Figure 7-3 Water side head loss of the heater
7.2.4 - Local boiler pump
and CH pump
This boiler must be fitted with a local
pump. To connect the local pump to
the boiler see Figures 7-4 and 7-5
and electrically connect the pump on
terminals as shown on Figure 10-4.
A field supplied pump relay must be
installed if the pump current draw is
greater than 3 amps.
The water resistance to size the
local pump to supply flow through
the heating system at the boiler
connections is shown in graph form in
Figure 7-3.
CAUTION!!!
It is up to the
installer to ensure the minimum
system flow is not less than 4
GPM at any time. If the flow is
lower, the boiler automatically
stops the burner.
To connect an heating pump (CH
pump) on the secondary loop see
Figures 7-4 and 7-5 and electrically
connect the pump on terminals as
shown on Figure 10-4. A field supplied
pump relay must be installed if the
pump current draw is greater than 3
amps.
7.2.5 - Sizing heating
system
Size the pump, piping and system
components required in the space
heating system, using recognized
design methods.
7.2.6 - Domestic Hot
Water system Piping
when using an indirect
water heater
See Figures 7-4 and 7-5, for
recommended piping to an indirect
water heater. This recommended
piping configuration ensures priority is
given to the production and recovery
of DHW. Refer to Figure 10-4 to wire
the indirect water heater pump (DHW
pump)
Anti-scald mixing valve: Field
supplied. An anti-scald mixing valve is
mandatory on the domestic hot water
outlet of the indirect water heater
WARNING!!!
WARNING!!!
Install an anti
scald mixing valve downstream
domestic hot water piping.
Failure to comply with this
provision can result in scalding
of individuals and animals
causing, severe personal injury
or death!
