Installation instructions
Height of island canopy
The island canopy is designed for 2440 mm high ceilings.
The chimney is telescopic and is designed for hood installations
between 600 to 750 mm above the cooking surface.
Ascertain the desired installation height of the island canopy.
Any installation above 750 mm will compromise the
extraction performance.
The air outlet from the motor requires 150 mm round ducting
which requires a 160 mm (min) diameter hole in the ceiling.
A = 600 min (electric cook top)
A = 650 min (gas cook top)
Ducting options
Recirculation
For recirculation, please purchase a recirculation kit (part no. RR1744). The recirculation kit is
required to channel the air out through the side-vents at the top of the flue.
Note: a ducting hole is not required to be cut in the ceiling if a recirculation kit is fitted.
Ducting
For ducted installation, it is recommended that you use 150 mm diameter, rigid or semi-rigid
ducting. This will require a 160 mm (min) round hole in the ceiling, which the decorative
chimney will cover. Care should be taken to align the canopy with the decorative chimney
allowing sufficient clearance to accommodate the ducting.
For optimum efficiency, use smooth-wall, solid galvanized or plastic ducting for reduced noise
and increased airflow. Flexible ducting should only be used as a last resort (ie in difficult
installations) and if used, ensure that it is pulled tight.
The smoother, straighter and shorter the ducting the quieter and more efficient the wall canopy
will perform.
All ducting must comply with local requirements and building codes.
Note: we recommend an Easy Fit by Fisher & Paykel or a UNIDUCT ducting system, products that
have been designed to expel air efficiently.
Preparing the island canopy for installation
Before drilling any holes check that the area behind the surface to be drilled is clear of any
electrical cables, pipes etc.
Fixing to a solid joist or 50 mm deep truss is recommended.
Whenever possible protect the cooktop with cardboard or the like to prevent damage
on installation.
