5.5. Connecting the exhaust ducting

CAUTION!
IT IS COMPULSORY FOR EXHAUST DUCTS TO BE INSTALLED BY AN AUTHORISED INSTALLER
COMPANY, AND SUCH INSTALLATIONS MUST CONFORM TO THE EXISTING LAWS IN THE COUNTRY
OR AREA WHERE THE MACHINE IS USED.
DANGER!
THE SOOT AND FLUFF MUST BE PERIODICALLY CLEANED FROM THE INSIDE OF THE EXHAUST
DUCTING FROM THE MACHINE TO OUTSIDE. DO NOT FORGET THAT BOTH FLUFF AND SOOT ARE
HIGHLY COMBUSTIBLE MATERIALS. WE RECOMMEND CARRYING OUT THIS OPERATION AT LEAST
EVERY THREE MONTHS.
A FAULTY EXTRACTION SYSTEM CAN CAUSE SERIOUS RISKS TO THE HEALTH OF OPERATORS.
DANGER!
SPECIFIC WARNING FOR MACHINES WITH GAS HEATING.

THE EXHAUST DUCT MAY EXTRACT UNBURNT GAS.

SOME COMPONENTS FROM DRY CLEANING PROCESSES MAY DECOMPOSE INTO TOXIC
AND/OR CORROSIVE PRODUCTS IF THEY PASS THROUGH BURNER FLAMES.
FOR THIS REASON, THE MACHINE'S EXHAUST DUCT SHOULD ALWAYS LEAD DIRECTLY TO A
SECURE OUTSIDE LOCATION AND NEVER BE CONNECTED TO ANY OTHER DUCT OR CHIMNEY.
Specifications for the ducting
See the Connection details (Chapter 4) for the corresponding model for flow, diameter and position of
connection. Identified as EV.
It should be as short as possible, and the section specified in Details of Extraction Ducts must be maintained
throughout the whole ducting. A lengthier ducting will require a bigger section.
Must be fire-resistant, rigid, anti-corrosive with a smooth inside surface and these properties must remain
unaltered at a minimum of 150ºC (302ºF).
Watertight all around and thermally insulated up to a height from the floor of at least 2.7 metres (107 in).
If the extraction produces a significant noise, it is advisable to fit soundproofing.
Must have the minimum number of bends (to avoid losing contents the angle of the bends must not be more
than 45º).
Must always be conducted in an upwards direction. An upwards gradient of at least 3% and the shortest length
possible.
The outlet must be clear and separate (must never be joined to any other duct).
