I know the at the air intakes below the grates are my primary controls. What is the one on the top used for? . I know that all of the air must come from below the coal so why is there one on the top?
Also Capecoaler, Yes I bought it from Barnstable stove. Doug is a really nice guy but a man of few words. He didnt really tell me much about efficiency or operation at all. He is an incredible craftsman and does an amazing job. I highly recommend him. I just wanted to know about the loss in efficiency due to its age. I know wood stoves have come a long way and are about 50% more efficient than the old ones due to lack of secondary burners or catalytic converters. I do not know if modern coal stoves employ similar technologies
You are quite welcome. I'm sure these great forum members will point you in the right direction when it comes to obtaining good quality coal. Don't overly stress out about it. There are bound to be some dealers near you that sell good coal. You just have to find them.
If I am not mistaken, your Geneva Oak is a ,"base burner," type stove. Again, there are no naturally aspirated stoves made today that can match it's performance or levels of efficiency. You should call the fellow at Barnstable Stove Shop and ask him how to operate a base burner. He should be more than happy to assist you. I'm sure he wants to have a satisfied and informed customer. Basically, base burners circulate the exhaust through a series of passages before the smoke finally exits at the stove collar. In this manner they extract most of the heat from the fire. On most of these there is a movable damper built into the stove to change the exhaust from direct vent into the longer flue path after a good draft is established.
To answer your question about the secondary air bell vent in the door-It is for use when wood or soft coal is burned. Many old timers started their anthracite fires with bituminous because the bituminous lights quickly and easily and so would light off the anthracite in no time at all. The only disadvantage to that method I guess is the bituminous will soot up your nice mica windows in the door.
