I know my stove Breckwell P2000FS is not supposed to run on the highest setting (5) for longer than a few hours. Anyone know the answers to these questions?
That is correct. If you let it run for much longer it will overheat and hit the high limit switch. Then you would need to disasseble the stove to reset the switch. Main problem when you hit the high limit, It shuts every thing down. So there is a chance you may get smoke in the house from it just shutting completely off with fuel left burning in the burnpot.
I think the biggest reason is they do not have enough convection blower capacity to properly keep the stove cool enough on the highest setting. Some stoves have the 5 setting completely removed. So your highest setting is #4.
There is also a warning about runmming higher than the 3rd setting while using the thermostat. Same reason as the 5 setting but slightly different cause. When the stat reaches the temp, The stove will automatically go to the low fan setting. T fan doesn't cool the stove quick enough to lower the temp and it hits the high limit switch and it shuts down.
My suggestion if the stove doesn't keep you warm enough and you most use the 5th setting, Is to do what I did and sell it. Then purchase a larger stove to handle your heat load.
