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).

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.
• ProLine
®
Master products have increased
anode protection with either longer, or
multiple anodes depending on model.

the protection for our industry-leading
commercial product line.
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 ENERGY FACTORS
• Eco-Friendly non-CFC foam insulation,
external heat traps and specially designed
combustion chamber combine to produce a
high Energy Factor for maximum savings on
operating costs.
