Air and Water Tight
This seven ply seam locks moisture and flue gases in your chimney and keeps them from
leaking into the home.
Guards Against Corrosion
Forever Flex™ certified stainless steel liners protect against hostile acids which deteriorate
masonry chimneys.
What About Creosote?
Forever Flex liners do not allow creosote to leach though the liner, unlike masonry flues. This
creosote can catch fire, and lead to a house fire. Thanks to Forever Flex, this harmful
creosote is contained.
Seals Off Carbon Monoxide
Forever Flex™ protects the structure of the home from moisture damage and the very real
potential of carbon monoxide poisoning.
UL listed and Tested
Full UL tested and listed to UL 1777 standard by Underwriter Laboratories, the most
recognized and respected testing facility in the world.
Forever Warranty
This is the best warranty in the world, transferable to the next homeowner. Makes you feel
good about your purchase with the true Forever Warranty.

• 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 chimney to pass the ULC standard.
• EXCEL’s unique thermoplus insulation has an extremely high insulating value that helps to
keep flue gases hot. Creosote won’t condense in a hot flue.
•EXCEL is the lightest weight 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 lengths. This means there are no hot spots on the outside, or cool spots on the
inside.

NEVER, EVER BUY ANOTHER STOVE PIPE
Only ULTRABlack is covered by a true, no questions asked, 100% full replacement, LIFETIME
WARRANTY
Hi-tech Performance - Old Fashioned Appearance
Double Wall Construction with a 3/8” air space between inner and outer pipes provides superior
insulating value to single wall pipe. Better insulating value keeps flue gas temperatures higher.
This helps your woodstove perform with an enhanced draft, which provides:
• less chance for moisture or soot build up within the vent
• reduced smoking of the stove at start up
• increased efficiency
• ULTRABlack not only keeps the flue temperatures higher, it keeps the outer pipe
temperatures cooler. This allows ULTRABlack to be installed with only 6” clearance to
combustible materials. Single wall stove pipe requires an 18” clearance, which typically means
your wood stove sits further away from the wall and takes up valuable space within the room.
