Two boats. Two stoves. Big stove on small boat - Morso squirrel. Smaller stove on bigger boat - Stovax stockton 3. Both have same dia flues which need to stay with their boats as one is straight and one is dog leg. Both have flue reducing collar things on stove top. Up to top of collar on morso is 65mm higher than stovax, otherwise I think it's a straightforward-ish job apart from both weighing in around 70kg. Swapping the reducing things which are slightly different in height, if it's even possible, wouldn't be enough to make up the gap between the shorter stove and the rather expensive looking dog leg flue. The hearth is already raised. I'm guessing that it's anyone's guess how far the flue is inserted into the reducer thing, it might be enough to make up the difference. Here I'm ignorant as never seen them in pieces. Is it a mad idea to swap them? Is there an easy way to find out how far the flue is fitted inside the reducing collar on the stove? Thanks for reading.  |

If this reducing collar would slip down 50mm and also fit the other stove I think I'm in business.  Seems too easy, I must be missing something. Hmm... |

Just like that, it doesn't seem that you're missing something, and your idea should work as far as I can see (from a long distance).

The squirrel was due for a clean up ready for the winter + I wanted to see how far the flue overlapped inside the collar. Out with the baffle plate, but another bit fell out too. It's the half moon dished bit pictured in the bucket.  Ever wish you hadn't started something? It had fallen off because one of the lugs that hold it in place has broken off, or rather the screw that held the lug onto the inside of the stove top is broken. Good on left...  Missing on right...  I'd like opinions on whether this bit it strictly needed, it seems like it's another baffle to cause the smoke/gasses to turn just one more corner on their way up the chimney? |

Bloody typical, it's not shown on the exploded parts diagrams I can find, though it looks like a Morso Badger has one. The badger diagrams are too fuzzy to read the part number.
It would be good even to find out what it's called as it's name presumably describes it's purpose.

Ah-ha, finally tracked down what it is, it's known as a smoke shield/ draught reducer.
Because I'm hoping that binning it will be ok, I'm inclined to think reducing the draught on a short, undersize narrowboat stove flue is counterproductive anyway and I might even be better off without it. Wishful thinking?

Accepting all stoves are designed differently I would just say our Charnwood C5 has nothing at all after the top baffle plate. When I take it out to clean it there is totally unrestricted access up the flue, I guess not replacing yours may in theory create less restricted increased draught up the flue so could perhaps lead to the stove being over fired??, but (again in theory) you could control this with the air control(s) on the Morso.
(usual disclaimers apply of course)

I was chatting with a moorer today, telling the sorry tale. His first remark was "I was told by my installer that those shouldn't be fitted on narrowboat stoves".
I've put it back together without the plate, made up a fire and it did draw better from cold. Maybe. It's marginal. I suppose the real test is whether it turns into a furnace in the wind, but like Martin I can't see that happening.

Isn't it an anti downdraft flap sort of thing that cuts the bulk when it's windy?
Shitty dirty log burner crap chuck it in the skip is my advice!

It's got as far as the ash bucket, fire lit, all is good. Did you hear I went to Tarleton in the 50 footer? 🍺🍺🍺 Drove it back pissed as farts in the dark/mist. 👍 |

Flue damper.
I retrofitted one to one of my fires. It means you can slow the fire down more than if you didn't have one, by partly closing off the flue. Can be a dangerous thing to have in the flue though if it gets blocked which is partly why I have 3 CO detectors.

I could put the fire out when it was fitted so maybe a tad unnecessary in my particular installation? Thanks for the info. |

The stove I fitted one on has no rope seals on the doors (because it was made well and does not require them) and as it is a cooking stove with a large hotplate it also has an expansion gap in the top. So its not airtight. A stove like this needs to have a diligent owner (me) but its a great stove I really enjoy interacting with it.
I wouldn't have thought a flue damper would be needed on a squirrel as they are pretty much air tight.
And yes they (dampers) are dangerous if you subtract the "diligent owner" bit. That would explain official advice not to fit them because not every fire user will fully understand the purpose or dangers.

Rayburn type cookers have them, ours did (£5 bargain many years ago), if you mean an adjustable damping plate. This one (bad picture earlier) is like half a breakfast bowl and permanently fixed. It more creates a sharp corner in the flow to slow it rather than reducing the flue size (by much). |
