weil-mclain soot build up

but I'd also check the orifice sizes and the BTU content of the gas being used. Also, if this is not a sealed-combustion boiler, is the vent termination facing the prevailing winds?

Do you mean CGI
How old is the boiler it is possible you are set up for natural but you would most likely have other issues than just sooting (like flash on ignition).
If room is tight could bee poor air supply. Power venter could also be not performing properly. Vent run could also be to long or wrong size pipe. Could be issue with the gas logs.
Did they run out of or low on propane before the problem occurred.
You have 13" on inlet side of gas valve what is the outlet side like.
If the boiler is otherwise in good shape clean it up start it and do a complete combustion analysis co, o2, co2, draft gas pressures on both sides of the gas valve.
Put it all together then check with Weil Tech.
