Side and Rear Flue
Provided that the flue hole is cut accurately, e.g. with a core drill,
the flue can be installed from inside the building where wall
thicknesses do not exceed 600mm. Where the space into which
the boiler is going to be installed is less than the length of flue
required the flue must be fitted from the outside.
