1.3 Connection to gas supply (for gas ovens only)

N.B.

The oven is factory set for the type of gas spe-

cied in the order.

The label attached to the appliance indicates
which type of gas the oven has been set for.

During testing, the gas produced throu­gh combustion (CO2 and CO) should be
analysed and the nominal heat rating
should be measured to ensure that the
burners have been correctly calibrated
for the type of installation required.

Data collected should be written down and in­cluded in the technical documentation of the
appliance.

Installation instructions

The oven should be installed and commissioned by qualied technicians in compliance

with current regulations and legislation.
Gas appliances, electrical connections and rooms where the appliance is to be sited
must comply with current regulations and legislation.
The air requirement of the burners is 2 m3/h per kW of power installed.

Premises open to the public must comply with accident prevention laws and re safety
regulations. A exible metal hose can be used to connect the appliance to the gas sup­ply; make sure you t an approved tap in a point that is easy to reach.
Make sure that the exible hose is not twisted or over-stretched or in contact with parts

of the oven subject to overheating.
Use locking clamps complying with installation regulations.

Checks to be carried out prior to installation.

Check the label on the left-hand panel of the oven to make sure that the appliance has
been set for the type of gas on your premises.
Check the label to make sure that the capacity of the gas pressure reducer is adequate
for the supply of the appliance.
Do not insert section reducers between the reducer and the appliance.

We recommend tting a gas lter between the tap and pressure regulator to ensure

perfect performance.

1. Installation

Connect the oven to the gas supply using a special R 1/2”

hose with an internal section of at least 16 mm.

Connection to gas supply must be carried out using rigid or

exible metal pipes. Use taps or gates with an internal diame-

ter that is greater than that of the hose.

After connecting the appliance to the gas supply make sure

that there are no leaks from joints or connections. You can

test for leaks by using soapy water or foaming agent for leak

detection.

Gas ovens should be inspected in compliance with spe-

cic regulations once a year by an authorised techni-

cian who will analyse combusted gases and check no-

minal heat rating.

The appliance can work correctly only when gas pres-

sure keeps within specic values for each gas type (see

table).

If the pressure falls outside these values, it will not be possible

to achieve optimum functioning of the appliance and for it to

be installed permanently. Should this happen, call a technician

to check your gas mains (ducts, gates and eventually pressure

reducers) then, if necessary, contact your gas provider.
