3.2 Conversion to Different Gas Type
Note: For the UK/Ireland, the products must not be converted between gases. The gas
taps have been sealed.
Burners can be used with NG or LPG types of gas, provided that the injector orifice appropriate for
the gas delivered are installed. Use a 7mm (
9
/
32
") box spanner to remove the orifice.
To change the injector orifice:-
3.2.1 Turn off the mains supply.
3.2.2 Ensure all gas cocks are turned off.
3.2.3 Remove all burner heads.
3.2.4 Unscrew the injector orifice using a 7mm socket and replace
them with the correct ones. (Size numbers stamped on side or
the top.) e.g:- 70 = 0.70mm
3.2.5 Reset minimum setting (see 3.1).
The label supplied with the orifices can be placed over the existing gas type label to indicate the
change.
Note:Kits of high altitude orifices are available for USA/Canada (these are also suitable for Aus/NZ
900/9002 models). NG Part No. 530463 LP Part No. 530464
These orifices should be used at approximately 6000 feet and above.
3.2.6 To Change the Gas Pressure (4"NG, 11"LP): (USA/Canada Only)
1. Unscrew the cap from the regulator.
2. Check the orientation of the plastic conversion plug, and if necessary, unscrew, turn over and
screw back in (wide section away from cap for LP and against cap for NG - see diagram
below for appropriate orientation).
3. Replace regulator cap.
4. Test gas pressure (test point provision on side of regulator). When converting the regulator for
different settings, the function of the regulator must be checked at a pressure at least 1"WC
(249Pa) above the specified manifold pressure.
