3.5.2 Preparation
• Determine the installation site for the boiler with ref-
erence to the installation and servicing instructions
supplied with the boiler.
• Ensure that all installation and service clearances are
available and that the boiler flue can be installed as
detailed in these instructions.
• Fix the paper template, supplied with the boiler, to the
wall ensuring that the centreline of the template is
vertical using a plumbline or spirit level.
3.5.3 Side
flue
installations
• For installations where the air/flue duct is to be in-
stalled to the side, the position of the flue exit hole
can be determined as follows:

* = 190 mm ecoTEC exclusive combination
* = 176 mm ecoTEC plus open vent
* = 125 mm ecoTEC plus system & combination
* = 323 mm ecoTEC plus 937
• Identify the correct measurement as shown in fig. 3.7,
carefully measure the distance from the bottom cen-
tre of the boiler hanging bracket (centreline of the
two lower hanging bracket fixing holes). This gives the
position of the centreline of the 127 mm flue elbow
and adaptor when installed.
• The position of the flue exit hole can be determined
by carefully levelling across the wall from this mark.

• The position of the flue exit hole should allow the flue
to be installed with an upwards slope towards the ter-
minal of approximately 3°
±
1°, equivalent to
50 mm
±
20 mm rise per metre of flue length. Calcu-
late the required rise according to the flue length and
mark the position of the flue exithole (fig 3.8).
Optional Concentric System Ø 80/125 3
