1.19 FLUE DUCT SYSTEMS FOR VOIDS AND
CHIMNEYS.
Ducting is an operation through which by the introduction of one
or more relevant pipes, a system is realised for the evacuation of
the combustion products of a gas appliance made up from the
coupling of an existing or new ducting pipe with a chimney, ue or
technical slot (also in new buildings). Flue ducts may be installed
in suitable voids or chimneys provided that the relevant building
regulations permit this. Flue ducting systems must be installed in
strict accordance with the manufacturers instructions.
Immergas ducting system Ø 80 . e “Green Series” 80 Ø exible
ducting system must only be used with Immergas condensing boilers.
In any case, ducting operations must respect the provisions
contained in the standard and in current technical regulations;
in particular, the declaration of conformity must be compiled at
the end of work and on commissioning of the ducted system. e
instructions in the project or technical report must likewise be
followed, in cases provided for by the standard and current tech-
nical regulations. e system or components of the system have
a technical life complying with current standards, provided that:
- it is used in average atmospheric and environmental conditions,
according to current regulations (in particular, by the standards
regarding: absence of combustion products, dusts or gases that
can alter the normal thermophysical or chemical conditions;
existence of temperatures coming within the standard range of
daily variation, etc.).
- Installation and maintenance must be performed according to
the indications supplied by the manufacturer and in compliance
with the provisions in force.
- e max. possible length of the 80 Ø exible ducting vertical
section is equal to 28.0 m for Victrix Pro 80 2ErP, 14.0 m for
Victrix Pro 100 2ErP and 8.5 m for Victrix Pro 120 2ErP. is
length is obtained considering the complete exhaust terminal, 1m
of 80 Ø pipe in exhaust, two 90° 80 Ø bends at the boiler outlet
to connect to the ducting system and two direction changes of
the exible tube inside the ue/technical slot.
1.20 FLUE EXHAUST WITH BOILERS IN CASCADE.
e boilers installed in cascade composed of any number between
2 and 5 boilers, can be manifolded to a unique ue exhaust pipe,
which ows into a ue.
Immergas supplied an appropriate and original ue exhaust system
separately to the boilers.
1.21 SYSTEM FILLING.
When the boiler has been connected, ll the system. Filling is
performed at low speed to ensure release of air bubbles in the
water via the boiler and heating system vents.
e boiler incorporates two automatic vent valves tted on the
circulator pump and on the condensing module. Check if the cap
is loose. Open the radiator vent valves. Close radiator vent valves
when only water escapes from them.
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 loosen-
ing the front cap and keeping the motor running. Screw
the cap back on aer the operation.
ATTENTION:
this boiler is not equipped with an
expansion vessel on the system. It is
mandatory to install a closed expansion
vessel to guarantee correct boiler operation.
e expansion vessel must comply with the
European Standards in force. e dimen-
sions of the expansion vessel depend on the
data relative to the central heating system.
Install a vessel whose capacity responds to
the requisites of the Standards in force (‘’R’’
collection).
