It's a strong fit for upgrading an old wood-burning fireplace or installing as a clean, gas-free built-in feature in a new wall, and the wider viewing area gives the multi-dimensional flame effect noticeably more presence than the smaller Redstone sizes offer, without requiring a proportionally larger installation budget or extended construction timeline for the homeowner.\u003c\/p\u003e \u003cp\u003eThe heater alone covers up to 400 square feet at 5,000 BTU, making it practical as a genuine secondary heat source for living rooms, dens, and apartments rather than a purely decorative unit that only produces visual warmth. Flame speed, ember bed color, and downlighting are each independently adjustable through the included remote or the free Modern Flames app, and the fireplace ships with a driftwood log set and acrylic crystal media already arranged for a layered, realistic ember bed. Because it installs as either a retrofit insert or a new-construction built-in, it fits both renovation projects and fresh builds without requiring a gas line, chimney, or venting of any kind. It's CSA certified and backed by a 5-year manufacturer's warranty, reflecting a fireplace meant for daily use rather than occasional ambiance.\u003c\/p\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eHybrid-FX™ Flame Technology\u003c\/strong\u003e – multi-dimensional flame depth and motion\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMulti-Color Flame, Ember Bed \u0026amp; Downlighting\u003c\/strong\u003e – independent RGB control for each zone\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBuilt-In or Insert Installation\u003c\/strong\u003e – retrofit or new construction\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e5,000 BTU Heater\u003c\/strong\u003e – adjustable thermostat and timer, up to 400 sq ft\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eRemote \u0026amp; App Control\u003c\/strong\u003e – handheld remote plus iOS\/Android app\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eNo Venting Required\u003c\/strong\u003e – fully electric, no gas or chimney\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eSpecifications\u003c\/h3\u003e \u003ctable border=\"1\" cellpadding=\"6\" cellspacing=\"0\"\u003e \u003ctbody\u003e \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRS-4229\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRedstone\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFlame Technology\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHybrid-FX™\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFireplace Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e39-3\/4\" W x 27\" H x 9-7\/8\" D\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eViewing Area\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e38-1\/2\" W x 24\" H\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBuilt-In\/Clean Face\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVolts \/ Watts\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e120V \/ 1500W\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBTU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5,000\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCertifications\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCSA Certified\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWarranty\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5-Year Manufacturer's Warranty\u003c\/td\u003e\n\u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ch3\u003eDocuments \u0026amp; Files\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0703\/9542\/9022\/files\/Redstone-Series-COMBO-2022-web_1.pdf?v=1753589255\" rel=\"noopener\" target=\"_blank\"\u003eRedstone Brochure\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0703\/9542\/9022\/files\/Redstone-USA-owners-manual.pdf?v=1753555538\" rel=\"noopener\" target=\"_blank\"\u003eOwner's Manual\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0703\/9542\/9022\/files\/MF-RedStone-Extra-Wide-Trim-Instructions-9.2020-copy.pdf?v=1753555527\" rel=\"noopener\" target=\"_blank\"\u003eTrim Installation Instructions\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0703\/9542\/9022\/files\/Modern_Flames_Warranty_Policy.pdf?v=1753555499\" rel=\"noopener\" target=\"_blank\"\u003eWarranty Policy\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"Modern Flames","offers":[{"title":"Default Title","offer_id":50202689273994,"sku":"RS-4229","price":1699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6029\/4026\/files\/Modern_Flames_RedStone_5_95565900-4308-463d-b353-69d4a52a0eab.webp?v=1789479708","url":"https:\/\/modernflamesshop.com\/products\/modern-flames-redstone-42-built-in-insert-electric-fireplace","provider":"Modern Flames Shop","version":"1.0","type":"link"}
