The lawsuit was filed Monday in Cleveland federal court. It asks that it be made a class action on behalf of anyone with similar complaints against Heat Surge LLC, which is based in North Canton.
The lawsuit says Heat Surge fireplaces boasting "genuine Amish mantles" were inefficient. It says parts were made in China and didn't involve Amish workers in the U.S. as implied in advertising.
There was no immediate comment from the company about the lawsuit on Tuesday. The company says on its website it prides itself on the superior quality of its products.
The lawsuit seeks unspecified damages.
