Residential Gas Water Heaters

POWER-VENT WATER HEATER

The ProMax® Power-Vent 40 and 50-gallon residential gas water heaters are equipped with
A. O. Smith’s pateneted C3 Technology
offering superior energy efficiency and operational cost savings. 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.

VERSATILE POWER-VENT DESIGN

40 and 50-gallon models vent using 2", 3" or 4" Schedule 40 PVC, CPVC or ABS pipe.

Canadian installations require ULC S636 approved PVC or CPVC pipe for venting.

System versatility allows combined horizontal and vertical vent runs up to 120 equivalent feet

with 3" pipe, up to 160 equivalent feet with 4" pipe on 40,000 BTU and 50,000 BTU models

All models supplied with termination elbow and screens. See page 2 for complete information

on vent distances and supplied elbows and screens for all models.

Corderite Combustion Containment (C3) design

meets American National Standards Institute standards
(ANSI Z21.10.1 or 10.3 - CSA 4.1 or 4.3) that deal with the accidental or
unintended ignition of flammable vapors, such as those emitted by gasoline.

Covered by four U.S. patents, C3 Technology gas water heaters
feature a sealed combustion chamber with air intake screen and
a fireproof Corderite flame arrestor built into the water heater base.

Power-Vent water heaters are also equipped with a flammable

gas control and hot surface ignitor if the presence of flammable vapors
is detected.

If flammable vapors
accidentally enter
the combustion
chamber, the
Corderite flame
arrestor is designed
so flames burn off
the top surface and
cannot escape down
through the arrestor.
