PRODUCT PERFORMANCE CHECKS.
All our products undergo ITT TESTS carried out by a notied third party laboratory (system 3) and in accordance with Regulation (EU)
number 305/2011“Construction products”, according to standard EN 14785:2006 for household appliances and“Machinery Directive”EN
303-5 for boilers.
In the case of tests for any market surveillance or inspections by third parties, please consider the following warnings:
• To reach the declared performance levels, the product must perform an operating cycle of at least 15-20 hours beforehand.
• Set the average draught of the combustion fumes as specied in the“technical product features”table
• Thetypeofpelletsusedmustcomplywiththecurrent EN ISO 17225-2 class A1 regulation.Firpelletsare usually used for certication.
• The amount of thermal energy can vary according to the length and caloric value of the fuel. This may require some adjustments
(accessed from the user menu) to comply with the hourly consumption specied in the“technical product features”table. Using class
A1 pellets guarantees a caloric value that is likely to be close to that used in the product certication; the size of the pellet grains can
signicantly aect hourly fuel loading and consequently performance; it is therefore suggested to use pellets with a 6 mm diameter
and an average length of around 24 mm (avoid pellets that are too long or excessively crushed).
• Withwood-burningappliances,the fuel must complywith the currentEN ISO 17225-5 class A1regulation.Checkthe correct moisture
of the fuel, as it must be within the range of 12 - 20% (it is best if the moisture is close to 12%, as is normally used in certication). As
the fuel moisture increases, dierent combustion air settings are required, which are implemented from the combustion air register,
thereby modifying the mixture of primary and secondary air
• It is important to check the operation of devices that can aect performance (for example air fans or electric safety devices) in case
of damage due to handling.
• Nominal performance has been obtained by setting the maximum ame power and room ventilation in manual mode.
Performance at reduced power was achieved at minimum ame and ventilation power (P1 and V1) in manual mode.
The other conditions correspond to intermediate ventilation and power.
• If a “verication”mode is provided in the menu, set this function during the readings to ensure that no temperature modulation
occurs due to an incorrect setting of the operating parameters.
• Lastly, strictly comply with the sampling points specied in the regulations in terms of emissions as well as temperature
