Question

What does the 1" inch clearance to combustables mean?

I would like to use this to vent a wood stove. What is meant by: "Minimum Clearance from Masonry to Combustibles - 1.00 inch"
My masonry chimney runs right up against the side of my house which is technically combustible, is this an issue?

Do i need to inspect the sides of the chimney somehow?

Staff Answer
Before installing the DuraFlex SS Liner system, the chimney passageway should be examined to check for cracked, loose, or missing bricks, mortar, or other materials that could inhibit correct installation of the liningsystem. The Chimney should be cleaned and any tar glaze creosote removed. Verify that the existing masonry chimney has at least 1” clearance from exterior of the chimney to combustibles and it meets current NFPA 211 requirements as well as any local code requirements.

Staff Answer
The chimney liner should be inspected by a certified chimney sweep or qualified chimney inspector prior to each heating season. When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. As a result, creosote residue accumulates on the chimney liner. When ignited, this creosote makes an extremely hot fire. If you are burning solid fuel, the chimney liner system needs to be inspected at least once every two months during the heating season, to determine if a creosote or soot buildup has occurred. If creosote or soot has accumulated,it should be removed to reduce the risk of a chimney fire.To remove creosote and soot, use a wire or poly chimney brush. The size of the brush should be the same diameter size as the liner or up to 1/8” larger. Thoroughly brush the liner to remove any buildup that may have occurred. To access the liner, remove the top portion of the cap by removing the screws on the legs.
Be sure to reattach the cap after cleaning liner

Staff Answer
The DuraFlex Stainless Steel Flex Pipe is intended to be installed by dropping it down from the the top of the masonry chimney and it would be difficult to manipulate it through an opening that is not 6 inches in diameter without damaging it. Always check with local codes and ordinances to be sure you are in compliance.

Staff Answer
The DuraFlex Kit is designed to convert an existing masonry fireplace to accommodate an insert. Any additional hardware would be determined by the unique characteristics of the fireplace itself and/or the insert being installed. Always contact your local Fire Marshall to make sure you are in compliance with local codes and ordinances.
