How to measure for your Chimney Sheep

You’ll need:
  • 1 x head torch or regular torch
  • 1 x tape measure
  • 1 x chimney

Step 1: Take a look at your chimney flue

  • Use your head torch or prop your regular torch so you can see up your chimney.
  • Mind out for soot getting in your eyes – if you really want, you can put a pair of swimming goggles on!
  • Each chimney flue is unique – some are round, some trapezium shaped, some square – and yours may well be different from your neighbours! Depending on the shape of your flue, depends on how you measure but don’t panic, we’ll talk you through it.

Step 2: Locate the nearest, narrowest opening of your chimney flue

  • Regardless of the shape of your chimney flue, your Chimney Sheep always needs to go in the nearest and narrowest opening to you.
  • For those of you that have fire surrounds, don’t try posting it through into the main chimney. Remember, nearest and narrowest opening (trust us, you’ll save your back and shoulders this way!).

Step 3: Measure your flue

  • It’s now time to measure your flue! This is where the shape of your flue becomes important…
  • If you have a round flue: use your tape measure to measure the diameter. You want a round Sheep that is an inch or so larger than the flue so it wedges in nicely.
  • If you have a square or oblong flue: use your tape measure to measure the depth and width of the nearest, lowest opening. Again, you want a Sheep with depth and width measurements that are a couple of inches larger than your measurements so it wedges in nicely.
  • If you have an ‘odd-shaped’ flue (D-shaped, trapezium, or any other weird and wonderful shape): don’t let an odd-shaped chimney flue worry you. All you need to do is measure the largest depth and width measurements of the opening (so the longest and widest bits of the shape). When you come to insert your Chimney Sheep, the wool felt will just squash and fold into the narrower parts of the flue to fit and create a nice seal with no gaps. Again, you want a Sheep with depth and width measurements that are a couple of inches larger than your measurements so it fits snugly.

Step 4: Choose your Chimney Sheep!

  • Input your measurements into our sizing chart and hey presto, you’ll know which sized Chimney Sheep you’ll need!
  • We have tried to ensure there is a Chimney Sheep for all chimneys but just like humans, chimneys are all different so inevitably there will be some chimney flues that don’t match our standard sizes. If that happens to be you, don’t panic! We can make bespoke Chimney Sheep! Contact us with your chimney dimensions and we can give you a quote.

Step 5: Check the height

  • Your Sheep will come with a 15cm handle and 15cm extension rod giving 30cm of reach altogether. It’s important to make sure the safety dangle is visible so buy more extension rods if you’re pushing it more than 30cm up the chimney
  • It’s easier to fit a large sheep lower down than a small sheep high up.
