1.10 FLUE EXHAUST TO FLUE/CHIMNEY.
Flue gas exhaust does not necessarily have to be
connected to a branched type traditional ue.
e ue exhaust can be connected to a special
LAS type multiple ue. Multiple and combined
ues must be specially designed according to
the calculation method and requirements of the
standards, by professionally qualied technical
sta. Chimney or ue sections for connection
of the exhaust pipe must comply with requisites
of technical standards in force.
1.11 DUCTING OF EXISTING FLUES.
With a specic “ducting system” it is possible
to reuse existing ues, chimneys and techni-
cal openings to discharge the boiler ue gases.
Ducting requires the use of ducts declared to be
suitable for the purpose by the manufacturer.
Follow the installation and user instructions
provided by the manufacturer and the require-
ments of standards.
1.12 FLUES, CHIMNEYS AND CHIMNEY
CAPS.
e ues, chimneys and chimney caps for the
evacuation of combustion products must be in
compliance with applicable standards.
Positioning the draught terminals. e draught
terminals must:
- be installed on external perimeter walls of the
building;
- be positioned according to the minimum dis-
tances specied in current technical standards.
Combustion products exhaust of fan assisted
appliances in open-top closed environments.
In spaces closed on all sides with open tops
(ventilation pits, courtyards etc.), direct ue gas
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.
1.13 SYSTEM FILLING.
Once the boiler is connected, proceed with sys-
tem lling via the lling valve (Fig. 2-2).
Filling is performed at low speed to ensure release
of air bubbles in the water via the boiler and
heating system vents.
e boiler has a built-in automatic venting valve
on the pump. Check if the cap is loose.
Open the radiator air vent valves. Close radiator
vent valves only when water escapes from them.
Close the lling valve when the boiler manometer
indicates approx. 1.2 bar.
N.B.: during these operations turn on the circula-
tion pump at intervals, by means of the stand-by/
summer winter switch positioned on the control
panel. Vent the circulation pump by loosening the
front cap and keeping the motor running.
Tighten the cap aer the operation.
1.14 GAS SYSTEM STARTUP.
To start up the system proceed as follows:
- open windows and doors;
- avoid presence of sparks or naked ames;
- bleed all air from pipelines;
- check that the internal system is properly sealed
according to specications.
1.15 BOILER STARTUP IGNITION.
For issue of the envisioned Declaration of Con-
formity, the following must be performed for
boiler start-up:
- check that the internal system is properly sealed
according to specications;
- make sure that the type of gas used corresponds
to boiler settings;
- switch the boiler on and check correct ignition;
- make sure that the gas ow rate and relevant
pressure values comply with those given in the
manual (par. 3.18);
- ensure that the safety device is engaged in the
event of gas supply failure and check activation
time;
- check activation of the main switch located
upstream from the boiler;
- check that the intake/exhaust concentric ter-
minal (if tted) is not blocked.
e boiler must not be started up even if only
one of the checks should be negative.
N.B.: the boiler preliminary check must be carried
out by a qualied technician. e conventional
boiler warranty is valid as of the date of testing.
e test certicate and warranty is issued to the
user.
