S13 Servicing the Horizontal / Vertical Powerflue
Ensure the power to the Powerflue is o by disconnecting the power to the appliance inside. If the
appliance has been running, allow the Powerflue to cool before attempting to service it.
Servicing a horizontal Powerflue:
If the Powerflue needs servicing, the fan can be accessed from the outside of the installation for Hori-
zontal termination, and accessed from within the roof space for Vertical termination.
Undo the screws on the outside of the Powerflue box and separate the two parts, giving you access to
the fan inside.
Removing this plate gives complete access to the fan for servicing or replacement. Check that all the
seals are still intact. Check the fan electrical terminals, motor and impeller are not corroded. Ensure
there is no signs of leakage in or around the terminal.
When reassembling the powerflue, line up the round silicon grommets with the outlet tube of the fan
and push the cowl back into place. Ensure all seals are still in place and replace all of the screws to hold
the cowl in the correct position.
Servicing a Internal Vertical Powerflue:
If the vertical Powerflue needs servicing the fan can be
accessed without disturbing the final twin walled flue length or
roof terminal.
To gain access to the fan and electrical terminals remove the
eight screws that hold the base of the Powerflue to the lid,
making sure to support the base while removing the screws.
Note: When inspecting or working on the Powerflue take care
not to damage the two flexible flue pipes that connect to the
Powerflue base.
Once the base has been removed clean away any dust or de-
bris found and check that the fan electrical terminals, motor and impeller are not corroded. Also check
for signs of leakage in or around the Powerflue.
When reassembling the Powerflue support the base under the lid and replace the 8 securing screws.
After assembly check that the two flexible flue pipes are sealed and not damaged and that the twin
walled final flue length and roof terminal are still sealed.
Note : Take care not to trap any wires between the base and lid of the Powerflue when reassembling.
