Unpack the contents of carton leaving the combustion
box and mounting plate assembled on the base tray.
Place the outer case in a safe place until required.
Detach the fixing template from the packaging.
Remove the two wing nuts securing the
combustion box to the mounting plate.
Disengage the spring latch and lift the
combustion box away from the airbox. Place
the combustion box on its back.
Choose a flat vertical area to position the boiler,
making necessary allowances for required
minimum clearances. If fitting between wall
cupboards ensure that the minimum available width is
as shown.
Hold the wall template against the wall at the required
boiler location. Ensure that the top of the template is
level. The template represents the outer limits of the
appliance, plus the required minimum clearances.
NOTE: On gravity applications a clearance of 80mm
(3
1
/
8
in) is required from the top panel.
If fitting the appliance between or adjacent to kitchen
wall units, ensure that the line on the template
indicating the lower edge of the boiler is level with the
lower edge of the units and is correctly spaced.
If fitting the appliance in a compartment or cupboard
with suitable air vents (see Ventilation of
Compartments), ensure that the bottom edge of the
template is level with the lower edge of the units and
is correctly spaced.
Two holes are provided on the template to allow gas
and electrical supplies to be brought directly into the
boiler from the wall. The grommet provided must be
used when the electrical cable is routed through the
wall mounting plate.
Mark the position of the flue hole and four good
anchorage points. Where possible use the
uppermost and lowest fixing hole positions,
otherwise space the fixing holes as far
apart as possible. Mark gas and
electrical supply access holes if
required. Cut out hole for flue. Drill
anchorage holes 7mm (
9
/
32
in)
diameter by 63mm (2
l
/
2
in) deep to
accept wall plugs.
Make good internal masonry up to edges of
flue cut-out.
