NOTE: Gas regulator supplied is
convertible between Natural Gas
and LP Gas, but it’s outlet
pressure is fixed ex-factory and
is NOT to be adjusted.
- Town Gas Only.
1. Remove slotted cap from regulator.
2. Turn ‘On’ gas supply and appliance.
3. Adjust pressure adjusting screw to achieve correct burner
operating pressure.
NOTE: Measure burner operating pressure at gas valve outlet
test point with burner operating at 'High Flame'
setting.
4. Verify operating pressure remains correct (Re-adjust
regulator if required).
5. Screw cap nut back onto regulator.
On completion of gas conversion, replace gas type labels located at:-
- Rear of unit, above gas connection.
- Beside rating plate.
Before leaving installation;
1. Check all gas connections for leakage using soapy water or other gas detecting equipment.
2. Carry out a ‘Commissioning’ check of appliance as shown in Installation Section of this manual.
3. Ensure any adjustments done to components that have adjustments / settings paint sealed are to be
