Instructions for use and installation instructions
that the combustion air stream created by the fire 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 fitting regarding the
suitability and combustion air supply. DIN 18160 must be observed. DIN 18895 parts 1
and 3 also apply.
Built-in fires
may be fitted with an air pipe supplying air from outside (this is mandatory
in Germany). The air supply should have an opening of at least Ø125 cm and the air
pipe should be fitted with an adjustment valve; the position of the valve should be
visible from the outside.
The air supply in thus refreshes the air in the room and is also used in the combustion
process. As this air runs through the convection system, it is also referred to as ‘pre-
warmed combustion air’.
The casing / fireplace
The casing may not be directly connected to the built-in fire, but must be constructed
so that it is self-supporting; a mantle iron or lintel should be used for this. The
covering in the area must be of non-flammable materials of flame-retardant material
class A1. This includes bricks, cladding, ceramic tiles, metal or plasterwork,
Promatec and Nobranda.
The opening for incoming and outgoing air from the casing must be at least totally
900 cm². At least 200 cm² from the opening for incoming and outgoing air must not
be closable.
The ventilation of the casing/fireplace can be provided by grills, but this can also be
achieved by not building the fireplace right up to the ceiling (leaving a gap of 5 cm).
