Combustion Air Piping; Exhaust Circuit Shut-Off Device; Throttling Device; Fire Protection On / In The Fireplace System - Spartherm Mini R1V51 Installation Instructions Manual

3.5 COMBUSTION AIR PIPING

In accordance with local regulations (Landesbauordnung) pursuant to Article
37 Paragraph 2 of the German Model Building Code, combustion air piping
crossing a fire wall in buildings with more than two fully-sized floors must
be installed such that smoke or fire cannot be transmitted to other floors or
fire compartments.
NOTE
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. EXHAUST CIRCUIT SHUT-OFF DEVICE

Fireplace systems with Spartherm fireplace inserts may have a cut-off
device in the vent. These devices must not be self-closing and must not be
positioned such as to prevent or hinder the inspection and cleaning of con-
necting pipework. The position of the shut-off device must be visible from
the outside, e.g., from the position of the operating handle. Shut-off devices
may only be installed in the exhaust manifold or collecting pipe, the flue
gas pipe stub or the pipeline connecting piece. Instead of cut-off devices,
fireplace inserts with combustion chamber doors can have throttle devices.

4.1 THROTTLING DEVICE

Throttling devices may only be installed in the flue gas pipe stub or pipeline
connecting piece. Throttling devices must be easy to operate. They should
have cross-sectional areas at the pipe of at least 20 cm² and not less than
3% of connecting pipe cross-sectional area. The throttling device setting
must be readily discernible at the operating handle.
5. FIRE PROTECTION ON / IN THE FIRE-
PLACE SYSTEM

5.1 SPECIAL PRECAUTIONS FOR FIRE PROTECTION

5.1.1 FLOOR COVERINGS NEAR THE FIREPLACE

With a floor covering that is not fireproof made from combustible materials
(e.g., carpet, parquet, etc.), a fireproof spark protection covering made from
non-combustible material (e.g., respectively loadable glass, natural stone,
glazed tiles, tiles, marble, granite or other mineral construction materials)
must be installed. If this material is metal, it must have a minimum thick-
ness of 1 mm.
The flooring must be fastened down and secured against sidewards move-
ment. The spark-protection covering must be directed to the front, the
height of the combustion chamber base (fire board height) must be H plus
300 mm, and must have a minimum length of 500 mm.
If a log guard (not included) with a height of at least 10 cm is fitted, the
minimum distances listed above are sufficient and can be measured from
the log guard.
