AIR SUPPLY
For proper combustion it is necessary to renew the air in the room with fresh air coming through an air opening in the
wall through the grate at door of the boiler room or through the open window. These solutions ensure proper combustion
and proper operation of the boiler.
The opening for air supply should be protected with the mesh against rain, wind and insects.
The opening should be located on the outer wall of the room where the pellet boiler is installed.
The UNI Standard 10683 prohibits bringing air from the warehouse for storing flammable materials or from the premises
where there is a risk of fire.
If there are other combustion devices in the room, it is necessary to ensure a sufficient amount of air for proper
combustion within all existing devices, as well as to take into account all the technical characteristics of all ventilation
systems built-in in the boiler room.
Figure 8.
CONNECTION TO THE POWER SUPPLY
The device must be connected to the electricity grid. Our boilers are equipped with an electrical cable for medium
temperature. If the power cord is damaged it must be replaced, so contact our authorized service. Before starting work on
the electrical connection, care should be taken about the following:

Make sure that the characteristics of electrical installations comply with data on the boiler.

The flue gas exhaust system should be grounded in accordance with local regulations. (Grounding is required by
law.)

The power cord must not in any case be exposed to the ambient temperature of over 80˚C. If you want to
connect the boiler directly to the power grid, it is necessary to 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
earth conductor must be disconnected in the switch. The double pole switch must remain accessible after
finishing the installation of the boiler.
Connecting to the power supply
The pellet boiler should be connected to the electricity grid. The electrical connection cable is 3 m long, white in colour
and marked "220 V". Another connection cable is black, intended for connection of the circulation pump and marked
"Pump".
