10 Horizontal Rear Flue Installation
The Horizontal Rear flue - kit No A2009700 is
suitable for installations that require a flue
length from 190mm minimum to 667mm
maximum, without extensions, measurement
taken from the rear of the boiler to outside
wall face, see diagram 10.4 (3.).
If a longer flue length is required a 1metre
pipe extension can be used to give a
maximum flue length of no more than 1500,
measurement taken from the rear of the boiler
to outside wall face.
10.1 Horizontal Rear Flue kit of parts, refer to
diagram 10.1.
10.2 Cutting Rear Flue, refer to diagram 10.2.
Important Notes: After cutting ensure that there are no burrs.
10.3 Installation of Rear Flue assembly
• Fit rubber sealing collar (C) into groove at the outer end of the
flue assembly (A) and (B), see diagram 10.3.
• Fit flue assembly with attached rubber sealing collar into wall
from the outside with rubber sealing collar to the outside. Pull
assembly inwards to bring rubber sealing collar hard up against
external wall. The oposite end must exit the inner wall face by
40mm. see diagram 10.4. (1.)
• Fit the plastic internal flange (G) over the flue, push along the
pipe until engaged against internal wall, see diagram 10.4. (2.)
• Remove the backing from one of the wrap around self
adhesive seals (D) and carefully fit seal around the flue against
the internal flange at the inner wall face, trim to fit, see diagram
10.4. (2.)
• Remove the backing from the other wrap around self adhesive
seal (D) and carefully fit seal around the front end of the flue that
is extending 40mm from the inner wall face, trim to fit, see
diagram 10.4. (2.)
• Fit the ‘O’ ring (H) into the adaptor (F), apply a small amount
of silicone grease to the ‘O’ ring when fitting.
• Ease the adaptor (F) over the seals, see diagrams 10.4 (3.)
and 10.5.
• Important: Ensure that the flue if cut has no burrs that could
damage the ‘O’ ring.
• Fit the adaptor sealing gasket (E) to the adaptor.
