MOUNTING THE APPLIANCE
Refer to Figure 10.
a)
Lift the appliance into position approximately 10 mm above
the top of the wall mounting plate and use the side wings on the
plate to locate the appliance in a horizontal direction. Then
carefully lower the appliance, ensuring that the top locating rail is
securely engaged.
b)
Connect the central heating system pipes to the central
heating flow and return pipes on the boiler.

4.1
UNPACKING THE APPLIANCE
The appliance is supplied in one box. Flue kits are provided
separately, the various flue kits available as described in sections
2.5 - 2.7. If the appliance is to be installed without access to an
external wall, a wall liner kit is also required.
Unpack the boxes and check the contents:
●
Complete appliance
●
Paper wall mounting template
●
Wall mounting plate
●
Installation and Servicing Instruction
●
User's Instructions
●
Benchmark book
●
Hardware pack containing:
50 mm x No 10 wood screw - 4 off
Wall plug to suit - 4 off
22mm street elbow - 2 off
22mm nuts & olive - 2 off
65mm x 10mm coachbolt - 2 off
Rawl Plug to suit - 2 off
Before installing the appliance, check that the chosen location is
suitable (section 3.2) and that the requirements for flue position
(section 3.3) and minimum clearances (Figure 1b) are satisfied.
Manual Handling Note: During the appliance
installation it will be necessary to employ caution and
assistance whilst lifting, as the appliance exceeds the
recommended weight for a one-man lift. Take care to
avoid trip hazards, slippery or wet surfaces.
4.2
PREPARING THE WALL
a)
Fix the paper template in the required position (ensuring that
the necessary clearances are achieved). Ensure squareness by
hanging a plumb line.
b)
Mark the position of the wall mounting plate-fixing holes (4).
c)
Mark the position of the flue outlet. For side flue installation
extend the flue centre line on to the sidewall, where the flue
length exceeds 775 mm, a flue slope angle of 2.5° needs to be
taken into account. Refer to Figure 9. Remove the paper template.
d)
Cut the hole in the wall for the air/flue duct (preferably with
a core-boring tool). The hole must be horizontal and not be less
than 100 mm in diameter. If the hole is not accessible from
outside, its minimum diameter must be sufficient to allow insertion
of the wall liner (130 mm, 5in). The wall liner is available as an
optional extra and must be sealed in position with mortar (or
equivalent).
e)
Drill the four fixing holes using a 6mm drill and insert the wall
plugs provided.
f)
Hang the wall mounting plate using four fixing screws,
ensuring that it is level.
Pipe work may be routed from above or below the
appliance as required.

COMBUSTION CHAMBER &
Inspect the inside of the combustion chamber for debris. If
necessary, clean the inside of the tubes with a soft brush. Do not
brush the insulation at the rear, check the integrity of the
combustion chamber insulation panels, if damaged they will
require replacement.
6.6
CONDENSATE DRAIN
The condensate Drain has a removable cap, Figure 30, which
allows the removal of debris that may be caught within it. Place
a bowl under the cap to catch the condensate and remove the
cap. Any debris inside will be expelled at this point. Replace the
cap ensuring a good seal is made. Discard the condensate and
debris.
