4.1  INSTALLATION OF THE FIREPLACE CASSETTE 

INTO AN EXISTING FIREPLACE

•  Clean the firebox in the existing open fireplace thoroughly.
•  Installation measures that bring about any restriction to the open fire-

place and reduce safety are not permitted.

•  Check whether the flooring of the existing fireplace is level. Slight 

unevenness can be balanced out later via the adjustable feet using an 
Allen key.

•  The prescribed minimum thermal insulation for the whole fireplace - cal-

culated according to DIN EN 13229 - must be adhered to if the existing 
open fireplace was not expertly constructed.

•  In order to prevent fires and deflagration, it is important to ensure that 

there are no dangerous deposits in the exhaust gas collection chamber. 
These critical areas must be constructed in such a way that soot parti-
cles and flying ash can fall back into the firebox. This can be achieved 
using deflectors or through corresponding lining with fire-clay or refrac-
tory concrete. Access is made possible through the cleaning openings.

•  Install the exhaust gas flue system in the existing chimney. This must 

be a flexible system according to DIN EN 1856-T2 but it may vary from 
country to country. 

Attention:

 The fireplace cassette has not yet been 

fitted at this stage! The required process steps for connecting the flex-
ible exhaust gas flue system to the exhaust gas socket on the fireplace 
cassette are listed here: 

-  Dismantle the deflector plate by firstly removing both of the side blocks 

of the firebox lining.

-  Loosen the two screws securing the exhaust gas connection and place 

it laterally into the combustion chamber (Fig. 7).

  -  Now remove the exhaust gas socket from the fireplace cassette and 

connect this socket to the flexible exhaust gas pipe inside the open 
fireplace. The linear measurement of the flexible exhaust gas pipe 
should be the actual length required so that the flexible pipe cannot be
