CHIM-FLEX Chimney Liner Systems

IMPROVE YOUR DRAFT TODAY.

Nearly all heating appliances rely upon the draft created by a chimney to operate. Many of todays high efficiency wood stoves are particularly draft dependent due to their use of catalytic combustors and secondary combustion chambers. Furthermore, clean glass air wash systems are also dependent upon high levels of draft in order to maintain the best fire viewing.

CHIM-FLEX chimney liners improve draft by properly sizing the chimney to your appliance. Changes in the volume of a venting system can have a detrimental effect upon draft. By installing a CHIM-FLEX chimney liner, you create a constant velocity flue. This means there is no change in the size of the venting system for your wood stove from the exit point of the stove to the exhaust point at the chimney liner cap. CHIM-FLEX chimney liners also improve draft by containing heat within the chimney liner. Hotter flues draft better. By installing a CHIM-FLEX chimney liner, you create a venting system that remains much hotter than a conventional masonry chimney. This is enhanced when a high temperature insulation layer is installed. By creating a constant velocity flue that remains hotter than a traditional masonry chimney you have a venting system that is ideal for venting your wood burning stove.

REPLACE A CLAY FLUE TILE LINER ENTIRELY.

CHIM-FLEX 316L Stainless Steel chimney liners are tested and listed by Underwriters Laboratories to function as a full flue tile replacement. In a situation where no flue tile exists and the masonry chimney structure is at least four (4) inches thick, CHIM-FLEX 316L stainless steel chimney liner can be installed with 1/2 inch of CHIM-WRAP insulation to bring that chimney up to the National Fire Protection Association 211 code.

KEEP IT CLEAN, KEEP IT SAFE.

A CHIM-FLEX 316L Stainless Steel chimney liner is a venting system for your wood stove that makes your home a safer place by design. Performance of your wood stove is optimized through enhanced draft. When your wood stove is operating at its best creosote creation is minimized. Creosote condenses only when it cools. The warm internal surface of your chimney liner prevents creosote adhesion within the liner system. When you combine reduced creosote creation and prevented creosote adhesion, your have the cleanest and safest venting system available for your wood stove. There is no better way to stop a chimney fire then to prevent it before it starts!

PROTECTION WHEN YOU NEED IT.

CHIM-FLEX 316L stainless steel chimney liners are expertly manufactured for structural integrity even under the worst of conditions. CHIM-FLEX 316L stainless steel chimney liners are tested and listed by Underwriters Laboratories to the stringent UL1777 standard. This testing procedure requires that an extended burn, simulating a tremendous chimney fire, be contained. It also requires heat transfer from the extended burn fire be minimized. Please see our installation instructions for a complete description of insulation requirements.

316L stainless steel is our alloy of choice for the manufacturing of CHIM-FLEX chimney liner for all fuel venting. We chose 316L because of its high level of strength under the most extraordinary of heat conditions and its inherent high level of corrosion resistance. We are so confident in both the quality of 316L and our expert manufacturing that we offer our LIFETIMEplus WARRANTY on CHIM-FLEX 316L stainless steel chimney liner when it is installed to vent wood, gas, oil and coal appliances.
