[Killy Bing]

Tis the gas valve, replaced but its come set up for A 28i junior.
set it as per specs for the 24i but the co is through the roo when the boilers set to minimum.

my minds boggled. High fire its fine

 

[Killy Bing]

[buckley plumb]

I hate baxi 105 gas valves a pig to set - well the one I did was

 

[Nostrum]

Set high then low, never had a problem on these before (have done alots of these gas valves)

did you replace an older style gas valve? If so did you replace the plastic elbow on the top for one without the red air adjuster behind the cap?

 

[Killy Bing]

New style. New elbow. Rid of the old ratio setting one. I've done a pair before no trouble !

 

[SafeGasInstall]

If you look on manual should tell you how many turns is for almost correct set on high an then low flame

 

[TBServices]

Or you could just ask Vern lol

 

[Killy Bing]

Nothing in manual, gas valve come with a hoe to set it up, 2. 5 to 2.75 turns from home. Still nothing

 

[Killy Bing]

Sorted guys. Piece of paper was useless. After much playing about i got the numbers right.
thanks guys!!

 

[Nostrum]

Got your adjustment screws the wrong way round then? Hah

Not at all! High set as per the data sheet.
low however was over two turns off.
badly machined i think.

 

[Killy Bing]

Yes i did set them, with the fga in.
High set with the correct turns and fell into the correct co2
high however was two turns off what the data sheet supplied said.

 

[Nostrum]

Thought it was min that was out? 🙂

 

[Killy Bing]

Damnit. High was fine.
low was two turns out from what the sheet said 🙂

The data sheet on these are just ballpark figures to get it firing, you always have to play about with them with the FGA in to set up correctly.
