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 thermopile 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.
• *Not available on 60,000 BTU input models
(GCRX-50 and GCRX-55).
GREEN CHOICE
®
GAS BURNER
• Patented eco-friendly burner design reduces
NOx emissions by up to 33% and complies
with Low-NOx emission requirements of less
than 40 ng/J.
DYNACLEAN
™
DIFFUSER DIP TUBE
• Reduces 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 the pilot fast and easy with
one-hand push-button spark ignition.
HEAT TRAP NIPPLES
• Factory-installed for faster installation.
BLUE DIAMOND
®
GLASS COATING
• 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.
CODE COMPLIANCE
• Meets UBC, CEC and HUD National Codes.
• Meets the thermal efficiency and standby
loss requirements of the U. S. Department
of Energy and current edition of ASHRAE/
IES 90.1.
• Complies with the Federal Energy
Conservation Standards effective April 16,
2015, in accordance with the Energy Policy
and Conservation Act, (EPCA), as amended.
HIGH UNIFORM ENERGY FACTOR (UEF)
• Eco-Friendly non-CFC foam insulation,
external heat traps and specially designed
combustion chamber combine to produce
a high UEF for maximum savings on
operating costs.
