10.4 -  Coaxial 
system: installation 
examples

When a coaxial vent and combustion 
air system is installed, fi gure 28, 
whether vertical or horizontal, it 
must be sloped 1/4 in/ft, 

(21 mm/m)

 

towards the boiler. 

CAUTION!!! Maintain the 

distances given in fi gure 29, 
between the vent terminal and the 
wall and also between the vent 
terminal and the ground level 
(snow line). 

Maintain 3ft distance also between 
the vent terminals of two or 
multiple boilers (see fi gure 29).

Figure 28 - Installation examples for 
the coaxial pipe 

(see section 10.2 for 

the reference of the numbers)

vent terminals of two boilers, in a vertical 
wall or in a roof
