General.
The appliance may only be set up in a room in which the location, architectural
construction and activity is not endangered by the presence of a fire. The surface on
which the appliance is to be placed must be correctly shaped and big enough to
accommodate the appliance safely (in compliance with DIN 18895, part 1).
When fitting, all local and/or national safety regulations must be followed closely,
particularly in rooms with walls/floors containing flammable material. If in doubt, consult
the fire prevention department of your local fire brigade and/or the architectural depart-
ment of your local authority.
Built-in fires 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 fires
may only be constructed or moved into rooms where at least
360 m

combustion air per hour and per m

clear fire opening can circulate. If there are
any other fire-burning appliances in the same room, at least 540 m³ combustion air per
hour and per m² clear fire 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 fires
must not be used in:
Staircases, except in buildings with no more than two apartments.
Entrances providing general access.
Rooms in which highly inflammable 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 fire.
This is under the following conditions:
the installation merely circulates air around the room;
the installation has sufficient safety provisions preventing the possibility of
spontaneous and automatic underpressure being created in the room in
which the fire is situated;
