NOTE:
1) FT3/HR (M3/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 FT3/HR (M3/HR) of gas required for the fryer and
pipe length and read the pipe diameter on the top row. For example: a 14” PD fryer operating on
NATURAL GAS
requires 105 FT3/HR (3.0 M3/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.
