combustion chamber “H”
WARNING! DO NOT use a metal brush. Only use
a brush with bristles made of nylon or a similar material.
5.- using an extractor, suck up the unburnt residue found
inside the combustion chamber “H”;
6.- with the same extractor, clean the surface of the burner
and around the electrodes;
7.- reassemble the parts in reverse order;
8.- turn on the gas cock;
9.- restore the electric power supply.
10.- check that there are no gas leaks between the joints
that were removed;

exchanger is cleaned the good order of the heat insulation
devices “R” and “S” must be checked (see figure 18-5).
