Regulations To Be Observed; Chimney Design; Combustion Air Supply; External Combustion Air Connection - Konigshutte Vela Anleitung

Regulations to be observed

● Local and building law regulations
● The stove must be installed by a professional and
connected to the chimney. The specific national reg-
ulations for safe installation of the connector must be
complied with. The connecting piece used must pos-
sess an opening for cleaning.
● The stove must be regularly checked by a
professional.
The heating stove's fire door is self-closing; it is there-
fore approved for connection to chimneys with multiple
connections.

Chimney design

The chimney design is according to DIN EN 13384-1
and -2 or to the specific national regulations. The chim-
ney must comply with the temperature class T400.
Necessary data

● Waste air mass flow rate ............... 3,5 / 3,1 / 3,4 g/s
● Waste air temperature at
connection duct ........................... 322 / 336 / 290 °C
● Minimum delivery pressure at
nominal thermal output ...................... 12 / 12 / 11 Pa

Combustion air supply

It must be guaranteed that there is enough combustion
air available for the stove. For the proper function of the
stove, a necessary combustion air volume current of
15,6 m³/h must be considered.

External combustion air connection

By an external operating mode, the combustion air
can be added from outside through a leak-proof line or
through a supply duct in the chimney. Thus, speak with
your district chimney sweep master.
Due to energy saving reasons, the combustion air in-
let should be able to be blocked if the stove is not being
operated. This can occur through a shut-off valve in the
combustion air line or through the air slide valves on
the stove. If a shut-off valve is used, this must be clear-
ly identified with CLOSED/OPEN.
Through the shutoff, it is avoided that heat is removed
from the set-up room through the constant circulation
of cold combustion air and cold combustion air lines
may lead to an increased formation of condensation.
Attention:
The combustion air line may not be closed during
operation!
In order to feed the combustion air to the stove exter-
nally via a pipe instead of from the room in which it is in-
stalled, it is possible to screw a Ø 125 mm combustion
air pipe to the back of the stove or at the bottom. If the
combustion air pipe installed is longer than 3 m, calcu-
lations will have to be carried out to verify an adequate
supply of combustion air. At extremely low outdoor tem-
peratures, condensation can occur on the combustion
air duct. For this reason it must be insulated with a suit-
able insulating material. Observe the rules of the oven
and air heating construction craft.
Use the Olsberg combustion air pipes with sealing lip.
Attention:
Appliances with external combustion air connec-
tion are not suitable for concurrent operation with
ventilation systems, without a supplemental safe-
ty system.
