IMPORTANT HANDLING INSTRUCTIONS:
• It is advised that two people are used to carry the carton from the van
to the point of delivery.
• Once the carton has been delivered, the outer carton is removed first.
Care should be taken when releasing the straps. If a sharp implement
is used make sure the outer carton is not pierced and that the
implement is used in such a way so that it may not cause personal
injury.
• All sharp objects must be covered or the blade retracted after use and
put away in a safe place.
Care should be taken when lifting the boiler from the base and the
proper technique for safe lifting of any heavy object should be strictly
observed.

Additional requirements for roof space installation:
• The boiler should be first unpacked before ascending ladder to loft

NOTICE:

4.2 WALL MOUNTING TEMPLATE & FLUE OPENINGS
WARNING: BEFORE DRILLING:
Ensure that there are no pipes, electrical cables,
damp proof courses or other hazards.
SAFETY:
All relevant safety precautions must be undertaken. Protective clothing,
footwear, gloves and safety goggles must be worn as appropriate.
FIXING THE WALL MOUNTING FRAME:
▶ The boiler wall mounting template shows the relative positions of the
flue and the top and bottom fixing of the wall mounting frame.
1. Fix the wall mounting template to the wall in the desired position.
2. Drill 4 holes for the wall mounting frame through the template.
The wall mounting template has been sized to allow for
minimum clearances of 5mm sides, 200mm base and
30mm above a 100mm diameter flue elbow.
REAR FLUE OUTLET
▶ The figure 22 shows the boiler wall mounting template with the flue
centre lines of both the 100mm and 125mm flue systems.
3. Mark centre line of flue to be used (3); the external diameter of the
hole can also be marked if required.
▶ If a 100mm diameter flue is to be used, a 125mm diameter hole is
required. However, if using the weather sealing collar by pushing it
through from inside the property, then a 150mm diameter hole is
required to accommodate this.
▶ The flue turret of the 100mm flue has an in-built 3° angle.
▶ If extensions are to be added then the complete flue must rise at an
angle of 3°.
▶ Drill hole using a core drill or similar.
SIDE OUTLET:
4. Mark from the centre line of the wall mounting template to the wall
which the flue will pass through (4).
▶ Allow for a rise of 52mm per metre length of flue, to give a 3° angle.
▶ Clear any debris from the site.
An optional filling loop: 7 716 192 281 is available to fill
the system (not supplied with the boiler).
