For Knight Fire Tube boilers (WHN055-399), use PUM3020 for all models from 5 to 20 GPM flow rates.

Notes:

The chart includes recommended Gallon Per Minute flow rate, calculated Head Loss and recommended Pump.

The GPM, Ft/Hd and Pump selection is based on the boiler and the tank coil connected with maximum 20 feet of straight pipe, 4 - 90° elbows and 2 - full port ball valves.

See the Installation and Operation manual for more details including pipe diameters and piping diagrams.

Squire Indirect Storage tanks are for residential use only. Do not install Squire tanks in commercial applications with Knight XL or SYNC boilers.
