5.2 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.
5.3 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 ope-ning 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.
