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 a loft
space.
• Two sets of steps should be used.
• Two people should share the lifting of the boiler up to the loft hatch,
where the boiler is entered into the loft space tilted and slid on its back
into the loft.

4.2 WALL MOUNTING TEMPLATE & FLUE OPENING
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 points 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,
additional mounting holes can be utilised if required.
The wall mounting template has been sized to allow for
minimum clearances of 5mm sides, 200mm base and
170mm above boiler case (which is 30mm above a
100mm diameter flue elbow).
REAR FLUE OUTLET
▶ The drawing opposite shows the boiler wall mounting template with
the flue centre lines of both the
100mm and 125mm flue systems.
3. Mark the centre line of the 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 the hole, preferably using a core drill.
SIDE OUTLET:
4. Mark from the centre line of the wall mounting template to the wall
that 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.
