Recently replaced a Carlin G3B with their EZ Gas Pro to fire a Vega boiler (which is nearly identical to a Biasi) with baffles. Wondering how these numbers look?

My mistake. I thought it posted in the original post.0 -
Not bad, at first glance. When you were testing, did you reduce the air supply until the CO started going up?All Steamed Up, Inc.

Out of the box from biasi, it was around 6% O2 and 8% CO2. Once the boiler was warm, I started to close the air band until I reached the above numbers. Thinking the O2 can be reduced a little more. Excess air seems a little high. Trying to find a happy place for it to run as it is located about 3 hours from civilization and we are away during the week.0

You don't want to reduce the air too much. Always leave some headroom in case the fuel or air supply varies. The boiler will soot up if the air/fuel mix gets too rich.
At this level of excess air, rising CO indicates the mixture is getting too rich. Add some air and see if you can get the CO down below 50 ppm air-free.All Steamed Up, Inc.

Agree with @Steamhead
CO is supposed to be under 100 is safe under 50 is what you should get.
If anything you need a touch more air not less.
Watch the CO and Co2#s while adjusting..1 -
Much appreciate the comments and feedback. Sadly the company who installed and got it running with the biasi configuration (subsequently would not change the settings) will not be able to get back until spring as their company will not allow me to fly them in. So I purchased my own Testo 320 as a tool to help me learn about this.
Next time I am up there I will try increasing the air. It is slightly under fired so there is room to increase the fuel too. What are your thoughts on going up a size? Currently at 80,000 btu and the boiler can take 110btu.0 -
You're not that far off. I wouldn't do anything drastic. Just see if a little adjustment will bring the CO down. With the #s you have I would like to see the Co drop a little.
Make sure the boiler is hot when testing a cold boiler will make more CO, Just like a pot of water on a gas stove does.0 -

You are over fired. You need more air or less fuel. Ideally 6% on O2 is the target0
