How to measure for a Chimney Sheep®
To ensure that you get a Chimney Sheep® chimney draught excluder that works effectively, you’ll need to ensure you get the correct shape and size. To get the right shape and size chimney draught stopper, you’ll need to measure your chimney flue. Don’t worry, it’s pretty simple. You can watch our ‘How to measure’ video or follow our simple step-by-step instructions below. Measuring your chimney can be a bit of a messy job so we recommend you don’t wear your Sunday best!
What you’ll need for this
Step 1
Take a look at your chimney flue
- Grab your head torch or prop your regular torch so it lights up your chimney flue.
- Keeping your tape measure close-by, position yourself so you are able to look directly up your chimney flue.
- Mind out for soot getting in your eyes – if you really want, you can put a pair of swimming goggles or other protective eyewear on.
Step 2
Locate where your Chimney Sheep® will sit
- We suggest the nearest/lowest part of your flue for ease of measuring and installation. The end of the handle will also be seen, stopping anyone lighting a fire when installed.
- If your flue is narrower further up, you can measure higher up. It’s fiddly but you’d be able to get a smaller size and your Chimney Sheep® would work just as well.
Step 3
Measure your chimney flue
- Chimney flues vary in shape. Different shapes have slightly different measuring requirements.
- Round flues: measure the diameter.
- Square or oblong flues: measure the depth and width.
- Unusual shaped flues: measure the largest depth and width dimensions of the aperture.
Step 4
Measure the height
- Next, measure the height from where your Chimney Sheep® will sit to the opening of your flue. This is to ensure the safety tag on the handle is visible which will help to prevent you from lighting a fire when your 'Sheep is in the flue.
- Each 'Sheep comes with a 15cm handle and 15cm extension rod. If you’re pushing it more than 30cm up the chimney, you’ll need to buy more 15cm extension rods. Measuring complete!
Now that you’ve got your measurements...
Find your perfect fit! Input your measurements into the sizing calculator hey presto, it’ll tell you which sized Chimney Sheep® you need. Remember to add the extra extension rods to your order if you need them. The size you need will be a few inches bigger than the dimensions of your flue so it wedges into your flue and stays in place. Any excess felt will squash and fold into the flue to fit and create a nice seal with no gaps.
