1.18 FLUES, CHIMNEYS, CHIMNEY POTS
AND TERMINALS.
The flues, chimneys and chimney caps for
the evacuation of combustion products must
be in compliance with applicable standards.
Chimneys and roof-installed exhaust terminals
must comply with the outlet height and with the
distance from technical volumes set forth by the
technical standards in force.
Positioning the wall exhaust terminals.
The
exhaust terminals must:
- be installed on external perimeter walls of the
building;
- be positioned according to the minimum
distances specified in current technical
standards.
Combustion products exhaust of natural or
fan assisted appliances in open-top closed
environments.
In spaces closed on all sides
with open tops (ventilation pits, courtyards
etc.), direct combustion product exhaust is
allowed for natural draught or fan assisted gas
appliances with a heat input range from 4 to 35
kW, provided the conditions as per the current
technical standards are respected.
1.19 SYSTEM FILLING.
Once the boiler and the heat pump have been
connected, fill the system via the filling valve (Fig.
1-28 and 2-6). Filling is performed at low speed
to ensure release of air bubbles in the water via
the boiler, heat pump and heating system vents.
The boiler incorporates an automatic vent valve
fitted on the circulator pump and one on the system
vent tank.
Check if the cap is loose.
Open the radiator
vent valves.
Close radiator vent valves when only water
escapes from them.
Close the filling valve when the boiler manometer
indicates approx. 1.2 bar.
N.B.:
during these operations activate the
automatic vent functions featured on the boiler
(active upon initial ignition) and on the heat
pump (see relative instructions booklet).
Vent
the boiler circulation pump by loosening the front
cap and keeping the motor running.
Tighten the
cap after the operation.
1.20 CONDENSATE TRAP FILLING.
On first lighting of the boiler combustion
products may come out the condensate drain;
after a few minutes’ operation check that this no
longer occurs. This means that the trap is filled
with condensate to the correct level preventing
the passage of combustion products.
1.21 GAS SYSTEM START-UP.
To start up the system, make reference to the
Standard: This divides the systems and therefore
the start-up operations into three categories: new
systems, modified systems, re-activated systems.
In particular, for new gas systems:
- open windows and doors;
- avoid presence of sparks or open flames;
- bleed all air from the pipelines;
- check that the internal system is properly sealed
according to specifications.
1.22 BOILER START UP (IGNITION).
In order to issue the Declaration of Conformity
required by law, one must comply with the
following requirements to commission the
boiler (the operations listed below must only
be performed by qualified personnel and in the
presence of staff only):
- check that the internal system is properly sealed
according to specifications;
- make sure that the type of gas used corresponds
to boiler settings;
- check that there are external factors that may
cause the formation of fuel pockets;
- switch the boiler on and check correct ignition;
- make sure that the gas flow rate and relevant
pressure values comply with those given in the
manual (Par. 3.20);
- ensure that the safety device intervenes in the
event of gas supply failure and check the relative
intervention time;
- check the intervention of the main switch
located upstream from the boiler and in the
boiler;
- check that the intake/exhaust concentric
terminal (if fitted) is not blocked.
The boiler must not be started up even if only
one of the checks should be negative.
N.B.:
the preliminary boiler check must be
carried out by an authorised company. The boiler
warranty is valid as of the date of testing.
The test certificate and warranty is issued to the
user.
