<div dir="ltr"><div>Hi Paul; </div><div><br></div><div>I stand corrected. This is what you said to me a week or so ago. You were suggesting a dynamic change. I have been running static batch runs, and that colored my thinking.</div><div><br></div><div>Paul Anderson: "About height, whether of riser or of chimney: I recommend some simple experiments when your unit is running. Have some different lengths of extensions that can be easily placed (not even attached) on top of the current unit. The additional draft will pull more secondary air and make the flame be LOWER as long as there is control over the entry of primary air. But if the primary air is free flowing, the primary air will eventually "catch up" with the increased draft, and the flame will become higher than before. If that is not what you observe, please let me know so I can adjust my thinking."</div><div><br></div><div>I will have to give that a go.</div><div><br></div><div><br clear="all"></div><div>Regards,</div><div>Julien</div><div><br>-- <br></div><div class="gmail_signature"><div dir="ltr">Julien Winter<br>Cobourg, ON, CANADA<br></div></div>
