I just finished the 3rd heat cycle @ 450 degrees for break in / paint curing purposes using a 24" box fan set backwards to draw fumes out of adjacent window, luckily no alarms went off !! The stove top fan in the LH corner is a EcoFan original 800, the stove pipe is from Heat-Fab 38" - 70" telescoping which I re-sprayed with Stove Bright # 1A54H222 which has a very nice satin sheen whereas the Heat-Fab pipes are supplied with a VERY flat looking paint (2 hours of masking and paint prep for just 2 minutes of spraying) Total flute pipe from top of stove to cap = 19 feet. Great little stove for what we want it for, very fast starting the compressed Canawick wood bricks with just 2 jumbo cotton balls pre-dipped in melted Vaseline with door ajar for about 7 minutes then close after it roars. The stored split logs shown are for esthetics only ---------- love firewood, but too old for that process anymore. Hate to say it, but can't wait for the cold weather now Thank you for all your help !
