Masonry Work For Walls Needing Protection; Expansion Joint Between The Casing And The Fireplace Cassette; Combustion Chamber Design - Spartherm XS 500 Installation And Operating Instructions Manual

3.6.1 MASONRY WORK FOR WALLS NEEDING
PROTECTION
• When installing the open fireplace on walls needing protection then
masonry work is required. The masonry work must project at least 200
mm above the flue pipes.
• The masonry work (100 mm) can be dispensed with when the build-
ing's alls are:
- At least 115 mm thick
- Made of non-combustible construction components
- Not made of load-bearing concrete or reinforced concrete
• The masonry work can be completed in a conventional way e.g. using
bricks or can also be constructed out of so-called "thermal insulation
panels" so that the overall construction depth - consisting of masonry
work and thermal insulation - can be significantly reduced. Alternatively,
the masonry work and the insulation can be completed using suitable
insulation materials, see 3.6. This will enable the overall thickness to be
reduced significantly.
3.7 EXPANSION JOINT BETWEEN THE CASING AND
THE FIREPLACE CASSETTE
There must be no direct connection between the fireplace cassette and the
casing. An expansion joint is to be fitted that should be connected using e.g.
a sealing strip. Please note that there must be a minimum distance of 6 mm
between the door frame and the fireplace apron to enable the firebox door
to be dismantled if required.
