The boiler is suitable for a wide range of applications. The boiler offers
numerous flue gas, hydraulic, gas and control application options, but,
at the same time, is not complicated to install. This and its moderate
dimensions, low noise levels and cascade options mean the boiler can
be installed almost anywhere (for general legal requirements, see
Section 12.2).
The choice of versions (open or closed combustion air supply)
provides excellent siting flexibility for the boiler. A motorised flue gas
discharge valve is available as an accessory and is used for
overpressure flue gas cascade arrangements. The boiler is equipped
with an enclosed housing that also serves as an air box. An air filter
and connection set are available for situations in which the boiler has
to be commissioned during the construction phase or has to operate
in a heavily polluted environment (this only applies to room ventilated
versions). Direct connection to structural ducts is not acceptable
because of condensation, see Chapter 7 for instructions and flue gas
discharge tables.
The advanced boiler control Comfort Master and relatively low
hydraulic resistance ensures that the boiler can be used in virtually
any hydraulic system.
The following types of control can be used for the boiler:
 as a single boiler or in a cascade with modulating controllers based
on room and/or outside temperature
 on/off controllers, using the boiler's internal heating curve if
necessary (in combination with outside temperature sensor)
 high/low controllers
 analogue signals (0-10 V or 0 - 20 mA) for control based on output
or flow temperature.
For further details, see Section 7.4.3.
The boiler is suitable for use with natural gas category I
