REASSEMBLE IN REVERSE ORDER.
Adjustments
Pilot
1.
Remove front panel as described under GAINING ACCESS TO GAS CONTROL.
2.
To increase gas pressure to pilot, turn adjustment screw located at the top right hand side of the flame failure
devise anti-clockwise.
3.
To decrease gas pressure to pilot, turn adjustment screw located at the top right hand side of the flame failure
devise clockwise.
4.
REASSEMBLE IN REVERSE ORDER ENSURING POSITION OF PILOT IS AS FOLLOWS;
Ensure pilot light head is light head is located no further than 45mm from the injector located opposite the
burner inlet.
Servicing Knee Valve
– Where Fitted
The knee valve incorporates a cartridge design for ease of service.
1.
Follow procedure described under GAINING ACCESS TO GAS AND/OR WATER SYSTEM
2.
To gain access to knee valve cartridge undo knee valve where the deflector meets the cartridge area.
3.
REASSAMBLE IN REVERSE ORDER
Gas Type Conversion
The following parts componentry require changing the appliance from NG to LPG (vice-versa);
1.
Regulator.
2.
Burner.
3.
Pilot.
In case of any failure in the functioning of the knee valve, unscrew the head assembly and clean the
mechanism under running water. Only use liquid cleaning products. All cleaning products containing dry
powder or powder in suspension are not to be used!
A specific devise is integrated in the cartridge unit to adjust the flow rate. To adjust the flow rate;
1.
Undo head assembly
2.
Pull off flow adjustor
3.
On the exposed end of the housing there are 4 cut-outs for alternative flow rates.
4.
Select one for increased/reduced flow.
5.
Replace flow adjustor with window over selected cut-out.
6.
Screw head assembly into the tap body and tighten fully.
