What is considered to hot for single wall pipe?

[lopiliberty]

I was just reading a post where someone damaged there Class A stove pipe because they where running to hot. When I reload I take my stove pipe between 450 and 500 sometimes alittle over 500 for 2 to 3 minutes to burn out what little stuff built up from the last load. In the morning I let it run that high for a little longer. Could I be possibly doing damage to my Class A pipe that is 18 years old? As I type this just reloaded the stove and what a firestorm and pipe is at 450.

I do not know the limit but I do know that I have never liked that idea of burning hot in order to clean out the flue or chimney. Sorry but the only answer to cleaning out a flue is to burn good fuel so your flue does not get gunked up.

At 500F surface on single wall, you should be well below the continuos limits for class A pipe. FWIW, I also let my stove go up to this temp once a day.

fwiw, we do it regularly (from 400-500) but it is the temperature where we engage the catalyst.
