TO REMOVE/REPLACE THE DIVERTER
VALVE (Fig. 89)
Remove the front panel from the outer
casing, lower the instrument panel (sect.
7.16.2 & 3).
Remove lower gratin; (sect. 5.42).
Close the on/off valves for the heating
circuit and the hot water circuit. Drain the
boiler at drain point (Fig. 93) and drain hot
water from the lowest hot water tap and
drain point on DHW inlet cock (Fig. 46).
Unscrew the five nuts that connect the
diverter valve and pull it out from boiler
being careful not to damage the wires.
Pull off circlip securing microswitches to
diverter valve.
If replacing microswitch assembly use a
screw-driver to prise off the protective cover
of the microswitches.
Detach the wires that are connected to this.
Remember that they must subsequently be
reconnected to the same terminals (Fig. 94).
Replace in reverse order. Always use new
seals.
Fill the boiler as described in (sect. 6.4 & 5)
and check for leaks.
TO REMOVE/REPLACE THE CENTRAL
HEATING AND/OR HOT WATER CONTROL
THERMISTOR
Remove the front panel from the outer
casing (sect. 7.3) and lower the instrument
panel (sect. 7.162).
Remove left/right side of casing (sect. 5.4).
R e m o v e t h e w i r e s t h a t c o n n e c t t h e
thermistor (Fig. 81).
Close the on/off valves for the heating
circuit and the hot water circuit. Drain the
boiler at drain point (Fig. 93) and drain hot
water from the lowest hot water tap and
drain point on DHW inlet cock (Fig. 46).
