Closed carport flue, plume possibility?

[Andrew50]

Hello

I have a Baxi 105e with a horizontal flue that's under a carport, we've now closed the carport at both ends. Am I right in thinking that I couldn't fit a plume kit and take it through the roof as it'll be in a different pressure zone to the air inlet?

What if I had the plume pipe above the carport in a vertical position so the wind would pull the exhaust gases from the exhaust and I fitted an anti downdraft cowl?

This will be easier and cheaper than fitting a balanced flue and cowl. The horizontal flue pipe that is exiting the outside wall now has the terminal fitted right up against the brick so there isn't any extra 100mm pipe to fit the outer pipe of a balanced flue but there should be enough of the inner 60mm pipe to fit a plume.

I realise that you're obviously supposed to get someone someone with the appropriate qualifications.

Thanks

Correct

You can’t get a plume kit for a non-condensing boiler

Yes, otherwise, unless competent, then it’s illegal work.

As above you will not get a plume kit for a 105e they were never made

Thank you. Obviously if I get the correct size plume piping I can get it to fit, I assume the problem when fitting a plume kit to a non condensing boiler is the extra condensate you'll get in a single 60 mm pipe compared to a balanced flue that has the outer 100m pipe providing some insulation that'll help to reduce the amount of condensate?

 

[Andrew50]

If I instead fit a balanced flue to take it up vertically through the carport roof would you know if there are any fittings available so I can leave the horizontal flue in place that is already going through the wall, it's a shame that it's cut so short?

I'll need a vertical flue adapter? These screw to the wall but they appear to be only to take a 125/80 flue to a 100/60 but they don't specify that?

It mustn't be one of those?

You will be hard pushed to find any parts over and above standard horizontal pieces for the 105e these days. You can only use flue parts that are designed for that model of non condensing boiler. Other boiler's flue parts are not interchangeable, especially more modern flue materials.

I also have to add that the boiler flue location etc should have been sorted out before the carport was enclosed, your boiler will probably not be safe to use if it now is.

 

[Andrew50]

Thanks, one end is open and the other end is temporarily as there is a door, there is a good draught blowing through.

I was hoping that there would be a universal fitting to fit on the wall for a 100/60 flue once I remove the 105e terminal.

 

[gas112]

The universal fitting is a new boiler which can take a plume kit
Your 105e is now around 20 year old

Although it still wouldn't be in the right pressure zone but yes a new boiler with a flue terminating in a suitable location is the correct answer here. Or un-enclose the car port, that would also do it

Baxi allow a plume kit in a carport you need a special terminal for the plume kit though to allow for pressure zones
But re reading original post this is sounding like its now fully enclosed and no longer a car port and totally illegal

Thank you everyone.

I have, if I ever build it, a similar situation and came up with a plan to raise a section of roof to create a shared airspace - but I think someone beat me to it:

I've decided that I'll just extend the balanced flue through the carport.

The horizontal flue pipe coming through the wall is aluminium, do I have to use an aluminium elbow to take it up vertically and another aluminium pipe to take it through the carport? I've been on for hours looking for aluminium elbows and pipes but they very rarely specify which material they use which is so frustrating so I've been trying to identify whether they're aluminium by looking at the photos which is very difficult.

Polypropylene elbows and pipes aren't suitable when connected to the horizontal aluminium pipe?

Thanks
