BORETTI CFBG902AN2 Instruction On Mounting And Use Manual page 64

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.
