Cutoff Device In The Vent; Throttle Device; Fire Prevention In Front Of The Combustion; Floors - Spartherm Mini R1V 51 Notice D'utilisation

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 connecting pieces and may not close automatically.
The position the cutoff device is in must be obvious from the out-
side, 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 2 . 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 mate-
rials. 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 ma-
kes it impossible to be pushed away.
