The vertical flue kit is intended for use where
a horizontal flue outlet is not possible or desired.
The vertical flue can be used either with a flat roof
or a pitched roof (maximum pitch 60°).
Where a straight vertical flue is not possible or desired,
an offset vertical flue can be used in conjunction with
a side horizontal flue extension piece and an
inline 135°/90° flue bend (Fig. 41).
Proceed with installation as detailed in section 5
up to 5.5.8., of the main Installation and Servicing
Instruction, 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 two wall fixing bracket securing
holes on the wall.
- Detach the template from the wall.
- Use a 10 mm dia. drill to make the 2 holes
securing fixing hanging bracket.
Insert plastic expansion plugs (Fig. 29).
- Screw in the two coach bolts.
- Position the flue extension and fix the
securing screw on the flue adaptor
appliance (Fig. 43) item 66, and ensure
that the gasket is correctly fitted.
Important:
Make sure that the flue
extension dia 60 mm duct is inserted fully
into the flue manifold, and the flue manifold
rubber seal is correctly fitted.
IMPORTANT NOTES : For greater flue length see
twin flue or concentric 80/125 flue instructions
