11 FLUE SYSTEMS
A comprehensive range of flue kits are available from
Caradon Ideal Limited. Examples of horizontal and vertical
concentric, twin pipe and open flue options are demonstrated
on the following pages. Tables are provided with these
examples, giving the maximum extensions which may be
added. The flue lengths achievable without any extensions
are also provided.
For horizontal flues: this is the distance from the flue outlet
centre line on the boiler to the outside wall.
For vertical flue: this is the distance from the top of the boiler
case to the aperture in the weather collar.
If elbows are to be used, then the equivalent length of that
fitting (see page 17) must be subtracted from the maximum
flue extensions allowed for that flue option.
Note: Horizontal terminal resistance includes 1 x 90º elbow.
Worked examples are shown on page 5, 17 and 18.
Alternatively the resistances of flue components are given on
page 17, together with the maximum flue resistance each
boiler can work against. These may be used to calculate the
total flue resistance of the system, and to determine if they are
acceptable to run on the boiler.
