Topics:

• Ventilation system blows air back into room instead of pulling air out
• Blower installed incorrectly
• Vent hood or downdraft pushing air back into room

Cause:

• Blower installed incorrectly
• Duct run is excessive
• Too many elbows or transitions in duct run

Answer:

If a Wolf ventilation system is pushing air back into the room, verify that the blower is installed correctly.

• Inline blowers installed backwards will push the air back into the room.
• Limit the number of elbows in the duct run when possible.
• Elbows placed too close together may cause the air to back up into the room.
