Installation Of The Fireplace Cassette Into An Existing Fireplace - Spartherm XS 500 Installation And Operating Instructions Manual

2.15 Installation of the fireplace cassette into an
 Clean the firebox in the existing open fireplace thoroughly.
 Installation measures that bring about any restriction to the open
fireplace 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 -
calculated according to DIN EN 13229 - must be adhered to if the ex-
isting 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 cham-
ber. These critical areas must be constructed in such a way that soot
particles and flying ash can fall back into the firebox. This can be
achieved using deflectors or through corresponding lining with fire-
clay or refractory 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 ac-
cording to the individual country.
Attention: The fireplace cassette has not yet been fitted at this stage!
The required process steps for connecting the flexible exhaust gas
flue system to the exhaust gas socket on the fireplace cassette are
listed here:
- Dismantle the deflector plate (also see 2.22) by firstly removing
both of the side blocks of the firebox lining.
- Now remove the exhaust gas socket from the fireplace cassette
and connect this socket to the flexible exhaust gas flue pipe in-
side 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 pushed into any gaps.
- Then insert the complete fireplace cassette into the open fire-
place and reach through the open exhaust gas connection on the
cassette into the fireplace. Pull the exhaust gas socket onto the
rear wall of the cassette and fix it in place with two screws and
nuts via the firebox.
 Replace the deflector plate and straighten up the fireplace cassette
where necessary (see 2.16).
 After the fireplace cassette has been installed, the space between the
outer casing of the cassette and the walls of the open fireplace must
be tightly filled in.
