New to the forum. I’ve been burning for 15 or so years on a baker wood stove with two front double doors and air adjustment knobs. It has a brink bottom with no grates or ash pan. I recently picked up an Englander WHI-2052 wood furnace that has the brick lined grates, lower ash pan, and blower. I installed this in my garage with 6†pipe up through the roof. When I fire it up, I’m leaving the bottom ash door open for a bit to get air to the fire. After about 20 minutes or so, the blower finally kicks on at 150deg. Once the blower kicks on, it cools the unit down, a lot of times below the shut off that is set at 90deg. I’ll leave the bottom door open another 15 min or so to get the fire going then I close the door. The ash door has one air vent, that I have all the way open. The fill door has two vents that I leave all the way open. If I leave it run like this, it never continues to burn hot enough to keep the blower from cycling. The wood is good as I burn it with no problem in the house. Last night I popped the top cap off my class A to help increase draw and that didn’t seem to help either. I just don’t know what I’m doing wrong using this burner. Why can’t I keep it hot enough for the blower to stay on. If I leave the bottom ash door open it will run at a steady ~120-130 deg and the blower goes. If I close it up which is how it is supposed to be for safety, my temperature drops. I can never get a real good coal bed when I leave the bottom ash door open and never get it hot when the ash door is closed. Coming out the back of the stove, I have a 6†black tee with a 1’ cleanout drop. The black goes 4’ vertical with a dampener around 2’. At 4 foot, I have a 45deg bend 2’ of black another 45 bed (jog in the stack) then 2.5’ of black going into my class A up through my rafters and roof. The Class A is approximately 5’ above where it punches through the roof and is 2’ above the roof at 10 feet away but not above the ridge. Does anyone have any suggestions as to what the deal is?
