Miller gun furnace -- how to adjust air mix

Thanks. I've been keeping this old burner going for almost 30 years. Moved it once, moved and replaced the fuel line several times. Replaced nozzles, adjusted ignitors, etc. Thing just hums along, but I feel a need to do something more precise as you suggest, and also to a general safety check, firebox, etc.. The very few times I have had a pro come in, not a one of them ever used an analyzer. One of them told me just look in the peep hole and adjust so that top of flame just flicks into sight. So I should call to have someone come specifically for that purpose -- i.e., analyze combustion. Anything else I missed?

Thanks much.

Nowadays, with fuel being so expensive, don't you want to get the most heat for each dollars spent?

Get someone out that know how to do it right with an electronic analyzer.

Will do. Thanks guys.

Hi Dennis, hope you are having a nice day

This is not something that should be attempted without the proper tools. it takes a combustion analyzer to properly set up a burner.
