Hello, First Post , This week I am buying a New Buck Model 91 Cat stove (insert) I currently use an Old Buck Model 27000. Now when the Wood fuel gets low I open the top damper, crack the doors open for 2-3 seconds then open all the way and feed the new load of splits. Close the doors, pull the damper out to 4 clicks and have no more worries. What is the Technique/Requirement for a Cat stove?? I'd imagine I open the bypass, crack the door a few sec, then fully open ( Here's my blurry area ) Once I load new splits do I have to wait for it to be going good before closing the bypass? or can I load it, close the door/close the bypass and not worry any more for several hrs?? Is it like loading a Non-Cat stove or is there time I need to spend with it at each loading?? Thanks in Advance, Been Lurking/Learning and now (because of you all ) gonna bite the bullet and SAVE WOOD Thanks Again....
