The manufacturer does not warrant any roof damage caused by excessive vacuum or internal
pressure from fans or other air moving systems. Adequate ventilation and/or “makeup air”
devices should be provided for all powered air handling systems. The manufacturer does not
recommend the use of downward flow systems (suction). Severe roof damage can result from
any blockage of air passages. Running fans during high humidity/cold weather conditions can
cause air exhaust or intake ports to freeze.
