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.
 
I don't think it's a good idea to engage the cat right away especially if its in the inactive zone. You should keep it in the bypass for at least 10 minutes to drive off moisture in the wood and heat up the chimney to maintain a good draft. If you have really good dry wood it probably wouldn't hurt to do this in a pinch or if your in a hurry but I think it may hurt the cat in the long run.
 
Your cat goes inactive?

I've been burning 24/7 for 7 days and the cat hasn't gone inactive once, even with just coals.

But I generally let a new load burn for 5-15 mins before closing the bypass.
 
I'm not as seasoned as these guys but for preserving the cat I only engage the cat when the probe indicates well into the active zone, I go for that first tick above the active line.
 
I always burn it with the bypass open until the probe is active, if I load when it's already active I still burn it with the bypass open for 10 minutes or so to drive the moisture out just like Todd stated.

I would agree with Todd but that said if the wood is seasoned well and dry..not wet from rain or snow covered you probably won't hurt the cat.
I do it now and then.
If you haven't done it just lift the cover off that's in front of the cat and take a peak in there with a flash light and see if it is clean.
You might be getting more fly ash doing it the way you are saying.

Of course do it with a cold stove...lol.
 
It also doesn't hurt to burn it hot for a bit to burn off some of the dirty glass and any deposits left on the cat. If I'm in a hurry to go somewhere I wouldn't hesitate to throw the wood in and engage right away because I know my firewood is primo and I also know the t-stat should open up to get things going if it wants to stall.
