1.12 IMMERGAS FLUE SYSTEMS.

Immergas can supply various solutions for flue-

ing and air supply.

Attention: the boiler must be installed ex-

clusively with an original Immergas “Green 

Range” inspectionable air intake system and 

fumes extraction system made of plastic, with 

the exception of the C6 configuration, as re-

quired by the regulations in force.
The plastic pipes cannot be installed outdoors, 

for lengths longer than 40 cm, without suitable 

protection from UV rays and other atmos-

pheric agents.
This system can be identified by an identifi-

cation mark and special distinctive marking 

bearing the note: “only for condensing boilers”.

• 

Configuration type B, open chamber and fan 

assisted. 

The boiler leaves the factory with type 

“B

23

” configuration.

  Air intake takes place directly from the envi-

ronment in which the boiler is installed via 

relevant slots made in the back of the boiler 

and flue exhaust in the individual flue or to the 

outside. Boiler with this type of configuration 

are classified as type B

23

 (in accordance with 

standard EN 297 and relative standards in 

force).

  With this configuration:
  -  air intake takes place directly from the room 

in which the appliance is installed;

  -  the flue exhaust must be connected to its own 

individual flue or channelled directly into the 

external atmosphere.

  - Type B open chamber boilers must not be 

installed in places where commercial, artisan 

or industrial activities take place, which use 

products that may develop volatile vapours 

or substances (e.g. acid vapours, glues, paints, 

solvents, combustibles, etc.), as well as dusts 

(e.g. dust deriving from the working of wood, 

coal fines, cement, etc.), which may be harm-

ful for the components of the appliance and 

jeopardise operation.

• 

Type C configuration, sealed chamber and 

fan assisted. 

The boiler leaves the factory with 

"B

23

" configuration, to change the configuration 

of the boiler to type "C" (sealed chamber and 

fan assisted), disassemble the 80 Ø adapter, the 

bracket and the gasket present on the boiler 

cover and install the designated flue.

• Coupling extension pipes and concentric 

elbows. To install push-fitting extensions with 

other elements of the flue, proceed as follows: 

Install the concentric pipe or elbow with the 

male side (smooth) on the female section 

(with lip seal) to the end stop on the previously 

installed element in order to ensure sealing 

efficiency of the coupling.

Attention:

 if the exhaust terminal and/or 

concentric extension pipe needs shortening, 

consider that the internal duct must always 

protrude by 5 mm with respect to the external 

duct.

• 

N.B.:

 for safety purposes, do not obstruct the 

boiler intake-exhaust terminal, even temporar-

ily.

• 

N.B.:

 when installing horizontal pipes, a min-

imum inclination of 3% must be maintained 

and a section clamp with pin must be installed 

every 3 metres.

• 

Maximum extension. 

Each individual compo-

nent has a resistance corresponding to a certain 

length in metres of pipe with the same diameter 

(par. 1.13). With installations that involve using 

various types of parts, deduct the length of 

the added part from the maximum admissible 

length of the kit.

  Example: if you need to add a 90° bend to 

a concentric system 125 Ø you will need to 

deduct 1.9 m from the maximum admissible 

length.

• 

Positioning of the gaskets (black) for “green 

range” flue extraction systems.

 Position the 

gasket correctly (for bends and extensions) 

(Fig. 1-9):

  - gasket (A) with notches, to use for bends;
  -  gasket (B) without notches, to use for exten-

sions;

 N.B.:

 if component lubrication (already carried 

out by the manufacturer) is not sufficient, re-

move the residual lubricant using a dry cloth, 

then to ease fitting coat the parts with talc, 

supplied in the kit.
