Ao Smith 100266135 Concentric Pipe Vent Kit 39 Inches

Product Description

The AO SMITH 100266135 is a straight concentric pipe vent kit designed for direct-vent water heater installations. Measuring 39 inches in length, this vent kit provides the concentric pipe configuration that routes combustion exhaust and intake air through a single termination point. Licensed plumbers and HVAC technicians use this kit during new installations or vent system replacements on compatible direct-vent water heater equipment. The straight design simplifies routing in applications where a direct, unobstructed run is available from the appliance to the exterior termination.

This vent kit is suited for residential and light commercial direct-vent water heater applications where a 39-inch straight run is required. Concentric venting systems are common in high-efficiency water heater installations, allowing both exhaust and combustion air to pass through a single wall or roof penetration. This kit is intended for use in applications where the water heater manufacturer specifies a concentric vent configuration.
