Hello,
I recently moved into a house that has a coal stove. They are not too common in the Philadelphia area so I'm trying to learn as much as I can to use it safely. It is an Alaska stove Channing III model that uses anthracite rice coal. I started it up last week and it is working great but I want to understand a few things better.
- This model has an "Auto Heat Control Box" numbered 1-5. The manual simply says that as you turn the number up the fire will get bigger and output more heat. I am curious to exactly what it does though. When I turn this up is it increasing the coal feed rate or increasing the air feed (or both)?
- There is a thermometer on the flue and it reads between 150-200 F when I have the heat box set to 1.5-2 setting (temperature goes up when the blower is off and down when it is on). The thermometer has a note that says "too cool" next to temps under about 180 F. Do I need to keep the temperature above a certain point? I am assuming that this maybe just applies to wood burning stoves due to wood not burning hot enough and producing creosote?
- What is the proper cleaning procedure? The previous owner told me he takes a shop vac and vacuums the inside of the stove and then removes the barometric damper flap and just vacuums the elbow below it in the flue. Is that all that is required?
- I have 2 carbon monoxide detectors. Where is the best location to install them relative to the stove? Is there anything that I need to avoid that could cause CO contamination (burning at too low of a temp)?
Any assistance would be greatly appreciated!!
