Flame Lift Off

[trigger123]

Hi what would i be looking for if i had flame lift off on a new installation ?

 

[stevetheplumber]

a burner

Thanks for that, like i said a new installation i was thinking low working pressure

Think High working pressure What boiler is it ??

 

[trigger123]

its just a question i have been set, i think the key to the answer is in the word NEW, im struggling with this one

 

[stevetheplumber]

to much gas or to little air

 

[jtsplumbing]

Think about what is happening ! Lifting off so need to adjust ???

Check the flue. Sounds like its starved of air

Vitiation would also cause this.

Check that the flue correctly fitted.

What appliance are we talking about here

And if it's a boiler is it premix or standard

if your gas pressures are correct then i would be looking at the flue system. Probably poc tube cut to short/disconnected.
