Furnace flue liners
Smaller liners for gas or oil furnaces and water heaters stop condensation from damaging the chimney.
A Clarion chimney sweep can reline your chimney with a liner sized to the appliance and insulated where the system calls for it. Call (814) 538-2091 to reach a local chimney sweep.
Inside most chimneys is a liner, the tube that actually carries smoke and flue gases to the top. It keeps heat from reaching wood framing next to the chimney, protects the brick and mortar from corrosive gases and gives the appliance a flue of the right size to draft well. Some older chimneys were built unlined, and others have clay tiles that have cracked over the decades.
Most liner installations start with one of these situations. Damaged clay tiles, missing mortar between tiles or no liner at all are the most common triggers. Installing an insert, stove or high efficiency furnace often means the old flue is the wrong size.
Before relining, the chimney should get a thorough inspection, usually a Level 2 inspection with a camera run up the flue. The inspection tells you whether relining is truly needed and what kind of liner suits the chimney. Ask to see the camera video so you understand what was found.
Chimney Liner Installation is often paired with chimney liner repair and chimney inspection, depending on the cause.

Call nowA liner has to fit the flue, the appliance and the chimney route.
A camera is run through the flue to check the existing tiles, offsets and obstructions. This confirms what kind of liner the chimney needs.
Sizing follows the appliance it will serve, since too big or too small both cause problems. The route and any offsets are noted.
Creosote and debris are cleaned out first, and broken tiles may be removed to make room. The path from top to bottom has to be clear.
A flexible liner is fed down the flue, while rigid sections are joined as they go. Insulating it helps draft and reduces creosote and condensation.
A tee or connector joins the liner to the appliance, and a top plate seals the crown. The connections keep gases from leaking into the old flue.
A draft test confirms the new liner is working. Keep carbon monoxide alarms on every level of the home.
Smaller liners for gas or oil furnaces and water heaters stop condensation from damaging the chimney.
Rigid stainless sections join together in straight chimneys which suits wood burning appliances well.
A cement based mix is poured around a form inside the chimney to create a smooth new flue in a single solid lining.
A flexible liner works in chimneys that are not perfectly straight which makes them the most common relining choice.
Liners can be insulated with a blanket or a poured mix where the system or chimney calls for it.
Most relining jobs use stainless steel, which handles high heat and corrosive flue gases well. Flexible stainless goes around offsets in a chimney, and rigid stainless suits straight runs. The sweep picks a grade of stainless that suits the fuel the appliance burns.
Insulation around the liner helps flue gases rise and keeps the outside of the chimney cooler. At the top, a sealing plate and cap keep rain and animals out. Many Clarion chimneys get a stainless liner when an old fireplace is converted to an insert.
Relining means putting a new liner into a chimney that has an old, damaged or missing one. The most common triggers are chimney fires, settling cracks, missing mortar and appliance changes. Most chimneys can be relined from the roof without opening walls.
Have a list of everything that uses the chimney ready when you call (814) 538-2091. A furnace replaced with a high efficiency model that vents through the wall can leave the water heater alone in an oversized flue, which leads to poor draft and condensation. A smaller liner brings the draft back where it should be.
Around Clarion, relining usually comes up when a home changes heating appliances or an inspection turns up cracked tiles. From Clarion out to places nearby like Marianne, Knox, Rimersburg and New Bethlehem, wood stoves and inserts are common, and each one needs a properly sized liner, and a new liner is often the safest long term fix.

Winters here are long and cold, and the heating season usually runs from October well into April. Masonry takes the worst of it from the freeze and thaw cycle: rain and melting snow soak into the crown and joints, then freeze and push them apart, and each winter widens the cracks a little more. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. Most homeowners in Clarion, PA schedule a sweep in early fall, and a repair check after a hard winter.
Small chimney problems caught early usually stay small repairs.
