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 65mm 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
from the 100mm pipe ensuring any burrs are
removed. Using the cut-off piece of 100mm pipe
as a guide, mark and cut the same length of pipe
from the inner 60mm pipe (the 60mm should
always project past the 100mm pipe by 30mm).
Pass the concentric flue pipe through the previ-
ously 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 clamps, gaskets, and screws supplied,
secure the flue bend to the appliance flue spigot
and the flue terminal.
NOTE
Fit the internal (White) trim to the flue assembly
prior to connecting the flue pipe to the bend.

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 contained 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.
4.5.1
CONCENTRIC HORIZONTAL FLUE
(For concentric vertical flue, see section 4.5.2).
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.
