I'm installing new firebrick and reinstalling the baffle s bar in my lopi answer stove. The manual doesn't show how the bar gets reinstalled, and it had fallen out when I was moving the stove. I'm uncertain how to reinstall it. Other Lopi models have a more descriptive manual, but do not match the Answer configuration. I see some marks on the bar that suggest it sat on one of the air tubes or quite close to it, but I'd rather not restrict the flow of air within the box! Can anybody show me there setup? Thanks!
