8.1
Switch on power supply. The red indicator light at the left
side of the burner should be on.
8.2
Press and hold in the “on” switch. Within two seconds, the
Fan motor should start and the indicator light should go out.
8.3
Release the “on” switch. The fan should continue to run.
8.4
Press the “off” switch. The fan should stop and the
indicator light should come on.
8.5
The fan has a “boost” speed intended to clear any minor
exhaust obstructions. To check its operation:
i.
Switch the fan on (8.1 to 8.3 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.
8.6
The unit includes a blocked flue sensor system. To check its operation:
i.
Switch the fan on (8.1 to 8.3 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.
