This is my second year burning my King Ultra,and I think I'm doing pretty well at it,but here's a question I pose to the veterans.When I'm near the end of let's say a 12 hour burn stovetop abot 300,coals,but cat is in the inactive zone according to probe.Can you just open the bypass a minute or so reload,close bypass and let it do its thing,or do you have to keep bypass open until cat goes active again.I have just reloaded and she fires up on her own and cat engages when it heats up,I do nothing with the tstat the amazing thing is 15 minutes later the cats red hot,and my house temps never fluctuate unles I dial the tstat in higher.Example,last night fired her up at 6pm,larch wood,setting on #1.75 about,house went to 73,this morning at 8am house still 73,stovetop 350,cat at about 200 ,opened bypass threw in 4 splits closed bypass 11:30 am house still 73 and my guess will stay that temp till about 6pm tonite.The cat goes in the active zone in about 15 minutes for another extended burn.
