5. MAINTENANCE
5.1 CLEANING
The device works better if all its parts are without combustion residuals, a clean device will be less
exposed to problems due to wear. Cleaning frequency depends on how much and how the device
is used, as well as combustible quality.
WARNING! All these operations must be done with cold cooker or thermal cooker.
5.2 CLEANING THE VISIBLE PARTS
Stainless steel parts have to be cleaned cold with neutral detersives or with a specific solution for
stainless steel in case of hard to remove dirt. Do not use at all abrasive sponges that may scratch
the surface. Dry with a soft rag, following the glazing wise.
In particular situations, after the installation or with the cooking of meals, an oxidised superficial
stratus may be generated, in particular on the inox stainless steel frame. Also in these situations,
an accurate cleaning will restore the state of the product as it was new. On request Rizzoli gives
specific products to clean stainless steel. For enamelled or painted parts, do not use abrasive or
aggressive solution and in case of stains pour some oil and wait while it absorbs the halo, then
clean with a soft rag. It is also recommended to avoid the use of solvents or denatured alcohol on
painted parts.
5.3 CLEANING THE CERAMIC COVERING (L 90 - LT 90)
The ceramic covering of the device must be cleaned only with cold cooker or thermal cooker using
a soft and dry rag and the suited products available on the market.
5.4 MAINTENANCE OF THE COMBUSTION CHAMBER SHEETS (LT 90 - ST 90)
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 emissions 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.
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.
