Traditional methods of combustion venting are sometimes not an option: perhaps the old chimney needs expensive upgrades, or there is no chimney at all! Enter Direct Vent, sophisticated heating technology from NTI. Located through the basement wall (or wherever the boiler is located), the Direct Vent efficiently draws outside air through the vent terminal where it is pre-heated and used for the combustion process.
