Balanced flue gas fire

[Backboiler]

Is it normal to check the POC on a fire with a balanced flue and decorative flame effect, with the flame effect tap switched on or off?

I wouldn't FGA an RS appliance unless the MI's stated so.

Agreed but the appliance is in my house and I was curious when servicing it yesterday. Combustion was excellent without the decorative effect tap open but FGA went ballistic when I turned the tap on!

It will do its altering the way it burns to give it a real flame look

Correct it adds shed loads of secondary air it make the flames yellow, floppy and more realistic, hence the carbon (soot from the incomplete combustion) don't do it again or you may poison your O2 cell in you FGA, if not pulled out quick enough

to create the "good looking" flame picture the appliance will burn poorly,badly,incomplete to some degree (or however you want to term it), unless the manufactures instructions require the test then i would avoid doing such tests.

what readings did you get?

 

[zeebeedee]

Probably about 3000ppm

 

[AWheating]

watch you dont screw your analyser up with those readings, you can kill the cells with high readings, dont know at what level tho.

 

[Backboiler]

Yeah thanks for the warning but I did pull the probe quick. It's set to alarm when it exceeds 300ppm so I pulled it at that.

I would sack that idea mate . Not worth the new cells lol

Would be cheeper to buy a new FGA.
