COMMENT
For guidance on realizing a sufficient supply of combustion air, see the the German
Sample Combustion Ordinance (May 1998 version) and the example of the standard
operating procedure for the German Sample Combustion Ordinance (January 1980
version); the examples were published in the Institute for Construction Technology
Bulletin no. 3/1980, 17th year (also see comments on DIN 18895).
3.5. COMBUSTION AIR FLUE
As per the specification of the German federal state construction ordinance
that corresponds to § 37, para. 2 of the sample construction ordinance,
combustion air flues in buildings with more than two full storeys and com-
bustion air flues that bridge firewalls must be constructed to prevent them
from transferring fire and smoke to other storeys or fire zones.
COMMENT
For information on how to comply with the above-mentioned specifications,
see the fire inspection guidelines for the fire prevention requirements of
ventilation systems (draft) – January 1984 version.
4. CUTOFF DEVICE IN THE VENT
Open fireplaces with SPARTHERM fireplace inserts may have a cutoff device in
the vent. The cutoff device may not hinder the inspection and cleaning of con-
necting pieces and may not close automatically. The position the cutoff device
is in must be obvious from the outside, e.g. from the position of the operating
handle. Cutoff devices may only be installed in the exhaust manifold, the flue
gas neck tube or in the connecting piece. Instead of cutoff devices, fireplace
inserts with combustion chamber doors can have throttle devices.
4.1. THROTTLE DEVICE
Throttle devices may only be installed in the flue gas neck tube or in
the connecting piece. Throttle devices have to be easy to operate. Their
openings have to be like the segment or section of a circle whose total
area is not less than 3 % of the cross section area but has a size of at least
20 cm

. The position the throttle device is in has to be obvious from the
setting of the operating handle.
5. FIRE PREVENTION IN FRONT OF THE
COMBUSTION CHAMBER OPENING
5.1. FLOORS
In front of the firemouths of fireplaces with closed combustion chambers,
floors made of combustible construction materials have to be protected by
a covering of noncombustible construction materials. The covering has to
protrude beyond the firemouth by at least 50 cm at the front and at least
30 cm at the sides.
In front of fireplaces that can be operated open, floors made of combustible
construction material must be protected at the front by a covering of non-
combustible construction material equal to the height of the combustion
chamber base or the firedog above the floor plus 30 cm (but at least 50 cm),
and at the sides equal to the height of the combustion chamber base or the
firedog above the floor plus 20 cm (but at least 30 cm). If a log guard with
a height of at least 10 cm has been installed, fire protection of 50 cm at the
front and 30 cm at the sides is sufficient.
The non-combustible covering can be made of ceramic (e.g. tiles), natural
stone or other mineral construction materials (e.g. marble, granite, etc.),
metal with a thickness of at least 1 mm or suitably treated glass. The covering
must be fastened in a manner that makes it impossible to be pushed away.
If a log guard (not included) with a height of at least 10 cm has been
installed, the minimum distances listed above are sufficient and can be
measured from the log guard.
