1.9 CONNECTING TO THE GAS MAINS
Connect the oven to connection (A) using metal pipes rigid type, ei-
ther in galvanised steel or copper, situated where they can be seen.
Never use hoses to connect the oven to the gas main.
The appliance must be connected to an on-off mains valve that is
easy to operate.
Use a 3-piece metal joint for connection between the pipe and oven
to facilitate removal.
Guarantee the seal of the joint threads using materials declared, by
their manufacturers, as being specifically suitable also for LPG.
The appliance must be supplied with a suitable type of gas (see the "technical data" table chapter 18).
It is set for use with the type of gas indicated on the "rating" plate.
2.0 CHECKING FOR GAS LEAKS
Once the oven has been installed check there is no gas leaking into the room. This can done by brushing joints
and fittings with soapy water.
Bubbles prove there is a gas leak.
Note: never use bare flames to check for gas leaks.
2.1 TRANSFORMATION FOR DIFFERENT GAS TYPES
The appliances are usually supplied to function with the type of gas of installation KAT I3..., I2..., as stated in
our technical features label.
Exceptionally when the type of gas is not known, the oven will be supply to function in KAT II2..., suitable for a
transformation to a different kind of gas.
IN THIS CASE IF SUCH TRANSFORMATION IS NECESSARY, IT MUST BE DONE ONLY BY QUALIFIED
PERSONNEL, TRAINED BY THE MANUFACTURED WITH THE HELP OF THE TOOLS BELOW DESCRIBED.
The cooking chamber is equipped with a heating system with burner
and pre-mixed gas.
This burner is so called because it mixes air and gas at a ratio of 1:1.
It can burn without producing harmful emissions, even when there
is no more air, usually called secondary air, normally present at the
bottom of the flame.
The system comprises:
1. a gas solenoid valve (A);
2. a Venturi unit for air extraction (B);
3. an electric fan (C);
4. a unit with 2 electrodes (D), one for ignition and the other for
flame control;
5. an electronic control box (E) for burner ignition and flame control;
6. an electronic control box (F) for adjusting the electric fan speed;
7. a "premix" type gas burner, positioned directly on the electric fan.

The appliance has been tested and equipped to operate with the gas shown on the data plate on the right-hand
side of the appliance.
If connections must be made using another type of gas, it will be
necessary to transform using a 3 and 8 mm screwdriver, a frequen-
cy meter, a gas flow gauge and a combustion gas analyzer, strictly
following the following warnings:
2.1A Gas connection pressure control
Connection pressure is measured using a "U"-shaped gauge, on the
pressure input (C) of the gas valve.
Connection pressures are shown in the "Gas connection technical
data" table 1.8
ATTENTION: for the ovens model 207G it's necessary to replace
the fixed air regulator (G) (Fig.2.1A) of the Venturi suction with the
suitable one:
for LPG gas G30= Øi 18
Fig. 2.1B
for natural gas= Øi 22
