Burner chamber and heat exchanger are cleaned in
the following way (fig. 11):
- Remove cover plates above the burner and on the
left or right hand side.
- Remove the inspection cover (2) from the heat
exchanger.
- Draw out the turbulators through the upper heat
exchanger pipe (1).
- If there is no visible dirt in the heat exchanger the unit
is reassembled as described above, but in reverse
order. New packing should always be used when
reassembling the unit.
- If it is necessary to clean the heat exchanger the
service cover (3) above the burner should be removed
and the burner chamber (4) be checked for dirt.
- Then every heat exchanger tube (1/7) is cleaned by
means of a round wire brush. The inspection cover to
the flue gas collector (6) is removed and the soot is
vacuumed out through the opening in the collector.
- The soot from the lower heat exchanger tubes is
vacuumed out through the burner chamber (4) by
means of a vacuum cleaner.
- Then the turbulators are cleaned and pushed back
into the upper and anterior heat exchanger tubes (1/
7) and the unit is reassembled in reverse order.
4.3 Fan and V-belt
In order to be able to check the fan and the V-belt the
air intake grill in the right side must be removed.
The fan runner should be checked for dirt every 6
months and, if necessary, tightened up.
Motors up to 4 kW should be adjusted so that the V-
belt is depressed 10-12 mm. On larger motors the
depression should be about 15 mm.
4.4 Further Components
All other components in the DV 45-300 units need no
service.
The burner should be checked in accordance with the
instructions of the burner supplier.
