BORETTI CFBG902AN Instruction On Mounting And Use Manual page 225

IMPORTANT:
• Note: In France, use a tube bearing
the mark NF GAZ.
• 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.
• After connecting to the mains, check
that the couplings are correctly
sealed, using soapy solution, but
never a naked flame.
To fix the parts it is necessary to
•
operate with 2 spanners (fig. 9.9).
• The connection with rigid metal pipes
must not cause stress or pressure to
the gas piping.
The rigid or flexible pipes must conform
•
with applicable local regulations. The
flexible pipe shall be of the correct
construction for the type of gas being
used.
Make sure the flexible pipe can easily
•
be inspected along its entire length to
check its condition; it must be replaced
before the expiry date (marked on the
pipe) or if it shows signs of wear or
damage. Make sure the flexible pipe
does not come into contact with sharp
edges, corners or moving parts.
Use a single flexible pipe only; never
•
connect the appliance with more than
one flexible pipe.
Make sure the flexible pipe 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.
Make sure the flexible pipe does not
•
exceed 2000 mm in length or 750 mm
for a rubber hose (or refer to applicable
local regulations).
If using a flexible pipe which is not
•
entirely made of metal, make sure that
it does not come into contact with any
part of the appliance with a surface
temperature of 70°C or above (or refer
to applicable local regulations).
• When using a rubber hose for the gas
connection, make sure it is as short
as possible, without twists or kinks.
To avoid any possible abrasion, make
sure the hose does not come into
contact with sharp edges, corners or
moving parts.
• Make sure the hose is not subject to
excessive heat by direct exposure to
flue products or by contact with hot
surfaces.
The rigid or flexible pipe must be
•
replaced if it shows signs of wear or
damage.
The rigid or flexible pipe must not be
•
exposed to cleaning products (to avoid
any possible corrosion).
• The customer must be informed that
the gas shutoff valve ahead of the
appliance should be closed when the
product is not in use.
