The fan has a “boost” speed intended
to clear any minor exhaust obstructions. To
check its operation:
i.
Switch the fan on (9.1 to 9.3 above).
ii.
Go outside the building and place a hand
over the rectangular exhaust outlet of the
terminal. The fan should be heard to increase to “boost”
speed within approximately two seconds.
iii.
Remove the hand. The fan should revert to normal speed
after approximately three seconds.

The unit includes a blocked flue sensor system. To
check its operation:
i.
Switch the fan on (9.1 to 9.3 above).
ii.
Block off the rectangular exhaust outlet of the terminal.
The system should shut down and the indicator should
light within ten seconds.
iii.
After checking remove the flue blockage.
If the above tests are not satisfactory, refer to the servicing section of this
manual.
Note: At times of very windy weather or low voltage conditions the fan may switch between
boost and normal speeds. A click from the atmospheric pressure sensor may be heard as the
fan switches speeds.
