Matt,
I haven't dealt with that situation in real life, but have in theory had
several conversations about it. I am in agreement with you that this should be
allowable per the code language. You never exceed 110 s.f. and the average

It's always been my understanding that the different hazard classifications are
based upon the fuel load of a potential fire, not the likelihood that there
will be a fire. So whether there is a stove in operation or not shouldn’t
really change the hazard.
So you come back to fuel load, which is
t looking for some reassurance (or rebuke) when it
comes to ESFR.
