Re: Down draft stoves are grate!

["Ron Larson" <ronallarson@qwest.net>]

Tom
    You didn't catch the distinction I was making between DD and IDD (or
UD).  To the best of my knowledge all of your turbo stove work has been with
IDD (UD).  Please advise whether you have done any DD stove work (not DD
gasifiers) or know anyone who has done DD stove work with air control (not
fuel level control).   Either forced or natural down draft.   Thanks.

Ron
