WARNINGS TO AVOID BURNOUT OR BAD COMBUSTION OF THE BURNER
– When the burner is stopped, the smoke pipe must be opened and effect a natural draught in
the combustion chamber. If the smoke pipe is closed, the burner must be drawn back till the
extraction of blast tube from the furnace. Before operating in this way take the voltage off.
– The place, where the burner works, must have same openings suitable for the passage of air
necessary for combustion. To be sure about this, you have to control the smoke number of
exhaust gas with all the windows and doors closed.
– If in the place, where the burner works, there are air-breathings, check the existence of air-
input openings with dimensions suitable for the necessary air-exchange. In any case check
that, when the burner is stopped, the air-breathings do not draw warm smokes from pipes
through the burner.
