white part of flue on show

[buckley plumb]

what are folks views on some of the flue showing - I know glowworm allow 600mm to potrude from wall and Worcester now allow theirs to be run externaly but baxi say non to be on show. gas safe don't approve of it

 

[Killy Bing]

Makes you wonder as its all from the same factory basicly....

 

[AWheating]

all depends on the manufacturers instructions and if that part of the flue is UV rated. Dont listen to gas safe, if the MI state its ok then its ok.

Spoke to vaillant recently to query this, they are happy for their flue to be run externaly but you must silicone any joints to stop water getting in the air intake. Dont fancy it myself but to instructions so is ok.

 

[buckley plumb]

Worcester say the same called them

 

[lame plumber]

intergas say no no no

 

[AWheating]

and churchhill says......... oh yes

 

[Roger Welton]

intergas say no no no

They've change their minds again now.

I had x2 main eco I fitted picked up on inspection yesterday. I was just passed guttering main say yes

 

[beesley121]

I wouldn't, for one it would look terrible. For 2, everyone knows silicone don't last forever.

 

[buckley plumb]

baxi said no unless under eaves but better to not

Really, who cares.

Really, who cares.

The customer will care when their brand new boiler is wrecked with water damage cos the flues not sealed properly

 

[Ermintrude]

Worcester actually show it in their books.

Are we talking about a join showing or 1 inch of white flue on show outside

if your talking about the later then half the contries boilers are knackered and i bet 90% of installers on here have at some time had a bit showing

 

[buckley plumb]

an inch or more . baxi say non should be on show unless under eaves. like the poor examples on here I know there is a hole around the flue and its near a window and the other is near a vented eaves and extending it is still not acceptable just examples and seen them this long under circumstances

 

[Ermintrude]

Did u just fit that valliant/snow perm?

 

[novicegas]

Vaillant instructions say the tip of the flue should be 83mm to the external wall in order to fit in the collar. Easy for a technical advisor to say its fine when the MI's don't

 

[Ermintrude]

Valliant also show a hacksaw cutting flue.... For those of us who have actually done it it's more like hacksaw deforming the foil and cutting plastic inner!!

So what do you cut your flues with if not a hacksaw?

Lol, looks like a bottle opener to me

 

[tamz]

Its a tin opener :wink:

 

[Ermintrude]

I like to use my lazer eyes or sonic blaster. Or a 2mm grinder blade m&g flues are awful.

 

[stratplus]

I'll be sticking to my hacksaw then
