The Different Configurations - Stuv 21 Installation Instructions Manual

The different configurations

4 possible configurations
– [photo 1] extension [a] for full
opening + upper outlet [b].
– [photo 2] cover plate [c] for
partial opening + upper outlet [b]:
recommended when the chimney
does not provide sufficient draught.
– [photo 3] extension [a] for full
opening + lower outlet [d]: for
example, to integrate the stove
into a former fireplace containing
a lintel.
– [photo 4] Cover plate [c] for partial
opening + lower outlet [d]: to
integrate the stove into a low space
with a flue.
The choice of smoke outlet (high
or low) and level of opening (full
or partial) depends on architectural
criteria (whether brickwork already
exists or needs to be built) and on
the draught conditions. Generally
speaking, a high outlet is more
complicated, but ensures better
draught than a low outlet. Full
opening is also more difficult but
enables the glass door to be opened
fully, whereas partial opening stops it
at mid-height but restricts the risk of
backdraught.
Please note :
No partial opening with the
21/105 SF.
