ought to be cleaned. The connecting pipes ought to have cleaning holes, accessible through
grates or doors in the fireplace enclosure.
2.4.2 Fireplace insert glass pane
Both because of esthetical and operational reasons, particular attention ought to be paid to
the ceramic heat-resistant glass pane equipped with an air supply system to protect it against
contamination (so-called vitroceramic glass pane with an air curtain). The vitroceramic glass
pane with an air curtain requires periodic cleaning (every couple of days), depending on the
quality of fuel and usage of the insert. Special products may be used for cleaning the glass
pane, but it can also be cleaned with ash using a damp newspaper or a cloth.
CRACKING OF THE GLASS PANE: vitroceramic glass panes are resistant to the
temperature of
750ºC and they are resistant to thermal shocks. Cracking may only be caused
by a mechanical shock (impact, violent closing of the door, etc.).
2.4.3 Fireplace insert
Inspection and cleaning of the whole fireplace is required before each heating season. The
inspection ought to include disassembly of internal insert elements (ceramic panels,
deflector, etc.), cleaning from soot and ash
– especially the insert body surface under the
chamotte panels (accumulated creosote hinders the flow of heat which, in turn, reduces
heating efficiency of the insert). The condition of gaskets should also be checked; in case of
damage, replace gaskets with new ones remembering not to tension the cord excessively as
it will lose its flexibility and the gasket will not play its role. After thorough cleaning and visual
inspection of the insert interior, all checked elements may be fitted again, with particular
attention to correct fitting, i.e. keeping proper expansion distances. At the end of inspection,
grease movable elements of the insert, including the damper levers, closures of the door and
door lifting mechanism, if installed. To do that, a heat resistant lubricant should preferably be
used (recommended by the fireplace insert manufacturer); do not allow excess lubricant flow
out of the insert. Afterwards, the insert is ready for further use, but the whole system requires
some more work.
During the heating system, a system based on circulation of hot air handles very high
quantities of air carrying dust particles (
which, unfortunately, cannot be avoided in today’s
environment), which in time deposit inside the fireplace enclosure and on grates of
convection air as well as on blades of the air turbine. To keep the system operational,
maintain silent operation of the turbine and keep hygiene at home, thoroughly dust all the
above elements of the system using a brush and an ordinary vacuum cleaner.
2.4.4 Removal of ash
KFD ECO i90H fireplace inserts are not equipped with an ash grate or ash box. Ash from
combustion of wood accumulates on the furnace board. The combustion chamber ought to
be emptied regularly, leaving only a thin layer of ash required for improved conditions of
wood combustion.
Removed ash should be placed in a container with a lid, made from non-combustible
material. The container ought to be placed on a base made from fire resistant materials, at an
appropriate distance from any combustible materials, and allowed to cool down completely.
Due to safety reasons, at least once a year check cleanliness of the duct supplying outdoor
air (with particular focus on the air intake located outside the building). The chimney ought to
be cleaned regularly by a chimneysweep who should also check whether the fireplace
installation is constructed properly, inspect connection of the insert to the chimney as well as
ventilation.
