What was the brand name of the product to use.  They have changed the emissions requirements in Illinois to restrict CO emissions to 40% of levels used 2 years ago.  I need the product!  Thanks!  : )

If anyone ever has TGP that runs at 220 degrees or more, simply remove your thermostat!  All will be fine until emissions test time!  : ) THe problem was that your thermostat was not opening.  I know from experience with a 10-year old 160-degree stat!
