14 Dimensions for cutting
flue hole
Apply a chamfered edge to the cut ends,
apply silicone lubricant and insert through
the wall and into the flue/air socket. The
overall projection of the finished pipe should
leave the air holes 20mm clear of the
surrounding wall as per figure 15.
NOTE: When fitted, it is important to
position the flue outlet with a slight fall so
that the 80mm flue pipe is sloped back
towards the boiler.
Failure to observe this requirement will
result in condensate running out of the flue
pipe and over the external brickwork
causing possible staining and or freezing.
Installed correctly the flue pipe will self drain
back through the boilers internal
condensate route.
Make good to internal and external walls
and fix an external stainless steel terminal
guard if required.

Wall Terminal
The final location of the Flue Outlet terminal
should comply with figure 23 and table 8.
In certain circumstances the location of the
boiler may leave the flue outlet in a position
that does not comply with figure 23, or
where pluming is a nuisance.
The eco hometec flue system has been
designed to overcome this and the 80mm
P.P.S. flue pipe may be simply re-routed to
terminate in a more suitable location. To
do this simply remove the 80mm stainless
steel flue grill and insert either a 90
0
or 45
0
bend
Note: two 45
0
may be used to form a swan
neck returning the flue pipe back to the wall
for clipping.
Route the pipe to the desired location and
terminate with a suitable bend to direct the
flue gases away from the wall or any
obstruction. When you are satisfied that
the location complies with the requirements
of figure 23 replace the stainless steel
80mm flue grill..
Alternatively a 90
0
terminal fitting may be
purchased from eco hometec and the flue
routed vertically.
