Operating procedure
MODENA Exhaust Hood has 2 (two) work methods as follows:
DUCTING / EXHAUST System:
• In this mode, the exhaust hood
operates by sucking the smoke/
cooking odor and then discharging it
out of the vent.
• A heat/fire-resistant ducting system is
required to discharge smoke/odor out
of the vent.
• To connect the exhaust hood with the discharge duct, use
"spigot/flange" is designed with a diameter of 100 or 125 mm.
Several things which require attention in installing the ducting system
exhaust hood:
1. Carbon filter must be removed because
the cooking odor will be sucked and
immediately discharged out of the room.
2. The suction force will be diminished if
the exhaust system is too long and there
are too many elbows.
3. Do not connect the exhaust system with a chimney or an air duct
or hot steam duct.
4. If the exhaust hood is to be installed in a multi-storied building or
an apartment, consult with the person in charge of the building /
apartment prior to installing the exhaust system.
5. Exhaust hood with ducting system should be used in an open-
air room with good air circulation.
RECIRCULATING system:
In this version, the exhaust hood sucks the smoke/cooking odor and
filters it through an aluminum filter and carbon filter. The filtered smoke
is then recirculated into the room. This system is used if the premise
renders it impossible to install a ducting system.
