FLUE SYSTEMS
A comprehensive range of ue kits are available from
Ideal Stelrad Group. Examples of horizontal and vertical
concentric and open ue options are demonstrated on the
following pages. Tables are provided with these examples,
giving the maximum extensions which may be added. The ue
lengths achievable without any extensions are also provided.
For horizontal ues: this is the distance from the ue outlet
centre line on the boiler to the outside wall. Horizontal ues are
not available for Evomax 150.
For vertical ue: 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
tting (see page 17) must be subtracted from the maximum ue
extensions allowed for that ue option.
Note: Horizontal terminal resistance includes 1 x 90
o
elbow.
Worked examples are shown on page 17 and 18.
Alternatively the resistances of ue components are given
on page 16, together with the maximum ue resistance each
boiler can work against. These may be used to calculate the
total ue resistance of the system, and to determine if they are
acceptable to run on the boiler.
Multiple boilers may be installed with a common ue header
(not supplied by Ideal Heating). The ue system should be
designed and supplied by a specialist ue company. BS 6644
and IGE UP/10 provide guidance on design and the drainage
of condensate from ue stack and headers. Condensate from
a ue stack and header must be collected and drained before
entering the boiler.
Note: See Frame 18 for elbow equivalent lengths.
