terminal question

[yo1]

any ideas on what a room sealed boiler that has no terminal fitted onto a vertical flue would be classified as.. came across one and the inner metal pipe had corroded a bit which connected onto to the terminal and caused it to come off the flue. i disconnected the boiler as I concluded it would be id.

Not sure about ID as it's a room sealed appliance, where is the danger?

 

[Boilerbud]

Boiler will probably fail flue gas analysis (sucking in products of combustion) and will therefore be id but even if it should still pass fga it will at least be classed as at risk so customer cannot use it until flue corrected. My opinion but lets see what others say.

Cheers

i'm surprised it worked,surly at risk..?

You'd have to fga it I'd say to determine best criteria to attach. Certainly an AR ... Any immediate danger to life or property? For me that determines the crossover from AR to ID personally

flue pipes were flush with each other and also think rain could go down the flue, more possibly at risk

 

[kirkgas]

a test or tests are needed to determine ID or AR, if something is blocking the flue then ID, if something could block the flue then AR

only if it rains so by using the word "could" you are answering your own question so its AR

If it's a room sealed appliance then what is the 'risk' if the flue terminal is faulty outside of the building and no POC's can enter the building?

 

[Mike Jackson]

I'd say AR due to incomplete flue but FGA could confirm it as ID due to recirculation of flue gasses causing poor combustion.

the risk is the air intake getting blocked which could lead to incomplete combustion which if the combustion chamber and/or flue isnt complete could lead to poor POC's leaking into the building so therefore AR

Definitely At Risk. I came across one a while ago, a builder had moved a worcester flue and converted it to vertical. Popping out the roof was just the end of a 1m flue extension and then the elbow from the end of a plume kit poked into the inner flue. I took a couple pictures I will see if I can find them.
