Electrical Connection - Cola CHARME CANALIZZABILE Installations-, Bedienungs- Und Wartungsanleitung

2.6 Hot air ducting
The CHARME ductable model has two rear connections of 80 mm
external diam. for ducting the hot air flows generated by two
centrifugal fans inside the stove in heat exchange with the side walls
of the combustion chamber.
To create the ducting system:
- use pipes with internal diam. of 80 mm able to resist temperatures
of at least 150°C;
- use pipes that are smooth inside, insulated or isolated;
- reduce, as far as possible, the ducting path and the single pipe
section must not be longer than 6 m;
- avoid constrictions or section reductions, tight bends and
downsloping sections.
Given below is an example of a ducting system in a residential
building and graph of the temperature curve depending on the length
of the ducting pipe outside the stove, insulated and non-insulated in
the condition of hot air .
The canalisation flows A and B can be also regulated by specific
regulators available on demand.
The diagrams below have been obtained at the manufacturer's lab
through real tests under following conditions:
room temperature 20°C;
stove at operating speed 5, fans at 5;
ventilation ducts wit 1 curve + 1 linear section non isolated.

2.7 Electrical connection

Connect one end of the power cable to the rear socket of the stove, and the other to the wall socket.
The voltage supplied by the system must match that specified on the stove dataplate and in the technical data
section of this manual.
During stove idle periods it is advisable to remove the power cable.
- Make sure the electrical system is equipped with an earth and differential switch in accordance with the
current Regulations.
- The power cable must never touch the stove exhaust pipe.
