Perform visual inspection of burner
(4) and blower (2). Any dirt intrusions
from the air supply are typically blown
and burnt through the burner under
normal equipment use. In case of
more severe dirt accumulations, such
as construction dust, a careful
cleaning of the metal screen (5) must
be performed using a vacuum clea-
ner.
The surrounding seals (6) of the bur-
ner plate and the ceramic fiber seal
(7) must be checked for damages,
and must be replaced if necessary.
Check adjustment of electrodes (8).
Remove burner room insulation (10)
Rinse out heat exchanger (9) with
clean water (remove stubborn dirt
accumulations with a thin plastic
brush, then rinse).
Assemble new burner room insulation.
