I wouldn't consider that as a primary heat source. You will be married to the house and never be able to leave during the winter for an extended period of time. I would take that one out and get as much as you could for it. Replace it with a good used stoker boiler and enjoy a more regulated heating system.
If you are stuck on using your Burnham as a handfed the way it was originally intended, and you need parts for it such as shaker grates, there is a forum member in Towanda Pa that probly has everything you need.
