Questions about shutter air/gas adjustments on Silver B/C's.

[Val Deale]

On a friend's Silver B that I restored, among several things, such as new 16 gauge flavor plates, new grates, igniter etc, I also installed new Weber burners. He says it's "working great, if anything it might be a little hot". Before the restoration I noticed one burner burning almost completely yellow. On his new burners I adjusted the shutters to a strong blue flame with no "floating" and maybe a little yellow tipping at times but no constant yellow tips. Here is a picture I took of the final adjustment. My question is - do the experienced restorers go for more yellow than blue on the final shutter setting than my photo? I wonder whether I should have cut the air mixture back a bit and gone for more yellow. I did state if he wanted to reduce heat he can cut one or even two burners off. What are people's thoughts on the air/gas mixture and the look of the final flame? It's also possible that my friend was just used to a grill that wasn't working with new burners and flavor bars. Do people out there who are rehabbing set mixtures for personal preferences or try to hit an "ideal" flame look? Thanks!

Looks good to me. I'd be happy with that. Here is one of mine after adjustment. I don't have a scientific method though. I'm just trying to adjust to what I feel is optimal. I don't see a way to make it too hot. If there is that's what I'd be shooting for and then just dial it back with the knobs on the control panel.

Your friend probably just isn't used to the grill working as it should, clean with all good parts. The flames you posted look pretty ideal to me. I've personally never tried to adjust the shutters on burner tubes before, they've always worked fine out of the box for me.

Thanks Steve, I looked at the flame, started to adjust the shutters back and forth and ended up at the same place as the out of the box setting so they must calibrate them at the factory. My first Weber - a Silver A had one out of back (all yellow) and I adjusted it to match the blue on the opposite burner.

Yeah, they do come preset from the factory not that I couldn't see a need to ever make an adjustment on one.

Thanks Josh, it's good to see another photo of another burner that's been adjusted. It seems to me then that you just set for the most optimum blue you can with maybe a little yellow and do all other adjusting by control panel valves and/or shutting off burners.

LOL I don't even bother especially on Weber OEM burners. I slap em in and use them.

This was one of the cheap burner sets from amazon. I just dropped them in and ran them as-they came.

These grills all came with an excellent owners manual that included a cookbook that explains the proper way to use the grill for every kind of cooking. The takeaway is that you aren't supposed to fire up all three burners to high and fill the grill with burgers or chicken thighs.
