Inlet Gas Line Sizing; Inlet Gas Requirements - ULTRAFRYER Systems PAR-3-HE Operating Instructions Manual

I. INLET GAS LINE SIZING:
The Table below is used to calculate the size (diameter) of the inlet gas line from the building regulator to the fryer manifold.

NOTE: 1) FT 3 /HR (M 3 /HR) values may vary due to heating value and specific gravity of gas supplied by local companies.
2) To determine the inlet gas line diameter for the distance between the fryer and main gas regulator, locate the FT 3 /HR (M 3 /HR) of gas required for the fryer and
pipe length and read the pipe diameter on the top row. For example: a 18" PAR-3-HE fryer operating on NATURAL GAS requires 110 FT 3 /HR (3.1 M 3 /HR)
of gas at the fryer's inlet gas manifold. If the fryer bank is located 60 feet from the building gas regulator, a 1" (25mm) diameter gas line MUST be installed
between the manifold and regulator.

NOTE: The flexible gas line used to connect the gas manifold to the building gas supply line must rated for the BTU/Hr (MJ/Hr) for the Fryer.
For example: the BTU/Hr (MJ/Hr) rating for a PAR-3-HE fryer is 110,000 BTU/Hr (116 MJ/Hr) and therefore would require a 3⁄4" diameter
gas line.
The Flexible Gas Line used to connect the gas manifold to the building gas supply line must be rated for the BTU/Hr (MJ/Hr)
designated for the Fryer. Flexible gas lines and their ratings stocked by Ultrafryer Systems are listed below:
