| Left: Minimum requirement. If the chimney is properly lined with terra-cotta liner tiles measuring 8" x 8" or smaller, a direct-connect installation is permitted. Remove damper assembly, cut and anchor a stainless steel sealer plate (removable for cleaning) at the throat of the fireplace. Insert a length of 6" stainless pipe long enough to reach into the bottom liner tile through a hole cut in the sealer plate.Advantage: less expensive than full relineDisadvantages: reduced updraft, increased creosote formation, insert must be removed to clean chimney. |
Right: Preferred method, and required for zero-clearance fireplace installations or if existing chimney is unlined, if the liner is cracked or damaged, or if the flue opening is larger than 8" x 8". Remove damper assembly, install a 6" stainless steel liner the entire length of the chimney, passing through a stainless steel sealer plate at the top of the chimney; finish at top with stainless top clamp, storm collar and rain cap.Advantages: better updraft, better performance, reduced creosote formation, chimney can be cleaned without removing insert.Disadvantage: more expensive to installTo read more about installing your stainless liner, click here. |
