INSTALLATION OF THE SE-DUCT FLUE
• Once the position of the flue exit
hole has been determined, the
hole should be cut through the
wall using a core drill of 120 mm
diameter. Ensure no debris enters
the Se-duct.
• Measure the distance from the
wall face (inside of the duct) to
the centre of the fan outlet on the
boiler.
This is dimension D.
• (Note: If using the top connection
spacer frame accessory with the
boilers with a rear exit, make an
additional 45 mm allowance for
the depth of the frame).
Length of Air duct:
• Cut the length of the air duct as
follows:
Length of air duct = D - 95 mm
Length of Flue duct:
• Cut the length of the flue duct as
follows:
Length of flue duct =
Length of air duct + 44 mm
• All flue sockets should point
towards the terminal.
• Ensure that the flue duct protrudes
by 40 mm into the Se-duct.
• When cutting the air and flue
ducts it is important to remove any
burrs with a file, this ensures easy
fitting of the ducts and prevents
any rough edges from damaging
the flue seals.
Care should be taken not to
scratch the white surface of the air
duct.
• If the installation requires the use
of air/flue duct extensions,
additional bends or elbows refer
to the sections on pages 25 – 27.
