Screws in flues

[AWheating]

You could argue that the flue is incomplete and therefore AR. Should be academic though as anyone worth there salt will have some self tappers on board and sort it. It does annoy me when a flue is supplied with screws and they are not used. What did the guy think the little packets of screws were for?

I IDed one a couple of years back a Worcester with no screws, not enough supports and too long. The equivalent length exceeded Worcesters maximum and when I touched the flue above the boiler it fell off.

you could argue a gas cooker without a chain is incomplete and so on and so on. i agree with you about the screws, I think common sense is needed and lets be honest its quicker to put a few screws in than fill out a warning notice.

Surely adding a screw to a flue that doesnt come with screws and isnt asked for in mis means youve now modified the flue from makers specificatication
i thought modfied flues were automaticly at risk

or is it engineer improvement rather than modification? i guess if you wanted to you could phone and ask the manufacturers permission.

Adding a self taper is hardly modifying a flue, you boys must struggle getting those vertical flues out straight using those metre long sections, after all cutting it down is a modification?

I carry a little tub of short self tappers, with a big flat head (wish I had a photo handy).

If they look like they could do with a screw or do, I'll buzz one in. Takes seconds!

I came across one today, ideal isar. No screws in horizontal elbow, flue not sealed externally or internally. You could have just pulled the flue out from outside! Cemented up outside, bit of foam internally and a screw in the flue job done 10 mins.

That's em. Exactly them!!

I've had my tub for so many years I can't remember where I bought em. Thanks!

If its a vertical i rivet them. 3 rivets per joint and it ain't going anywhere.

Riveting!!

Sorry I couldn't help myself.

Good idea actually. I've carried a riveting gun and rivets for years, and have only ever used em to repair my mates 'hop up'.
