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 BEAUTY 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 10 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
A – left ducting rear hot air flow;
B – room middle hot air flow from middle fan;
C – right ducting rear hot air flow;
a – ducting A local external thermostat;
b – stove room B external probe;
c – ducting C local external thermostat;
maximum and minimum hot air flow rate/speed DUCT A and C.
