• Do not obstruct the fan or exhaust grille to ensure optimum air passage.
• Ensure adequate air return into the room in compliance with existing regulations in
order to ensure proper device operation.
• If the environment in which the product is installed also houses a fuel-operating device
(water heater, methane stove etc., that is not a “sealed chamber” type), it is essential
to ensure adequate air intake, to ensure good combustion and proper equipment
operation.
• Install the product so that the impeller is not accessible from the air outlet side as
verified by contact with the Test Finger (test probe “B” of the norm EN61032) in
compliance with the current safety regulations.
• Make sure there is enough space around the unit for maintenance.
