"It's a super thing"

A. Kelly, Knockboy, Co. Waterford


Note: An approximate guide only - applies to the date the chimneys were built.
Regional variants tend to be smaller in the northern or coal mining areas.

It is best to measure (about a foot above the opening, inside the chimney) to make sure.
To go higher up, ask for an extra-long handgrip, 14" long.
Note also handgrip extension with tap on end, adding 16" to handgrip length.
Standard Sizes:
S: Lined flue One(7" to 9" dia)=9"x9" or Small=15"x9";
M: Lined flue Two=12"x12" or Medium=24"x12";
L: Large=36"x15".
Some old chimneys deteriorate and may have been lined recently to prevent leakage of fumes. The 9"x9" fits these.
Chimneys originally built for a kitchen range often narrow quickly to 12"x12". The 12"x12" chimney balloon obviously fits here.

Date Built
Up to 1800
Generally, chimneys before 1800 are wider from front to back than later ones,
so they need to be measured and the chimney balloon made to size. Expect common sizes such as 36"x24", 36"x18", 24"x16". See also Inglenooks below.

1965 on Chimneys after 1965 have liners. There are two types, either 8" to 9" diameter or 11" to 12" square.
Some liners are too far up to reach, and instead a Small, 18"x12",
or Medium can be fitted in the space just above the fireplace opening.
Canopies Normally, a C.B. can be fitted at the top. It will usually be somewhere between Small and Medium, but may be an odd size. Avoid any jagged edges of metal or the sharp ends of screws.
Inglenooks If the chimney gathers (tapers) slowly, you can fit a C.B. in a fairly accessible position. We can supply extra-long handgrips to reach. Sometimes there are two metal bars in the chimney, just above is a good place. 'Younger' Inglenooks (250 years) normally gather fairly quickly, it is best not to put a C.B. in the gather. Where the flue passes the floor above is smaller and this is the best spot. Expect around 3' x 2'.
* Sometimes a Medium C.B., but some chimneys around this time were made wide and slim to keep the chimney breast from jutting into the room. They vary around 30" x 10" and are tailor made (Price same as Large).
# Usually small, but where a back boiler was originally fitted (usually a back room), it will probably be a Medium.
