1.8   IMMERGAS FLUE SYSTEMS.

Immergas supplies various solutions separately 

from the boilers regarding the installation of 

air intake terminals and flue exhaust, which are 

fundamental for boiler operation.

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 tracts longer than 40 cm, without suitable 

protection from UV rays and other atmos-

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

tion mark and special distinctive marking 

bearing the note: “only for condensing boilers”.

•  Resistance factors and equivalent lengths. Each 

flue component has a 

Resistance Factor

 based 

on experimental tests and specified in the table 

below. The Resistance Factor for individual 

components is independent from the type of 

boiler on which it is installed and has a dimen-

sionless size. It is however, conditioned by the 

temperature of the fluids that pass through the 

pipe and therefore, varies according to applica-

tions for air intake or flue exhaust. Each single 

component has a resistance corresponding to 

a certain length in metres of pipe of the same 

diameter; the so-called 

equivalent length

can be obtained from the ratio between the 

relative Resistance Factors. 

All boilers have an 

experimentally obtainable maximum Resistance 

Factor equal to 100.

 The maximum Resistance 

Factor allowed corresponds to the resistance 

encountered with the maximum allowed pipe 

length for each type of Terminal Kit. This 

information allows calculations to be made to 

verify the possibility of setting up various flue 

configurations.

• 

Positioning the gaskets (black) for “green 

range” flue systems.

 Position the gasket cor-

rectly (for bends and extensions) (Fig. 1-7):

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

sions;

 N.B.:

 if component lubrication (already car-

ried out by the manufacturer) is not sufficient, 

remove the residual lubricant using a dry cloth, 

then to ease fitting coat the parts with talc, sup-

plied in the kit.

• 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 side (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 mini-

mum inclination of 3% must be maintained and 

a section clip with pin must be installed every 

3 metres.
