S10 Servicing the Horizontal/Universal Vertical Power Flue
Ensure the power to the power flue is o by disconnecting the power to the
appliance inside. If the appliance has been running, allow the power flue to
cool before attempting to service it.
Servicing a Horizontal Power Flue:
If the Power Flue needs servicing, the fan can be accessed from the outside
of the installation for horizontal termination and accessed from within the
roof space for vertical termination.
Undo the screws on the outside of the Power Flue 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 that the fan
electrical terminals, motor, and impeller are not corroded. Ensure there are
no signs of leakage in or around the terminal.
When reassembling the Power Flue, 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 Universal Vertical Power Flue:
If the UVP is internally installed remove the unit (2 in the right hand image)
and replace the complete fan unit.
If the UVP is externally installed the cowl/fan unit pictured below is to
be completely replaced by removing it from the liner or flashing.
