3. To exhaust flue gasses, use only ø80, ø100 or ø120 flue pipes with silicone rubber bands
The maximum amount of flue pipes to connect the boiler to the chimney is as follows:
Tee - 1 piece
•
1000mm or 500mm straight pipes – 3m maximum
•
Elbow 90° - 1 to 2 pieces
•
In case two 90° elbows are used, the maximum straight flue pipe length is 2m.
Horizontally mounted flue pipes must not exceed 1m, with a mandatory 3-5% drop at the boiler.
At the end of flue pipes installation, there must be an insulated chimney.
The minimum chimney diameter is ø130.
4. Insulated chimney connected to the boiler must be cleaned prior to commissioning
The manufacturer is not liable for any malfunctions caused by the lack of chimney maintenance.
The minimum frequency for cleaning the chimney is once a year. With larger diameter chimneys, the frequency is
extended accordingly.
Small-sized, square-shaped chimneys interfere with regular boiler operation. A chimney connected to the boiler cannot
be connected to any other device (e.g. another boiler, a furnace, a heater or other heating devices).
The minimum height of the external insulated chimney is 3m from the connection point of the flue pipes.
5. Supply voltage should be stable at 230V ± 5% max
In case this requirement is not met and a periodic voltage drop or jump occurs, the manufacturer is not liable for any
boiler malfunctions.
6. Proper boiler positioning
Once the boiler is installed, the leveling feet must be adjusted.
The minimum clearance of the boiler to non-combustible and poorly
combustible materials must be 50cm, whereas its minimum clearance to
combustibles must be 100cm!
In case the flue pipes must pass through combustibles, such as wooden walls,
they must be properly insulated.
If the boiler is installed on a combustible floor, it is vital to make a
non-flammable hearth pad with dimensions larger than those of the boiler
(at least 20cm longer than the back and sides and at least 40cm longer than
the front of the boiler).
If any of the above conditions is not met, the boiler cannot be commissioned!
