8. CONNECTION TO THE CHIMNEY
- Before connecting the fireplace insert to the chimney, check the size and condition of the
chimney (according to the DIN 18160 directives and standards). The correct operation of the
chimney according to DIN EN 13384 must be signed by legal authority. When making the
chimney calculations, you must include the parameters of the fireplace insert. When the door
is open (when adding wood) a safer quantity of air and combustion gases are taken away than
during normal operation.
- The flue channels must not be reduced to smaller diameters.
- More than one heat source may be connected to one chimney only if the heat source is
equipped with self-closing door mechanism and is certified according to EN 13229 A1.
Consequently, the calculation must be according to the standard DIN EN 13384, paragraph 2.
- Follow standards EN 73 4201, DIN 18160, DIN 18896 or the regulations for this type of consumer
appliance in the country of installation.
Connection / chimney flue
- The parts used for connections must be designed according to standard DIN EN 13384.
- A steel tube (chimney flue) designed for connecting the fireplace insert to the chimney and
containing a CE label can be used (the minimum thickness of the wall is 2 mm, for stainless
steel, 1 mm).
- If the draught in the chimney during the operation of fireplace insert is too high (more than
20Pa), it is recommended to install a chimney flap. In this case, make sure that:
- the flap is not automatically closed
- the flap has easy and clear control and the closed and open positions are marked
- the flap has holes in the net section of at least 3 % of the size of the total cross-section of the
flap, however, a minimum of 20 cm2.
9. AIR SUPPLY FOR BURNING
- The fireplace insert must only be operated in rooms with a sufficient supply of air for burning.
Equipment for extracting air (e.g. ventilation equipment, steam exhausting unit), which is
operated with the fireplace insert in one room, may interfere with the air supply into the fireplace
insert. In such an event, make sure that in the room no under-pressure occurs compared with
the outdoor environment.
- For problem-free operation, a suitable supply of air must flow into the flange in the lower part of
the insert (Fig. 6a):
