8.3 - Burner and fan removal
Proceed as follows to remove the burner fan unit (refer to
figure 8-3 when not differently specified):
1.- access the internal components following section 8.2;
2.- remove the air manifold (detail “C” in figure 6-3) rotating
it towards the outside of the appliance and then pulling it
towards the right (see figure 6-3);
3.- unscrew nut “C” from the valve “D”;
4.- disconnect the cables “B” and the detection cable from
the ignition and detection electrodes (details “15” and
“35” of figures 3-1, 3-2, 3-3 and 3-4);
5.- unscrew the four nuts “E”;
6.- extract the group “F” as per figure;
8.3.1 - Thermal insulations
Thermal insulations must be checked every year and replaced
if they are cracked or damaged. See Figures 8-3 where the
thermal insulations (items “G” and “H”) are showed assembled
in the burner and in the heat exchanger.
Once verified the condition of thermal insulation (see
Figure 8-3), if necessary, replace with spare parts kit,
following the instructions supplied with it. With the
thermal insulation must be replaced the burner gasket
“L” and the two gaskets of the electrodes.
8.4 - Gas burner and heat exchanger
outer surface cleaning procedure
To correctly clean the burner and the heat exchanger
(exhaust flue side), proceed as follows (refer to figure 8-3
when not differently specified):
1.- access the internal components following section 8.2;
2.- remove the burner unit following section 8.3;
3.- use a suction device to remove the unburned residues
present inside the combustion chamber;
4.- pass a cylindrical brush with plastic bristles inside the
combustion chamber
5.- use the same suction device on the surfaces of the
burner and around the electrodes;
6.- re-mount the components in reverse order;
7.- open the gas isolation valve;
8.- restore the electric power supply.
9.- check that there are no gas leaks on all joints;
CAUTION!!! Perform the leak test using a soap
solution. The use of flames is prohibited.
CAUTION!!! Every time you clean the burner and
the heat exchanger verify the good condition of thermal
insulation “G” and “H” (following section 8.3.1).
