HOPING YOU WILL BE SATISFIED WITH OUR PRO-
DUCT WE RECOMMEND YOU TO OBSERVE THESE
MAIN PRINCIPLES, IMPORTANT FOR THE SERVICE
LIFE AND PROPER FUNCTIONING OF THE BOILER
1. The installation, lighting of the test fire and training of the operators shall be performed by an
installation company trained by the manufacturer, which shall also fill in the boiler installati-
on record (page 28).
2. When using pellets for heating only use high-quality fuel with the diameter of 6 - 8 mm, made
of soft wood without bark and contaminants (white pellets).
3. During fuel combustion substances are produced that may damage the boiler body. Therefore,
the boiler must be equipped with Laddomat 21 or a thermo-regulation valve to maintain the mi-
nimum temperature of return water to the boiler of 65°C.
The operation temperature of the water in the boiler must be in the range of 80-90°C.
4. Each circulation pump in the system must be controlled by a separate thermostat so that the mi-
nimum temperature of return water can be guaranteed.
5. We recommend you to use the boiler in a system with one equalizing tank the volume of which should
be 500 - 100 l to achieve a higher service life of the pellet burner and lower fuel consumption.
CAUTION - If the boiler is equipped with Laddomat 21 or a hot-water thermo-regu-
lation valve - 60°C and an equalizing tank (see the attached diagrams), the boiler body
is subject to an extended guarantee of 36 months instead of 24 months. The guarantee
period of the other parts remains unchanged. If these principles are not observed, the
service life of the boiler body may be considerably reduced due to low-temperature
corrosion.
