portant information, which is a base
for safe and reliable installation,
commissioning and operation of the
boiler. All activities described in this
document may only be excecuted by
authorized companies.
Changes to this document may be
effected without prior notice. We ac-
cept no obligation to adapt previously
delivered products to incorporate
such changes.
Only original spare parts may be
used when replacing components on
the boiler, otherwise warranty will be
void.
Application

and hot water production purposes
only. The boiler should be connected
to closed systems with a maximum
temperature of 100ºC (high limit
temperature), maximum setpoint
temperature is 90ºC.

Operating principle
This is a fully modulating boiler.
The control unit of the boiler adapts
the modulation ratio automatically to
the heat demand requested by the
system. This is done by controlling
the speed of the fan.
As a result, the Whirlwind mixing
system will adapt the gas ratio to the
chosen fan speed, in order to maintain
