Do Not Install The Fireplace In The Following Locations; Combustion Air Supply - Spartherm Premium V-FD-87h Aufbauanleitung

3.3 DO NOT INSTALL THE FIREPLACE IN THE FOL-
LOWING LOCATIONS
• in stairways, unless they are in residential buildings with two or fewer
flats.
• in hallways with general access.
• in garages.
• in rooms in which highly combustible or potentially explosive substances
or mixtures are processed, stored or manufactured in quantities that
would be hazardous in the event of ignition or explosion
• fireplace systems in rooms or flats that are ventilated through ventila-
tion systems or warm air heating through the use of fans, unless the
safe operation of the fireplace system is ensured.

3.4 Combustion air supply

Fireplace systems may only be installed in rooms with at least one door or
window opening to the outside of the building or in rooms, directly or indi-
rectly "linked with other rooms by the same combustion air". When install-
ing fireplaces in apartments or building units with multiple living quarters,
only the rooms in the same apartment or building unit are deemed to be
"linked by the same combustion air".
Fireplace systems may only be installed in the aforementioned rooms,
where the flow of combustion air is at least 360 m³ per hour for every m
door opening. If other fireplace systems are installed in the same installa-
tion room or in rooms that are joined to the installation room, according to
technical guidelines the fireplace systems must be provided with at least
540 m³ of combustion air per hour for every m2 door opening, and the
other types of fireplace systems must have at least 1.6 m³ of combustion
air per hour and per kW total nominal heat output at a calculated pressure
difference of 0.04 mbar with respect to atmospheric conditions. An air flow
velocity of around 0.15 m/s is generally used for calculating supply pipe
diameter. For a fireplace insert with a door size of 51x60 cm, a feed pipe
cross-sectional area of 175 cm² is required, i.e. a supply pipe diameter of
ca. 15 cm.
Where the volume of combustion air at the installation is inadequate (e.g.,
in houses with ventilation systems), a combustion air feed pipe must be
connected to the appliance. The combustion air feed pipe is designed to
supply the appliance with air from another room. ( The source room must
have a plentiful supply of air. If in doubt, consult a local expert and refer to
the FeuVo and DIN 18896).
A shut-off valve must be installed, where the combustion air feed pipe runs
outside the building. It must be possible to easily determine the shut-off
valve setting. This arrangement allows the feed pipe to be isolated, in
order to guard against the formation of condensation. The pipe must be
positioned, so that any condensation formed can run out of the pipe and
water or other foreign substances cannot get in.
NOTE
In the interests of providing adequate amounts of combustion air, the Jan-
uary 1980 issue of Furnace Regulations for instructions on system design
and the May 1998 issue of Furnace Regulations for examples of working
2
systems should be consulted. These can be found in Institute of Building
Technology Report No. 3/1980, 17th. Ann. Issue (see also the commentary
to DIN 18895).
