Ensure a supply of air through the front of the burner but
avoid serious draughts.
Bottom aeration, even correctly dimensioned but positioned to the
rear of the boiler close to the draught diverter, may turn out to be
totally ineffective.
Incoming air is directly drawn in by the draught cut off without
reaching the burner.
An indirect air inlet through descending conduits presenting serious
airotic losses of load or input of meteorological conditions influencing
their draw should be avoided.
