S12 Servicing the Horizontal / Vertical Powerflue
Ensure the power to the powerflue is off 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:
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 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 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 Universal Vertical Powerflue:
If the UVP is internally installed remove the unit and replace the complete fan
unit.
If the UVP is externally installed the cowl/fan unit (shown right) is to be
completely replaced by removing it from the liner or flashing.
