3.3 CLEANING
3.3.1 Burners
Burners should be cleaned periodically to maintain
maximum performance as detailed in User
Instructions. Burners are best cleaned with a wire brush;
port blockage should be freed using a metal broach, any
loose material being shaken out via burner shank.
Ensure burners are dry and free from any cleaning
material before replacing.
Check adjustment as detailed in Section 1.
3.3.2 Injectors
Injectors are best cleaned with a wooden splinter or soft
fuse wire. Metal reamers may distort or increase orifice
size and their use should be avoided.
3.4 THERMOCOUPLES and
FLAME FAILURE DEVICE (FFD)
3.4.1 Flame Failure Device Magnet Unit
To remove and replace FFD magnet unit, the following
procedures must be followed.
Remove hob components as detailed in Section 3.2.2.
Undo FFD thermocouple at rear of tap, undo FFD
section at tap rear and withdraw.
Replace in reverse order.
3.4.2 Thermocouple
Follow section 3.1.1 to instruction e)
Remove nut securing thermocouple to burner support
bracket. Pull thermocouple through bracket from
underside.
Undo thermocouple connection at FFD section of gas tap
and carefully remove thermocouple.
Replace in reverse order.
Ensure thermocouple does not touch any part of burner
when fully re-assembled.
3.5 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.
3.6 GAS TAPS
Note
Plugs and bodies are machined in pairs and are
therefore not interchangeable. Always clean one tap at
a time.
3.6.1 Service
Remove control knobs and facia 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.
3.7 FAULT CHECK LIST
If a flame is not established on the burners 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. 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. 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.
