19.6 Fan Unit
Disconnect the electrical leads from the fan.
To remove the fan, disconnect the 90º bend from
the top of the boiler
Disconnect the electrical leads and air pressure
switch connection tube from the fan, remove the
fan screws and withdraw fan from fan hood with
its 56º bend.
(Section 18.7)
Fit the replacement fan unit in reverse order and
reconnect the electrical leads and sensing tube.
19.7 Air pressure switch
The air pressure switch is located on the top of
the expansion vessel. (
Figure 34)
Remove the sensing tube and electrical
connections from the air pressure switch, noting
which tube is connected to which port.
Remove the air pressure switch by pulling
forward off its bracket.
Fit the replacement switch in reverse order of
removal.
19.8 Burner
Remove the burner assembly from the combustion
chamber as detailed in Section 18.7 retaining all
washers/gaskets for use on re-assembly.
Remove the manifold as shown in
Figure 31.
Fit the manifold with new burner injectors and
tighten, ensuring that the injector size, marked on
each injector is the same as stated in the ‘Technical
Data’ section for the type of gas being used.
Replace the burner bar and re-fit the burner blades
(replace any damaged seals as necessary) and
reassemble the boiler in reverse order.
Check gas soundness and boiler operation.
19.9 Printed circuit board (PCB)
Turn off and isolate the electrical supply.
Remove the interface cover by lifting the two
latches.
(Figure 36- 37)
Remove the electrical connections to the PCB by
pulling carefully, noting the locations of all the
terminals.
Release the screws securing the PCB to the control
panel and lift out the PCB.
Fit the replacement PCB in reverse order to
removal, ensuring that the PCB electrical
connections are fully pushed home.
Check and re-set as necessary the potentiometers
and dip switches to the same value as the old PCB.
WARNING!
Ensure that the earth lead is re-connected.
Note.
The replacement burner is supplied as component
parts and requires assembly on site.
