Light Duty Power Vent Propane Models

Light Duty Power Vent (TTW®) (Through-the-Wall) units are perfect for applications where installation flexibility is as important as meeting hot water demands. Power vented for positive exhaust, these units can be vented horizontally and vertically up to 180 feet. These extremely long vent lengths solve difficult ventilation challenges. Light Duty Power Vent models are also available in Ultra Low NOx versions.
