Once per heating season (preferably at the end of the season), the inspection cover must be removed
from
the appliance in order to remove the ash powder from the backflow preventor. The inspection cover
must
also be removed if you decide to use the top outlet instead of the one on the rear of the appliance
(see:
changing the fume outlet duct). To do this, grip the cover in the centre of the rib and tilt it upwards to lift
it
from its supports. Now you can also remove any ash powder deposited on the rear of the appliance
with a
vacuum cleaner.
Changing the fume outlet duct
If necessary, the fume outlet duct connection (factory setting: on rear), can also be altered to be
situated at
the top. A separate connector pipe (special attachment) is required for this. First remove the inspection
cover from the appliance (as described above). Then lift out the sunken cover in the cover plate and
remove
it through the opening of the inspection cover. Now insert the connector pipe through this opening and
reattach it to the same anchor point. Finally, insert the sunken cover through this opening and reattach
it to
the rear from the inside, and replace the inspection cover.
