Combustion-based water heaters generate exhaust gases as a byproduct of heating water. These gases, including carbon monoxide, are potentially hazardous. A properly functioning system safely removes these byproducts from the dwelling.
Effective exhaust removal is essential for occupant safety and maintaining air quality within a building. Historically, inadequate venting has led to serious health consequences. Current building codes mandate specific venting configurations to prevent the accumulation of dangerous emissions.
