{"product_id":"montigo-exemplar-r420-single-sided-fireplace-55-inch-frame","title":"Montigo Exemplar R420L Single-Sided Linear Fireplace, 53 9\/16\" Wide","description":"\u003cp\u003eThe Montigo Exemplar R420L starts with a fact worth noting: a 49 1\/4\" x 16 1\/8\" viewing area housed in a firebox that measures 53 9\/16\" wide and 38 1\/16\" tall. That's not a fireplace you walk past without noticing — it's a linear statement piece engineered for installations where the flame itself is the architecture.\u003c\/p\u003e\u003cp\u003eRunning on liquid propane at 55,000 BTU\/hr, the R420L uses a linear burner paired with glass accessories to produce the kind of clean, ribbon-style flame that defines contemporary hearth design. Heat output is substantial without being the whole story — the visual proportion of this unit is what earns its place in serious architectural projects.\u003c\/p\u003e\u003cp\u003eIgnition is handled by a Honeywell Hot Surface Ignition (HSI) system, one of the most dependable technologies in the industry. No pilot light to babysit, no manual lighting ritual — just a reliable, repeatable start every time. For a fireplace at this scale, that kind of dependability isn't a bonus feature, it's a baseline expectation Montigo has met.\u003c\/p\u003e\u003cp\u003eVenting is designated for a 5\"\/8\" diameter power vent system, and the R420L ships configured for top vent installation. Rear vent conversion is supported, giving your installer meaningful flexibility when working around structural constraints. That adaptability matters in custom builds where the fireplace location is decided long before the mechanical details are sorted.\u003c\/p\u003e\u003cp\u003eThe R420L is part of Montigo's R-Series Exemplar Single-Sided line, which spans multiple widths — the R320, R420, R520, R720, and R820 — making it easier to specify the right scale for a given space without compromising on the design language across a project. The frame width on this unit comes in at 60 11\/16\", and the firebox depth is 21 1\/8\", both worth confirming early in your rough-in planning.\u003c\/p\u003e\u003cp\u003eOne compatibility note worth keeping front of mind: the R420L's warranty requires the use of genuine Montigo parts. Third-party substitutions void coverage, so specify accordingly when working with your installation team.\u003c\/p\u003e\u003cp\u003eAt $10,779.00, the R420L is an investment in a fireplace that doesn't ask to be the center of attention — it simply is.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e53 9\/16\" firebox width with a 49 1\/4\" x 16 1\/8\" viewing area for a dramatic linear flame presentation\u003c\/li\u003e\n\u003cli\u003e55,000 BTU\/hr output on liquid propane (LP)\u003c\/li\u003e\n\u003cli\u003eHoneywell Hot Surface Ignition (HSI) for consistent, reliable starts\u003c\/li\u003e\n\u003cli\u003eLinear burner with glass accessories for a clean, contemporary flame profile\u003c\/li\u003e\n\u003cli\u003ePower vent system, 5\"\/8\" diameter, with top or rear vent capability\u003c\/li\u003e\n\u003cli\u003eShips configured for top vent; rear vent conversion supported\u003c\/li\u003e\n\u003cli\u003eFirebox depth: 21 1\/8\" | Frame width: 60 11\/16\"\u003c\/li\u003e\n\u003cli\u003ePart of the R-Series Exemplar Single-Sided line (R320 through R820) for scalable specification\u003c\/li\u003e\n\u003cli\u003eWarranty valid only with genuine Montigo parts — no third-party substitutions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ctable class=\"spec-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eR420L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuel Type\u003c\/td\u003e\n\u003ctd\u003eLiquid Propane (LP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBtu Rating\u003c\/td\u003e\n\u003ctd\u003e55,000 BTU\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIgnition System\u003c\/td\u003e\n\u003ctd\u003eHoneywell Hot Surface Ignition (HSI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBurner Type\u003c\/td\u003e\n\u003ctd\u003eLinear Burner with Glass Accessories\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVenting\u003c\/td\u003e\n\u003ctd\u003ePower Vent Designated, 5\"\/8\" dia., top or rear vent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFirebox Width\u003c\/td\u003e\n\u003ctd\u003e53 9\/16\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFirebox Height\u003c\/td\u003e\n\u003ctd\u003e38 1\/16\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFirebox Depth\u003c\/td\u003e\n\u003ctd\u003e21 1\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrame Width\u003c\/td\u003e\n\u003ctd\u003e60 11\/16\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eViewing Area\u003c\/td\u003e\n\u003ctd\u003e49 1\/4\" x 16 1\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Montigo","offers":[{"title":"Propane","offer_id":45054151983312,"sku":"R420L","price":10779.0,"currency_code":"USD","in_stock":true},{"title":"Natural Gas","offer_id":45054152016080,"sku":"R420N","price":10779.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0506\/3999\/5088\/files\/R420_01.jpg?v=1782714716","url":"https:\/\/www.shopsandersgas.com\/products\/montigo-exemplar-r420-single-sided-fireplace-55-inch-frame","provider":"Shop Sanders Gas","version":"1.0","type":"link"}
