Positioning the draft terminals. Draft terminals must:
- be installed on external perimeter walls of the building;
- be positioned according to the minimum distances specified in current
technical standards.
Fume exhaust of forced draught appliances in closed open-top envi-
ronments. In spaces closed on all sides with open tops (ventilation pits,
courtyards etc.), direct fume exhaust is allowed for natural or forced draught
gas appliances with a heating power range from 4 to 35 kW, provided the
conditions as per the current technical standards are respected.
1.10 System filling.
Once the boiler is connected, proceed with system filling via the filling valve
(see figure pages 193 and 196). Filling is performed at low speed to ensure
release of air bubbles in the water via the boiler and heating system vents.
The boiler has a built-in automatic venting valve on the circulator. Check
if the cap is loose. Open the radiator air vent valves.
Close vent valves only when water is delivered.
Close the filling valve when the boiler pressure gauge indicates approx.
1.2 bar.
N.B.: During these operations, turn on the circulating pump at intervals
by means of the main selector on the control panel. Vent the circulating
pump by loosening the front cap and keeping the motor running. Retighten
the cap afterwards.
1.11 Filling condensate collection trap.
On first lighting of the boiler fumes may come out the condensate drain;
after a few minutes' operation check that fumes no longer come out. This
means that the trap is filled with condensate to the correct level preventing
the passage of fumes.
1.12 Gas system start-up.
To start up the system proceed as follows:
- open windows and doors;
- avoid presence of sparks or naked flames;
- vent all air from pipelines;
- check that the internal system is properly sealed according to specifica-
tions.
1.13 Boiler start-up (lighting).
For issue of the Declaration of Conformity provided for by Italian Law, the
following must be done for boiler start-up:
- check that the internal system is properly sealed according to specifica-
tions;
- ensure that the type of gas used corresponds to boiler settings;
- switch on the boiler and ensure correct ignition;
- make sure that the gas flowrate and relevant pressure values comply with
those given in the manual (see page 204);
- ensure that the safety device is engaged in the event of gas supply failure
and check activation time;
- check activation of the main circuit-breaker selector upstream of the
boiler and on the unit;
- check that the concentric intake/exhaust terminal (if fitted) is not
blocked.
The boiler must not be started up in the event of failure to comply with
any of the above.
N.B.: The boiler preliminary check must be carried out by a qualified techni-
cian. The boiler guarantee is valid as of the date of testing.
The test certificate and warranty is issued to the user.
