Gas Fired Steam Tilting Kettles
Converting Between Natural and Propane Gas
To convert the kettle from natural gas to LP or LP to natural gas use OEM Conversion Kits. Contact manufacturer or your
authorised service company for the kits part numbers.
To convert gas combination control from one gas to another:
1. Turn off main gas supply to the appliance.
2. Remove the regulator cap screw and pressure
regulator adjusting screw. See Figure 3.
3. Remove the existing spring.
4. Insert the replacement spring with tapered end down.
See Figure 4.
5. Install the new plastic pressure regulator
adjustment screw so that the top of the screw is
flush (level) with the top of the regulator. Turn the
pressure regulator adjustment screw clockwise
six complete turns. This provides a preliminary
pressure setting of about 10 inch (254 mm) W.C.
for LP regulator and 4 inch (102 mm) W.C. for
natural gas regulator.
6. Check the regulator setting either with a manometer or
by clocking the gas meter.
7. Install the new cap screw.
8. Mount conversion label on control.
9. Install control and appliance according to appliance
manufacturer's instructions.
