It uses radiant or infrared heat transfer to warm objects and occupants directly rather than cycling air, delivering near-instant warmth with no flue or chimney connection required. The unit includes an electronic push-button ignition, a thermostatic control with five settings, and a built-in low-oxygen shutoff sensor. A blower rated at 185 CFM is included to distribute heat across the space. Installation hardware for both floor and wall mounting is included in the box. Licensed HVAC or gas technicians are the appropriate trade for final connection and commissioning.\u003c\/p\u003e\n\u003cp\u003eThe HSSVFRD20 is suited for uninsulated or semi-conditioned spaces such as garages, basements, workshops, and cabins up to approximately 500 square feet. It accepts either natural gas or liquid propane, making it adaptable to the available fuel supply at the job site. The unit runs without a dedicated electrical circuit for the burner itself, though the blower fan does require electricity. This makes it a practical option for locations where power reliability is a concern. The natural gas variant is available as model HSSVFRD20NGBT. Note that vent-free heaters cannot be shipped to California, and local codes and regulations must be consulted prior to installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20,000 BTU\/h infrared radiant output for spaces up to 500 square feet\u003c\/li\u003e\n  \u003cli\u003e99.9% AFUE rating for efficient fuel utilization\u003c\/li\u003e\n  \u003cli\u003eBuilt-in low-oxygen shutoff sensor for safe operation in occupied spaces\u003c\/li\u003e\n  \u003cli\u003eElectronic push-button ignition with AA batteries included\u003c\/li\u003e\n  \u003cli\u003eThermostatic control with five temperature settings\u003c\/li\u003e\n  \u003cli\u003e185 CFM blower included for improved heat distribution\u003c\/li\u003e\n  \u003cli\u003eWall mount bracket and base feet included for flexible positioning\u003c\/li\u003e\n  \u003cli\u003eCSA and ANSI certified construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe HSSVFRD20 is compatible with natural gas and liquid propane fuel supplies.

Shut off the gas supply completely before servicing or connecting the unit. Maintain required clearances: 36 inches above the heater to the ceiling, 3 inches from the floor when using base feet, and 10 inches to each side wall. When wall mounting, position the unit at a height of 36 inches from the floor. Keep all flammable materials, furniture, and textiles outside the required clearance envelope at all times.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Output\u003c\/strong\u003e: 20,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 99.9%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlower Airflow\u003c\/strong\u003e: 185 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIgnition Type\u003c\/strong\u003e: Electronic push-button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Type\u003c\/strong\u003e: Thermostatic, five settings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas or Liquid Propane\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVenting\u003c\/strong\u003e: Vent free\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlame Type\u003c\/strong\u003e: Infrared \/ Radiant\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 Minimum\u003c\/strong\u003e: 9 inches w.c.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Gas Pressure Maximum\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\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\u003eInstallation Type\u003c\/strong\u003e: Floor or Wall Mount\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\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: HSSVFRD20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ENERCO","offers":[{"title":"Default Title","offer_id":51283907477810,"sku":"HSSVFRD20","price":532.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279906.jpg?v=1781062964","url":"https:\/\/voomisupply.com\/products\/enerco-hssvfrd20-vent-free-infrared-heater-20000-btu-h","provider":"Voomi Supply","version":"1.0","type":"link"}
