Harman Magnum Stoker

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

IDLE Mode, NOT burning hot. That is when you will have the LEAST draft for setting up your baro, you don't want to go below that setting. When it runs hot, you will get more draft.

MOST chimney Draft doens't go over approx. 0.10" Most setting for most stoves are in the range of 0.02 to 0.08+ Inches of Water.

Most of the people on here are using the Dwyer Mark II model 25, which goes from -.05 to 3.0" Inches of water.

So, probably this +0.10 to 0 to –0.14" W range would be the closest you would need. 13-3000
