After reading the posts in here about dust ruining these catalytic heaters... I got to thinking. I have a Coleman camp propane heater and it probably has dust on it! So, I just dug it out and hooked it up and, although it was slow to start, it start up with a flash and got really hot really fast, just as it usually does. As soon as it cools down, I will be double bagging this thing and putting it in my camper away from cat and dog dander (well, lesser degree out there). <br /><br />Thanks for all the debate and thought provoking commentary here. I learn something new every day!<br /><br />Carpe the hell outta this Diem!<br />Bodhi
