Mount the suction and exhaust pipe to the motor unit by means of a hose clamp. Connect the plug of the cable co-
ming from the ceiling unit to the plug on the motor unit.
INSTALL THE EXHAUST DUCT
The motor outlet has a diameter of 150 mm. It is recommended to connect an exhaust duct with a diameter of 150 mm to
this. A reducer is supplied with the hood. Only mount the reducer when using an exhaust duct with a diameter of 125 mm.
For optimum performance of the hood it is important to pay attention to the following points.
Circular ducts:
• Use smooth, non-flammable pipes with an internal diameter that is equal to the external diameter of the connection
nozzle of the hood. Maximally extend flexible ducts and cut them to size.
• Do not reduce the exhaust diameter. This will lower the capacity and raise the noise level.
• When connecting to a short exhaust duct, it may be required to mount a non-return valve in the duct to avoid wind
blowing in.
• Use a hose clamp or aluminum tape for airtight connections.
• In case of an exhaust pipe through the wall, use a wall vent.
Flat duct:
• Use flat duct with rounded corners and with air deflectors. Available at Novy.
General information:
• Make the duct as short as possible and with as few as possible bends to the outside.
• Avoid square bends. Use rounded bends for proper air conduction.
• In case of an exhaust pipe through the outside wall passing a cavity wall, make sure that the exhaust duct fully bridges
the cavity and slightly declines to the outside.
• In case of an exhaust pipe through the roof, use a double-walled roof passage with sufficient width.
• Never connect to a flue duct.
• Make sure that sufficient air is supplied. Fresh air can be supplied by slightly opening a window or an outside door or
by installing an inlet grate.
ACCESSORIES
Adapter for connecting flat ducts
The motor is mounted remotely by using the adapter and you are able to connect a flat duct directly to the ceiling unit.
The advantage is the low build-in height (article number 6830052).
Recirculation
If you choose for recirculation, Novy offers the exhaust box in different sizes, including type 830400 (stainless steel ex-
haust grid), type 831400 (white exhaust grid), type 7900400 (stainless steel exhaust grid) or type 7910400 (stainless steel
exhaust grid).
Extension cable
When mounting the motor unit remotely, it may be desirable to mount a longer cable between the ceiling unit and the
motor. The extension cable is connected to the existing cable. The extension cable has a length of 5 m.
