Before proceeding with installation check the con-
tents of the RAVENHEAT VERTICAL FLUE KIT,
comprising of the following pieces:
- 1 RAVENHEAT VERTICAL FLUE
complete with terminal assembly (for ver-
tical flue application).
-Additional 1000 mm (approx) Flue Exten-
sion pieces as necessary, each exten-
sion is provided with flue centering bracket.
- One box containing straight header.
Proceed with installation as detailed in section 5 up
to 5.5.1., ignoring all references to horizontal flue
installations.
Use adhesive tape to attach the template to the wall,
making sure that the centre line is vertical and that
the flue centre line is virtually below the point at
which the flue will exit the roof.
- Ensure that the maximum permissible
flue length is not exceeded (Fig. 42).
- Mark the four boiler fastening holes on
the wall.
- Detach the template from the wall.
- Use a 10 mm dia. drill to make the 4 boil-
er securing holes. Insert plastic expan-
sion plugs (Fig. 29).
- Screw in the two upper coach bolts leav-
ing them about 10 mm out from the wall
to enable the boiler to be located on the
wall.
- Position the straight header on the top of
the appliance (Fig. 43) item 6, and
ensure that the gasket is correctly fitted.
Important: Make sure that the flue header dia 60 mm
duct is inserted fully onto the fan spigot.

Cut a 105 mm diameter hole through the ceiling
and/or roof, at the point previously marked.
Fit a roof flashing sleeve (43 Fig. 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 top
coach bolts. Fit the two lower coach bolts and tighten
all four securing bolts.
Measure the vertical distance between the top of the
flue and the bottom of the flue terminal assembly.
The measurements should be taken from the outer
diameter of the flue (Fig. 41).
NOTE: Where this length does not match any stan-
dard combination of the extensions, extension can
be cut to the required length (Fig. 44).
When cutting both inner and outer ducts of the
extension, always cut on spigot side, and they must
be de-burred.
