4.1.1

Select position of boiler

Refer to section 'Boiler location' for information regard-
ing the appliance location. In general the boiler must be
positioned such that:
• There is adequate space around the boiler for service
and maintenance
• The boiler can be correctly flued, i.e. the flue terminal
position is located in accordance with these instruc-
tions and the air/flue duct can be installed in accord-
ance with the flue installation instructions supplied.
• All necessary pipework can be connected, including
the pressure relief valve and condensate drain.

4.1.2 Unpack the boiler

To unpack the boiler, cut both plastic carton straps, open
box and lift out the polystyrene top packing. Lift the
cardboard box upwards.
Note
Care should be taken not to scratch the white
surface of the boiler casing

4.1.3 Using assembly templates

• Adjust the assembly template provided with the appli-
ance with the assembly spot vertically and fix the tem-
plate.
The template shows:
- the position of the fixing holes for the appliance hold-
er,
- the position of the connecting pipe and
- the position of the flue pipe for the horizontal wall
lead-in directly above the appliance.
• Mark the position of the fixing holes and drill two
holes with Ø 8 mm for the plugs.
• If you want to guide the flue pipe horizontally directly
above the appliance through the outer wall, mark the
opening for the wall lead-in on the wall. While install-
ing the flue pipe, follow the enclosed assembly instruc-
tions, which also describe other possible pipe layouts
for the flue system.
• Remove the assembly template from the wall.
