Note 3
NOTES:
Note 1: Required Alliance SL Coil Flow Rate exceeds Max Allowable Flow Rate through 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 through Boiler; this Model can only be installed as separate heating zone off
system header - see Figure 24A for alternate IWH
piping. Indirect Water Heater Circulator must be selected by an installer based on Alliance SL required coil flow 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 through Boiler.
* Circulator Models shown are not equipped with internal flow check valve (IFC).
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.
