INSTALLATION OF THE HORIZONTAL AIR/FLUE DUCT (TOP OUTLET)
• Once the position of the flue exit
hole has been determined, the
hole should be cut through the
wall using a core drill of 127 mm
diameter.
Note: If access can be gained to
the proposed flue exit point from
outside the dwelling, the hole can
be cut with a 107 mm core drill
and the flue external wall seal
fitted from outside the dwelling.
• Measure the distance from the
outside face of the wall to the
centre of the fan outlet on the
boiler.
This is dimension A.
• (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).
• Cut the air duct and flue duct to
the lengths shown in figure 2.4.
• All flue sockets should point
towards the terminal.
• 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.
• If using the telescopic horizontal
air/flue duct and terminal accy.
303806 simply adjust the length
as shown in Fig 2.4. Secure the
air duct sections together by
drilling a 3 mm diameter hole
through the location hole in the
end of the outer air duct. (Ensure
that the drill does not pierce the
inner flue duct). Secure the air
ducts together using the screw
provided.
