Cut a 105 mm diameter hole through the ceiling
and/or roof, at the point previously marked.
Fit a roof flashing sleeve (fig. 33 item 7) to the roof,
available from Ravenheat Manufacturing.
Insert the Vertical Flue terminal assembly through
the flashing plate from the outside.
Fix the appliance to the wall, locating onto the
hanging bracket.
Measure the vertical distance between the top of
the flue (Fig. 31) and the bottom of the flue terminal
assembly (Fig. 32). 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, they can
be cut to the required length (Fig. 32).
When cutting both inner and outer ducts of the
extension, always cut on spigot side, and they must
be de-burred.
