Important
Following re-assembly, tap operation should be
checked at all settings. Ensure that red spot on knob
indicates correct position. (i.e. Check that spindle
adaptor has been replaced in correct position.)
3.8 GOVERNOR (NATURAL GAS ONLY)
This component is maintenance free. Check that blue
dust cap for vent is fitted and in good condition.
This protects the breather hole.
3.9 TO CLEAN BALL VALVE
Turn OFF mains water supply and drain steamer tank
at draw off tap.
Remove cistern lid.
Remove split pin from valve body.
Raise ball valve arm slightly and withdraw from valve
socket .
Unscrew cap at valve end and extract valve plug.
Clean all components with a soft rag. DO NOT USE
ABRASIVES.
Replace in reverse order and test soundness. Flush
out pipes to steaming oven and re-fit the tank.
3.10 ADJUSTING DOOR FIT
Prise off hinge covers with a plain screwdriver.
Shut door and assess if seal leaks or if hinge binding
is present.
Undo screws which secure hinges to door.
The serration in the hinges allows door to be adjusted
in or out to take up slack or prevent hinge bind.
The catch adjustment is accomodated by adding or
removing shims as appropriate.
3.11 IGNITION SYSTEM FAULTS
a) If spark igniter does not light pilot, check for a spark
and gas. If no spark is evident inspect electrode to
ensure the ceramic is not cracked and that igniter
lead is correctly located. Check insulation on lead
for damage also. Use an insulated screwdriver to
form a spark gap and check igniter operation (see
Figure 3).
Having established a spark, check gas flow to pilot
by lighting with a taper. If there is no gas, inspect
that pilot injector is not blocked. Carry out check
detailed in Section 2.5.3 of this document.
b) If spark ignites pilot but goes out when knob is
released, ensure FFD thermocouple connections
are tight and that pilot end of thermocouple is
enveloped in flame. If this does not result in
establishing pilot then replace thermocouple.
If there is still a fault then the gas valve will have
to replaced. See Section 3.8 for procedure.
