SECTION 4
INSTALLATION
4.1
DELIVERY
Due to the weight of the appliance it may be
necessary for two people to lift and attach the
appliance to its mounting. The appliance is con-
tained within a heavy-duty cardboard carton. Lay
the carton on the floor with the writing the correct
way up.
4.2
CONTENTS
Contained within the carton is:
●
the boiler
●
the wall bracket
●
appliance template
●
an accessories pack containing appliance serv-
ice connections and washers
●
the instruction pack containing the installation
& servicing instructions, user instructions,
Benchmark logbook, guarantee registration card
and a 3-amp fuse.
4.3
UNPACKING
At the top of the carton pull both sides open - do
not use a knife - unfold the rest of the carton from
around the appliance, carefully remove all pro-
tective packaging from the appliance, and lay the
accessories etc. to one side. Protective gloves
should be used to lift the appliance, the appliance
back-frame should be used for lifting points.
4.4
PREPARATION FOR MOUNTING THE APPLI-
ANCE
The appliance should be mounted on a smooth,
vertical, non-combustible surface, which must be
capable of supporting the full weight of the appli-
ance. Care should be exercised when determin-
ing the position of the appliance with respect to
hidden obstructions such as pipes, cables, etc.
When the position of the appliance has been
decided - using the template supplied - carefully
mark the position of the wall- mounting bracket
(see fig. 6) and flue-hole (if applicable).
4.5
FITTING THE FLUE
The top flue outlet permits both horizontal and
vertical flue applications to be considered, alter-
natively, the Vokera twin flue system can be
utilised if longer flue runs are required.
4.5.1
CONCENTRIC HORIZONTAL FLUE
(For concentric vertical flue, see section 4.5.2).
(For twin flue applications, see section 4.5.3).
The appliance can be used with either the Vokera
condensing 60/100mm concentric flue system or
the optional 80/125mm concentric flue system.
NOTE
These instructions relate
only
to the Vokera con-
densing 60/100mm concentric flue system. For
specific details on the installation of the 80/125mm
concentric flue system please refer to the instruc-
tions supplied with the 80/125mm terminal.
The appliance flue outlet elbow can be rotated
through 360º on its vertical axis
.
In addition the
flue may be extended from the outlet elbow in the
horizontal plane (see 2.9). A reduction must also
be made to the maximum length (see table
below) when additional bends are used.
Bend
Reduction in maximum flue length for each bend
45º bend
0.5 metre
90º bend
1.0 metre
Reduction for additional bends
Using the template provided, mark and drill a
115mm hole for the passage of the flue pipe. The
hole should be drilled level to ensure any con-
dense fluid that forms will drain back to the boiler.
The fixing holes for the wall-mounting bracket
should now be drilled and plugged, an appropri-
ate 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.
FITTING THE HORIZONTAL FLUE KIT
Carefully measure the distance from the centre of
the appliance flue outlet to the edge of the fin-
ished outside wall (dimension X). Add 45mm to
dimension X to give you Dimension Y (see fig 7A).
Measure dimension Y from the terminal end of
the concentric flue pipe and cut off the excess
ensuring any burrs are removed. Pass the con-
centric flue pipe through the previously drilled
hole. Fit the flue bend to the boiler flue outlet and
insert the concentric flue pipe into the flue bend
ensuring the correct seal is made.
Using the clamp, gasket, and screws supplied,
secure the flue bend to the appliance flue spigot.
The 60mm M & F adaptor (supplied with the flue
kit) should be discarded.
NOTE
Fit the internal (White) trim to the flue assembly
prior to connecting the flue pipe to the bend.
You must ensure that the entire flue system is
properly supported and connected.
Seal the flue assembly to the wall using cement
or a suitable alternative that will provide satisfac-
tory weatherproofing. The exterior trim (Black)
can now be fitted.
