The size of the gas line used for installation is very important. If the line is too small, the gas pressure at the burner manifold will be low. This may cause slow recovery and delayed ignition. The incoming gas supply line should be a minimum of 1½” (38 mm) in diameter. Refer to the chart below for the minimum sizes of connection piping.

Gas Connection Pipe Sizes

(Minimum incoming pipe size should be 1 1/2" (38 mm))

				4 or more
Gas	Single Unit	2 - 3 Units		units*
Natural	3/4" (19 mm)	1" (25 mm)	1	1/4" (33 mm)
Propane	1/2" (13 mm)	3/4" (19 mm)		1" (25 mm)
Manufactured	1" (25 mm)	1 1/4" (33 mm)	1	1/2" (38 mm)

*For distances of more than 20 feet (6 m) and/or more than 4 fittings or elbows, increase the connection by one pipe size.

Before connecting new pipe to your unit, the pipe must be thoroughly blown out to remove any foreign particles. If these foreign particles get into the burner and controls, they will cause improper and sometimes dangerous operation.
