sheet of insulating material (cork, polystyrene or other
similar) between the control system and the wall.
By following the above guidelines, unwanted
starting and stopping of the system can be avoided
and optimal comfort in the heated space can be
guaranteed.
5 FIRST STARTUP
First start-up entails checking/setting up the com-
bustion parameters and may exclusively be carried
out by a Robur TAC. NEITHER the user NOR the in-
stallation technician is authorised to perform such
operations, under penalty of voiding the warranty.
The installer is obliged to carry out preliminary
checks described in Paragraph 5.1 p.42 .
5.1 PRELIMINARY CHECKS
Paragraph dedicated to the installer.
5.1.1 Preliminary checks for rst start-up
Upon completing installation, before contacting the TAC
the installer must check:
▶ Electrical and gas systems suitable for the required ca-
pacities and equipped with all safety and control de-
vices required by the regulations in force.
▶ Absence of leaks in the gas system.
▶ Type of gas for which the appliance is designed (natu-
ral gas, LPG or other gas).
▶ Supply gas pressure complying with the values of
Table 3.1 p.29 , with max tolerance ±15%.
▶ Correct operation of the ue exhaust duct.
▶ Combustion air feed and ue gas exhaust correctly
carried out according to the regulations in force.
▶ Power supply mains complying with the appliance's
rating plate data.
▶ Appliance correctly installed, according to the manu-
facturer's instructions.
▶ System installed in a workmanlike manner, according
to national and local regulations.
5.1.2 Abnormal or hazardous installation
situations
Should any abnormal or hazardous installation situations
be found, the TAC shall not perform rst start-up and the
appliance shall not be commissioned.
These situations may be:
▶ Failed compliance with minimum clearances.
▶ Insucient distance from combustible materials.
▶ Conditions that do not warrant access and mainte-
nance in safety.
▶ Appliance switched on/o with the main switch, in-
stead of the provided control device.
▶ Appliance defects or faults caused during transport or
installation.
▶ Gas smell.
▶ Non-compliant mains gas pressure.
▶ Non-compliant ue gas exhaust.
▶ All situations that may involve operation abnormali-
ties or are potentially hazardous.
5.1.3 Non-compliant system and corrective
actions
Should the TAC nd any non conformities, the user/install-
er is bound to perform any corrective procedures required
by the TAC.
After performing the remedial actions (the installer's re-
sponsibility), if the TAC deems that safety and conformity
conditions are in place, rst start-up may be eected.
5.2 COMBUSTION PARAMETERS CHECK
Paragraph reserved exclusively to TACs.
The gas unit heater is supplied with the gas valve
already calibrated with respect to the fuel indi-
cated on the sticker next to the gas connection.
Therefore, during the commissioning, only the CO
2
value must be checked and, only if the check is not
successful, or after a gas changeover, the complete
check procedure must be carried out.
The CO
2
value should be checked with the thermo-
formed door closed, while the gas valve should be
adjusted with the thermoformed door open.
If a dierential pressure gauge is used, it is neces-
sary to connect the pressure intake A of the gas
valve to the + (positive) port of the pressure gauge.
5.2.1 R15/R20/R30/R40/R50
The simple check of CO
2
values corresponds to
steps 8 to 13 of the procedure below, after turning
on the unit. If the check is not successful, the com-
plete procedure must be carried out.
Figure 5.1 p.43
1. If the appliance is running, switch it o with the appli-
cable control system.
2. Open the thermoformed door.
3. Remove the cap over the oset adjustment screw (C)
of the gas valve.
