4.1.3  Air intake and inlet cone service

1. 

Switch off the main current, disconnect the 7-pole Euro plug from the 

burner and turn off the gas.

2. 

Loosen the screw assembling the front piece of the burner and the fan 

housing, but not more than that the fan housing can be removed from 

the front piece. Disconnect the cables to the multiblock.

3. 

Remove the fan housing from the front piece and pull it backwards 

until the cables to the ignition electrode and ionisation electrode can be 

loosened.

4. 

Disconnect the cable to the damper motor, the cable to the second-

stage thermostat.

5. 

Unscrew the cover of the 4-pole Euro plug to the second-stage 

thermostat and remove it from its attachment.

6. 

Loosen the screws (K) holding the air switch, 2 pcs. Remove the air 

switch.

7. 

Loosen the screws (I) holding the air intake, 3 pcs.

8. 

Remove the air intake.

9. 

Loosen the screw (J) holding the inlet cone and note the inlet cone 

position.

10.  Remove the inlet cone from the fan housing.

11.  Check the function and appearance of the different components in the 

air regulation. Clean and replace the components as needed.

12.  Assemble the burner. Be careful when installing the inlet cone - install it 

in the same position as it was before being removed.

13.  Fit the O-ring in the groove between the fan housing and inlet cone. 

Ensure that it is properly located in the groove and is not damaged 

when the air intake is fitted.

14.  Connect the 4-pole Euro plug to the second-stage thermostat.

15.  Connect the connectors to the damper motor, second-stage 

thermostat.

16.  Install the 7-pole Euro plug, switch on the main current and open the gas
