PRODUCT DESCRIPTION
2.1
Introduction
• The gas-fired condensing Array boilers are designed to be used
in central heating systems. Any other use is prohibited.
• This boiler can be connected to an indirect storage tank for the
production of domestic hot water.
• There are several options available for venting. See section “4.15
Venting” for details.
• The quality of the system water is very important. Poor water
quality can damage heating systems and boilers due to
scale formation and corrosion (see section “4.6 Water quality
guidelines”).
• The boilers can also function directly with any hydronic emitter.
When installing the boiler and system connections, the installer
must consider the total head loss and flow rates in order to
adequately size piping and circulator pumps.
• The Array boiler can be connected to a room thermostat or by
a 0-10V input.
• An outdoor air temperature sensor must be connected to the
boiler for an outdoor reset supply temperature control for
increased fuel efficiency and comfort.
