When connecting the appliance to the gas supply with rigid pipes or a flexible hose,
make sure that
•
you use rigid pipes or a flexible hose complying with applicable local regulations. The
flexible hose shall be of the correct construction for the type of gas being used and of
the correct size to maintain the heat output of the appliance.
•
the connection with rigid metal pipes does not cause stress or pressure to the gas
piping.
•
the flexible hose is not under tension, twisted, kinked or too tightly bent, neither while
the appliance is in use nor while it is being connected or disconnected.
•
the flexible hose does not exceed 2000 mm in length (or refer to applicable local
regulations) and does not come into contact with sharp edges, corners or moving
parts, as these may cause abrasion. Use a single flexible hose only; never connect the
appliance with more than one flexible hose.
•
the flexible hose can easily be inspected along its entire length to check its condition;
if it has an expiry date, it should be replaced before that date.
•
if using a flexible hose which is not entirely made of metal, make sure that it does not
come into contact with any part of the cooktop with a surface temperature of 70°C or
above (or refer to applicable local regulations).
•
the flexible hose is not subject to excessive heat by direct exposure to flue products or
by contact with hot surfaces.
•
the rigid pipe or flexible hose is replaced if it shows signs of wear or damage.
•
a gas pressure regulator, in compliance with the applicable local regulations, is
installed when connecting to an LPG cylinder.
•
the socket into which the plug of the flexible hose fit is permanently attached to a firmly
fixed gas installation pipe and is positioned so that the hose hangs freely downwards.
•
the plug of the flexible hose is accessible after installation, so that it can be disconnected
for service or removal.
•
you inform the customer that the cylinder valve or the supply valve immediately by the
appliance should be closed when the cooktop is not in use.
•
you inform the customer that the rigid pipe or flexible hose should not be subjected to
corrosion by acidic cleaning agents.
After connecting the appliance to the gas supply, make sure that you
•
check that the connections are correctly sealed using a soapy solution, but never a
naked flame.
•
check whether the injectors are correct for the type of gas being used. If not, follow the
instructions under "GAS MAINTENANCE".
•
replace the sealing washer/s on the slightest sign of deformation or imperfection. The
sealing washer/s is/are the part/s which guarantee/s a good seal in the gas connection.
GAS CONNECTION FOR TOWN GAS ONLY
The gas connection is made up of (Fig. 2.3):
•
the appliance inlet pipe;
•
the foating nut;
•
the brass elbow;
•
the brass conical connector [1/2" BSP taper (conical), BS EN 10226-1, male thread];
•
