Gas Balanced Flue Guide - Euroheat

Balanced Flue Systems
A balanced flue system utilizes a double concentric pipe, the inner one taking away the products of combustion
and the outer one bringing the air supply to the stove. This system allows a gas stove to be installed where no
flue exists, and because the flue needs very little vertical height to operate, it is often possible to route the flue
through the room wall to the outside.
With all the air necessary for combustion being supplied through the outer pipe directly from the outside, the
room in which the stove is installed needs no ventilation specifically for the stove.
The balanced flue system has been designed to give a huge range of installation options, terminating either
horizontally or vertically, as illustrated in the diagram below.
Deciding on which form the balanced flue should take will very much be constrained by the termination of the
flue. Building Regulations lay out definitive guide lines for where a flue can terminate, see the diagram later in
this document, and if the building is listed there may be constraints on the position of any terminal and advice
should be sort from the appropriate regulatory authority.
