DIRECT VENT DESIGN

• One-pipe, dual-channel closed system

draws all make-up air from outside the

home, eliminating problems caused by

insufﬁcient indoor ventilation and is

FVIR compliant. Horizontal air intake and

venting on all models up to 80 inches

from outside wall with no electrical

power needed.

INTELLIGENT CONTROL LOGIC

• The internal microprocessor provides

enhanced operating parameters and

tighter differentials for precise sensing

and faster heating response to optimize

performance.

• Uses a themopile to generate the power

needed to operate the electronic gas

control without requiring an external

power source.

• The electronic gas control incorporates

an LED status indicator that monitors

system operation and service

diagnostics.

GREEN CHOICE

GAS BURNER

• Patented eco-friendly design reduces

NOx emissions up to 33% and complies

with low emissions of less than 40 ng/J.

DYNACLEAN™ DIFFUSER DIP TUBE

• Helps reduce lime and sediment buildup

and maximizes hot water output. Made

from long-lasting PEX cross-linked

polymer.

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.

PUSH BUTTON PIEZO IGNITOR

• Makes lighting pilot fast and easy with

one hand push button spark ignition.

HEAT TRAP NIPPLES

• Factory-installed for faster installation

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 ¼ turn (open/close) radius,

which not only permits full straight-

through water ﬂow but also a quick and

positive shut off.
