Now that I have choosen and ordered a stove, I'm on to the chimney... Two questions: 1. Old fireplaces always have a "flue shut off". Before you light a fire, you open the flue, when it's done and out, you close the flue, so as to not let cold air back into your house when not in use. So do we not need a "shut off" on the flue for the new EPA stoves? I don't see it mentioned anywhere, or see a part for it in the stove pipes I took a quick look at. What do you do if you not using the stove? 2. Flue temperature "probes". I see everyone seems to have a thermometer on the flue to monitor it's temp., great idea. But I read somewhere it's better to actually have a probe, that goes INTO the flue, instead of just sticking it on the pipe, so you know the actual temp of the gases exiting the flue. So what "probe" do I get, and how is this installed? Do you just drill a small hole in the flue pipe and stick it in, or is it more high tech....?
