I inspected a Kohler steam unit for a sauna and the directions on the cover for the J-box says 105° wire terminations. Not enough detail for me to go on so I asked the contractor to use 105° wire for the final connection on the unit. Has anyone run into this before? The installation manual is silent on this and the nameplate says use #6 copper wire and install on a 70a. circuit breaker. I don't see a problem with the circuit since it is a heating unit but I guess the contractor is having trouble finding 105° #6 wire.

I have encountered a similar situation with some HID lighting fixtures.
While I can generally come into the fixture with THHN, and use the two-color Scotch wire nuts (which are 105 rated), without trouble .... when in doubt, I place another box a foot or so away from the fixture,and run a pigtail of fiberglass insulated wire. Such wire is available in appliance parts stores.

I've run into this also, usually with light fixtures. My electrical supplier carries type SA wire which is silicone insulated with a fiberglass jacket, rated 200C for dry locations. It is a little pricey, so I too use a j-box nearby to make the transition. Most wirenuts I've encountered are rated for the 105 degree temperature.
Few things are harder to put up with than the annoyance of a good example.
