Never use plastic pipe. Check to confirm whether your
local codes allow copper tubing or galvanized.

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 feet in length.
