CHIMNEY PREPARATION:

 
 

5.) INSTALLING KINGAIR CHIMNEY STAINLESS STEEL LINER FOR A FIREPLACE

 

• No Tee is used on the bottom of the liner when installing a liner for a fireplace application. The Tee is substituted with a Bottom Plate, which is used to seal the liner at the top of the fireplace smoke chamber. The Bottom Plate can be installed by reaching up through the damper opening or by dismantling the face of the fireplace near the top of the smoke chamber.

Installing Bottom Plate through Damper. Attach the Bottom Plate to the liner with stainless steel rivets, stainless steel screws, or a Support Clamp below the Bottom Plate. Once the Bottom Plate is secured to the liner, pull the liner up and place the Bottom Plate on top of the smoke chamber. Hold the liner in place with a temporary support (2x4’s). Install top hardware by placing the Top Plate around the liner and center them both on top of the chimney, secure them to the chimney top with masonry screws, silicone or mortar. Attach the Support Clamp around liner and secure. Push the support clamp tight onto the Top Plate. Place the Storm Collar around liner and push down tight to the Support Clamp and secure. Place a bead of silicone around the top of the Storm Collar to seal. Install the Rain Cap on top of the liner and secure.

Installing Bottom Plate through Face of fireplace. This solution will require more work and masonry skills to rebuild the fireplace. Remove two to four bricks in either the face or the back of the fireplace at the level of the top of the smoke chamber. If the smoke chamber is built correctly there should be approximately eight inches of masonry to go through. Once this opening has been created slide the Bottom Plate into the hole over the top of the smoke chamber. Lower the liner down from the top of the chimney and through the hole in the Bottom Plate. Secure the Bottom Plate to the Liner with stainless steel rivets, stainless steel screws, or place a Support Clamp on the liner above the Bottom Plate. This will prevent the liner from slipping down through the Bottom Plate until the top hardware has been installed. Install top hardware by placing the Top Plate around the liner and center them both on top of the chimney, secure them to the chimney top with masonry screws, silicone or mortar. Attach the Support Clamp around liner and secure. Push the support clamp tight onto the Top Plate. Place the Storm Collar around liner and push down tight to the Support Clamp and secure. Place a bead of silicone around the top of the Storm Collar to seal. Install the Rain Cap on top of the liner and secure. Seal hole in masonry smoke chamber with like material.

6.) INSULATING KINGAIR CHIMNEY STAINLESS STEEL CHIMNEY LINER


Not all situations require the insulation of the chimney liner. The UL l777 Standard for installing stainless steel chimney liners requires insulation because the non-code conforming chimney has zero clearance to combustibles or some other defect. Therefore the UL l777 Standard is in place for fire protection. The definition of a code Conforming chimney is one that meets or exceeds the N.F.P.A.211 standard for construction of chimneys. This standard includes; proper clearances to combustibles, intact 5/8 fireclay flue liner or equivalent, minimum four inch (nominal) solid chimney wall. If the chimney meets all the requirements for a code conforming structure the only reason to reline it would be for proper sizing and appliance performance. In the case of relining gas or oil fired appliances no insulation is required (recommended for high efficiency). Regardless of existing chimney conformance, insulating the chimney liner will improve the performance of the appliance that is connected to it. The insulated liner will stay warmer and the flue will not cool as quickly which means less condensation. In wood burning appliances this will reduce the amount of creosote that will form in the liner. In oil and gas burning applications the likelihood of condensation will be greatly reduced (especially on startup). While fire protection is the main reason for insulating, insulating a liner (even if not required) will pay dividends by increasing performance and efficiency.


Please Note: For the installed liner system to meet UL standards, all UL listed components used must be installed with proper clearances.
