The group of attachments (fig. 10.3) is
made up of:
• 1 nut “ A ” ( external cylindrical thread
ISO 228-1)
• 1 sealing washer “ D ”
• 1 conical connection “ B ” (internal
cylindrical thread ISO 228-1, external
conical thread ISO 7-1)
• 1 Butane/Propane Gas connector “ C ”.
Exception for single unit cookers that
are not built-in.
• These cookers must be connected by
a flexible elastomer hose with a built–in
undetachable mechanical nozzle. Only use
those hoses that are authorised with the
label “AGB/BGV”.
• Two types of flexible elastomer hoses: until
April 2005, there were 2 types of flexible
elastomer hoses on the market:
- the old assymetrical model, including an
end with a fixed nozzle at the side of the
cooker, and a nozzle with a loose nut
and a built-in flat sealed joint at the side
of the inside fitting (stop cock) .
- the new symmetrical model, including a
nozzle with a loose nut at both sides,
with a built-in flat sealed joint. This
symmetrical model is the only one that
will be available after the time limit.
When installing a new cooker, or replacing
an existing one, the symmetrical model must
always be used.
Assembly
The gas inlet on the old cookers is equipped
with a conical thread ISO 7-1 – and the hose
is assembled as follows:
1. apply a sealing product to the thread on
the appliance: a strip of teflon or sealing
paste for threads (colmat) plus some
acrylic wool;
2. tighten up the linking component (the
cylindrical inside thread ISO 7-1 to the
cylindrical ouside thread ISO 228-1) with
the two keys on the cooker;
3. check that the sealed joint is firmly
inserted inside the moveable connection
on the elastomer hose (new model);
4. tighten up by hand the elastomer hose on
both sides;
5. tighten up with a spanner;
6. open the stop cock and check that there
are no leaks (soap bubbles) by smearing
on a frothing product ).
Cookers must be connected using R
HT
materials downstream from the AGB/
BGV certificated gas stop-cock, except for
single unit cookers that are not built-in.
As a general rule, cookers are connected
downstream from the gas stop-cock, by:
• copper pipes having an appropriate wall
thickness, or;
• steel pipes, or;
• flexible R
HT
metal pipes with AGB
certification, fitted in such a way that
they will not be crushed or pulled
during use. Their bending radius must
not be less than that specified by the
manufacturer.
