AIR SUPPLY
The combustion air must be supplied to the room with the boiler. The room must be continuously aired.
The fresh air opening must be at the bottom of the room and must let in the air.
A) Combustion air supply by pipeline through basements. This connection option preheats the combustion air, which is
useful for good and clean combustion. Installation of pipelines in the basement is simple.
B) Combustion air supply through basements. The combustion air is preheated. The basement space must be separated
from the ventilation system of the house and open to the outside. Avoid high levels of dust and moisture.
V) Combustion air supply from above. Air supply from above can only be performed with tested flue systems.
In this case, you must calculate the dimensioning of the flue!
D) Combustion air supply directly from outside. If the air is supplied directly through the outer wall, the combustion air is
only slightly preheated, which is unfavorable for clean combustion. In this case, there is also a risk of condensation!
NOTE: We do not recommend these versions of the air supply! However, if you use these options, consult a qualified
professional.
The room with the heating appliance must have a sufficient supply of fresh air. If the windows and doors are hermetically
sealed or there are air extracting devices such as a hoods, hair dryers, fans, etc. located in the room with the boiler,
combustion air (fresh air) must be supplied from outside. In any case, this should be discussed with the competent
chimneysweeper before installing the boiler.

CONNECTION TO THE POWER SUPPLY
The appliance must be connected to the power grid. Our boilers are equipped with an electrical cable for medium
temperatures. The power cable must be replaced if damaged, so contact our authorized service.
Before starting the works on the electrical connection, take care of the following:
Whether the electrical installation characteristics correspond to the information on the boiler.
The flue gas exhaust must be earthed in accordance with local regulations. (The earthing is required by law.)
The power cord must not in any case be exposed to the temperatures of over 80˚C. If you want to connect the boiler
directly to the power grid, you must install a two-pole switch, suitable for the mains voltage in accordance with the
applicable regulations, with contact spacing of at least 3 mm. The green-yellow earthing conductor must be
disconnected in the switch. The two-pole switch must remain accessible after finishing the installation of the boiler.
Connection to the power supply
The pellet boiler should be connected to the power grid. The power connection cable is 3 m long, white in color and
marked “220 V”. The other connection cable is black, intended for connection of the circulation pump and marked “Pump”.
