Inside the combustion chamber of the wood fired
thermal cooker are placed some mobile steel
sheets that have a double function: they allow the
entrance of the secondary air after-combustion at
an optimal height for the reduction of the emis-
sions and they protect the integrity of the boiler
acting as protective shield between the flame and
the wall of the boiler.
Anytime it is necessary a deeper ash cleaning,
when the thermal cooker is cold it is possible to
remove these sheets. To do this, it is necessary to
remove the hotplate disc or the circles.

GRILL CLEANING
Every time you use the thermal cooker you have
to clean the wood carrying grill before, at least you
have to clean the more rough deposits: the holes
of the grill should not be obstructed. To make this
you can use the poker given together with the

FUME-CIRCUIT INSPECTION
In the thermal cookers with oven the combustion
fumes are forced to turn completely around the
oven. For this reason, the thermal cookers with
oven are endowed with an inspection door to
clean the fume-circuit. The cleaning must be done
Picture 39 - Fume-circuit inspection.
Then it is necessary to remove the plate in order
to have more space to do the operation. At this
point, remove the sheets starting from the sides of
the combustion chamber and last the ones placed
in the rear part, unhooking them from the pin and
unthreading them up.
To reassembly the sheets it is necessary to do the
reversal operation, paying attention to insert them
in the correct position and in the correct order,
placing in the first time the base and then hooking
them to the pin.
thermal cooker. If the grill is not well cleaned, the
flame could not be well feed and so you could ex-
perience an irregular combustion. If the grill is be-
ing removed, it must be placed in its housing with
the flat part turned upwards.
at least every six months of normal use, like for the
chimney sweeping: according to use, you could
have to make the cleaning more often. The inspec-
tion door is located under the oven door opening
