ICC warrants its stainless steel chimney liner to be free from functional failure due to defects in material or workmanship for as long as the original consumer owns the chimney system. This warranty provides for replacement of any stainless steel components, except rain caps, which fail as a result of normal use with a residential freestanding fireplace, wood burning stove, furnace or boiler, including damage to the liner due to a chimney fire. This warranty does not cover damage caused to the original masonry chimney, or to the building, by chimney fires or misuse of the product.

Note: Chimney fires are dangerous and preventable, we strongly encourage you to have your chimney liner cleaned regularly.

ICC will only be responsible for repair or replacement of stainless steel components found to be defective under this warranty. In no event shall ICC be responsible for any incidental or consequential damage caused by defects in the stainless steel chimney liner system.

During the first ten years of the warranty ICC will repair or replace any defective stainless steel components, except rain caps, at no charge. For the balance of the warranty ICC will provide replacement stainless steel components at 50% of the current retail price at the time of the warranty claim. To obtain service under this warranty the defective liner should be returned to the dealer from whom it was purchased.
