steam-boX. installation, use and maintenance manual
1. Installation
1.7. Gas connection
(only for gas ovens)
Nota bene
the oven is originally calibrated for functioning with
the gas type specified during ordering.
the type of gas for which the oven is adjusted
is reported on the technical plate found on the
appliance (
fig. 10
,
ref. A
).
During testing, ascertain the factory
calibrations carried out on the burners are
appropriate for the specific installation type,
by means of analysis of the gases produced
by combustion (CO
2
and CO) and check of the
thermal capacity.
specifically, with oven functioning at full capacity,
the values of the undiluted Co present during
draining, must be within 1000 ppm. if the presence
of undiluted Co over such limit is detected, the
adjustment of the burners must be checked by a
technician authorised by the manufacturer, who
will make all due amendments to the devices
governing combustion and to the relative parameters.
the detected data must be recorded and become
integrating part of the technical documentation of
that appliance.

Installation prescriptions
the oven installation and commissioning operations must be carried out only by qualified staff according to
regulations and standards in force.
the gas systems, the electric connections and the installation premises of the appliances must be compliant
with regulations and standards in force.
bear in mind that the air necessary for combustion of the burners is of 2 m
3
/h per kW of installed power.
in activities open to the public, the standards for the safety prevention of accidents and fire and panic must
be complied with.
the connection to the gas supply fitting can be carried out using flexible metal piping, interposing an approved
shut-off cock in an easily accessible point.
ensure that the flexible metal connection tube to the gas inlet fitting does not touch overheated parts of the
oven and that it is not submitted to torsion or extension stresses.
Use securing clips compliant with installation standards.
Checks to be carried out before installation
on the technical plate located on the left side of the oven (
fig. 10
,
ref. A
) check that the appliance has been
tested for the type of gas available with the user.
Check the data on the technical plate (
fig. 10
) that the pressure reducer capacity is sufficient for powering
the equipment.
avoid interposing section reductions between the reducer and the appliance.
We recommend mounting a gas filter upstream of the pressure regulator to guarantee optimal oven functioning.
