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 WAVE 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 7 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 2 curves + linear sections isolated and non
isolated.
