FEATURES & BENEFITS
SELF-CLEANING DIP TUBES
Helps reduce lime and sediment buildup
and maximizes hot water output. Made
from the same long-lasting PEX cross-
linked polymer as our commercial dip tubes.
HEAT TRAP NIPPLES
Helps mitigate standby heat loss. Factory-
installed for faster installation.
T&P RELIEF VALVE
CSA Certified and ASME Rated.
COREGARD
™
ANODE ROD
Our anode rods have a stainless steel
core that extends the life of the anode
rod, allowing superior tank protection far
longer than standard anode rods.
SELF-POWERED ELECTRONIC
GAS VALVE
A. O. Smith gas water heaters are equipped
with a self-powered electronic gas valve
with intelligent control logic. The gas valve
has an internal microprocessor that provides
enhanced operating parameters and tighter differentials
for precise sensing and faster heating response to optimize
performance. The self-powered electronic gas valve uses a
thermopile to generate the power needed to operate the
electronic gas control without requiring an external power
source. It also incorporates an LED Status Indicator that
monitors system operation and service diagnostics.
BLUE DIAMOND
®
GLASS COATING
A patented commercial-grade formual
that provides superior corrosion
resistance compared to industry-standard
glass lining.
ENHANCED-FLOW BRASS DRAIN
VALVE
• Our residential water heaters have a
solid brass, tamper-resistant, enhanced-
flow, ball type drain valve.
• Uses a standard female hose fitting that
allows for fast and easy draining during
maintenance.
• Designed for easy operation, this valve
includes an integral screwdriver slot that
features a 1/4 turn (open/close) radius,
which not only permits full straight-
through water flow but also a quick and
positive shut off.
COMMERCIAL-GRADE ELECTRIC
ELEMENTS
ProLine
®
Master electric products are
outfitted with stainless steel upper and lower elements
that are modeled after those used in our industry-leading
commercial line. These elements are built to last with
thicker walls and a larger diameter sheath than the
elements in many competitive products.
