Find your model on this page. Each one links to the owner's manual, installation manual, or brochure we found. The model name and serial number are on the fireplace's rating label, and some links go to archived copies or third-party sites rather than the manufacturer.
Often, yes. Kozy Heat is still family run in Lakefield, Minnesota, and its dealers order parts by model and serial number. Parts for the oldest models can be hard to find, so ask a dealer before you plan a repair.
Where we know it, each entry lists the model that replaced it. Many current Kozy Heat models carry on an older model's name or size, so check the current lineup too.
