Counterflow is the trick: warm air is delivered low, so it does not just stratify at the ceiling. This is the intermittent-pilot version, which sparks the pilot electronically on each call for heat and burns nothing between cycles.\u003c\/p\u003e\u003cp\u003eIt vents conventionally through simple 4-inch Type B pipe rather than an expensive coaxial system, and its integral 275 CFM blower moves the heat without a separate accessory. Certified as a fan-type vented wall furnace, it is a serious supplemental heater for a room the central system underserves.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eThis furnace is part of the B-Vent Counterflow Wall Furnace family - use the selector above to compare sizes and pilot options.\u003c\/em\u003e\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e40,000 BTU\/hr counterflow heat:\u003c\/strong\u003e warm air delivered low at floor level, not stratified at the ceiling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntermittent Pilot ignition:\u003c\/strong\u003e electronic spark on each call - no gas burned between cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegral 275 CFM blower:\u003c\/strong\u003e circulation built in - no separate blower to buy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConventional B-vent:\u003c\/strong\u003e simple 4\" Type B pipe - no chimney or coaxial system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel-flexible:\u003c\/strong\u003e natural gas or propane; certified conversion kits available.\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\u003e40,000 BTU\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eCounterflow fan-type vented wall furnace\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVenting\u003c\/td\u003e\n\u003ctd\u003eB-Vent, Type B oval 4\" vent collar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuel\u003c\/td\u003e\n\u003ctd\u003eNatural Gas or Liquid Propane (certified conversion kits available)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAir Circulation\u003c\/td\u003e\n\u003ctd\u003eIntegral blower, 275 CFM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUnit (measured)\u003c\/td\u003e\n\u003ctd\u003e72-1\/2\" H x 14-1\/8\" W x 10-3\/8\" 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 (Fan Type 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 mounts in a standard 2x4 stud wall\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVenting:\u003c\/strong\u003e vents vertically through 4\" Type B pipe - plan the vent route to the roof before framing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas:\u003c\/strong\u003e 1\/2\" pipe inlet; order the correct fuel (40,000 BTU\/hr natural gas or propane)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl:\u003c\/strong\u003e pair with the \u003ca href=\"\/products\/empire-24-volt-wall-thermostat-direct-vent-wall-furnace-accessory\"\u003ewall thermostat\u003c\/a\u003e for automatic control\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eA permanently installed heating appliance, not a space heater.\u003c\/p\u003e","brand":"Empire Comfort Systems","offers":[{"title":"Natural Gas","offer_id":50213101469935,"sku":"FAW40IPXNAT","price":2849.0,"currency_code":"USD","in_stock":true},{"title":"Propane","offer_id":50213101502703,"sku":"FAW40IPXLP","price":2849.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/5633\/8415\/files\/FAW40SPPXNAT_348941e8-1f0e-406d-b22b-bca0173c8ce9.jpg?v=1784548098","url":"https:\/\/hearthdepot.com\/products\/empire-72-faw40ipx-intermittent-pilot-conventional-b-vent-counterflow-wall-furnace","provider":"Hearth Depot","version":"1.0","type":"link"}
