Space Heating; Domestic Hot Water With An Ibc Indirect Water Heater - IBC DC Series Installation And Operating Instructions Manual

WARNING
The correct 10KΩ temperature
sensor (or aquastat) must be
used to operate the indirect
water heater properly. If the
incorrect sensor is used
the domestic hot water may
overheat causing serious
injury or death.

2.5.2 Domestic Hot Water with an IBC Indirect Water
Heater
The DC series boiler / water heater can be connected to an IBC indirect water
heater. Connect the IBC indirect water heater's boiler / water heater supply and
boiler / water heater return connections to the boiler's primary loop (see Figure
#28, Page 1-26). Properly sized piping must be installed. A properly sized pump
must also be installed between the boiler / water heater and the IBC indirect
water heater.

2.6.1 Overview
The DC series boiler / water heater is designed to be installed in a primary/
secondary type piping system. The boiler / water heater comes complete with
a factory installed boiler pump. The pump is designed to circulate heating
system water through the boiler's heat exchanger and primary loop piping only.
The building's distribution piping system requires a dedicated pump or pumps
to provide circulation of the space heating water through the heating system.
The building pump or pumps will require a separate control system or relays to
operate the pumps.
Zoning of the space heating system can be accomplished many ways. Several
control packages are available from your local wholesaler and offer an easy
method of connecting the zoning system to the boiler / water heater. Example
piping and electrical drawings are available at www.ibcboiler.com
The boiler / water heater supplies heat to the space using an Outdoor
Reset Curve. With an outdoor sensor installed the boiler / water heater
will automatically adjust its space heating water temperature based on the
parameters programmed into the boiler / water heater. See separate publication
DC / HC Controller Manual for parameter information. If the Outdoor Sensor is
not installed, the boiler / water heater will use the temperature set in the User Set
Up menu "Boiler Supply Temperature" to supply hot water to the space heating
system.
