Sounds like a good approach.... will try that next time.Yeah, it can be tempting to close the damper early if the load really takes off. I usually set myself a timer for 8 minutes and if the flue temp starts to redline before the timer is up I will close the damper but then re open it once the flue temp drops. I find the extra time with the bypass open helps the load catch and avoid overfiring the cat.
When I reloaded, the damper was open (secondary bypassed). My point was that with that much air coming in some goes out through the secondary. Most goes out the bypass damper of course. I have lifted the griddle with the cat engaged before..... definitely has an effect!Also.. you mentioned opening the griddle with the bypass closed..? I wouldn't do that
