What the numbers suggest for chimneys in Readington

Census estimates show about 63% of Readington's 6,376 occupied homes heating with utility gas, 20% with fuel oil, 8% with electricity, 5% with propane and 2.6% with wood. Oil and wood both leave deposits in a flue, and the oil furnace and boiler flue guide traces what years of oil exhaust do to clay tile.

The housing stock is older than much of the region: 11% of units date from before 1940, 11% from 1940 to 1959 and 25% from the 1960s and 1970s, with 40% from 1980 to 1999. A brick chimney of that period may carry two or more flues side by side, for instance a fireplace passage next to a heating passage.

About 75% of units are detached houses and 14% attached. None of these township-level figures tells you how your own chimney is doing.

Can your chimney take a stove? Five checks in order

Wood stove manuals spell out what the chimney must provide. The figures below come from one example, the Jøtul F 400 manual; your stove's own manual is the one that governs.

1. A flue of its ownThe manual says not to connect the stove to a chimney flue serving another appliance of any kind. If your only open flue serves the oil boiler, you need another flue, a new chimney or a different venting route.
2. The right flue sizeThe flue should be no smaller than the stove's flue collar and, per that manual, no more than three times the collar's area for a chimney with no exterior walls or two times for one with exterior walls. A larger flue, such as an old fireplace flue, should be relined with a listed liner; see chimney liners.
3. Enough heightThat manual sets a 15-foot minimum overall chimney height, with the top standing 3 feet or more above the spot where the chimney exits the roof at its highest.
4. A sound flueIt asks that an existing chimney be inspected by a professional before installation. Under CSIA's inspection levels, adding an appliance is one of the changes that makes a Level 2 inspection the right scope.
5. A proper connectionThe connector slides fully into the thimble to the inner face of the flue liner, uses black or stainless pipe of at least 24 gauge, rises at least 1/4 inch per foot on horizontal runs, and has each joint fastened with three screws. Our guide to thimbles and connector pipes explains the parts.

Choosing the stove with the chimney in mind

EPA's Burn Wise guidance recommends looking for the EPA certification label and notes that the emission limit for new stoves dropped to 2.0 grams per hour in May 2020. It also stresses sizing the stove to the space it will heat, from small units for a single room to large ones for open plans and older houses in cold climates. See EPA-certified wood stoves.

Bring the chimney into that decision early. A stove whose flue collar suits your existing flue, or one that will be paired with a properly sized liner, avoids surprises on installation day. If you have a working fireplace, compare a freestanding stove with an insert in our guide fireplace insert or freestanding stove?
