1.6 Technical specifications

At a distance of more than 2.5 metres the decibel count is less than 60 dB(A). This is
true only when the RSVG is mounted correctly. (For further details, see catalogue data.)
The standard version of the RSVG fan is designed to operate with a maximum flue gas
temperature of 250 °C.

1.7 Warranty

EXHAUSTO provides a two-year factory warranty on its chimney fans, valid from invoice
date.
EXHAUSTO fans must be installed by qualified technicians.
Once the fan has been installed, adjusted, and the customer has been trained in its use,
the installation instructions are to be handed over to the customer.
EXHAUSTO reserves the right to introduce changes to these guidelines without prior
notice.
The flow sensors must not be bent or moved, as this might affect their
performance.
Action
Use the installation switch to switch off the
fan. Wait until the fan stops rotating
Loosen the screws and open the top section
of the fan so that it hangs from its hinges and
the safety wire.
Remove any deposits on the centrifugal
impeller to the pressure sensors. Test the fail-
safe system and check whether it is damaged
in any way.
Check the base plate and top part of the fan
for soot deposits, and clean where necessary
with a scraper or brush.
When the fan is open it is also possible to
sweep the chimney. It is recommended that
the insert in the bottom section be removed
prior to sweeping. This allows better access to
the chimney.
Check that there is free access for fresh air to
the motor through the holes in the top section.
If, once reassembled, the fan vibrates
violently this might be due to an imbalance
caused by dirt on the centrifugal impeller. If
so, clean these parts again. Make sure that
any bias weights on the centrifugal impeller
are not removed.
