WALL MOUNTING TEMPLATE
FLUE OPENING
CAUTION: Ensure there are no pipes,
electric cables, damp proof courses or
other hazards before drilling.
SAFETY:
All relevant safety precautions must be undertaken.
Protective clothing, footwear, gloves and safety
goggles must be worn as appropriate.
FIXING THE MOUNTING FRAME:
• The boiler template shows the relative
positions of the flue and the top and bottom
fixing of the mounting frame.
Fix the template to the wall in the desired
position (A).
Drill 4 holes for the wall mounting frame
through the template (2).
NOTE: The template has been sized to allow for
minimum clearances of 5mm sides,
200mm base and 30mm above a
Ø100mm flue elbow.
REAR FLUE OUTLET
• The drawing (B) opposite shows the boiler
template with the flue centre lines of both
the 100mm and 125mm flue systems.
Mark centreline of flue to be used (1); the
external diameter of the hole can also be
marked if required.
• If a Ø100mm diameter flue is to be used,
a125mm 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°.
• The 125mm Ø flue system will require the flue
to rise at an angle of 3°.
Drill hole using a core drill or similar.
SIDE OUTLET:
Mark from the centre line of the wall template
to the wall which the flue will pass through (3).
Allow for a rise of 52mm per metre length of
flue, to give a 3° angle.
Clear any debris from the site.
• A pre-filling kit 7 716 192 282 is available for
installations where the boiler will not be fitted
immediately to the heating system. This allows
the heating system and mains water connec-
tions to be filled and checked prior to boiler
installation.
This kit can be used in conjunction with the
optional filling loop 7 716 192 281(not sup-
plied with the boiler).
