ProMax Residential Gas Water Heater

The ProMax Power-Vent 40 and 50-gallon residential gas water heaters are equipped with A. O. Smith's patented C3 Technology design, and meet Phase II of the ANSI Z21.10.1 standards for flammable vapor ignition resistance. In addition A. O. Smith has engineered other enhancements into its power-vent design, for easier installation and maximum venting flexibility. A power-vent water heater provides an alternative to conventional vertical-vent models, which require the use of a metal vent. They provide a solution to potential venting problems in replacement applications and offer versatile options for placement of gas water heaters in residential new construction.
