Description
Room-ventilated version.
Without down-draught diverter.
Flue gas discharge via the roof.
Air supply from the installation area.
The air inlet connection of the boiler must stay open.
The installation area must be vented to ensure sufficient air
supply. The vents must not be obstructed or shut off.
The IP rating of the boiler is lowered to IP20.
Important
Flush the heating system with a volume of water equivalent to at
least three times the volume of the system.
Flush the domestic hot water pipes with at least 20 times the
volume of the pipes.
Important
Due to the presence of an aluminium heat exchanger, suitable
chemicals and the correct use of these chemicals should be
discussed with specialist water treatment companies.
Carry out any welding work required at a safe distance from the boiler.
Before installing, check that the gas meter has sufficient capacity. Take
into account the consumption of all appliances. Notify the local energy
company if the gas meter has insufficient capacity.
We recommend installing a gas filter to prevent clogging of the gas
valve unit.
Important
The installer is responsible ensuring that the right type of flue
system is used and that the diameter and length are correct.
Always use connection materials, roof terminal and/or horizontal
flue terminal supplied by the same manufacturer. Consult the
manufacturer for compatibility details.
The use of flue systems from other manufacturers is allowed in
addition to the recommended manufacturers listed in this
manual. Use is only allowed when all our requirements are met
and the description of flue system C
is respected.
