Flues (AR and ID) would like to lnow what fellow gas engineers think of this grey area

[Agent K]

Horizontal and vertical flues

Existing installations no clips on extensions definitely AR? Or defect? Bit of a grey area, also self tapper screws? Ar or defect? If flue has neither but is solid would you leave on?

See GS(IU)R 27 and 28 - it is not a grey area, the regulations are very prescriptive.

If there is any leakage of Products of Combustion (POC) from the flue joints, appliance or condensate air break - it is ID

If there is no leakage of POC:

Insecure or inadequately supported flue it is AR

Incorrect jointing methods of the flue, screws missing or inappropriate lubricant used on push fittings it is AR

So if you had a terminal not 300mm from an openable window but less, but no POC was entering the property, would you class as defect or ID? Im hearing lots of opinions recently

So two parts of the GS(IU)R to consider:

Non- Compliant Terminal position is covered by regulation 27 would be AR, provided always that products of combustion (poc) are not entering the building.

The process for the Assessment of the Risks for poc to re-enter a building are set out in Gas Safe Technical Bulletin TB007.

So, the answer to your point for the terminal you described is AR. However, you would need to be satisfied and to be able to demonstrate that the requirements of TB007 had been taken into account, in making your decision, in the event of any subsequent issues.

Obviously if poc are re-entering the building, then it is ID.

Thanks for clearing that up bud
