NOTES:
Note 1: Required Alliance SL Coil Flow Rate exceeds Max Allowable Flow Rate thru Boiler; this Boiler/Alliance SL combination may result in boiler heat exchanger
erosion and noise.
Note 2: Required Alliance SL Coil Flow Rate is below Min Required Flow Rate thru Boiler; this Model can only be installed as separate heating zone off system header

and corresponding coil head loss shown as well as total equivalent length of such separate zone.
Note 3: Combined Head Loss shown corresponds to Min Required Flow Rate thru Boiler.

When selecting Circulators with IFC contact Circulator Manufacturer for sizing information.
Near-Boiler Piping Size shown is based on 2 to 5.5 Ft/sec velocity range to avoid potential noise and pipe erosion.
