PRELIMINARY CHECKS
Preliminary checks for First start-up
Upon completing installation, before contacting the TAC the in-
staller must check:
▶
water-heating, electrical and gas systems suitable for the re-
quired 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 (methane
or LPG);
▶
supply gas pressure complying with the values of Table
3.3
p. 22, with max tolerance ±15%;
▶
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.
Abnormal or hazardous installation situations
Should any abnormal or hazardous installation situations be
found, the TAC 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 mate-
rials;
▶
conditions that do not warrant access and maintenance in
safety;
appliance switched on/off with the main switch, in-
stead of the control device provided (DDC, CCP/CCI
or external request);
▶
appliance defects or faults caused during transport or instal-
lation;
▶
gas smell;
▶
non-compliant mains gas pressure;
▶
non-compliant flue gas exhaust;
▶
all situations that may involve operation abnormalities or are
potentially hazardous.
Non-compliant system and corrective actions
Should the TAC find any non conformities, the user/installer is
bound to perform any corrective procedures required by the
TAC.
After performing the remedial actions (the installer's responsi-
bility), if the TAC deems that safety and conformity conditions
are in place, "First start-up" may be effected.

WARNINGS
General warnings
Prior to using the appliance carefully read the warnings
in Chapter III.1
p. 4, providing important information
on regulations and on safety.
First start-up by TAC
First start-up may exclusively be carried out by a Robur
TAC (Chapter 5
p. 29).
Never power the appliance off while it is running
NEVER power the appliance off while it is running (ex-
cept in the event of danger, Chapter III.1
the appliance or system might be damaged.
6.2
SWITCH ON AND OFF
Routine switching on/off
The appliance may exclusively be switched on/off by
means of the suitably provided control device (DDC,
CCP/CCI or external requests).
Do not Switch On/Off with the power supply switch
Do not switch the appliance on/off with the power sup-
ply switch. This may be harmful and dangerous for the
appliance and for the system.
Inspections before switching on
Before switching on the appliance, ensue that:
gas cock open;
appliance electrical power supply (main switch (GS)
ON);
DDC or CCP/CCI power supply (if present);
water circuit ready.
How to switch on/off
▶
If the appliance is controlled by a DDC or by a CCP/CCI (sys-
tems (1) and (2) see Paragraph 1.7
p. 16), refer to the re-
spective manuals.
▶
If the appliance is controlled by external request (e.g. ther-
mostat, clock, button, ... with voltage-free NO contact), (sys-
tem (3) see Paragraph 1.7
p. 16), the appliance is switched
on/off by the ON/OFF positions of the external control de-
vice.
After switching on with the control, in normal operating condi-
tions, the appliance starts/stops automatically according to the
user's thermal needs, supplying hot water at the programmed
temperature.
Although the external request is in the "ON" position, this
does not mean the appliance will start immediately, but
it will only start when there are actual service demands.
