.
On direct ignition valves, hex plugs may be replaced with
hose fittings for pressure checks, then reinstalled before
operating fireplace.
When using copper or flex connector use only approved
fittings.
The appliance 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
(3.5kPa).
The appliance 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 (3.5kPa).
Attention!
If one of the procedures results in pressures in
excess of 1/2 psig (14" w.c.) (3.5 kPa) on the fireplace gas
valve, it will result in a hazardous condition.
Checking Manifold pressures
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a
manifold pressure of approximately 3.5" w.c. (.871kPa) at the
valve outlet with the inlet pressure to the valve from a minimum
of 4.5" w.c. (1.120kPa) for the
purpose of input adjustment
to a maximum of 14.0" w.c.
(3.484kPa). Propane gas
models will have a manifold
pressure approximately 10.0"
w.c. (2.49kPa) at the valve
outlet with the inlet pressure
to the valve from a minimum
of 10.8" w.c. (2.68kPa) for the
purpose of input adjustment
to a maximum of 14.0" w.c.
(3.484kPa).

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:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings.
— ANS 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.
