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 of
f system header
- see
Figures
32C
and
32D
for
alternate
IWH
piping.

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
.

are
not
equipped
with

(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.
