Fit the horizontal powerflue wall terminal into the hole and fix it in place, making sure the installation is
sealed appropriately to prevent the ingress of water from outside the wall cladding.
Note: It is the responsibility of the installer to ensure the horizontal powerflue wall terminal is installed to
all relevant building codes to ensure weather tightness. This may necessitate the use of appropriate flashing
material where appropriate.
IMPORTANT:
Ensure that flashings do not restrict the air intake slot around the periphery of the
cowl.
How to Flash the Horizontal Powerflue
The following diagrams are excerpts from the Escea architect drawings and are available in full on our
website. These diagrams are recommendations, and your installation must comply with any local or
national building codes.

C4 Installing the Internal Vertical Powerflue (UVP)
Note: For information regarding an external install, go to section C5 on page
The Universal Vertical Powerflue (UVP) internal configuration is designed to
have the fan, mounted within the roof space of the house, and the vertical
Ø225mm diameter liner, containing a Ø100mm flexi, penetrate through
the roof. The UVP internal conversion kit comes with a 1200mm liner that is
specific to the internal installation and must always be used.
Note: The flue setup must comply with either section C1 on page 10 or C2 on
Use standard methods to flash the roof penetration. The installation must be
weatherproof and conform to all local council standards including powered flue
termination rules.
Mount the fan mount bracket (1) to the roof framing and strapping using
timber ensuring that the flue is rigid and vertical. Ensure that the mounting
timber does not obstruct access to the 3xM5 screw threads on the side of the
fan unit.
Aim to have the fan enclosure (2) mounted as high as possible, mainly to allow
sufficient fall for condensation drainage if the flexi-flue is to run horizontally.
Ensure there is sufficient space below fan enclosure (2) to have access to fit the
flexi-flue tubes (3) and allow flowing bends if required.
Note: The UVP-Internal and the flexi flue connections must be installed in
a location accessible for service or replacement; a service hatch or removable
flashing to allow access is required.
Note: When installing the unit onto a flue liner, ensure the length of flue liner above the roof is the minimum
required length.
ENSURE
the Ø25mm restriction plate is installed on the inlet.
