1.17 FLUES, CHIMNEYS, CHIMNEY CAPS
AND TERMINALS.
e ues, chimneys and chimney caps for the
evacuation of combustion products must be in
compliance with standards in force. e chimney
caps and the roof exhaust terminals must respect
the outlet quotas and the distance of the foreseen
technical volumes from the current technical
regulations.
Positioning the wall exhaust terminals. e
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, air shafts,
courtyards etc.), direct ue exhaust is allowed
for conventional or fan assisted draught gas
appliances with a heating power range from 4 to
35 kW, provided the conditions as per the current
technical standards are respected.
1.18 SYSTEM FILLING.
Once the boiler is connected, proceed with
system lling via the lling valve (Fig. 1-29 and
2-8). 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 circulator. Check if the cap is loose. Open the
radiator air vent valves.
Close radiator vent valves when only water
escapes from them.
Close the lling valve when the boiler manometer
indicates approx. 1.2 bar.
N.B.: during these operations start/up the
circulation pump at intervals, acting on the main
switch positioned on the control panel. Vent the
circulation pump by loosening the front cap and
keeping the motor running. Re-tighten the cap
aer the operation.
1.19 FILLING THE CONDENSATE TRAP.
On first lighting of the boiler combustion
products may come out the condensate drain;
aer a few minutes’ operation check that this no
longer occurs. is means that the trap is lled
with condensate to the correct level preventing
the passage of combustion products.
1.20 GAS SYSTEM STARTUP.
To start up the system, refer to the current
regulations. This divides the systems and
therefore the start-up operations into three
categories: new systems, modied systems, re-
activated systems.
In particular, for new gas systems:
- 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.
1.21 BOILER START UP IGNITION.
For issue of the Declaration of Conformity
provided for by Italian Law, the following must
be performed for boiler start-up:
- check that the internal system is properly sealed
according to specications;
- ensure that the type of gas used corresponds to
boiler settings;
- switch the boiler on and ensure 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 and in the boiler;
- check that the concentric intake-exhaust
terminal (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 boiler warranty
is valid as of the date of testing.
e test certicate and warranty is issued to the
user.
