Hi everyone. So I've gotten majority of my questions answered now and even found a source of clay dirt or I get to build my RMH with cob now and not concrete. There is still one thing that I realized I don't have full clarity on and that's the clean outs. I know where to put them, I know how to tie them in. What I don't know is how to cap them off so none of the gases from inside get out into my living room. Also since these are metal would the cap get hot to the point that it could burn someone if they touch it?
Mark K. : Recent tests with metering units at the' innovators gather' at Wheaton Labs show very low Carbon Monoxide levels, this is probably because CO is a
Fitting caps just are not a common problem, though looking to make sure all caps are on snuggly if a working RMH starts to be a little sulky to start, or smoke
back is a good place to check mostly because it is so easy to check !
Ernie Wisner speaks about monkey fingers that will find and play with an RMHs clean out caps ! It would be a good idea to check these places, after you
'have company over' especially where the host and hostess can often be distracted! The very 1st clean out cap may be rather warm, or not, depending on the
way(s) the manifold/transitional zone is constructed !
Hiding the caps behind various trim pieces is a good idea, but mostly to protect against 'monkey fingers' For the good of the Crafts ! Big AL

Mark; I poured castable refractory into my cleanout cap. The first time I lit the dragon I just had a bare metal cap and YES it got very hot. After adding the refractory it still gets hot but not sear your skin hot!!
I was wondering the same, but as all my cleanouts are on 'T' pieces, there's a good couple of inches behind each one where a disc of rockwool board will fit without interfering with the airflow. I figured on threading a little loop of wire through each so that they can be pulled out easily. Judging by the feel of the caps, temperatures will be well within the limits of the rockwool, and it should be enough to prevent the caps getting too hot.
