Locating Gas Supply
The gas line can enter the unit either through the floor or outside wall.
The gas line opening should be made at this time. Location of the opening
will be determined by the position of floor joists and the valve and union
used for servicing.
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.
