FAN DIMENSIONS
Before commencing work, study the tables shown in figures C1/ C2 to ensure fan will fit in position
proposed. NB: Allow a minimum of 54mm above fan casing for withdrawal of connector socket.
• Please note that for all Roof Fan installations a suitable sealing compound must be used to
seal the exterior roof cowl assembly to the glass/or roof plate, to ensure a weatherproof seal.
D1 THICKNESS OF GLASS
Fans can be fitted in most types of glass and fixing thickness up to 32mm, with the screws provided.
When fixing thickness exceeds 32mm, the unit should be secured with Extended Fixing Rods. If the
unit is to be installed in a location exposed to severe wind turbulence or in non-vertical panes, thicker
glass will be required – consult your nearest Vent-Axia Sales, Service and Distribution Centre.

INSTALLATION
F1 From the inside: Fit the spigot through the fixing hole, with the connector socket cut out at the
top. Ensure that the rubber seal is correctly located over the four lugs on the spigot.
F2i WINDOWFrom outside: Place the outdoor grille assembly with the louvres slanting downwards,
Vent-Axia logo at the top of the grille, over the projecting spigot.
F2ii ROOFFrom outside: Place the exterior roof cowl over the projecting spigot. Use a suitable sealing
compound between the cowl and the glass/or roof plate.
F3i/ ii Secure the outdoor grille or roof cowl, using the fixing screws supplied. Then tighten the
screws in turn to give an even pressure around the hole.
F4a/ b Refit the motor body housing assembly and turn clockwise until the locking catch is engaged.
Take care not to trap the mains supply cable or the speed controller socket cable (wired version
only).
F5 Release the Power Supply/Receiver Unit locking catch and lower until the catch engages in the
lower position, fix the controller socket into position (wired version only).
F6 Lift the black rubber gasket on the Power Supply/Receiver Unit and switch the three-position
switch to the required running option, then replace the gasket seal.
F7 If a speed controller is being used refer to the relevant Speed Controller Fitting and Wiring
instructions.
F8 Refit the housing ensuring that no internal wires are trapped between the housing and base.
F9 Engage the two side catches. Tighten the two side catch screws.
F10 Replace the indoor grille with the louvres slanting upwards
bottom of the grille, and secure with the retaining screw.

TYPICAL ROOF INSTALLATIONS USING VENT-AXIA ACCESSORIES
A
(A) ROOF LIGHT
All T-Series roof models are designed to fit directly
into horizontal and sloping glass including wired cast
and sealed double glazing up to 32mm thick. For
materials of greater thicknesses extended fixing rod
sets are available, allowing the unit to be fixed
through a spacing of up to 370mm.
Rod thread: 3.5mm
Maximum fixing thickness: 370mm
(B) PITCHED ROOF
All T-Series roof models may be installed in fixing
plates with zinc or lead weathering apron (provided by
others), fitted directly to a tiled or slated roof to
provide a water-tight installation. A suitable sealing
compound should be used between the
weathering apron and the exterior unit seal
The illustration shows a T-Series roof model fitted with
a direct mount spigot and flexible ducting.
C
(C) CORRUGATED ROOF
All T-Series roof models are suitable for fixing through
corrugated sloped and vertical cladding using a
suitable soaker flange. The soaker flange consists of
a replacement sheet with a flat section to carry the
unit.
A suitable sealing compound should be used between
the plate and the exterior unit seal.
(D) FLAT ROOF
All T-Series roof models may be installed through
solid roofs using a roof plate assembly and, if
required, an eggcrate grille or louvred grille in the
ceiling below. Alternatively, if ventilation is from a
suspended ceiling, single spigots and flexible ducting
may be used to connect the unit and extract grille.
Roof plate assemblies are manufactured in high
impact thermoplastic. A suitable sealing compound
should be used between the plate and exterior unit
seal.
