    How do I know correct setting (all the way open?) to allow fan to operate at max CFM? Would prefer not all the way open since unit is not as attractive when fully open.

    Thank you for your question regarding the CVG4. The larger the opening, the greater the air flow is for this unit. Please contact the Technical Services Department at 1-800-637-1453 for further assistance.
