Introduction

• The gas-fired condensing SSB 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 for venting including single pipe, two pipe
and concentric. See section "4.7 Venting and air piping system" 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 water quality section).
• 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 SSB boiler can be connected to a room thermostat.
• An outdoor air temperature sensor must also be connected to the
boiler for an outdoor reset supply temperature control for increased
fuel efficiency and comfort.
