Residential Gas Water Heaters

HIGH EFFICIENCY RESIDENTIAL MODELS

FEATURES AUTOMATIC FLUE DAMPER

■ Increases efﬁciency as it automatically opens and closes to reduce heat loss in

the standby mode.

ENERGY STAR® QUALIFIED

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

■ Helps reduce lime and sediment buildup, maximize hot water output. Made

from long-lasting PEX cross-linked polymer.

COREGARD™ ANODE ROD

■ An A. O. Smith exclusive. Anode has stainless steel core, protects tank against

corrosion longer than ordinary steel anodes.

DURABLE BRASS TAMPER-RESISTANT DRAIN VALVE

BLUE DIAMOND

■ Provides superior corrosion resistance to industry-standard glass lining.

GLASS COATING

CSA CERTIFIED AND ASME RATED T&P RELIEF VALVE

■ Top-mounted T&P Relief Valve available as option on all models.

CODE COMPLIANCE

■ Meets and exceeds NRCan energy efﬁciency requirements

■ Models are complient to the B.C. Energy Efﬁciency Act Standards

DESIGN-CERTIFIED BY CSA INTERNATIONAL

■ According to ANSI Z21.10.1 - 4.1 CSA Standards governing

storage-type water heaters.
