Ravenheat CS 80 T Instructions For Use Installation And Servicing page 33

Cut a 105 mm diameter hole through the ceiling and/or
roof, at the point previously marked.
Fit a roof flashing slate to the roof, available from
Ravenheat. Insert the Vertical Flue terminal assembly
through the flashing slate from the outside.
Lift the boiler on the wall, locating onto the top two
fixing bolts. Tighten the two bolts using a spanner to
secure to the wall.
Measure the vertical distance between the top of the
flue and the bottom of the flue terminal assembly (fig.
21). The measurements should be taken from the outer
diameter of the flue.
NOTE: Where this length does not match any standard
combination of the extensions, only the
be cut to the required length (fig. 23).
When cutting both inner and outer ducts of the
extension, always cut on spigot side, and they must
be de-burred.

Starting at the appliance end, assemble the
extension duct sections, making each inner and
outer (flue) joint by inserting the spigot end into
the socket end of the next tube, making sure the
seal rings are correctly located (fig. 22). Make sure
that the entire flue is adequately supported. Use at
least one bracket for each extension used.
Ensure that all inner flue connections have a good
fit/seal, and that the space clips in each extension
are correctly positioned.
