Make sure that all of the flue system is gas-tight,
Insulate any non-insulated pipes with ceramic insulation wool. Refer to section
the insulating material requirements.
Warning:
Make sure to always remove a break out plate from the combustion air inlet
box. Make sure to do this also when the appliance has combustion air supply
from the installation room.
Note:
•
It is possible to install the appliance without external air supply and take
combustion air from the installation room. If so, make sure the combustion
air inlet on the appliance is not blocked and the ventilation air inlets are
according the requirements. Refer to section
ventilation air openings.
•
The appliance is a room-sealed appliance when combustion air comes
from the outer side of the building through a flexible pipe that is connected
to one of these:
•
the combustion air inlet under the appliance.
•
the combustion air inlet on the combustion air box.
•
the combustion air inlet on the convection ventilator / combustion air
box.
•
If not connected to one of these three possibilities, the appliance is not a
room-sealed appliance and the data for leak tightness as given in section
11
are not valid.
•
It is strongly recommended to install a valve in the external combustion air
supply pipe, to avoid debris in the pipe and to avoid water vapor
condensation in the appliance when not in use.
Make a hole in the outer wall or floor with a diameter of minimum 125 mm.
Install a grate in the hole in the outer wall. A grate is not needed when the
combustion air supply comes from the crawl space under the floor.
Put a 125 mm flexible aluminum pipe
over the combustion air supply
connector
Secure the connection with a clamp.
Connect the other end of the flexible
aluminum pipe with the hole in the
