Excel 2100 Chimney System

Excel 2100 Chimney System

EXCEL Features

  • EXCEL is tested and listed to the ULC S-629 chimney standard. The ULC standard is generally considered the toughest residential chimney standard in the world. The USA standard requires the chimney to withstand three 10-minute 2100°F chimney fires. The Canadian standard requires the chimney to withstand three 30-minute chimney fires, three times longer than the USA.
  • EXCEL is the only 1 inch wall insulated chimney to pass the ULC standard.
  • EXCEL’s unique thermoplus insulation has an extremely high insulating value that helps to keep flue gasses hot. Creosote won’t condense in a hot flue.
  • EXCEL is the lightest weight insulated chimney of its kind on the market. This low thermal mass enables it to heat up quickly, reducing creosote formation. And EXCEL’s light weight helps make it the easiest chimney to install.
  • EXCEL incorporates continuous blanket insulation into a design which eliminates couplings between lenghts. This means there are no hot spots on the outside, or cool spots on the inside.
