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).

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.
