State ProLine 74 Gal High-Recovery Atmospheric Gas Water Heater, 75,100 BTU

The State ProLine 100280137 (GS6-75-XRRS 400) is a 74-gallon high-recovery natural gas water heater with atmospheric venting. A 75,100 BTU burner gives a 125-gallon first hour rating, a solid choice for larger households with several fixtures in use.

Recovery reaches up to 81 GPH at a 90°F rise, rated storage is 71 gallons, and efficiency is 0.60 UEF with 80% thermal efficiency. The Green Choice burner meets Low NOx requirements. A push-button piezo lights the pilot and automatic safety controls manage the burner, so the heater needs no electrical power.

A 5 in. atmospheric vent connects to a properly sized chimney, which makes this a direct replacement for many natural draft heaters without reworking the venting. Top-mounted 1 in. NPT water connections come with heat-trap nipples. Corrosion and sediment are held back by a DynaClean self-cleaning dip tube, Blue Diamond glass lining and a stainless CoreGard anode.
