Just to be clear ... the boiler fires, quits, fires, etc. for a minute
or two before it quits, but then does so again on the next (pardon my
nomenclature) "call for heat" (?) from the thermostat ... there is a
correlation between the "click" of the stat and the boiler firing.
However, the temp is near the therm temp, so I don't know if this is
"normal" or not, since the water would only need to be minimally
heated to remain at temp, but this is the first time that the smell is
present.
