The existing open fireplace into which the fireplace cassette is to be
installed must correspond to the guidelines for the construction of
fireplaces and the regulations in DIN EN 13229.
The fitter must satisfy themselves as to what extent the open fire-
place corresponds to these requirements. If necessary, the fitter must
carry out any required corrective work.
It must be ensured that the flue pipes, exhaust gas collection cham-
ber and chimney are operationally safe and fireproof.
Open fireplaces that are retrofitted with a fireplace cassette must
have their own chimney.
Open fireplaces may only be installed in rooms and locations where
no danger results from their position and structural conditions.
The installation room must have sufficient combustion air flow.
The surface area of the installation room must be designed in such a
way and be large enough to ensure that the fireplace can be properly
operated.
FIREPLACE CASSETTES MUST BE INSTALLED BY SPE-
CIALIST FITTERS OR SPECIALIST COMPANIES.

Approval must be obtained from the heating inspector/chimney
sweep for your district before the cassette is installed.
The chimney must be swept, examined and tested for leaks.
Check whether the open fireplace is suitable for installing a fireplace
cassette.
Please note that the fireplace will be subjected to a higher level of
stress after the cassette has been installed.
The existing open fireplace will be reduced in size due to the installa-
tion of necessary thermal insulation coatings.
IMPORTANT: Take into account the following conditions when measuring up
for the fireplace cassette.
Shut-off dampers are to be completely opened in the exhaust gas
system and locked in place so that they cannot close. If required,
they are to be totally removed.
The combustion air feed pipes that lead to the fireplace must not be
closed. Ensure that there is sufficient combustion air (minimum 360
m³ per hour and m² of the firebox opening).
