*The Ti in 316 Ti stands for Titanium, which is added to the composition of the stainless steel. Titanium stabilizes the alloy at extremely high temperatures of 700 degrees and above, which can occur during a chimney fire. Titanium combines with carbon, preventing the precipitation of chromium carbide from the material, which in turn limits chromium depletion and susceptibility to corrosion. A 316 Ti alloy can be held at higher temperatures longer before sensitization occurs than in a non-stabilized alloy like 304L or 316L. |
Sizing Your Chimney LinerThe ideal size for a stainless liner is the same diameter as the exhaust opening on the appliance. If the liner is too small, it may not allow the exhaust volume necessary for efficient operation. If it is too big, it may draft too slowly at startup, and develop too much updraft when it finally heats up.To read more about flue undersizing, click here.To read more about flue oversizing, click here.A possible exception: If the appliance has a 6" flue collar and there isn't room in the existing chimney flue for a 6" liner, consider using a 5.5" liner. For chimneys at least 20' tall, this slight size reduction almost always works. |
To Insulate, or Not to Insulate?Our Top Sealer Plates seal so tightly, they virtually prevent the flow of air up the flue around the outside of the liner. This creates "dead air insulation" around the liner, and in most installations in code-approved chimneys, no further insulation is required. There are some instances, however, when additional insulation is recommended or even required.
