7. WHAT TO DO IF... ...Do you do it yourself?
Problem
Cause
Corrective action
Chimney or smoke flue sealing
(malfunction, “false” air is being
added).
Contact a chimney sweep (ask them to check the
chimney). For example, new sealing for the chimney
door is needed. Adjust the positions of smoke pipes
or replace them if damaged.
Chimney effect bad or not
working
Ask the chimney or stove specialist technician for
inspection to find out the reason and the solution
(e.g. cleaning the chimney, remove the smoke flue
reduction elements, higher chimney, more air in the
room, etc.
The door of another heating
device connected to the same
chimney is open
Shut the door
Chimney cleaning holes are
open
Close the cleaning holes
Smoke flue elements or other
parts of the heating system are
dirty or clogged.
See 6.1.
Insufficient fresh air supply
See 4.7.
Worsened weather conditions
See 5.5.

Protective paint is being
hardened/ the stove is dirty,
dusty
Allow the paint hardening process finish – the smoke
and odour will disappear in a short time / while cold,
clean the device outside
Sometimes is difficult to find the
reason but, usually one of the
following is found: wrong type of
fuel, wrong adjustment of the
firing process, weak or
temporarily weak chimney effect,
door sealing loosen
Rule: Clean the door from time to time (depends on
the type of the fuel used), see
5.4.
. If coal cakes are used, the door needs cleaning
more often than with wood
Chimney effect is too low
See 4.
Too much fuel in the firing area
Only load correct quantity, see 2.1. and5.3.

8. FREQUENT PROBLEMS AND QUESTIONS
8.1. Cracked (released) fireclay (vermiculite) brick in the burning area
It is emphasised that cracked fireclay bricks do not lose their function unless they have fallen out, so
there is no reason to replace them while cracked only. In case of replace needed, order the
components at your sales representative or manufacturer’s address. Please specify the type and the
serial number and the fireclay ID number (see the Technical Card).
Procedure If you need to replace the side bricks, remove the upper partition or remove the fireclay
holders and take the damaged brick away. Sometimes, you need to remove the cast grate with
bricks at the bottom. For the installation, use the same procedure (reverse). Make sure you place the
components back in exact positions (follow the Technical Card).
Caution! Do not put the stove in operation if (even a part) of the lining within the burning area falls
out. There is danger of burning the construction through.
8.2. Broken glass
The door glass is made of special glass-ceramic material, characteristic with top heat resistance. Do
not use standard window glass!
Procedure: There is no need to dismount the whole door. You should only unscrew the holders and
remove the glass then easily. When you install the new piece, make sure the new glass is seated
evenly. The contact surface between the glass and the door must be provided with a sealing tape.
Do not replace the sealing tape if it is in good condition. Tighten the glass holders back slowly and
carefully to avoid cracking the new glass by excessive tension.
Caution! Some types of the fireplace insert are not provided with the sealing tape along the whole
perimeter.
8.3. Partitions to control the chimney effect
To clean the insert or replace fireclay (vermiculite) bricks, first remove the movable partitions (if
installed, see Technical Card) . This way, you make you way to the cleaning or replacement job.
Keep in mind that some types of the partitions are designed for holding the bricks at the position as
well. Make sure you do not tilt them or let them fall out and break. Install them back in their original
positions.
Disassembly: Lift the movable partition on one side a bit – this way, the other end is lowered. Move
the partition aside to allow taking it out of the device.
Assembly: Use the same procedure (reverse order). Insert the partition into the device and find the
previous position. Check the final position with the Technical Card!
