Bradford White's Defender Safety System~® Through the Wall Water Heaters Are Flammable Vapor Ignition Resistant

摘要

Beginning July 1, 2006, many Bradford White power-vented, through-the-wall water heaters will be manufactured with the Defender Safety System~®. This change will comply with new ANSI standards regarding Flammable Vapor Ignition resistance. The new TTW~® water heaters feature a different version of the highly successful Defender Safety System combustion and control system. This includes a new spark-to-pilot ignition system and an integrated immersion gas control valve with an LED indicator to assist in troubleshooting. An electronic sensor has also been included to prevent operation if flammable vapors are detected. The blower motor of the TTW~® unit has also been modified to offer better resistance to outside winds and to eliminate venting problems.
