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 compli-
ance with current National Regulations relative to “regu-
lators for channelled gas”.
