Two flues, one new appliance

When a chimney carries two flues and only one is being relined, the job has to respect the other. The liner goes into the flue that serves the new appliance, the second flue is checked and swept, and the masonry wythe between them is looked at wherever it shows.

Up top, a single cap may have covered both flues. With a liner cap now on one of them, the old cap on your O'Neil chimney may no longer fit, so we check whether it can be refitted or needs a new arrangement. If the second flue sits idle, a screened cap or a cover keeps it from collecting debris. Call (904) 920-5495 and a liner specialist will measure your O'Neil flue for free.

The county for O'Neil is Nassau County. The coast is close to O'Neil.

Sweep, prove, size, reline

Sweep and prove the flue
The flue is swept clean, then a test piece or cone is lowered to make sure the liner will pass every bend.
Size and alloy chosen
The diameter comes from the appliance collar or the fireplace opening, and the alloy from the fuel.
Liner run down and joined
The liner goes down with its insulation where the listing asks, and joins the stove, insert or smoke chamber below.
Top plate, cap and record
The top plate is clamped and sealed, the cap fastened, and you get the installation record.

Relining a short way from the coast

O'Neil is near the coast, where salt still settles on the top plate and cap of a liner. Stainless parts with matching fasteners hold up to it.

The liner cap and plate on your O'Neil chimney are listed by metal and model.

Old tile standing above the crown

Old clay tile can stand a few inches proud of the crown. If it is sound, one liner maker's instructions allow it to stay, with the top plate and cap fitted over it.

If it is cracked or crumbling, it is cut back flush with the crown using a chisel, taking care that pieces do not fall down the flue, and any that do are removed from the bottom. The cut surface and any cracks are filled with mortar so the top plate sits flat and seals against the masonry. The top is checked for level before the plate is set, whichever way it went.

When the flue is too big for the appliance

An oversized flue causes trouble too, though it shows up differently from an undersized one. Exhaust slows down in a passage much larger than the appliance's collar, loses heat to the extra surface, and condenses. The result is heavy creosote with wood and damp, acidic deposits with gas.

Liner makers set a floor and a ceiling for liner size: no smaller than the appliance collar, and in one maker's instructions no more than three times its area for solid fuel. A liner inside the oversized flue restores the right size without changing the masonry around it. The collar size and the liner size are shown side by side, so the fix is easy to check.

Sizing a liner for a gas appliance

Gas appliances are sized differently from wood. The flue for a gas appliance vented into masonry is sized from the venting tables in NFPA 54, the National Fuel Gas Code, and from the appliance's installation manual, and the Florida Building Code sends gas flue lining to its fuel gas chapter.

The tables account for the appliance's input, the height of the chimney and the length of any lateral run. Too large a liner lets the exhaust cool and condense; too small restricts it. When two gas appliances share a flue, the combined sizing rules apply, and we note which table was used. The appliance's rating plate gives the input figure the tables need.

Relining questions from O'Neil

Do you install chimney liners in O'Neil?

We do. Describe the fireplace or stove and the reason relining came up, and the O'Neil estimate visit is planned around it.

Does a relined flue still need its own cap?

The relined flue does not need one. The liner kit we fit includes its own cap, which fastens at the top plate. If the chimney has other flues, their caps are checked, and any change is noted.
