Flue for old atmospheric boiler

[Steve jones]

HI,

I had a new gas meter fitted a year ago and the installer said he wasn't happy with the flue. I have lost the report but would like to correct any faults.
The boiler is an old Thorn floor mounted atmospheric boiler which is located in the corner of a single story flat roofed garage which is attached to 2 floor house. Above the boiler you can see the bottom of the brick chimney which runs up the side of the house to roof level.
A flexible stainless flue liner runs from the top to the bottom of the chimney and connects directly to the boiler. So from the boiler to the ceiling in the garage where it enters the chimney there is an exposed unprotected section of flue liner.
Is this allowable in the gas regs? Should there be a solid section of flue from boiler to the ceiling and if so should it be double skinned.
Thanks very much for any advice
Steve

Its so old no one can agree on how to flue it, let alone categorise it!

Speak for yourself. I know exactly how ot should be done. I also understand the "procedure", and it does not involve lying to justify condemning a boiler, a tactic often claimed to be employed.

I will say, however, that I cannot find my post immediately after the hole was brought to attention. I may have said it may cause this to be elevated from NCS to AR. I meant ID. I think that if a call was placed to Gas Safe that they would say that you cannot effectively "repair" it, although a few bands of silver tape probably would. All my NCS comments are based on the liner being sound, and the appliance passing the tests.

I have come across many flue liners in lofts, used to connect the transition block to a roof terminal. Obviously wrong, but I checked with GS (or maybe Corgi), and the advice was as expected. NCS assuming etc...

A lot of those I visited were to fit a fire, but all of those were upgraded, or the job declined.
