I do Hvac research stuff for a living . This looks good to me , see my response to the other comment for more detail if you want .

What kind of heating equipment is it ? <| sep |> How is he not on an international warrent yet ? <| sep |> I would have to say so , because I nearly said Faygo and had a mentaldebate before responding the first time . Maybe while eating some BetterMade chips ? or is that just a SE MI thing ?
