noTe: For assembly reasons do not shorten any air duct to a
length of less than 100mm. If necessary shorten two adjacent
extensions to achieve the overall required length.
noTe: For installations where there is insufficient movement
to allow fitting of the flue into flue outlet, a sliding sleeve is
available Part No. 0020104558. When using the sliding sleeve
both the air and flue ducts of the last extension must be
shortened by a further 85mm.
7.4 Installing the sliding sleeve
Push the sliding sleeve (1) over the cut end of the flue duct (2).
Pull back the sliding sleeve so that it engages into the socket
(3) of the boiler (4). Ensure that the sliding sleeve penetrates
the socket such that there is at least 20 mm engagement at
both ends of the sliding sleeve. Fit the air duct clamp (7) over
the air ducts (5 and 6) of the extension/terminal and boiler
outlet. Close the snap clamp.
Drill two holes 3mm diameter through the air duct clamp (7) (the
centre of the holes should be 6mm from the edge of the clamp).
Ensure that the drill does not penetrate the inner flue duct.
Screw the air duct clamp to the air duct of the sleeve using the
screws provided.
Complete the installation of the flue as detailed in these
instructions.
7.1 Top Horizontal standard flue Ø80/125
Refer to diagram 1 and check the contents of your kit.
Make sure you have all the necessary components before
proceeding with the installation.
7.2 flue length and Terminal Position
Refer to your Installation instructions supplied with the
appliance to confirm the flue length available and location of the
flue terminal, then proceed as follows:
• Secure the flue adapter in position on top of the appliance
with four screws supplied.
noTe: Make sure the nib fits into the locating slot in the
appliance casing to ensure correct orientation.
• With the flue elbow temporarily fitted, measure the distance
from the external wall to the elbow.
SIDE FLUE
* ‘Y’
• If the measurement ‘Y’ exceeds the achievable flue length,
960mm. then the appropriate length of extension pipe is
required.
7.3 extension cutting
• Separate the flue duct from the terminal by twisting to
release from the securing catch inside the air/flue duct
• When cutting, cut equal amounts off the air duct and flue
duct.
• When joining extensions leave a gap of 5mm between
each air duct this will leave a correct flue duct connection of
30mm.
