the furnace and canvas both have their own separate warranties. the power lift should also.
go through your paperwork and you should be able to find contact info.
our canvas had a care/maintenance sheet in with the owner's manual and there's also a tag sewn inside one of the ends, with the manufacturer's name.
doesn't sound like your dealer is very helpful. even if you bought the extra 1 year warranty from FR, you're already past the 2 year mark, so FR sees it as an issue with the manufacturer of those things.
