4.5.1.1 FITTING THE HORIZONTAL FLUE KIT (enclo-
sure applications)
Determine the route of the flue pipe and carefully
measure the distance from the centre of the
appliance flue outlet to the outside face of the
enclosure (dimension ‘X’ see fig. 7). Ensure the
inner (60mm) pipe is fully inserted into the outer
(100mm) pipe (when the inner pipe is fully in-
serted, it stands proud of the outer pipe by
7.5mm). Add 32mm to dimension ‘X’ to give the
overall flue length (dimension ‘Y’).
NOTE
The standard horizontal flue kit (part no. 2359029)
is suitable for a distance (dimension ‘Y’) of up to
865mm.
The telescopic flue kit (part no. 2359119) is
suitable for a distance (dimension ’Y’) of up to
600mm.
Dimension ‘Y’ is measured from the end of the
terminal to the end of the outer (100mm) pipe.
The internal trim should be fitted to the flue pipe
before connection of the 90º bend
If the horizontal flue kit (2359029) requires to be
cut to the correct size (dimension ‘Y’), you must
ensure that the inner (60mm) pipe stands proud
of the outer (100mm) pipe by 7.5mm (see fig. 8).
Ensure any burrs are filed or removed and that
any seals are located properly before assembly.
The telescopic flue terminal should be adjusted to
the appropriate length and then fixed using the
securing screw supplied.
The knock-out panel should now be removed to
allow passage of the flue pipe.
4.5.1.2 STANDARD FLUE KIT (2359029)
Hold the inner (60mm) pipe of the terminal as-
sembly and connect to the push-fit end of the
90º bend (supplied) using a twisting action. In-
sert the assembled flue through the enclosure
hole. Using the clips & screws supplied, connect
the flue assembly to the boiler, ensuring that the
terminal protrudes past the outside surface of
the enclosure by the correct length (135mm).
4.5.1.3 TELESCOPIC FLUE KIT (2359119)
Connect the 60mm push-fit connection of the flue
bend (supplied) to the telescopic flue assembly
using a twisting action. Insert the assembled flue
through the enclosure hole. Using the clips &
screws supplied, connect the flue assembly to
the boiler, ensuring that the terminal protrudes
past the outside surface of the enclosure by the
correct length (135mm).

4.5.1.4 EXTERNAL APPLICATIONS WITHOUT THE
ENCLOSURE
Vokera recommend that the B22 kit is used on
Rain boilers that are installed external to the
property or dwelling (see fig 8A & 8B).
●
Insert the required flue restrictor ring (L) into the
flue spigot (if not already fitted)
●
Insert the exhaust connection manifold onto
the appliance flue outlet (N)
●
Using the hole in the exhaust connection mani-
fold as a guide, drill a 3mm hole in the appliance
flue spigot and secure the exhaust manifold
connection to the flue spigot using the screw
provided
●
Place the silicone seal (supplied with twin
adapter kit) over the rim of the exhaust connec-
tion manifold
●
Remove the required blanking plate (‘M’ - lo-
cated to the left and right of the appliance flue
outlet) and - using the same screws - install the
air baffle
●
Using the hole in the exhaust connection mani-
fold as a guide, drill a 3mm hole in the appliance
flue spigot and secure the exhaust manifold
connection to the flue spigot using the screw
provided
●
Connect the exhaust flue outlet terminal to the
exhaust elbow and secure to the wall with the
wall bracket (supplied)
●
Insert the air inlet terminal to the air inlet elbow.
