• removing ash, cleaning the pane, cleaning the combustion chamber, cleaning the flue;
• ash stored for a longer time in the drawer of the ash pan will cause chemical corrosion of the ash pan;
• periodical cleaning of the combustion chamber of the insert (the frequency of this activity depends
on the type and dampness of the wood used);
• cleaning cast iron elements, using a poker, sweeper, and a brush;
• cleaning the front pane with a preparation designed for that purpose (do not use it to clean cast iron
elements of the insert; do not use abrasive preparations, since these will scratch the pane);
• having the flue cleaned by a chimney sweep company, an activity that should be registered in the
specification certificate of the insert (the flue should be cleaned twice a year).
Attention: any maintenance activity may be done only when the fireplace insert is cold, additionally
using protective gloves.
6. Operating anomalies of the fireplace insert
When the fireplace insert is used, some anomalies may occur, indicating an irregularity in the opera-
tion of the fireplace. This may be due to external circumstances (e.g. natural environment) or the
insert having been installed improperly in violation of legal regulations in force or these instructions.
below are the most common causes of improper operation of the insert as well as troubleshooting
information.
a) receding smoke when the fireplace door is open – the door opened too abruptly (open the door
slowly):
- the rotary damper of the stack is closed (open the rotary damper);
- the room where the fireplace insert is installed is insufficiently supplied with air (ensure proper ven-
tilation in the room or supply air to the combustion chamber, as indicated by these instructions);
- insufficient air supply to the room in where firepaces is installed (provide adequate ventilation in
the room or bring air into the combustion chamber in accordance with the guidelinescause of this
manual);
- atmospheric conditions;
- chimney draught is too weak (have the flue inspected by a chimney sweep).
b) insufficient heating or the fire going out:
- small amount of fuel in the firebox (load the firebox with fuel, as presented in these instructions);
- the wood burnt is too damp (use wood of a dampness of up to 20%);
- chimney draught is too weak (have the flue inspected by a chimney sweep).
c) insufficient heating despite good combustion in the firebox:
- lean wood (use the wood recommended in these instructions);
- the wood burnt is too damp (use wood of a dampness of up to 20%);
- wood split into very thin chunks.
d) The fireplace insert pane is excessively dirty:
- the burning is not intense (frequent, small flames are not recommended; use only dry wood as fuel);
- use of coniferous and resinous wood as fuel (use broad-leaved wood as fuel, as described in the
instructions for the fireplace insert).
e) proper operation of the insert may be disrupted by atmospheric conditions (air humidity, fog,
wind, atmospheric pressure) and sometimes by nearby high structures. in the event of recurring
problems, it is advisable to obtain an expert opinion from a chimney sweep company or to use a
chimney cap (e.g. a tallboy).
Attention! slow burning generates an excess of combustion products (carbon black and water
vapour), creating creosote in the chimney flue, which may ignite. abrupt combustion may ensue in
the chimney flue (a large flame and high temperature), described as the chimney fire.
in case of such a phenomenon:
• close the rotary damper of the insert stack, the openings in the drawer of the ash pan, and the cold
air inlet;
• check that the front door of the insert is property closed;
• notify the fire brigade.
