Soot deposits
Even when there is only a small amount of soot buildup,
the heating surfaces become insulated and the firing ef-
ficiency falls.
A 1 mm thick layer of soot causes an increase in the
exhaust gas temperature of approx. 50 K (see diagram).
à Dust and dirt must be cleaned from the unit including
from the heat-exchanger, combustion chamber and
forced-air burner. Combustion residue in the com-
bustion chamber and in the heat-exchanger must be
removed.
à The V-belt tension and the motor mount must be
checked on a regular basis.
à Parts that wear out, e.g. flue gas brakes, oil nozzles,
oil filter inserts, seals etc. must be checked, cleaned
and replaced if necessary.
à Make sure to comply with waste gas emission limits
in accordance with regulations.
Maintenance and Service
The operator must have the unit checked and serviced
as necessary, at least once a year, by a representative
of the manufacturing company or another authorised in-
dividual in accordance with the operating conditions.
G Adjustments or maintenance work on the unit or
forced-air burner may only be performed by
authorised personnel!
G
Prior to doing any maintenance or repair work on
the unit, unplug it from the power supply. It is not
adequate to switch off the unit with the operating
switch!
Important Information on Servicing the Unit
à If the cleaning and burner adjustment intervals are
not observed, the guarantee becomes null and void.
à It is therefore absolutely necessary to keep records
that work has been performed by authorised person-
nel in addition to creating standard protocols.
à We recommend entering into a maintenance con-
tract for the regularly scheduled maintenance and
service work.
