• Seal off any exhaust ventilation within about 15’ (5m) of
the solar attic fan to prevent the vent from re-breathing
the hot air exhausted by the fan. This is especially
important for ridge vents. Keep exhaust vents further
away open to allow passive ventilation when the fan
stops operating at night.
• Your solar attic fan requires at least 1 sq.ft. of Net Free
Area (NFA) for every 300CFM it is capable of. Install
additional vents if needed to match the capabilities of the
fan. Insufficient intake venting will cause the fan to pull
air from less desirable areas like conditioned air from the
home.
• Inspect the attic for possible leak points of conditioned air from the house into the attic. This could be can lights, holes, cracks, vents, etc.
Seal up any potential leak points according to local building code. Any conditioned air pulled into the attic from the house will diminish
the money saved from installing the fan by increasing the workload of the HVAC system.
