date of the unit. they expire on the last day of a product's warranty period.
The warranty does not include:
- grate and glass;
- defects caused by mechanical forces, contamination, modifications, alterations, maintenance and
cleaning of the unit, accidents, chemical agents, weather (discolorations, etc.), inappropriate storage,
unauthorised repairs, transport with a forwarding company or by post, improper installation or ope-
ration of the unit.
warranty claims will be rejected in the cases above.
For all our inserts it is forbidden to use coal as a fuel. In each case firing coal invalidates the war-
ranty for the hearth. When reporting a warranty defect the customer is obliged to sign
a declaration that they have not burnt coal or any other unauthorised fuels in our insert.
If the use of the said fuels is suspected, the fireplace will be examined for the presence of unau-
thorised substances. If the examination shows that such substances have been used, the custo-
mer loses all warranty rights and is obliged to pay all costs related to the complaint (including
the cost of the examination). If another fuel is permitted, the relevant information will be inclu-
ded on the rating plate.
The customer can exercise their rights through:
- free repair or replacement of parts recognised by the manufacturer as defective;
- elimination of any other defects found in the unit;
- the concept of 'repair' does not include the actions described in the user manual (maintenance,
cleaning) which the user is obliged to take on their own;
- complaints raised within the warranty period will be processed by the manufacturer free of charge
within 14 days after the complaint is reported provided that once properly completed this warranty
card and if the card is not available, a receipt showing the purchase date of the product concerned, is
supplied together with the defective equipment.
The warranty card is valid if:
- it has been properly completed and shows the purchase date, seal and signature;
- the purchase date shown in the warranty card is the same as that shown on the receipt or a copy of
the invoice.
Automatic Air Supply System (ASDP) – Systemthe bimetal based, self-regulating thermostat auto-
matically controls the supply of air to the hearth, and consequently controls the combustion tempera-
ture inside the freestanding stove.
Before lighting the stove set the opening angle of the thermostat so as to ensure free air flow to the
hearth and open the air inlets in the door and on the stove front..
it is recommended to open the thermostat initially (through experimentation) at 60%; then you will
obtain an optimal combustion temperature for a 3,5 - 4kg large batch of wood. once the batch is lit
close the air inlets in the door and on the stove front. As the temperature in the fireplace is growing, the
thermostat starts to perform its function: while closing gradually, it reduces the amount of air in the
combustion chamber. when the optimal temperature of 300°c is reached, air supply is largely reduced,
resulting in the stove's temperature falling down until the minimum temperature necessary to mainta-
in the fire is achieved. when the temperature drops below 250°c, air supply starts to be automatically
opened and combustions becomes more intense once again. to obtain a higher combustion tempera-
ture, you should set a larger opening angle of the thermostat before lighting the stove.
when the thermostat is in place, you can reduce the amount of wood needed to burn by 30% as com-
pared with the stove without an automatic combustion control system. in addition to wood savings,
this solution improves the comfort of the stove's use; there is no need to keep checking and adjusting
air supply in the door and on the stove front to maintain proper combustion: the thermostat will do
this for you.
