Overheated fallshaft
▀
There is a overheat protection located on the burners fallshaft.This
prevents back heat. If the protection has tripped, the power to
the feeder is cut. The cause of overheating is usually due to back
pressure in the boiler being too large, which in turn is usually due
to:
- The burner tube is full of ash.
- The boiler is full of ash.
- The chimney is too narrow.
- The burner is set on a too high effect.
Reset the protection by removing the cover plates of the boiler.
Then press the reset button (1), you should hear a "click" when it
is reset.
If the protection is tripped again we recommend you to contact
your installer to look over the function and settings of the boiler.
Change of burner fan
▀
Cut the power to the boiler. Remove the cover plates needed. Unscrew the lid of the electrical
box (1) and remove the cable ties, loosen the cables for the igniter (2) and the fan (3).
Unscrew the four hexagon socket screws (size 2.5) and remove the fan (4). The cable for the
igniter is pulled through the fan. Mount the new fan in reverse order.
After a change of burner fan, measure the flue gases as you might have to tune the burner
slightly due to fans having some variations in speed.
