2.7
Electrical Connection
The boiler is equipped for connection at 230 V~ 50 Hz.
The socket should have an appropriate
earth connection.
The terminal strip
J2
includes terminals for connecting the feed auger, whereas the terminal strip
J3
includes terminals for connecting the circulation pump of the boiler (
BC
) and the 3-way diverter valve
(or circulation pump) for the optional DHW circuit. The terminal strip
J7
includes terminals for
connecting a sensor for the optional DHW circuit. This sensor must be supplied by
DOMUSA TEKNIK
.
IMPORTANT: Before carrying out any work on the boiler's electrical installation, always
ensure it is disconnected from the mains.
2.8
Combustion product removal
BioClass iC 66
boiler is a 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 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 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 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.
