All models are dual-listed for use in vent-free and vented multi-view applications and will deliver high heat output at 99% heat efficiency. The Superior Multi-Sided is described in the manufacturer's own price book as \"27\" MV Multi-Sided, VF System, Ceramic Fiber\", listed under the Gas Log Burner category of the Superior lineup, and covers Model Numbers FVFM27NR \/ FVFM27PR. A gas log burner is the working half of a vented or vent-free log set - it is the component that actually connects to the gas supply and produces the flame, sold separately from the decorative log casting that sits over it so the same burner can be paired with more than one log style.\u003c\/p\u003e\n\u003cp\u003eThis model burns Natural Gas or Propane at Natural Gas: 20,000-39,000 BTU\/hr · Propane: 20,000-39,000 BTU\/hr, and is built to ANSI Z223.1 \/ NFPA 54. A log burner installs into an existing masonry fireplace or an approved vented firebox, connected to the gas supply by a qualified installer, with the matching log casting placed over it according to the layout shown in the manual. Because burner and log set are sold as separate line items specifically so either can be replaced independently, confirm the burner size against the log set it will be paired with before ordering, since the two are matched by length. Electronic and variable models include a remote control as standard, while millivolt models are operated by a manual valve at the appliance itself - worth factoring in when deciding which ignition tier best suits how the fireplace will actually be used.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSuperior FVFM27NR - 27\" MV Multi-Sided, VF System, Ceramic Fiber\u003c\/li\u003e\n\u003cli\u003eSuperior FVFM27PR - 27\" MV Multi-Sided, VF System, Ceramic Fiber\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e27 Inch heater-rated appliance\u003c\/li\u003e\n\u003cli\u003e\n\u003c\/li\u003e\n\u003cli\u003eAvailable in Natural Gas and Propane\u003c\/li\u003e\n\u003cli\u003eNatural Gas: 20,000-39,000 BTU\/hr · Propane: 20,000-39,000 BTU\/hr\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eModel Series\u003c\/th\u003e\n\u003ctd\u003eMulti-Sided\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eCategory\u003c\/th\u003e\n\u003ctd\u003eVent-Free Fireplaces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eStyle\u003c\/th\u003e\n\u003ctd\u003eLog Sets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eDescription\u003c\/th\u003e\n\u003ctd\u003e27\" MV Multi-Sided, VF System, Ceramic Fiber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eFuel Type\u003c\/th\u003e\n\u003ctd\u003eNatural Gas or Propane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eInput Rating\u003c\/th\u003e\n\u003ctd\u003eNatural Gas: 20,000-39,000 BTU\/hr · Propane: 20,000-39,000 BTU\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eAgency Listing\u003c\/th\u003e\n\u003ctd\u003eBuilt to ANSI Z223.1 \/ NFPA 54\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eModel Numbers\u003c\/th\u003e\n\u003ctd\u003eFVFM27NR · FVFM27PR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eMaterial Numbers\u003c\/th\u003e\n\u003ctd\u003eF0073 · F0074\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Superior","offers":[{"title":"Natural Gas","offer_id":48312883675294,"sku":"FVFM27NR","price":1609.0,"currency_code":"USD","in_stock":true},{"title":"Propane","offer_id":48312883708062,"sku":"FVFM27PR","price":1609.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/9542\/9022\/files\/FVFM27NR.webp?v=1791177286","url":"https:\/\/usfireplaceshop.com\/products\/superior-multi-sided-27-built-in-gas-log-burner-with-millivolt-vent-free-system-and-ceramic-fiber","provider":"US Fireplace Shop","version":"1.0","type":"link"}
