BURNER START-UP CYCLE
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 extrac-
tion 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 nec-
essary 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.
