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 pipes to the boiler.
Also clearances around the appliance.
Fix the template to the wall in the desired
position (
A
).
Mark the clearance around the boiler and the
position of gas and system pipes (
2
) and
(
3
).
Drill 4 holes for the wall mounting plate
through the template.
Drill 2 holes for bottom fixing screws.
Drill hole for flue duct through the wall.
NOTE: The template has been sized
to allow for minimum clearances of
5mm sides, 200mm base and
30mm above a Ø100 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 centre-line of flue to be used (
1
).
•
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
(
4
).
Allow for a rise of 52mm per metre length of
flue, to give a 3° angle.
Clear any debris from the site.
CAUTION: Ensure there are no pipes,
electric cables, damp proof courses or
other hazards before drilling.
