It heats room air through convection, making it well suited to well-insulated spaces where residual warmth is needed after the burner cycles off. The unit includes an integrated blower rated at 185 CFM, a thermostatic control knob with five settings, and an electronic push-button ignition. A built-in low-oxygen shutoff sensor monitors combustion air quality and shuts the heater down automatically if oxygen levels drop below safe thresholds. Wall and floor stand mounting kits are included in the box. Licensed HVAC technicians or qualified gas fitters are the appropriate trade for installation.\u003c\/p\u003e\n\u003cp\u003eThe HSSVFBF20NGBT is rated for supplemental heating in areas of approximately 450 to 500 square feet. It is designed for residential or light commercial vent-free applications where a dedicated flue is not available or practical. Because the unit operates on natural gas without requiring 120-volt power to produce heat, it continues to function as a heat source during electrical outages, though the blower will not operate without power. The heater can be mounted on a wall or set on the included floor stand feet, offering flexibility for different room layouts and code requirements. Vent-free products cannot be shipped to the state of California.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20,000 BTU natural gas output suitable for supplemental heating up to 500 square feet\u003c\/li\u003e\n  \u003cli\u003eIntegrated 185 CFM blower fan for improved air circulation during normal operation\u003c\/li\u003e\n  \u003cli\u003eThermostatic control with five settings modulates the flame as room temperature approaches the set point\u003c\/li\u003e\n  \u003cli\u003eElectronic push-button ignition with AA batteries included\u003c\/li\u003e\n  \u003cli\u003eBuilt-in low-oxygen shutoff sensor for automatic safety shutoff\u003c\/li\u003e\n  \u003cli\u003eWall mount bracket and base feet included for floor or wall installation\u003c\/li\u003e\n  \u003cli\u003eCSA and ANSI certified; 99.9% thermal efficiency rating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with natural gas supply systems. The HSSVFBF20NGBT is available in the natural gas configuration only; it is not rated for propane or mixed-gas service without manufacturer-specified conversion. Vent-free installation must comply with local building and mechanical codes governing unvented gas appliances.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed gas fitter or HVAC technician in accordance with the International Fuel Gas Code (IFGC) and applicable local codes. Shut off the gas supply at the service valve before making any connections. Minimum clearances must be maintained: 36 inches above the unit to the ceiling, 3 inches below the unit to the floor when using the base feet, and 10 inches to each side wall. For wall-mounted installations, the manufacturer recommends mounting at 36 inches from the floor for accessibility. Never install this heater in an enclosed space that does not meet the minimum volume requirements for unvented gas appliances as defined by the appliance listing and local mechanical codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Capacity\u003c\/strong\u003e: 20,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas (NG)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlame Type\u003c\/strong\u003e: Blue Flame\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIgnition Type\u003c\/strong\u003e: Electronic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Type\u003c\/strong\u003e: Thermostatic (5 settings)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlower CFM\u003c\/strong\u003e: 185 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVenting Type\u003c\/strong\u003e: Vent Free\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Connection Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManifold Pressure\u003c\/strong\u003e: 4.5 inches w.c.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Gas Pressure (Min.)\u003c\/strong\u003e: 9 inches w.c.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Gas Pressure (Max.)\u003c\/strong\u003e: 14 inches w.c.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Top to Ceiling\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Bottom to Floor\u003c\/strong\u003e: 3 inches (minimum)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance to Side Wall\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNet Weight\u003c\/strong\u003e: 27 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Type\u003c\/strong\u003e: Floor or Wall Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CSA, ANSI\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: ENERCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HSSVFBF20NGBT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ENERCO","offers":[{"title":"Default Title","offer_id":51283995918642,"sku":"HSSVFBF20NGBT","price":532.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279904.jpg?v=1781065453","url":"https:\/\/voomisupply.com\/products\/enerco-hssvfbf20ngbt-20000-btu-vent-free-blue-flame-heater","provider":"Voomi Supply","version":"1.0","type":"link"}
