It uses a two-stage gas valve paired with an ECM variable-speed blower motor to deliver consistent heat output while reducing energy consumption. Airflow is adjustable from 1,200 to 2,000 CFM, making it suitable for a range of duct systems. The unit runs on 115 VAC, 60 Hz, single-phase power and accepts both natural gas and liquid propane. A zero-clearance downflow cabinet design allows installation in tight mechanical spaces. Licensed HVAC technicians install and commission this furnace.\u003c\/p\u003e\u003cp\u003eThis furnace is designed for downflow residential applications where the air handler is positioned above the living space and supply air is delivered downward. The two-stage operation reduces short-cycling and improves humidity control during mild weather. The ECM motor contributes to lower operating amp draw compared to PSC motors. At 5 nominal tons of airflow capacity, this unit is sized for larger residential or light-commercial heating systems. It is compatible with R-22 and R-410A air conditioning and heat pump systems when paired with a matching coil, and includes piston options with externally accessible bodies for TXV installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80% AFUE two-stage combustion for efficient fuel use across varying heating loads\u003c\/li\u003e\n\u003cli\u003eECM variable-speed blower motor with 1,200 to 2,000 CFM airflow range\u003c\/li\u003e\n\u003cli\u003eZero-clearance downflow cabinet measuring 34 inches tall, 21 inches wide, and 28 inches deep\u003c\/li\u003e\n\u003cli\u003eCompatible with natural gas and liquid propane fuel sources\u003c\/li\u003e\n\u003cli\u003eR-22 and R-410A refrigerant system compatible with piston or TXV coil options\u003c\/li\u003e\n\u003cli\u003eCased coil cabinets fully lined with 5\/8-inch foil-faced insulation for reduced cabinet heat loss\u003c\/li\u003e\n\u003cli\u003eIntertek lab tested at 1% or less cabinet air leakage for improved system efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with R-22 and R-410A air conditioning and heat pump systems.

Shut off gas supply and disconnect electrical power before servicing or replacing any components. Verify gas supply pressure, flue venting configuration, and duct static pressure are within the equipment design range before startup. Do not alter factory wiring or gas train components outside of approved field configurations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Capacity\u003c\/strong\u003e: 100,000 BTU\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Capacity\u003c\/strong\u003e: 80,000 BTU\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 80%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStaging\u003c\/strong\u003e: Two-Stage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: ECM Variable Speed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow Range\u003c\/strong\u003e: 1,200 to 2,000 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal CFM\u003c\/strong\u003e: 2,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Tons\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 115 VAC, 60 Hz, 1-Phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas \/ Liquid Propane\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Downflow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 34 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 28 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 120 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy Star\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RUUD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: U802VA100521ZSB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RUUD","offers":[{"title":"Default Title","offer_id":51284001489202,"sku":"U802VA100521ZSB","price":2931.48,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278902.jpg?v=1781065648","url":"https:\/\/voomisupply.com\/products\/ruud-u802va100521zsb-downflow-gas-furnace-100k-btu","provider":"Voomi Supply","version":"1.0","type":"link"}
