Important
On completion of the operation, replace the old rating
sticker with one indicating the new type of gas used.
This sticker is available from our Service Centres.
Note
Should the pressure of the gas used be different (or
vary) from the recommended pressure, it is necessary
to fit a suitable pressure regulator onto the inlet pipe in
compliance with current National Regulations relative
to “regulators for channelled gas”.
