Flueing options
Rear external wall
False wall
Flue components:
- Direct A flue (R2731), or
- Direct B flue (R2732), or
- Direct flue (ASPDFK)
This flue configuration could
be up to 8.5 m long (no
bends).
Down and out
Flue components:
- Adaption flue (ASPKIT03)
- Coaxial pipe (ESPIPE900)
- Bend 2 x 45° (ESBEND x 1)
- Wall terminal (ESWTERM)
Flueing notes
For all installations an Arriva flue system
MUST BE used. Detailed flue instructions
are provided with Arriva flue kits.
Termination point
Flue is not to terminate under floors or in
a roof space.

A flue components:
- Adaption flue (ASPKIT03)
- Coaxial pipe (ESPIPE900)
- Roof cowl (ESROOFCOWL)
A flue configuration could have a
flue length of 7 m and contain one
90° bend—the 90° bend would be
the flue transition (ASPKIT03).
B flue components:
- Adaption flue kit (ASPKIT03)
- Coaxial pipe (ESPIPE900)
- Bend 2 x 45° (ESBEND x 1)
- Roof cowl (ESROOFCOWL)
B flue configuration could have a
flue length of 6.5 m and contain
two bends—the first 90° bend
would be the flue transition
(ASPKIT03), and the second 90°
bend would be two 45° bends
(ESBEND).
Condensate
A condensate trap is required for ALL
vertical flue installations to ensure
condensate generated during combustion
is trapped and prevented from entering
the chamber of the heater.
For horizontal, and down and out
installations, there must be a continuous
fall of at least 2°. This equates to
Flue
terminal
approximately 20 mm per metre to the
termination point to drain the condensate.
For direct flueing, direct flue kits A and B
have an inbuilt 2° fall.

Masonry
The Arriva must not be flued into natural
draft cavities.

A flue configuration could have

- Bends 2 x 90° (ESBEND x 2)
- Condensate trap (ESCONDK)
B flue configuration could have a
flue length of 6.5 m and contain
two 90° bends—the bends would
be the two 90° bends (ESBEND).
ASPDFK, remove terminal and use
on outside wall.
Down rating the appliance
For all Arriva flueing EXCEPT direct
flueing, the appliance must be down
rated (ensures optimum performance
of the fan) as per the instructions on the
commissioning sheet.
Maximum flue length and number of
bends
•
Max. flue length - 8.5 m
•
Max. number of bends - three
One 90° bend equals 1 m. For every 90°
bend the overall length must be reduced
by 1 m. For example if an installation has
three 90° bends, the maximum flue length
can be 5.5 m. The flue transition for all
flueing installations, excluding direct
horizontal flueing, is counted a 90° bend.
