(504T model only):

■ Advanced ScreenLok

arrestor is designed to prevent ignition of flammable vapor outside of the
water heater.

■ Resettable Thermal Switch—Proven and reliable bimetallic switch

prevents burner and pilot operation in case of ongoing flammable vapor
burn inside of the combustion chamber or restricted air flow.

■ Pedestal Base—Rugged and durable base allows easy transport and

positioning, and provides corrosion resistant contact with floor.

■ Maintenance Free—Regular cleaning of air inlet openings or flame arrestor
