11.3 Electrode Setting
When removing or replacing the nozzle, move the
electrodes forward to avoid the risk of damage.
The electrodes are slackened by unscrewing the
brass post that passes from the electrode holder
out of the side of the burner. When work is
complete, ensure the electrodes are reset as
shown and secured by tightening the brass post.
11.4 Burner Start-Up Cycle
11.5 Air Damper Adjustment
The air damper is set in factory. This regulation is purely indicative. Each installation however,
has its own working conditions: actual nozzle output; positive or negative pressure in the
combustion chamber, the need of excess air, etc. All these conditions may require a different air
damper setting.
Air Damper (A) – 15/21 Burner Only
Air Damper (A)
– The main air damper can be set in
either of two positions. To set the positions of the
damper, proceed as follows: Remove the secondary
air damper (B) loosening the screws (1). Loosen the
screw (2) and rotate the main air damper (A) to the
required position. Retighten the screw (2) and put
back the secondary air damper (B).
Air Damper (B)
Air Damper (B)
– The purpose of
this damper is to perform a fine
tuning of the inlet air. Tuning of this
device is possible by turning the
screw (3).
