FMI Gas Fireplace Parts

Anyone who owns an FMI gas stove or fireplace system can get the right repair and maintenance parts from Mountain View Hearth Products. FMI Products (Fireplace Manufacturers, Inc.) was founded in 2009 and quickly became a leading manufacturer of high-end fireplaces and inserts. In 2012, Lennox Hearth Products merged with FMI and formed a new company called Innovative Hearth Products, or IHP. Since then, the FMI brand name has been phased out and new units will be manufactured under the Innovative Hearth Products brand.

Still, there are many FMI-branded fireplaces out there, and our selection of FMI Products replacement parts will let these owners maintain their excellent heating performance. We carry the full line of OEM replacement parts currently available for FMI gas stoves, gas fireplaces, and gas log sets. This includes parts for their vented and vent-free fireplaces.

Factory Replacement FMI Fireplace Parts

Whenever you need parts for a gas fireplace, you can get them at Mountain View Hearth Products. We have hundreds of parts in stock, including pilot assemblies, valves, thermostats, burner orifices, and wiring harnesses under the FMI and IHP brand names.

There are many ways to locate the parts you need. Click on a Part Type filter or use our search bar to enter part numbers, fireplace models, SKUs, and other information. Our support team is also available Monday through Friday to provide high-level customer service which includes troubleshooting and installation tips.
