I had a power vent on a tankless water heater. It's fan in the vent that drives the exhaust from combustion out the side of the house rather than letting it naturally rise through a traditional vent. It's wired into the burner so that it comes one when the burner ignites. Power vent doesn't come on, burner wont ignite. (I think)
