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.
In models 5183 LH/RH doors fireplace insert to maintenance and serivicing works opening on
aside. Should be released lever lock service by raise the lever(1). The pins (2) must be
relased from lock.
After service we clouse the doors in the revers sequence. The pins (2) must enter to the lock
and we close the lock by pushing the lever (1) down.
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.
