Excel is tested and listed by Warnock Hersey Professional Laboratories to safety standard
UL 103HT - The standard for solid and liquid fuel chimneys installed in the USA.
ICC 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.
