The operation of the circulating pump is controlled by the
SOLA temperature control .When the appliance is activated by
a remote operating signal the pump will start and run for the
operating cycle and for a post purge period based on
temperature difference between inlet and outlet connections to
the appliance.
To select the proper pump it is strongly recommended to
consider the following:
•
Need to know the required flow (GPM) and pressure drop
for your appliance (see Table 8 or 9)
•
Type of application, hydronic heating or Domestic Hot
Water (DHW).
•
Copper or Copper Nickel Heat Exchanger: For hydronic
heating and DHW applications with normal water hardness
choose a pump which will result in a temperature rise
across the main heat exchanger of 30ºF to 35 ºF (17ºC-
19ºC). If necessary use a flow setter valve to achieve the
desired temperature rise.
•
Stainless Steel Heat Exchanger: For hydronic heating
and DHW applications with normal water hardness choose
a pump which will result in a temperature rise across the
main heat exchanger of 20ºF to 25 ºF (11ºC-14ºC). If
necessary use a flow setter valve to achieve the desired
temperature rise.
•
For DHW applications with other than normal water
hardness choose a pump for the local water hardness
conditions. Alternatively run the pump continuously and
soften the water to normal levels. Damage to the heat
exchanger as a result of scaling or corrosive water
conditions is non-warrantable.
4.14.2 CIRCULATING PUMP SELECTION CONDENSOR
The operation of the circulating pump may be continuous or it
may be in parallel with the main heat exchanger pump. Size
the secondary pump for a minimum flow of 10% of the flow
through the main heat exchanger and a maximum of 30% of
the main heat exchanger flow up to 60 GPM.

DynaFlame® boilers supplied at 460/3/60 voltage, differ
from the standard unit per the following:
CAUTION!
While working with 460V circuits it is imperative that extra
precautions be taken
- Ensure that lock-out/ tag-out procedures are strictly
enforced
- Only properly trained and authorized personnel should
be permitted to work on live electrical circuits
- All electrical workers should be trained in electrical
rescue techniques and CPR
Each unit has an internal factory mounted 500VA
transformer to supply the single leg 115V necessary for
the ignition circuit, which is factory mounted. The boiler
itself is a single point power connection. A new Variable
Frequency Drive replaces the standard VFD, and the
combustion blower fan has been configured to operate at
460/3/60V (using the standard fan). Part numbers as well
as FLA and MOCP information is below.
