Combustion product removal
The
BioClass HC
boiler is an assembly of two
BioClass HM
boilers and it is essential that each boiler
is connected to a flue, i.e. a smoke duct able to create a pressure drop (which in this case should be
between 0.10 and 0.20 mbar), in compliance with the applicable laws to this regard.
The combustion product exhaustion ducts must be installed by qualified personnel and must
comply with the regulations in force. For the flue to create a pressure drop, the following
recommendations should be taken into account:
- It should be suitably insulated.
- It should be vertical, avoiding any angles greater than 45º.
- It should always have the same diameter. It is recommendable for it to be circular, and never
any narrower than the boiler outlet.
-
It is obligatory to install a fume inspection plate with condensation collection, to remove
the condensation generated in the flue.
Otherwise, the condensation may reach the inside of
the boiler and cause irreparable damage,
which would not be covered by DOMUSA TEKNIK’s
guarantee
.
The condensation pipe should lead to a drain outlet
, as a large amount of water
may be generated. This connection must be made in compliance with the regulations for
draining off condensation water to the drain network.
-
It is recommended to install a draught stabiliser
to prevent any pressure drop variations in
the flue due to atmospheric conditions, which could affect correct boiler combustion.
This
draught stabiliser must be installed below the fume inspection plate to prevent any
leakage of combustion gases.
- It is recommended to connect each boiler to an independent chimney to avoid possible
revokes.
