INSTALLATION OF THE TELESCOPIC 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 125 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 (fig. 3.16).
This is dimension A.
• Adjust the air duct and flue duct
to the lengths shown in (fig.
3.17).
• 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 (
1 ). (Ensure that the drill does
not pierce the inner flue duct).
Secure the air ducts together using
the screw (
1 ) provided. Place the
adhesive tape ( 2 ) across the gap
in the telescopic extensions.
(fig. 3.17)
• All flue sockets should point
towards the terminal.
• 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 31 - 35.
