or the appropriate standards of your country and MUST be
installed by a suitably qualified person.
B. The Fan should be provided with a local isolator switch capable of
disconnecting all poles, having a contact separation of at least
3mm.
C. Ensure that the mains supply (Voltage, Frequency, and Phase)
complies with the rating label.
D. The Fan should only be used in conjunction with the appropriate
Vent-Axia products.
E. The Fan should only be used in conjunction with fixed wiring.
F. When the Fan is used to remove air from a room containing a fuel-

both the fan and the fuel-burning appliance.
G. The Fan should not be used where it is liable to be subject to
direct water spray for prolonged periods of time.
H. Where ducted Fans are used to handle moisture-laden air, a
condensation trap should be fitted. Horizontal ducts should be
arranged to slope slightly downwards away from the Fan.
I. This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabilities, or

supervision or instruction concerning use of the appliance by a
person responsible for their safety.
J. Children should be supervised to ensure that they do not play with
the appliance.
K. Stationary appliances not fitted with means for disconnection from
the supply mains having a contact separation in all poles that

provide full disconnection under over voltage category III, the
instructions state that means for disconnection must be
incorporated in the fixed wiring in accordance with the wiring rules.
L. Ensure the grille is fully engaged onto the fan chassis using all
clips.
ACCESSORIES (not supplied)
WALL FITTING KIT
A range of 100mm wall kits are available for installing into most walls using telescopic liners
supplied.
WINDOW FITTING KIT
For use in single or sealed
double glazing and most
materials up to 40mm thick.
INSTALLATION
IMPORTANT: The fan should only be used in
conjunction with fixed wiring.
PANEL/CEILING MOUNTING
1. For panel/ceiling mounting the fan should be
installed into a closed duct protected by an
exterior air grille that must comply with the
standard requirements of your country to
prevent access to the fans impeller.
2. Cut a 105mm diameter hole for 100mm fans.
3. Push the two clips on the bottom of the fan
and pull the grille away from the chassis.
4. Using the built in spirit level bubble as an
aid. Mark the screw centres through the
holes in the fan back plate. Drill, plug and
screw into position.
5. After installation, ensure impeller rotates
freely and the shutters can open.
6. Replace the grille and ensure the clips
reactivate.
WALL MOUNTING
1. For wall mounting either cut a 115mm diameter hole for 100mm fans, through the wall and insert the
wall sleeve. Slope the sleeve slightly downwards away from the fan. Cut to length and cement both
ends into position flush with the wall faces.
2. Push the two clips on the bottom of the fan and pull the grille away from the chassis.
3. Using the built in spirit level bubble as an aid. Mark the screw centres through the holes in the fan
back plate. Drill, plug and screw into position. Fix exterior grille into position with the louvres
positioned downwards. (Note:- The grille must comply with the standard requirements of your
country to prevent access to the fans impeller. The wall kit used in this installation should provide a
minimum ducting length of 100mm from the fans back plate to the inside of the external grille).
4. After installation, ensure impeller rotates freely and the shutters can open.
5. Replace the grille and ensure the clips reactivate.
