{"product_id":"empire-keystone-deluxe-b-vent-zero-clearance-gas-fireplace-36","title":"Empire Keystone Deluxe B-Vent Zero Clearance Gas Fireplace, 36\"","description":"\u003cp\u003eThe Empire Keystone Deluxe B-Vent Fireplace delivers 25,000 BTU\/hr of natural gas heat through a clean, flush-face design that integrates neatly into a finished surround without demanding additional clearance from combustibles. At 36 inches wide and 83 pounds, it's a substantial unit built to anchor a room — not just accessorize it.\u003c\/p\u003e\u003cp\u003eMillivolt ignition means this fireplace operates entirely without a dedicated electrical connection. That's not a minor detail: in a power outage, your fire keeps burning. The self-contained ignition system is simple, proven, and doesn't ask anything of your home's wiring.\u003c\/p\u003e\u003cp\u003eVenting runs through a 6-inch diameter B-vent, which draws combustion air from the room and exhausts vertically — a straightforward approach that's been the standard for interior gas fireplaces for decades, and remains the right choice for many installations.\u003c\/p\u003e\u003cp\u003eThe Keystone Deluxe ships with a log set that is specifically engineered for its burner configuration. This isn't a limitation so much as a deliberate design decision: the pairing ensures combustion performance, flame appearance, and safety all work together as intended. Swapping in alternate media isn't supported, and for good reason.\u003c\/p\u003e\u003cp\u003eRunning natural gas out of the box, the unit is compatible with a natural gas to propane conversion kit if your home runs on LP — making it adaptable without requiring a separate SKU. On louvered models, the optional FBB4 automatic blower with variable speed control is a compatible upgrade worth considering if active heat circulation matters to your space.\u003c\/p\u003e\u003cp\u003eThis is a zero-clearance fireplace, which means installation flexibility isn't sacrificed to accommodate a thick firebox wall. Frame it into new construction or a remodel without building out a massive chase around it.\u003c\/p\u003e\u003cp\u003eAt $1,969, the Keystone Deluxe sits in a range where build quality, a reputable manufacturer, and a no-electricity-required ignition system make it a considered purchase — not an impulse buy, but the kind of fireplace that earns its place in a room for years.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e25,000 BTU\/hr maximum input — natural gas\u003c\/li\u003e\n\u003cli\u003e36-inch wide, flush-face zero clearance design\u003c\/li\u003e\n\u003cli\u003eMillivolt ignition: operates independently of household electricity\u003c\/li\u003e\n\u003cli\u003e6\" diameter B-vent for vertical venting\u003c\/li\u003e\n\u003cli\u003eIncluded log set is purpose-matched to the burner — no alternate media supported\u003c\/li\u003e\n\u003cli\u003eConvertible to propane with a natural gas to propane conversion kit (sold separately)\u003c\/li\u003e\n\u003cli\u003eCompatible with optional FBB4 automatic blower with variable speed control (louvered models)\u003c\/li\u003e\n\u003cli\u003eZero clearance construction for flexible installation in new builds or remodels\u003c\/li\u003e\n\u003cli\u003e83 lbs — substantial, well-built construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ctable class=\"spec-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Btu\/Hr (Maximum)\u003c\/td\u003e\n\u003ctd\u003e25,000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eB-Vent Size\u003c\/td\u003e\n\u003ctd\u003e6\" Diameter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuel Type\u003c\/td\u003e\n\u003ctd\u003eNatural Gas\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFace Type\u003c\/td\u003e\n\u003ctd\u003eFlush Face\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIgnition Type\u003c\/td\u003e\n\u003ctd\u003eMillivolt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eB-Vent Zero Clearance Gas Fireplace\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e36-inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eItem Weight Lbs\u003c\/td\u003e\n\u003ctd\u003e83.00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Empire Comfort Systems","offers":[{"title":"Default Title","offer_id":45054072357072,"sku":"BVD36FP30FN","price":1969.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0506\/3999\/5088\/files\/BVD36FP30F_01.jpg?v=1782711544","url":"https:\/\/www.shopsandersgas.com\/products\/empire-keystone-deluxe-b-vent-zero-clearance-gas-fireplace-36","provider":"Shop Sanders Gas","version":"1.0","type":"link"}
