Retro-fit plume kit....

[lastminute]

I need to divert the boiler flue on the side of my house which is situated under a carport.
The flue is within a foot of the carport roof. Would using an elbow and fitting it through a hole in the plastic roof be safe and ok?
I intend using a retro-fit kit (Screw fix stock them)
I have asked 2 gas fitters to do the job, but they both failed to turn up!..job too small!!
I hope and presume its ok for me to fit..or does it require a qualified person?

If it's a balanced flue I would want to get the gas/air mix checked after making changes, as adding an elbow could reduce the amount of air coming in and result in incomplete combustion.

I am about to do this to my glow worm system when the weather gets a little warmer.
As I understand it the plume kit is a plastic pipe which is connected to the inner pipe of the flue (the bit where the steam comes out)
A 90 degree bend is used to connect to this inner pipe, and lengths of pipe are used to give the height req.
The top of this pipe is then capped with another 90 degree bend to stop any water entering it.
The flue air intake is not affected by fitting the flume kit.
I intend to get my kit from Plumbnation, who will give you all the information you will need.
I am not a Gas safe reg person but I am competent in what I take on.
You can see this flue fitting on Youtube

Avoid 90 degree bends wherever possible, use 45 degree. Its very important to consider exactly where the flue will terminate. It cant be near an opening window or on the edge of a house or level with a roof due to cross winds.
Try to get a BOILER QUALIFIED gas or plumber to either do the job, or to give you precise instructions (Gas qualifications are so varied that a man can be gas safe registered but not have a clue about flues).
If its a balanced flue (pipe within pipe) then there is minimal fire risk but still it should not be in contact with a combustible material. If its a single flue pipe then even more care is required to prevent a fire.

There are detailed dimensions for flue positions stipulated by building regs, including distance from combustable materials, distance from windows, distance from neighbours.

Building regs also state boiler manufacturer approved flue specifications should be adhered too.

Building regs would expect work to be approved by HETAS registered heating engineer.

I know, all a bit officious, just pointing out the approved route......

My dad had a new balance gh boiler fitted, the flue ended up 6" from the neighbours porch :shock:

You'll have to forgive those of us who have low regard for "fully qualified" fitters.

There's a six-storey block of flats behind us. Several have had boiler replacements, and one of them has its condensate pipe discharging down the outside brick wall, three or four floors up. The stain is impressive, and it won't be long before it's seriously damaged the brickwork. Similarly, one of the flats right next to our house has the flue sticking out from the wall horizontally by about 15 inches, for no obvious reason.

Our own heating engineer is excellent, but then he's a former colleague who retrained after we were both made redundant from a high-tech industry. He was a team leader in the six-sigma and BS5750/ISO9000 processes.

I see a lot of really dodgy work, both plumbing and electrical - things which are either wrong because the tradesman cut corners for convenience (like the flues and drain pipe above), or simply because they were stupid/ignorant. Don't get me started on dumb electricians!

The other classic is treating plumbing or electrical fittings as a grown-up's Lego set. Stuff thrown together because the correct fittings weren't available.

My friend tells me that when he did his apprenticeship/training at what was then a local technical college, his class was about 70% long-term unemployed, who had no interest in plumbing and didn't actually want to work but had been sent on the course as a condition of benefits continuing. They made life rather difficult for the lecturer, and the students who did want to learn and who had paid to be there.

Ho hum.
