your fingers during cleaning because the fingerprints on the window
panel harden as a result of temperature and they cannot be removed!

9.2. WINDOW PANEL DISMANTLING
To clean the window panel, combustion chamber or install
decorative items, it is required to remove the window panel(s). Below
you will find the removal instruction for window panels based on the
example of corner version of fireplace (with two window panels). In the
version with one window panel, the arrangement of strips is the same
as for the front window panel with an additional, second side strip. For
a version with three window panels: the second side window panel
should be installed in the same way as given below.
1. Remove all end caps of the base located around the
window panel.
2. In a model with three window panels: remove the front
window first, which is pressed from top by a hinged beam.
Pull it back and then shift the lock in direction given on the
picture to lock the beam in position, allowing removal of
the window panel. In a fireplace with one or two window
panels, you should first remove the side masking frames of
the front window panel. Description of side masking frames
removal is given in item 4.
3. The front window panel should be lifted first so as to its
bottom edge leaves the base and then the bottom part of
the window panel should be deflected outwards. In such
position, the window panel can be removed from the upper
block and out of the fireplace.

magnets. First catch the handle and pull the bottom part
back and then pull the upper part of the masking frame.
