AO Smith GCF-40 ProLine® XE 40 Gallons, 40 Input MBtu, High Efficiency Flue Damper, Non Condensing, Tall, Residential Natural Gas Water Heater, Atmospheric Vent, Indoor, 6 Year Warranty

PROLINE® XE FLUE DAMPER

AUTOMATIC FLUE DAMPER
• Increases efficiency as it automatically opens and closes to reduce heat loss in the standby mode.

ELECTRONIC GAS CONTROL
• Intelligent control logic provides enhanced operating parameters and tighter differentials for precise sensing and faster heating response to optimize performance.

DIAGNOSTICS
• The electronic gas control incorporates an LED status indicator that monitors system operation and service diagnostics

ELECTRONIC IGNITION
• Heater operates with an automatic pilot relight system that shuts off the pilot during stand-by modes to reduce gas consumption and eliminates nuisance pilot outage issues associated with standing pilot models.

POWER REQUIREMENTS
• Plugs into standard 110/120v outlet (10 foot power cord included).

DYNACLEAN™ DIFFUSER DIP TUBE
• Reduces lime and sediment buildup and maximizes hot water output. Made from long-lasting PEX cross-linked polymer.

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.

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.

ENHANCED-FLOW BRASS DRAIN VALVE
• Our residential water heaters have a solid brass, tamper resistant, enhancedflow, 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 straightthrough water flow but also a quick and positive shut off.

BLUE DIAMOND® GLASS COATING
• Provides superior corrosion resistance compared to industry standard glass lining.

CSA CERTIFIED AND ASME RATED T&P RELIEF VALVE 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.

DESIGN-CERTIFIED BY CSA INTERNATIONAL
• Certified at 300 psi test pressure and 150 psi working pressure. Listed according to ANSI Z21.10.1 - CSA 4.1 standards governing storage tank-type water heaters.
