4.5.2 CONCENTRIC VERTICAL FLUE
Using fig.20 as a reference, cut a 110mm diameter hole in
the roof and/or ceiling to facilitate the route of the vertical flue
system.
NOTE:
ensure that the top of the appliance - if already
in position - is covered and protected from the possibility of any
dust or debris falling or entering the appliance via the flue outlet.
Fit the appropriate flashing to the roof and insert the vertical flue
terminal through the flashing from outside, ensuring that the
collar of the terminal is located over the outlet of the flashing.
The fixing holes for the appliance wall mounting bracket should
now be drilled and plugged. An appropriate type and quantity
of fixing should be used to ensure that the bracket is mounted
securely. Once the bracket has been secured to the wall, mount
the appliance onto the bracket.
If the vertical flue system requires additional extensions or bends,
connect these to the vertical terminal, ensuring the following:
- the maximum permitted flue length is not exceeded
- reductions to the maximum flue length have been made for
any bends that are used on the vertical flue system
- any horizontal sections of the flue system, incorporate a
3-degree fallback to the appliance
- the entire flue system is fully supported and secured using
the appropriate brackets
- if/when an extension is cut to a shorter length, ensure that
the excess length is cut from the plain end of the extension,
and that any burrs or rough edges are removed
- all seals are properly located before assembling or connecting
the flue system.
IMPORTANT:
The VX flue terminal is supplied with a sachet of
silicone lubricant; smear a small amount of the lubricant around
both inner and outer connections, at both ends of the vertical
flue connector (supplied with the VX terminal).
NOTE:
The appliance incorporates a ‘click-fit’ flue connection
(see fig. 19). Ensure that both screws ‘
C
’ (fig. 12) on the ‘click-fit’
have been slackened off. Ensure that the connector is correctly
aligned with the ‘click-fit’ and insert it into the ‘click-fit’ until it
clicks into position (this is when the tabs at points ‘
A
’ are located
in the groove of the vertical flue connector - see fig. 19). Both
screws (
C
) should now be tightened.
NOTE:
If more convenient, the vertical flue connector can be
attached to the vertical flue terminal/extension before connecting
it to the appliance.
NOTE
Additional bends and/or extensions can be connected to the
terminal connector if desired, however if additional bends are
fitted, a reduction must be made to the maximum flue length
(see table below).
