Harman Stove Company Harman Stove The Harman Magnum Stoker manual Restricter Plate

Fine Tuning Draft

With fire burning and stablized take draft reading in flue pipe and note the reading. Next take a reading in the fire box by removing the bolt in the front center of the unit.

While watching the draft meter, close the restricter plate on the combus- tion blower slowly, until the needle reads about the same as it did on the flue. An example would be a flue read- ing of .05 and a firebox reading of .02. Close the restricter plate until the firebox reading is .04 to.05. Closing the restricter plate will reduce the positive pressure from the blower and increase the negative pressure in the firebox.

WARNING!

If draft is at .00, carbon monoxide will escape into the room. Too much carbon monoxide can kill you.
