Rheostat Adjustment
Most vent configurations will require no adjustment to the rheostat. Vent configurations that fall
within the shaded area in the diagram below require the rheostat to be set to medium, medium-high, or
high (the rheostat ships in the medium position).
NOTE: The minimum vent length is 54" (this prevents the exhaust blower from over-heating).
The rheostat is adjusted by removing the nut holding the rheostat dial in place. Replace the nut and
cover after adjustment to insure the rheostat is not inadvertently adjusted.
NOTE: Make sure to re-install the rotating plate correctly. If you put it on upside-down it will not calibrate
correctly.
