Keystoker 70,000 Side Vents

Does anyone other than myself burn a keystoker 70k or at least know about them? The stove has side vents 10"x3" , one low one high on each side. This is a jacketed stove, double walled and I assume the vents are to let out more heat into the room. I want to know if I can safely cover the vents to send that heat into my duct system. I love the stove. Currently it's a windy 20* outside but 72* to 75* inside. While i'm on the 70k thread, can I install a domestic coil in this stove? If not I'm considering going to a 90k, because I can add the coil,but, will I like it as much as the 70k,i.e. is the 90 an improvement over the 70k. What's with the flat grate?

Does your blower blow around the sides and the top duct? if so, shouldn't be problem covering them them. I guess as long as the hot air can get out thru the the duct and not get trapped in the sides and not overheat.

On my keystoker, I blocked the front vent so all the heat goes up the 8" collar duct I put in the top. I also have the 2 front vents on my LL blocked so all the heat goes up the top vent.

What about the flat grate? do you mean it being horizontal? or the burn grate? Do you have a pic?

You can put a hot water coil in just about any stove. Depending on how far away your hot water tank is and you have install a pump and all the safety devices.

The convection blower seems not to blow through the side vents but rather the vents seem to take in and exhaust radiant heat!! My question regarding the flat grate relates to the "new" 90k I saw which has a horizontal burn grate as opposed to the sloped grate on my 70k. Is this new horizontal grate markedly better?

If the side vents are just convection, may not be good to block them off, it might get too hot. If you have a way to harness the heat or tie it into the top vent/duct, that would work.

On the burn plate, I don;t think it really matters, every stove is slightly different, but all work on the same principle. Being more horizontal, it helps keep the coal from sliding off when you trying to light it. But, I don't think makes any noticiable difference. it might just the way the stove is designed. My LL has a pretty good angle on the burn plate vs. the Keystoker being almost horizontal.

I recall digging up a patent on the flat grate Keystoker design. It's a newer patent than the one that they have for the inclined grate design. I don't recall the details of what it said, but lemme see if I can find it.

Edit: Found it - patent number 6,647,901. Also 6,588,350 and 4,662,290 relate to Keystoker stove designs.
