During gas connection and re-connection, a sealing material
that is either
• PTFE tape approved to BS EN 751-3;
• Or jointing compound suitable for Natural Gas complying
to BS 6956-5 or BS EN 751-1
should be used between connection surfaces.
• Only a suitably qualified and Gas Safe Registered Engineer may convert the appliance to a different

• When using Butane gas a supply pressure of 28 -30 mbar is required.
• When using Propane gas a supply pressure of 37 mbar is required.
• Flexible hoses must be manufactured in accordance with BS669 part 1 and be of the correct
construction for the type of gas being used.
• Gas hoses designed for natural gas MUST NOT be used for supplying LPG gas (LPG gas hoses can be
identified by a either a red band or stripe on the rubber outer coating of the hose).
• The hose should not be crushed or trapped or be in contact with sharp or abrasive edges. It should
also not be subjected to corrosion by acidic cleansing agents.
To Connect the Gas Supply
1.
Connect the gas supply to the gas inlet at the rear of the cooker. The gas hose must hang in a "U" shape
behind the cooker.
2.
Undertake a full gas tightness test.
3.
To avoid damage to the appliance gas rail inlet pipe tighten the fittings using two suitable spanners.
4.
Using a suitable leak detection fluid solution check each gas connection one at a time by brushing the
solution over the connection. The presence of bubbles will indicate a leak. If there is a leak, tighten the
fitting and then recheck for leaks.
Do not use a naked flame to test for leaks.
