17.4 - Cleaning the burner and the
primary exchanger, flue gas side
To properly clean the burner and the exchanger body (flue
gas side), proceed as follows (refer to figure 17-5 when not
otherwise specified):
1.- access the inner components following section 17.2;
2.- disassemble the fan burner unit following section 17.3;
4.- Run a cylindrical brush with nylon bristles inside
combustion chamber “H”
ATTENTION !!! DO NOT use metallic brushes. Only
use brushes with nylon or equivalent material bristles.
5.- Using an extractor, suction the unburnt residues inside
combustion chamber “H”;
6.- using the same extractor, suction the surface of the
burner and around the electrodes;
7.- reassemble the components in reverse order;
8.- open the gas cock;
9.- restore power.
10.- make sure there are no gas leaks between the
removed joints;
ATTENTION !!! Run the seal test exclusively with
a soap-based water solution. Using naked flames is
absolutely prohibited.
ATTENTION !!! Every time you clean the burner
and the main exchanger, you must first make sure heat
insulators “R” and “S” are in good condition (see figure
17-5). If necessary, replace them along with burner gasket
“T” (see figure 17-5), requesting the specific kit, code
