Gravity operation means no fan is required - warm air rises and circulates on its own - so at its quietest it runs in near silence, an advantage in bedrooms and hallways.\u003c\/p\u003e\u003cp\u003eIt vents conventionally through 4-inch Type B oval pipe and stands 66 inches tall in a slim 6-inch-deep cabinet. Add the optional blower package if you want to push the heat further, but the furnace needs no electricity to do its core job.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eThis furnace is part of the B-Vent Gravity Wall Furnace family - use the selector above to compare models.\u003c\/em\u003e\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-wall, two rooms at once:\u003c\/strong\u003e one 50,000 BTU\/hr furnace heats both sides of a shared partition wall.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGravity operation, near-silent:\u003c\/strong\u003e warm air circulates without a fan - and it heats with no electricity at all.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlim 6\" cabinet:\u003c\/strong\u003e tucks into a standard stud wall; 66\" tall, conventional 4\" B-vent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional heat boost:\u003c\/strong\u003e add the \u003ca href=\"\/products\/empire-automatic-blower-for-b-vent-gravity-wall-furnace\"\u003egravity-furnace blower\u003c\/a\u003e or a \u003ca href=\"\/products\/empire-remote-bulb-thermostat-for-b-vent-gravity-wall-furnace\"\u003eremote-bulb thermostat\u003c\/a\u003e.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel-flexible:\u003c\/strong\u003e natural gas or propane; certified as a vented wall furnace.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput\u003c\/td\u003e\n\u003ctd\u003e50,000 BTU\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eDual-wall gravity vented wall furnace (heats two rooms)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAir Circulation\u003c\/td\u003e\n\u003ctd\u003eGravity (no fan required); optional blower\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVenting\u003c\/td\u003e\n\u003ctd\u003eB-Vent, Type B oval 4\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuel\u003c\/td\u003e\n\u003ctd\u003eNatural Gas or Liquid Propane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUnit (measured)\u003c\/td\u003e\n\u003ctd\u003e66-1\/8\" H (71-7\/8\" with blower) x 16\" W x 6\" D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGas Inlet\u003c\/td\u003e\n\u003ctd\u003e1\/2\" pipe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertification\u003c\/td\u003e\n\u003ctd\u003eANSI Z21.86 \/ CSA 2.32 (Vented Wall Furnace)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e10-year limited parts (combustion chamber); 1-yr accessories\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eInstallation \u0026amp; Planning\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFraming:\u003c\/strong\u003e installs in the partition wall between the two rooms it heats\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVenting:\u003c\/strong\u003e vents up through 4\" Type B pipe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e gravity-driven - needs no power to run; the optional blower and thermostat are conveniences, not requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eA permanently installed heating appliance; confirm the shared-wall framing and vent route before installation.\u003c\/p\u003e","brand":"Empire Comfort Systems","offers":[{"title":"Propane","offer_id":50213107237103,"sku":"GWT50WLP","price":1889.0,"currency_code":"USD","in_stock":true},{"title":"Natural Gas","offer_id":50213107269871,"sku":"GWT50WNAT","price":1889.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/5633\/8415\/files\/empire_GWT50WLP-2_38b35267-6bae-408d-a6c0-1248767e7f32.jpg?v=1784548211","url":"https:\/\/hearthdepot.com\/products\/empire-66-gwt50w-b-vent-gravity-wall-furnace","provider":"Hearth Depot","version":"1.0","type":"link"}
