Ventilation
The ventilation circuit produces low noise levels with high performance
pressure and air output, in spite of the compact dimensions.
The air damper is easy to set; when fitted, it makes no difference to air
delivery.
Combustion Head
For the PRESS G24 - GV series of burners a special kit for increasing combustion
head length is available.
The choice of using it depends on the thickness of the front panel and the
type of boiler.
Depending on the type of generator, check that the penetration of the head
into the combustion chamber is correct.
The internal position of the combustion head can easily be adjusted to the
maximum defined output by adjusting a screw fixed to the flange.
