Liners

Metal liners are used to vent appliances through existing masonry chimneys. The type and compound of metal is determined by the fuel. Liners can be rigid or flex, insulated or not, depending on the chimney itself. The size of the liner is determined by the appliance, you can not change the size of the vent (for example a wood stove with an 8" outlet cannot be vented through a 6" liner).

The most common reason for using a liner is when venting a fireplace insert or hearth stove. According to National Fire Code, which is part of NH Fire Codes, most fireplace flues are too large to properly vent an insert or stove, leading to chimney fires. A pipe that goes through the damper and up a few feet into the chimney, then stops, is not a legal installation, and hasn't been since 1987.

Any new installation must conform to current codes. Old installations should be upgraded to current standards for safety reasons.

A properly lined chimney is safer and functions better. 

The reason we will not use poured liners is because of their failure rate. Below are some photos we have taken at customer's homes. These problems were all caused by failed poured liner systems.
