Flue gas analysis books??

[handybadger]

hi can any body reccomend Any books expalinig what the results from the flue gas analyser actually mean.
i have recently done my cpa1 and when servicing find that sometimes co2 levels can be out by 0.1 or 0.2 and just wondered if this is enough to be worth while adjusting the gas valve.

I have loked online and noticed that corgi do a few books are these any good?

if you need a co2 of 9.1% +/- 0.5 the readings can be 8.6-9.6 simples, but I prefer to hit the 9.1 personally. whats wrong with your cpa1 course notes?

As above look at what the maufacturers instructions for the appliance recommend and adjust the gas valve to suit.
