This is meaningfully different from new-construction fireplaces like Kozy Heat's Nordik series. Where new-construction units assume you're building a custom wall around the firebox, the Springfield 36 assumes you have an existing fireplace cavity (likely from a wood-burning fireplace or an older gas unit) and want to insert a modern, efficient direct-vent unit into it.\u003c\/p\u003e\n\u003cp\u003eThree design choices flow from that retrofit positioning:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered profile\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e— the Springfield 36 measures 35-3\/4\" wide at the front but tapers to 25-5\/16\" at the back, designed to fit standard masonry fireplace cavities that narrow toward the smoke chamber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModulating burner technology\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e— 18,000–35,000 BTU\/hr range with continuous adjustment, rather than the fixed single-stage burners typical of new-construction units.
