It delivers up to 8.4 gallons per minute (GPM) of continuous hot water and runs on natural gas with a direct vent configuration for indoor installation. The unit operates on 120 volts and features a stainless steel condensing heat exchanger built for long-term durability. Lead-free construction meets current potable water standards. Licensed plumbers install this unit in residential and light commercial applications where on-demand hot water and reduced energy consumption are both priorities.\u003c\/p\u003e\u003cp\u003eThe RUTGH-84DVLN-2 is designed for indoor installation using direct vent piping in 2-inch, 3-inch, or 4-inch diameter configurations. It suits residential builds and retrofits where storage-tank water heaters are being replaced with on-demand systems. A minimum flow activation rate of 0.40 GPM and a minimum flow rate of 0.26 GPM make it functional in low-demand situations. The unit is also recirculation pump kit-ready, supporting faster hot water delivery at the tap. Hot Start Programming keeps the unit in a ready-fire state to reduce cold water bursts during back-to-back draw cycles, a common issue in multi-fixture residential settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e180,000 BTU\/h input rating with 0.93 UEF for condensing-class efficiency\u003c\/li\u003e\n\u003cli\u003e8.4 GPM maximum flow rate for continuous hot water delivery\u003c\/li\u003e\n\u003cli\u003eStainless steel condensing heat exchanger for corrosion resistance and longevity\u003c\/li\u003e\n\u003cli\u003eDirect vent compatible with 2-inch, 3-inch, or 4-inch vent pipe\u003c\/li\u003e\n\u003cli\u003eRecirculation pump kit-ready for reduced wait times and water savings\u003c\/li\u003e\n\u003cli\u003eWater Savings Setting and Hot Start Programming reduce water waste and cold-water interruptions\u003c\/li\u003e\n\u003cli\u003eENERGY STAR rated; meets AIA, AHRI, CSA, and CUPC standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe RUTGH-84DVLN-2 is part of the RUUD RUTGH series of condensing tankless gas water heaters.
