After completing the hollow chimney breast, slide on frames can be pushed
on and create a clean transition from the fireplace opening to the fireplace.
When installing the fireplace take care that sufficient space is considered
for mounting the slide on frame!
No cladding material may be mounted on silde on frames! A sup-
porting frame must be installed to carry the weight of the cladding.
Self-supporting frames are fixed to the fireplace and are suitable for direct
wall mounting. In doing so, the maximum weight load to be applied is
200 kg Depending on the combustion chamber type, you have the pos-
sibility to readjust the frame when installed in order to, e.g., compensate
settlements.
We recommend that insulation material, e.g., fibre glass ceramic or 2 mm
fibre glass paper is inserted between the self-supporting frame and the
body of the fireplace. This allows minor thermal expansion of the fireplace
insert to be compensated.
Hollow chimney breasts with self-supporting frames should always be cre-
ated with fibre glass grating / expansion joints in order to reduce the risk
of expansion cracks!
