Oil fired boiler - Flue requirements

[Newboy]

As part of a property re-furb the following issue has cropped up.


Floor mounted oil fired boiler (estimated age of about 4 years)
Flue runs off at about 45 degrees and then enters whht appears to be the base of an old chimney - clay sections.

There is an old metal inspection plate which when opened reveals the end of the flue (metal rigid) pointing into the base of the old clay flue - no physical connection between the two with a gap of about eight inches.

1) Is the boiler flue useable in this condition ?
2) If not should the flue be fully lined ?

1) Yes, it's useable.

2) Should have been lined when the boiler was changed. It's sort of ok going into clay liners, but the condensate will eventually weep through the plaster.

Was the boiler fitted by an oftec registered firm?

Thanks for the reply

Don't know about who fitted it

Spot on with the condensate - that is the exact reason that I opened up the inspection plate!

Given that the use of the clay liners is OK, would it be possible to link the metal flue section to the clay liners by using a short section of flexible liner or is the continuous flue liner a requirement?

If a full liner is required, what qualifications are needed ? (ie who do I get to fit the liner)

 

[oilman]

A liner is the easiest way to do it. You could fit it yourself with approval from building control, or fitted by an oftec registered installer.

Or you could just fit it. tut tut.

The condensate should fall to the inside of the section below it, until it falls into the boiler.

Thanks for advice - oftec it is then!
