Safety Instructions for the Gas Connection
î
Make sure that the gas type
and pressure of the distribu-
tion network are compatible
with the appliance, as per the
information on the appliance
data plate.
î
The OFFSET (A) setting of the gas valve
is factory-preset and sealed. In some
countries, it is prohibited to change its
setting. Please refer to applicable local
regulations.
î
The CO

, gas fl ow rate, air fl ow rate
and air/gas supply parameters are fac-
tory-preset and may not be modifi ed in
certain countries. Please refer to appli-
cable local regulations.
î
When connecting the gas circuit,
make sure to comply with all appli-
cable local regulations and stand-
ards. The circuit will be equipped
with a meter and a gas pressure
regulator if required.
î
Do not exceed the maximum gas
pressure.
î
The conversion of the appliance
from natural gas to G31 liquefi ed
petroleum gas (propane) or the re-
verse can only be performed by a
qualifi ed professional.
î
Gas conversion shall be per-
formed according to applicable
local regulations. It is prohibited in
some countries. Perform conver-

appliance data plate.
î
Bleed the gas duct and check
thoroughly if all the internal and
external gas pipes and connec-
tions are tight.
î
After gas circuit connection, check
that there is no leak.
î
Use a gas detection device or per-
form a bubble test to check for gas
leaks. Never use an open fl ame, as
it could result in an explosion.
Control the gas pressure and con-
sumption at appliance start up,
and perform the adjustment pro-
cedure provided in this manual.
