13.5 Fitting the Flue – Low Level (Yellow) balanced
flue system
Remove both the burner access door, the upper access panel
(above the door) and also the access panel on the front face of the
oil boiler casing.
Fit the vertical flue extension section (supplied with the VortexAir
Hybrid).
To do so, locate the threaded stud (at the bottom of the extension
section) into the threaded socket in the centre of the flue outlet (on
the top of the boiler heat exchanger). See Figure 9-11.
Figure 13-12: Fitting the vertical flue extension section
Rotate the extension section to screw the stud into the socket
until the flange (at the bottom of the extension section) is firmly
compressing the circular neoprene gasket on the top of the heat
exchanger.
Depending on the location selected for the Hybrid boiler unit, either
inside or outside the building, remove and discard the circular
‘knock out’ section, as required.
•
For outdoor installation: Remove the ‘knock out’ from the end
face of the Hybrid boiler casing.
•
For indoor installation: Remove the ‘knock out’ from the rear
face of the Hybrid boiler casing.
Fit the boiler connection section
Unpack the flue kit and check the contents.
Take the boiler connector section and remove the self-tapping screw
holding the outer pipe and remove the outer pipe. See Figure 13-13.
