Description
RSV chimney fans are used with heating appliances and provide a
controllable negative pressure along the full length of the flue and
chimney. The fans guarantee optimum chimney draught irrespective of the
placing, dimensions or height of the chimney which is beneficial to new
or existing installations.
RSV chimney fans are normally installed on top of the chimney where the
vertical discharge column prevents a plume of gas flowing down the
outside of the chimney and thereby complies with the Clean Air Act. RSV fans can also be wall mounted. |

The fans can be
used with appliances burning oil or solid fuel. For solid fuel, the
fans are supplied with a stainless steel axial vane, which is easy to
clean. For oil the fans are supplied with a backward curved
impeller, which gives high fan efficiency.
The chimney fans offer capacities which will cover any heating
appliance from small domestic fireplaces to multiple boiler
installations with a heat output up to 2MW using a single chimney fan.
Construction
RSV chimney fans are specially made to withstand flue gas temperatures up
to 250°C continuously.
RSV chimney fans are constructed of corrosion resistant cast aluminium
and are supplied in grey, painted finish.
The fans are hinged for easy access for service and maintenance on solid
fuel appliances. The
fans have a mesh safety guard covering the vertical discharge.
The fans are fitted with an entirely closed, asynchronous motor with
ball bearings sealed for life. The motor is specially constructed to
provide reliable operation at a high temperature. It is made to
international classifications IP54 (degree of protection) and F
(insulation). The motor is located inside the motor housing and thus
separated from the flue gases.
The electrical connection is provided by a heat resistant silicone cable
and is also protected by armoured cable. The motors (1 x 230V) are
infinitely adjustable.
The fans are supplied with a 30 days money back guarantee, and a 2 year
warranty.
Installation
The fan is located on the top of the chimney. For the fans RSV9-RSV16
the glass fibre mat must be cut accordingly to the inside diameter of
the flue. The fans RSV160-RSV400 are supplied with a pre-cut glass fibre
mat corresponding to the chimney fan size.
Locate the location brackets in the grooves on the underside of the fan
base plate. The glass fibre mat is placed on top of the chimney with the
aluminium foil facing upwards. Locate the fan on top of it.
If installed on a metal chimney the fan should be installed with flange
type FRSV and if needed also with anti-vibration bolts instead of
location brackets. If the anti-vibration bolts are used, the corners of
the glass fibre mat must also be cut off.
Maintenance
Service and cleaning of the fan should be as required depending on the
fuel used (at least once a year on solid fuel). In open position the hinged chimney
fan provides easy access for service and maintenance on solid fuel.
