Front view of the boiler inside: 

Disconnect the electric connections and the pressure pipes: 

(a)  Pressure pipe connecting the gas valve to the venturi (just included in models ADI CD 200 and higher). 
(c)  Motor fan: electric supply connection (in the higher part of the motor). 
(d)  Motor fan: control indicator PWM 
(e)  Ionization-ignition kit: ionization electrode cap, ignition electrode cap and ground connection cable. 
(f)   Gas valve: electric supply connection. 

 

Note: (a) has fast connections (by pressing the plastic ring you can remove the pipe).

 

 
Remove the ionization-ignition kit. 
 
If the gas connection has a two-pieces coupling, disconnect it.  
 
Disconnect the two flanges of the gas valve (each flange has Allen screws of 
4 mm). 
 
Remove the nuts/screws of the flange connecting the fan-burner group to the 
boiler heat exchanger. 
 
By rotating the assembly motor-fan, you will find: 

-

 

Two gaskets between the boiler heat exchanger and the burner flange 

-

 Burner 

flange 

-

 

Gasket between the burner flange and the fan plate 

-

 Fan 

plate. 

 
Consider the minimum free height between the highest level of the boiler and 
the ceiling in order to extract/rotate the burner (see paragraph “boilers 
room”).  
 
Note: in models ADI CD 325 to ADI CD 750 the fan-burner assembly is 
rotating forward; in models ADI CD 850 and ADI CD 950, the fan-burner group is rotating backward.
