Horizontal flue terminals deteriated

[buffalo]

About 7 years ago, I built a small block of 4 flats and installed Sime Format 100C combi boilers in each. On a recent annual Gas Safety check the engineer pointed out that I would soon need to replace the plastic flue terminals that protrude out from the exterior wall because they had become brittle and falling to bits.
Can I obtain these on their own or will I have to purchase 4 No. flue kits just to get hold of the terminals which is what I've been told by a supplier?
Will any brand of terminal be suitable providing the flue diameter is the same?

Thanks in anticipation.....Bill

you In answer to that NO, have to use manufacturers specified flues, but having said that manufacturers of boilers tend to use the same flue providers in many cases.

only query is if you are purchasing new flues are you trying to fit them? Why dont you just let the qualified techie supply and fit and all will be well.

There's nothing wrong with the flues, it's only the terminals that need replacing.
I've engaged the same Sime engineer for years to look after these boilers and he always provides a great service, albeit he lives 120 miles away. Quite often I've obtained parts and he charges just for time and travelling expenses but on this occasion, both he and a supplier think I may have to obtain complete flue kits just to get the terminals but was hoping these may be available separately.
If they can, the engineer can replace them on his next visit........Bill

Think you will have to buy the complete flue

120 miles and you pay his time and travel! cheaper to replace boilers and use local engineer!

Call the manufacturer to find out if it is available as a separate part. Chances are you will need a whole new flue.

ive never known a manufacturer sell part of a standard flue before, and i cant see why the demand would be there to warrant such a need. If they did sell the terminal part it would probably be the same price as the standard flue and take longer to change if its rivited together etc....

so best to just buy the flue and change it.

I rang Sime and the terminals can be purchased separately at £21.00 each as opposed to £70.00 for complete kits and are fixed onto the flue by two screws.
These terminals are made of plastic and when you think of the exposure to the varying temperatures they receive over the years then it's no wonder they become brittle and need replacing........no different to a terminal at the top of a S.V.Pipe.

Thanks for the replies.

Closing this thread as you clearly have not heeded good advice and the vibe I'm getting is that you're about to murder your tenants.
