Chimney liner installation for homes in Lake Nona

Factory-built units listed for masonry chimneys

Factory-built chimneys or chimney units listed for installation within masonry chimneys are also accepted by the residential code. These are complete manufactured systems rather than a flexible liner alone, and their listing sets the clearances, the parts and the way they are supported.

We raise this route when a chimney's shape, its height or an appliance's needs point toward it, and we explain how it differs in plain terms before you choose. The estimate names the product either way, so there is no doubt about which system your chimney received.

The fuels a listed liner is made for

Stainless flexible liners are listed for venting the products of combustion from appliances burning oil, gas or solid fuel, within limits written into each product's instructions. Those limits include a maximum continuous flue gas temperature.

The limits are part of the listing, not fine print. We match them to your appliance and write the fuel and the product together in the scope. If you later change appliances, that line in your paperwork is the first thing to check against the new unit's needs.

One run, or two joined correctly

Where a single length will not do, one manufacturer allows two lengths of flexible liner to be joined with its listed connector. Improvised joints are not part of the listing.

We plan the liner as one run where the chimney allows, and use only the connectors the instructions name when it does not. A joint also has to sit where it will not catch the liner on its way down, so its position is planned from the proven route.

How the installation day runs

Relining day follows a set order, and we tell you the plan the day before, including when the fireplace and the roof will be in use and roughly how long each stage takes for your chimney.

• The flue and smoke chamber are cleaned
• The route is proven with a test piece or guide cone
• Insulation, where required, goes on the liner
• The liner is lowered from the top
• The base connection is made and checked
• The top plate and liner cap are fitted and fastened
