2.5 Brazier and baffle position check
Before lighting the stove make sure the brazier is in the correct position, i.e. fitted in the special slots. Also make
sure the top smoke baffle is properly fitted. A wrongly positioned baffle can result in malfunctioning and excessive
blackening of the glass.
At every stove lighting, check the correct position of the brazier on the brazier holder.
2.6 Hot air ducting
The ductable NETTUNO model has a top connection of external diam. 80 mm for ducting the flow of hot air
generated by the centrifugal fan inside the stove in heat exchange with the combustion chamber walls; this
connection can be turned 90° or 180° to direct the flow on the upper or lower part of the rear wall as required.
To create the ducting system:
- use pipes with a minimum 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 7 m;
- avoid constrictions or section reductions, tight bends and downsloping sections.
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 2 curves + linear sections isolated and non isolated.

2.7 Electrical connection
Connect one end of the power cable to the stove socket located on the front inside the hopper, 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 complies with the
regulations, and has an earth and differential switch in
conformity with the current Standards.
- The power cable must never touch the exhaust pipe
and the hot parts of the stove.
