exodraft RSV Chimney Extractor

exodraft RSV Chimney Extractor

UK – Product information

The exodraft RSV type chimney fan is supplied with location brackets, armoured cable, safety wire and a mineral wool mat, as well as packing to ensure the fan does not vibrate. (Two wing screws are also included, to be used where conditions allow).

Bad lighting habits can result in problems with soot, chimney fires, etc. which might damage the chimney fan. Please see our advice about lighting and maintaining a fire at www.exodraft.com or www.exodraft.co.uk.

Warning!

All installations must be carried out by competent personnel in accordance with national laws and regulations
Avoid chimney fires – ensure that the chimney has been swept before mounting the fan
The chimney fan should always be switched on when the fireplace or boiler is in use
Please always read the installation instructions for the exodraft control unit, before installation of the chimney fan.
If the exodraft fan system has been designed for solid fuel/multi fuel installations then please ensure the design meets the requirements of BS EN15287-1. If this can not be achieved, then a smoke alarm must be installed in the same room as the appliance.
exodraft would always recommend the use of a smoke alarm when a solid fuel open fire is installed
Avoid build up of soot and tar use only well seasoned wood (moisture content max 20 %)
Fans serving biomass boilers will inevitably receive a deposit from the appliance. Especially on biomass Boilers IT IS ESSENTIAL THAT A REGULAR INSPECTION AND CLEANING REGIME IS IMPLEMENTED, ESPECIALLY IN THE EARLY DAYS OF USAGE, TO ESTABLISH A PATTERN FOR TIMING OF REGULAR INSPECTIONS AND CLEANING.
Minimum distance to non-combustible material as per Fig. 4 A, or according to national legislation.

Installation instructions

The fan is designed to be fitted directly on top of brick or steel chimneys, as long as these are stable and level.

Before fitting onto a chimney

If …	then …
the fan is to be mounted onto a brick chimney	the chimney must have

location brackets – see below
the fan is to be mounted onto a steel chimney| a flange is required (supplied as an extra) – see below
the fan is a RSV315, 400 or 450| the impeller is secured with a safety bracket for transporta- tion.

**** Remove the transportation safety bracket located near the impeller and check that the impeller can turn freely.

Before fitting onto the brickwork of a chimney

Step| Action|
---|---|---
1| Measure the inside diameter of the chimney and cut the size of the hole in the mineral wool mat accordingly

Note, however, that there must always be a minimum of 20 mm of mat surface at any point around the circumference of the hole.

**** If a temperature sensor is to be installed with the chimney fan, cut a space for it on the mineral wool mat to make room for the sensor; this also ensures that the mat sits level on the chimney.

|

2| Fit the location brackets in the grooves on the underside of the bottom section and fasten using the nuts and bolts supplied.

Note that the bolts are to be inserted from beneath the brackets.

|

3| Adjust the distance between the location brackets to fit the inside diameter of the chimney, and then tighten the nuts. Note that there should be a 2-4 mm gap between the brackets and the chimney so as to avoid transmitting vibrations from the fan to the chimney.

**** A and B measurements: please refer to step 1.

**** The chimney fan can now be fitted into place. Place the mineral wool mat on top of the chimney, and place the fan on top.

|

Before fitting onto a steel chimney

Step| Action|
---|---|---
1| A flange (D) (supplied as extra) is used, fitted so that the spigot end sits inside the chimney (E).|
2| Place the mineral wool mat (B) on the flange (D) and cut a hole in the mineral wool mat, the hole being the same diameter as the flange hole.|
3| Cut the corners of the mineral wool mat, so there is room to fit the vibration dampers (C). If a temperature sensor is to be installed with the chimney fan, cut a space on the mineral wool mat to make room for the sensor; this also ensures that the mat sits level on the chimney|
4| Fit the flange to the chimney fan, with the use of the vibration dampers (C).|
5| The fan can now be fitted onto the chimney.|

Fitting the chimney fan onto the chimney

Step| Action|
---|---|---
1| Attach the safety wire to the chimney (1). Use the screw and rawl plug provided in the brickwork of the chimney or the self-cutting screw if working on a steel chimney. Then fit the wire through the hole in the bottom section and into the wire clamp.

**** Gently tighten the safety wire, and crimp (2) the wire clamp so that the fan is held safely in place when opened for servicing or cleaning purposes.

**** The isolation switch (supplied as extra) should be fitted onto the side of the chimney (3), so it is easily accessible when servicing the fan. The armoured cable with connecting cable should be mounted into the underside of the isolator and up into the switch through the coupling.

|

2| Prior to use check that:

The fan is closed and the fastening screws/wing screws tightened (4)
The safety wire is taut and the wire clamp crimped (5)
The coupling nut on the armoured cable is tightened (6)
The safety wire is securely attached to the chimney (7)
That the user is aware that the fan must always be switched on whenever the fireplace or boiler is in use
The transportation safety bracket has been removed (RSV315, -400 and -450).

Wiring

Fan and motor specifications are provided on the fan’s type plate. All the single-phased models are adjustable.
Wires are to be connected as per the wiring diagram. For further details, please see guidelines for the exodraft control units. All exodraft fans require extra safe-guards in accordance with power current regulations. Any lightning conductor connected to the fan must respect current applicable legislation.

Isolation switch:
In accordance with the provisions of the EU Machinery Directive a combustion- gas fan must always have an isolation switch fitted. The isolation switch must comply with national wiring standards.
Please refer to Machine Directive (2006/42/EF/-EEC/-EWG/-CEE) – Appendix 1item 1.6.3 “Separation of the sources of energy
The isolation switch must be ordered separately, as it is not part of the standard exodraft chimney fan delivery.

Service and cleaning

The motor in the RSV fan has special ball bearings that are sealed, life time lubricated, and maintenance-free. Any replacement of these bearings should be carried out by qualified professionals.
The fan should be checked and cleaned as required (at least once a year), depending on the fuel being used. Respect the following procedure:

Use the isolation switch to switch off the fan. Wait until the fan stops rotating
Loosen the screw and open the top section of the fan so that it hangs on its hinges and the safety wire
Using a scraper or brush, carefully clean the vane / centrifugal impeller
Check the path taken by the smoke through the top and bottom sections 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.
Check that there is free access for fresh air to the motor through the holes in the top section. Make sure that any weights on the centrifugal impeller are not removed.
Vibrations in the chimney fan can result in an imbalance due to a dirty axial vane / centrifugal wheel, and cleaning must be repeated. Make sure that any bias weights on the centrifugal impeller are not removed

Technical specifications

The sound level is below 68 dB at a distance greater than five metres away from the RSV fan when it is correctly fitted.
Further information is available in the catalogue.
The standard version of the RSV fan is designed to operate with a maximum flue gas temperature of 250 °C. At higher temperatures, though maximum 300 °C, the mineral wool mat should be replaced with adjusting screws (type RSD) or vibration dampers (type SVD.-RS) at the flange. See special guidelines for these parts.
The run capacitor is considered a wear part and will need to be replaced depending on usage.

Warranty

exodraft provides a six-year factory warranty on its flue gas fans, valid from invoice date.
exodraft fans must be installed by competent personnel.
exodraft reserves the right to introduce changes to these guidelines without prior notice.
