EN 15
• 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.
• 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 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.
