Vaillant Flue Fall - With Pic

[planemad]

Dear All

Had boiler fitted today and the fall of the flue looks dramatic.

It looks like the first bend coming out of the boiler manifold dictates the fall.

Also it looks like flue angle into the manifold only just pops into the boiler terminal.

Is this install OK?

PS - forget the damage to the paint on the flue the intaller is back tomorrow to replace as his apprentice thought he would cut it to lenght on a metal pait or steps.

Flue not screwed. Possibly not cemented either. Good job he's going back. Shocking soldering to boot. A mess.

It's too steep.

Should be a 3 degrees fall. Yours may be a little more than that but its prob nothing to worry about, those scratches on the other hand, are unforgivable! Glad they're coming back to sort those for you!

Ps, he should have used that screwdriver he left behind to screw the flue

Looking at it, it looks to me that the bend dictates the fall?

Not screwed or cemented as they are back tomorrow to change it over due to damage of the paint.

Ffs, if you are not going to listen to advice, why ask.

The inner flue seal could well be strained/damaged long term.

Tell them to read the manual.

For a laugh, is that a 428 ecotec?

Thanks - I was more trying to point out that I cannot see how it could be done with less fall - how can one get around this now the boiler is fixed into position?

Close - 418

If that elbow is fully pushed in then that collar doesn't fit round, that is why they send a shorter one with a horizontal flue. If you undo that collar just enough so the foam pad starts to come away and look in the through the gap I can guarantee its not completely push in.

He has used the wrong marking on the template when drilling the whole through (that one is for the 5" flue I think).

If in doute once the boiler has been commissioned and signed off through gas safe register then you can arrange an inspection

Easiest way to get around it would have been to fit the boiler in the correct position in the first place. Shoddy work i' m afraid

Thanks Sir - do you mean the white collar with the vaillant logo on?
If so I need a shorter collar to allow the elbow to push in further onto the boiler manifold?

Did they use an existing flue hole ? Only way round it is either cut a bit more out of the bottom of the hole or lift the boiler up a bit. I'd go for the first one.

Have they got the collars mixed up (thin one for the top of boiler, thicker one for the flue) ? Could be wrong though its been a while since i fitted a vaillant. Make sure they fit the flue screws.
