GAS CONNECTION
Before connecting the appliance check that the
data on the rating plate affixed to the cooker,
correspond to those of the gas mains.
A label on the back of this handbook and at
the back of the cooker gives the appliance
adjustment conditions, that is, the type of gas
and operating pressure.
Once the cooker is installed, check there are no
leaks using a soapy solution (never a flame).
The appliance’s gas inlet fitting is a threaded 1/2”
male cylindrical type, in compliance with the ISO
228-1 standards. If gas is distributed through ducts
the appliance must be connected to the gas mains with:
•
a rigid steel pipe, in accordance with standards,
whose joints must be made using threaded fittings
in accordance with the UNI-ISO 7/1 standard. The
use of hemp with suitable adhesives or Teflon tape
as a sealant is allowed.
•
copper pipe, in accordance with the standard,
whose joints must be made using sealed fittings in
accordance with the standard.
•
a flexible stainless steel, seamless pipe in
accordance with the standard, with a maximum
2 metre extension and seals in accordance with
the standard.
•
a flexible rubber hose in accordance with the
standard, with an 8 mm diameter for LPG and
13 mm for natural gas or town gas, maximum
1500 mm in length, firmly secured to the hose
fitting with a safety clamp as per the standard.
If the gas is supplied directly from a gas cylinder,
the appliance, fed by a pressure regulator in
accordance with the standard, must be connected:
•
with a copper pipe in accordance with the standard,
INSTRUCTIONS FOR THE INSTALLER
whose joints must be made using sealed fittings in
accordance with the standard.
•
with a flexible stainless steel, seamless pipe in
accordance with the standard, with a maximum
2 metre extension and seals in accordance with
the standard. We recommend applying the special
adapter to the flexible pipe, easily found on the
market, to facilitate connection to the pressure
regulator’s hose fitting on the cylinder.
•
with a flexible rubber hose in accordance with
the standard, with an 8 mm diameter, minimum
400 mm in length, maximum 1500 mm in length,
firmly secured to the hose fitting with a safety
clamp as per the standard.
ATTENTION:
• If the appliance is going to be recessed (class 2
subclass 1), connect it to the gas supply source
using only flexible stainless steel, seamless
pipes in accordance with the standard.
• If the appliance is going to be installed free-
standing (class 1) and if you use the flexible
rubber hose, it is necessary to follow the
instructions and figure 17 given below:
• On its route, the hose must not touch any parts
where the temperature is more than 95°C.
• The hose must not be subject to any kind of
torsional stress or tractive force, there must be
no pinched parts or really sharp bends.
• It must not touch anything that can cut, that has
sharp corners, etc.
