ENERGA 80-50
Built-in fi res may solely be used in:
• Rooms with at least one outer door or window that can be opened;
• A suite of rooms connected directly or indirectly with each other with a collective
supply of air.
In the aforementioned cases, the capacity of the room(s) must be at least 4 m³ per kW
of nominal output.
Built-in fi res may only be constructed or moved into rooms where at least 360 m 3
combustion air per hour and per m
2
clear fi re opening can circulate. If there are any
other fi re-burning appliances in the same room, at least 540 m³ combustion air per hour
and per m² clear fi re opening must be in circulation.
Other appliances must have at least 1.6 m³ combustion air per hour, per total nominal
output in kW at a calculated pressure difference of 0.04 mbar with the ambient air.
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.
