Installation
Exhaust-air Mode
Exhaust air should not be directed into a smoke or exhaust
flue that is currently used for other purposes, nor into a
shaft that is used for ventilating rooms in which stoves or
fireplaces are also located.
Exhaust air must be discharged in accordance with official
and statutory regulations only (e.g. national building
regulations).
Local regulations must be observed when discharging air
into smoke or exhaust flues that are not otherwise in use.
When the extractor hood is operated in exhaust-air mode
simultaneously with a different burner which also makes
use of the same chimney (such as gas, oil or coal-fired
heaters, continuous-flow heaters, hot-water boilers), care
must be taken to ensure that there is an adequate supply
of fresh air, which will be needed by the burner for
combustion.
Safe operation is possible provided that the underpressure in the room where the burner is installed does
not exceed 4 Pa (0.04 mbar).
This can be achieved if combustion air can flow through
non-lockable openings, e.g. in doors, windows and via the
air-intake/exhaust-air wall box or by other technical
measures, such as reciprocal interlocking, etc.
If the air intake is inadequate, there is a risk of carbon
monoxide poisoning from combustion gases which are
drawn back into the room.
An air-intake/exhaust-air wall box by itself is no guarantee
that the limiting value will not be exceeded.
NOTE: When assessing the overall requirement, the
combined ventilation system for the entire household
must be taken into consideration. This rule does not apply
to the use of cooking appliances, such as ranges and
ovens.
IMPORTANT SAFETY INSTRUCTIONS
• The blower must be attached at least 78¾'' (200 cm)
from the extractor hood.
• When attaching the outer wall blower, ensure that it is
accessible for maintenance and repairs.
• The plug-and-socket connections of the electric
cables must be located inside the building, according
to local codes.
• DO NOT reduce the 6'' (152 mm) diameter of the
ducting connected to the extractor hood.

Refer to the Installation Manual for important safety
instructions. Use gloves when installing blower unit.
1. The blower is attached to the hood using weld studs
provided on the mounting plate. Guide the motor
mounting plate over the studs.
2. Attach (4) nuts (included with hood) to the weld studs.
Tighten nuts to secure the blower to the hood.
3. Connect the blower’s plug connector to the connector
present inside the hood.
