Never use plastic pipe. Check to confirm whether your
local codes allow copper tubing or galvanized.
NOTICE
:
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 Commonwealth of Massachusetts
requires that a flexible appliance connector cannot exceed three

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 13.
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.
