• Technical Data
Colora 24
kW
open
flued gas combination boiler (CA 24
BB)
is
a B type boiler
(EN
297). B type
boilers have
an
open
combustion chamber. Combustion air
is
provided from the installation
room
and
products of combustion
is
discharged
by
means of approved flue ducts connections
and
a chimney. Therefore, they are
named
as room air
dependent
gas appliances.

room sealed fan assisted gas combination boilers (CA 24
HB,
CA 24
HM,
CA 28
HM)
is
a C type boiler
(EN
483). C type boilers have a sealed combustion chamber.
Required
fresh
air for combustion
is
provided independently from the installation room
by
concentric air/flue ducts
and
products
of
combustion
can
be
also discharged
by
the same
air/flue ducts. Therefore, they are
