Hello all. I recently built and as of lest weekend am now running my second
RMH. I have found, as most have, that cold start can be challenging. On my second build, I have incorporated a 1" iron pipe running into my chimney cleanout and then up my chimney to just under where the horizontal pipe from the stove enters the chimney. On this pipe I have mounted with a air
mattress fan that, at the flip of the switch, blows a small fast stream of air up the chimney causing a venturi effect and drawing from the
RMH. Once fire is started, up to a minute or so, the pipes are filled with warm air and the pump is turned off. Since there is no creosote anymore, I don't see any future problems. If this picture thing works you can see where the pipe enters the clean-out in the wall. The clean-out is sealed also so no leaking. I hope this can help someone.
Thanks,
Brad
