3.8 OVEN THERMOSTAT
Remove control knobs and fascia panel as
detailed in Section 3.2.1.
Remove hob fitments as detailed in Sections 3.2.2 and
3.2.3 as appropriate.
Undo thermocouple connection at thermostat rear.
Disconnect oven burner pipe.
From inside oven, release clips that secures thermostat
capillary to oven side wall. Undo fixings that secure
thermostat to manifold.
Remove thermostat by carefully feeding capillary and
phial through crown plate.
Replace all parts in reverse order. Renew manifold
gasket if necessary.
3.8.1 Thermostat Calibration
The thermostat should not be calibrated. If temperature is
outwith specified tolerances, replace thermostat and
return faulty thermostat to Falcon Quality Department.
3.9 OPEN TOP and SOLID TOP GAS TAPS
Note
Plugs and bodies are machined in pairs and are
therefore not interchangeable. Always clean one tap
at a time.
3.9.1 Service - Isolate from gas supply.
Remove control knobs and fascia panel as detailed
in Section 3.2.1.
Remove fixings from front of tap body. Withdraw spindle
and niting arrangement to allow plug to be eased out.
Clean gas tap plug with a soft rag and regrease using an
approved high temperature lubricant. Take care not to
over-grease as surplus may cause gasway blockage.
Replace parts in correct order and check gas tightness.
3.9.2 Removal – isolate from gas supply.
Remove control knobs and fascia panel as detailed
in Section 3.2.1.
Remove hob fitments as detailed in Sections 3.2.2 and
3.2.3 as appropriate.
Disconnect thermocouple connection at gas tap rear.
3.10 GOVERNOR (Natural Gas Models Only)
The governor supplied is maintenance free. Check
that blue dust cap is covering vent and in good
condition as this protects the breather hole.
When checking for gas leaks around governor, be
aware that unburned gas may be vented occasionally
to release pressure on diaphragm. This should not be
confused with a gas leak.
3.11 FAULT CHECK LIST
If a flame is not established on any burners (hob or
oven), follow this check list.
1. Check mains gas is ON.
2. Check pressure at test point to ensure gas is flowing to
unit.
3. If pressure does not register then check governor is
fully operational or check for line blockage.
4. If gas is present, check burner injector for blockage.
5. If injector is OK then check FFD is engaging and
passing gas.
6. OVEN ONLY - Check for spark at spark electrode.
7. OVEN ONLY - If there is no spark then check spark
d i m e n s i o n s ( f i g 1 2 ) and HT lead connections.
Also check igniter.
8. OVEN ONLY – Note: Spark may be present but will still
not light burner unless dimensions relative to burner
are as Fig 12.
Note: If after adjusting the electrode to the correct
dimensions (fig 12), a spark is not present, or is
present but will not light burner, check the following:
Check Spark lead and return earth wire connections at
piezo spark igniter body.
Check for clean contact between burner fixing feet and
oven base, using spring washers under screw heads.
9. If flame is still not present, then re-check from start.
If flame is established but not maintained, follow
this check list.
1. Check thermocouple is positioned correctly in burner
flame. (fig 12) Burner ports must be clean.
2. Check thermocouple is not damaged and is secured
to gas valve FFD section to allow FFD to energise.
3. Check FFD is energising and maintaining flame.
4. If, after carrying out the above, burner is still not
maintaining flame then re-check from start.
