Room ventilation
All rooms require an openable window, or equivalent,
and some rooms will require a permanent vent as well.
The air for combustion is taken from the room air and
the exhaust gases are emitted directly into the room.
Good ventilation is essential for safe operation of your
appliance.
Rooms with doors and/or windows which open
directly to the outer environment
The doors and/or windows that open directly to the
outer environment must have a total ventilation
opening of the dimensions specified in the table below
which is based on the total gas power of the appliance
(total gas power consumption of the appliance is
shown in the technical specification table of this user
manual). If the doors and/or windows do not have a
total ventilation opening corresponding to the total gas
consumption of the appliance as specified in the table
below, then there must definitely be an additional fixed
ventilation opening in the room to ensure that the total
minimum ventilation requirements for the total gas
consumption of the appliance is achieved. The fixed
ventilation opening can include openings for existing
airbricks, extraction hood ducting opening dimension
etc.
