Well spotted. Remember that there are a lot of stupid people involved with chimneys. You are absolutely right. If the stove has a male socket, and you have to drop the female socket OVER that, then the whole sodding flue will be upside down, and creosote will be able to leak out of every joint, and before you ask, no, you can't seal the joints.

The solution is comparatively simple, but expect to get a lot of tutting and sucking of teeth when you explain it.

You need to get someone to weld up a specialist joint that will fit inside the male on the top of the stove (ie a sub male size) that then widens out to a female socket. Having thus cured the basic stupidity, you can now drop the male end of the first flue pipe into the female end of your adaptor.

There will doubtless be some moron who will try and tell you this is all wrong and the that flue pipes are supposed to go the other way up. This is because they are morons. They will need this carefully explained to them as they are almost certainly too stupid to reasise just how dumb they are.

If you want to make such a joint, it is simply two cylinders of steel, one with the internal diam equal to the internal diam of a female socket and the other with and EXTERNAL diameter equal to the INSIDE diameter of a male. Just weld them together so they are airtight when connected.

Remember to keep thinking to yourself "Deep blue ocean, deeeeepp blueee ocean" over and over again.

God loves stupid people. Why else would he make so many?

Best of luck

Thanks Bil I thought I was right in my thinking, but try telling the Spanish this or for that matter a few on here.

I was rather expecting to be put in my place by the real know alls on here

Every stove I have seen to date in Spain has been fitted incorrectly

To be fair to folk if this is what they are told and they don't question it, it's bound to happen.

bil

Naaah, not on a technical point.

Had you queried if it was socialist practice to put them that way up, we would have had someone blaming Labour for the fact that tar flows downhill, whle I would be blaming the bastard tories for everything.

The problem with installers and so on is that they have been doing it that way for years, and are not about to change for some bloody guiri.

Take heart, 30 years in the UK I spent bitching about that and there were still builders and installers who would swear blind to customers that I didn't know what I was talking about.

bil

Yep, good point.

In 30 years of working on flues and chimneys I never once saw a single flue pipe passing thru a wall that was fitted correctly.

Not one.

Yes and they are dangerously incorrect IMO in Spain.

Are you sitting comfortably next to yours?

In the UK I used to keep a diary of breaches of Building regs and British standards wrto fume and fire risks.

On average we clocked up 1 breach per appliance, that's about 8 a day, the record was 11 on one appliance.

I quit doing it when I went to one house where the stoves were installed lethally, a damn near terminal fire risk, and when I asked the lady of the house, she told me the previous owner had done it. His profession?

Building regs inspector for the area.

That's when I stopped the diary.

What was the point?

bil

Yes, because I had one of those special connectors welded up.

anonimouse

Well done Bil.

I bet there's loads on here checking their installations tonight hoping to be able to take a pop

bil

No, because what would be the point? It would be like trying to argue that water flows uphill. All anyone has to do is read Building Regs Approved Document J and it's in there.

[QUOTE=bil and before you ask, no, you can't seal the joints.[/QUOTE]

Fire cement
High temp proof paint
Exhaust repair paste
Clamps around the joint.

Been there, tried them all. Nothing works. It will eat through anything.

My solution was to replace the lot with double skinned insulated tube.
The first piece is a cone shape, only around 8 inches long that fits narrow end down over the male bit on the top of the fire. All the other tubes sit on top of this with there own fitted clamp.
You will never see this type of tube in the showrooms, it is a secret that you have to know about. Ask for "tubo aislado" And they will raise an eyebrow and tell you that they have it, but nobody ever buys it as it costs about 5 times more than the single skinned tube.
Well worth the extra cost IMO.

Ours has now been fitted for 4yrs without any leaks.

Thought you had a welder yourself bil. Put me on the list when you decide to start your stove flue pipe widget business!

bil

Spot on. Joints can't be sealed, because the metal will flex and expand like a mad thing when it is heated. Our physics teacher demonstrated how that force will shear a cast iron pin effortlessly.

The double skin works because each length has a good sound joint, but there is still a correct way of fitting it, and a wrong way. The junction that connects to the stove should still ideally go INSIDE the stove's socket. Also, be very careful never to have a chimney fire as the steel inside will denature and rot if it is exposed to temps that high.

The only disadvantage of it is that it does mean you get less heat in the room as more goes up the flue. This double tho is EXCELLENT for where the flue goes thru a wall or a ceiling as it won't expand and crack the plaster, and is ideal for outside, in fact, you shouldn't use the single skin outside. I don't care how many people do, it's still wrong.

bil

Wel, I got that done for me by a friend, as I wasn't going to be there when the stove was delivered, and he was fitting it for me.

The huge problem with simple, effective solutions is that people don't value them, and then won't pay enough to make it worth your while.

I'd say to you, when you have the money, buy a cheap arc welder and get a good helmet that has one of those clear glass windows that darken automatically. Then start to teach yourself how to weld.

There are good basic books, and even if you weld badly (like I do) you can clean it up with a grinder and cover your mistakes with paint!

I told OH "Bil's trying to get me to buy a welder". He said "you know you wanna".... He's right. I'm a tool junkie. Can't afford either welder or metal right now. But maybe it's creeping on to the list.
Latest purchase was a winch from Lidl. German engineering! Lidl does it for me. Means I can buy cheap....and European!
