ENERGA 70-55 TUNNEL
Built-in fi res must not be used in:
• Staircases, except in buildings with no more than two apartments.
• Entrances providing general access.
• Rooms in which highly infl ammable or explosive substances are processed or
manufactured.
• Garages;
• Rooms or apartments with air conditioning or convection heating provided by fans,
unless it can be guaranteed that they will not interfere with the working of the fi re.
This is under the following conditions:
° the installation merely circulates air around the room;
° the installation has suffi cient safety provisions preventing the possibility of
spontaneous and automatic underpressure being created in the room in which the
fi re is situated;
° that the combustion air stream created by the fi re and the volume streams of the
extraction installations in the room and adjoining rooms connected by de-aeration
connections do not create underpressure greater than 0.04 mbar. This must also
be guaranteed if easily accessible air-conditioning equipment is moved or removed
from the room.
Provision of combustion and convection air
The local chimney sweep/authorities must be consulted prior to fi tting regarding the
suitability and combustion air supply. DIN 18160 must be observed. DIN 18895 parts 1
and 3 also apply.
The air, which is piped in through a grill in the wall, ensures that the air in the room is
refreshed and is also used for the combustion process.
The combustion air is sucked in through the grill in the chimney breast and through the
opening underneath, or at the side of the appliance. Because some of this air passes
through the chimney breast, it can be referred to as pre-heated combustion air.
The built-in appliance can also be fi tted with an air duct which draws the combustion air
directly from outside.
The air intake must have a opening of at least Ø125 mm. If required, the air pipe can be
fi tted with a control damper. In this case, the position of the damper must be visible from
the outside. The use of a direct combustion air intake is strongly advised if the appliance
is fi tted with a convection set.
