19 BIOCLASS iC 150
3.5 Combustion product removal
The BioClass boiler is a BIOCLASS iC 150 biomass boiler and it is essential for it to be 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 in 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 independently located, with a separate flue for each boiler.
•
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 system.
•
It is recommended that a draught stabiliser be installed to prevent any pressure drop
variations in the flue due to atmospheric conditions, which could affect correct boiler
combustion.
