1.
GENERAL
Note: These flues MUST ONLY be used with the Alpha Condensing boilers.
a.
The Alpha Easy-Flue is suitable for straight horizontal flues only and can be extended up to the maximum lengths
given in Section 4.
b.
The Alpha CD Easy-Flue is suitable for providing two options for management of the exhaust flue gas/plume emitted
from the terminal. They are:-
i. Divert the plume at 45° by altering the terminal of the the Easy-Flue.
ii. Extend the inner flue duct by using Plume Management accessories to re-locate the terminal to an area where the
plume will not cause a nuisance.
Note:
When fitting plume management accessories, ensure there is always a
slope towards the Easy-Flue assembly in the wall by a minimum of 25-30 mm per metre and there is no part of the
pipework where condensate/rain will collect.
Refer to Section 5 for full details.
c.
The Easy-Flue includes a 90° bend, (no separate 90° bend is required).
d.
Ensure the Easy-Flue outer duct is installed horizontally (please note that the Easy-Flue inner duct already has a pre-
determined slope towards the boiler for condensate to run back towards the boiler) and when extending the flue with flue
extensions, these flue extensions must be installed with a slope downwards towards the boiler by a minimum of 25-30
mm per metre.
e.
The flue system must be installed in accordance with BS 5440:1.
f.
The boiler must be installed in accordance with the installation instructions supplied with the Alpha condensing boiler.
g.
The CD Easy-Flues are suitable for use in the flue length ranges shown in the tables below.
Note:
Where the length is less than the minimum or more than the maximum, refer to Section 4.
