Rated at 199,900 BTU\/h, it delivers a flow rate of 11.1 gallons per minute, making it suitable for high-demand whole-home hot water applications. The unit uses a direct vent configuration, drawing combustion air from outside and exhausting flue gases through a sealed venting system. A uniform energy factor of 0.98 reflects its condensing efficiency, which is among the highest available in the residential tankless category. Licensed plumbers and HVAC technicians typically handle installation.\u003c\/p\u003e\n\u003cp\u003eThis unit is intended for indoor residential installation where natural gas is the fuel source. The direct vent design makes it well-suited for tight spaces or interior mechanical rooms where combustion air cannot be drawn from the surrounding area. At 11.1 GPM, the GQ-C3261WX-FF US NG can support multiple simultaneous hot water draws in a single-family home or small multi-family setting. Its condensing operation requires a condensate drain connection during installation, which should be planned into the rough-in layout.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e199,900 BTU\/h input rating for high-demand residential hot water delivery\u003c\/li\u003e\n  \u003cli\u003e11.1 GPM flow rate supports multiple simultaneous fixtures\u003c\/li\u003e\n  \u003cli\u003eCondensing technology achieves 0.98 uniform energy factor\u003c\/li\u003e\n  \u003cli\u003eDirect vent system uses sealed combustion air intake and exhaust\u003c\/li\u003e\n  \u003cli\u003eNatural gas fuel type for compatibility with standard residential gas supply\u003c\/li\u003e\n  \u003cli\u003eIndoor-rated design for installation in conditioned or semi-conditioned spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style residential tankless water heater for natural gas indoor direct vent applications in the EZ Series Pro product line.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed plumber or qualified gas technician in accordance with local plumbing codes, the manufacturer instructions, and IFGC requirements. Shut off the gas supply and cold water inlet before beginning any work on the unit. The condensing design requires a proper condensate drain routed to an approved disposal point. Direct vent termination clearances must be verified per the manufacturer specification and local code before finalizing the flue run.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Input\u003c\/strong\u003e: 199,900 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 11.1 GPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniform Energy Factor\u003c\/strong\u003e: 0.98\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVenting Type\u003c\/strong\u003e: Direct Vent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Location\u003c\/strong\u003e: Indoor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondensing\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORITZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GQ-C3261WX-FF US NG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORITZ","offers":[{"title":"Default Title","offer_id":51524497375538,"sku":"EZ111DV-NEW","price":1782.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4b43f68d826894950dbd2009b1ed814.jpg?v=1785450080","url":"https:\/\/voomisupply.com\/products\/noritz-gq-c3261wx-ff-us-ng-tankless-water-heater-199900-btu","provider":"Voomi Supply","version":"1.0","type":"link"}
