Pipe Diameter and Fuel Flow Rate
Pipe diameter determines the rate at which a fuel flows to the unit. To attain a workable flow rate, you must choose
a suitable pipe size.
• The required NG fuel flow-rate for the unit is 1,320 ft
3
/hr (37.38 m
3
/hr). To determine pipe diameter for your
application, see Table 1, below.
• The required LPL fuel flow-rate for the unit is
8.5 gph (32.2 Lph). To determine pipe diameter for your application, see
Table 2, below.
Note: Almost all operation problems are related to the installation techniques used. DO NOT guess; be sure pipe
diameter is adequate for required flow rate.
