Applicable Flue Systems - Daikin D2CND024A4AB Installation Manual

Terminal position
B Below gutters, soil pipes or drain pipes
C Below eaves
D Below balconies or car front roofs
E From vertical drain pipes and soil pipe
F From internal or external corners
G Above ground, roof or balcony level
H From a surface facing a terminal
I From a terminal discharging towards
another terminal
J From an opening in a car port (e.g.
door, window) into a dwelling
K Vertically from a terminal on the same
wall
L Horizontally from a terminal on the
same wall
M Above an opening, air brick, opening
windows, etc.
N Horizontally to an opening, air brick,
opening windows, etc.
P Above roof level (to base terminal)
Q From an adjacent wall to flue
R From an adjacent opening window
S From another roof terminal
- From an external boundary. Note: If the
terminal is facing a boundary, it is
recommended that an anti-plume kit be
fitted.
T Terminals adjacent to windows or
openings on pitched and flat roofs: The
T1
flue should NOT penetrate this area.

NOTICE
The boiler manufacturer cannot be held responsible for
atmospheric conditions when siting flue terminals.
CAUTION
Once the flue system has been installed and the appliance
commissioned, the installer should observe the plume
direction. Particular attention should be drawn to plume
vapour reentering the gas boiler via the air intake. If this
occurs, it is highly possible the flue is fitted with a negative
pressure area and therefore a plume management kit
MUST be fitted.

Applicable flue systems

In this part, information about different flue systems are given. The
mounting instructions for correct installation of the flue systems are
included in the packaging of the flue parts as well as flue cutting
instructions where needed.
DANGER
Flue duct must incline 3° away from the unit, to allow the
condensate to drain back to the boiler and out of the
condensate drain. If the flue has an internal fall then please
follow instructions delivered with the flue parts.
INFORMATION
In the UK, only C13 and C33 flue types are allowed.

Type C13x (concentric flue system)
The boiler draws combustion air from outside via a concentric
150
coaxial pipe fitted to the external wall and expels flue gas to the
300
outside via the external wall.

60/100 flue length can be increased up to 17.9 metres (for D2T/
H*) / 14.1 metres (for D2C* )by adjusting the parameter C3 to 3.
Refer to servicing instructions for this operation.
Subtract equivalent length value of bends from the allowable flue
length value.
Flue length determination
Flue duct length (L) is measured from lip of the elbow to end of the
flue terminal.
