The 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.

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 liqueed 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.

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 ttings
for pressure checks, then reinstalled before operating replace.
When using copper or ex connector use only approved ttings.
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 (3.5 kPa).
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 (3.5 kPa).
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the replace gas valve, it will
result in a hazardous condition.

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. (.871 kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 4.5" w.c.
(1.120 kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484 kPa). Propane gas models will have a manifold
pressure approximately 10.0" w.c. (2.49 kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 10.8" w.c.
(2.68 kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484 kPa).

Note: Never use plastic pipe. Check to conrm 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 exible
appliance connector cannot exceed three feet in length.
