flue gas analysis

We all make mistakes from time to time, god knows I've made a fair few!

OFTEC figure I was given is not to allow C0 go above 90, preferred C0 figure to aim for is below 50 on condensing boilers.

As far as I know they are using BS 7967 I don't see the actual figure of 90 ppm in the OFTEC manual I remember from the OFTEC course.

Just to add something to this.
A maximum 200ppm CO is a limit BG work by.
Worcester also state this limit for their boilers.

 

[Dotty]

And Veissmann quote 100ppm, Lochinvar quote 100ppm.......

MI's are king!
