FIRST START-UP
First start-up entails checking/setting up the combus-
tion parameters and may exclusively be carried out by
a Robur AT. NEITHER the user NOR the installation tech-
nician is authorised to perform such operations, under
penalty of voiding the warranty.

PRELIMINARY CHECKS
Preliminary checks for first start-up
Upon completing installation, before contacting the AT the in-
staller must check:
▶
Water, electrical and gas systems suitable for the required
capacities and equipped with all safety and control devices
required by the regulations in force.
▶
Absence of leaks in the water and gas systems.
▶
Type of gas for which the appliance is designed (natural gas
or LPG).
▶
Supply gas pressure complying with the values of Table
5.1
p. 31, with max tolerance ±15%.
▶
Correct operation of the flue exhaust duct.
▶
Power supply mains complying with the appliance's rating
plate data.
▶
Appliance correctly installed, according to the manufactur-
er's instructions.
▶
System installed in a workmanlike manner, according to na-
tional and local regulations.
Before performing the first start-up, the AT is required to:
▶
Check that the whole system has been set up in accordance
with its design, following the instructions supplied by the
manufacturer and respecting current regulation. The project
must have been carried out by a skilled professional.
▶
Check personally that all of the connections (hydraulic, gas
and electrical) of the appliance (and of the DDC, if any) have
been made correctly.
▶
Check that the necessary conditions for system compliance
effectively exist (as per the declaration consigned to the user
by the qualified firm that has carried out the installation of
the appliance).
▶
Check that the water pressure and flow in the hydraulic cir-
cuit and the static supply network pressure are correct, as
indicated by the manufacturer.
The declaration of compliance certifies that the system
conforms to current regulations. This declaration is a
compulsory document, and as such must be issued by
law to the owner by the qualified firm that has carried
out the installation of the appliance.
Abnormal or hazardous installation situations
Should any hazardous installation situations be found, the AT
shall not perform first start-up and the appliance shall not be
commissioned.
These situations may be:
▶
Appliance installed inside a room.
▶
Failed compliance with minimum clearances.
▶
Insufficient distance from combustible or flammable materi-
als.
▶
Conditions that do not warrant access and maintenance in
safety.
▶
Appliance switched on/off with the main switch, instead of
the control device provided (DDC, or external request).
▶
Appliance defects or faults caused during transport or
