Thanks for an informative thread on the rebuild. I inherited the same 2462 stove with the house. This is my first year and I'm still getting used to it. I'll make sure to check the inner top plate for warping next time I have it opened up.
My stove is also in the basement like yours. Are you able to heat the upper floors of your house with this stove? It looks like your basement is unfinished. My basement is only 640 square feet, finished, and I find that running to stove got enough to keep the cat active overheats the basement and very little heat makes it up the staircase. Can you tell me about the fan you have installed? Does it just circulate heat throughout the basement?
I have a rancher, 1200sq with full basement. Total 2400 for heating. Yes it will heat the whole thing, but it is MUCH warmer around the stove. The basement is unfinished, but we use it as living space ( workshop- where the stove is, office, laundry, bathroom. Most of it is fairly open so I can blow a pedestal fan out of the shop area to heat the basement more evenly. I'm sure a fair amount comes up the open stairway or transfers through the floors. I also use the air handler for my heat pump to circulate stove air. Kitchen is right above the stove so that floor is always toasty. Bedrooms are farthest away, which is good they dont get the direct blast or it would be too hot to sleep.
I believe the redesigned top started in '97. Mine is a '94.
The fan pictured is what is designed to be on it. Mine was on when I got it. I think you can still buy the kit ( I have seen them on eBay. Comes with two plates to block the convection inlets on the bottom, but they would be easy enough to make if you just found the fan. It pulls air in the back and blows it out the from top through the opening with the brass rod across it. Definitely puts out a lot more usable heat with the fan on. This stove is only rated at 55,000 btu but 2400sq ft. I notice there are much higher btu rated stoves at significantly less area. I don't know if that is just diff rating, or is it that much more effective? Also dont know how the blower plays into the rating. I need to browse around the site here and see if anyone has addressed this...
