Hi all sorry for my tartiness in getting back to all. I have got to say WOW I love this furnace. The problem I had with the coal was I did not load to the top of the brick I only filled it up to half of the brick. That went out by morning. The next night. I got home from work 4:30 fire going fine from a wood fire. I started right away loading it little by little with coal. I would say probably about every 20 min. to a half an hour I would shovel a couple of scoops in the stove until I filled it completey to the top of the brick. WOW what a nice burn! It took around 150 lbs of coal. I have not had any problems with this stove only the first couple of uses. Now it works like clock work. I am currently burning only wood. I fill it in the morning and fill it when I get home at 4:30pm and then top it off just before call it quits at 11:00pm. I have no fuss no mess no frustration. This stove is A number 1 in my book.
Oh, I almost forgot. I have a 6" masonary chimney with flue. I plan this summer to change the hookup to a 7" triple wall chimney with clean out I haven't measured it yet but I think it will be approx. 30' to the top. The 7" pipe is what the furnace calls for. I have it now necked down from 7" pipe to 6" into the chimney. :)

I was keeping an eye out for you chap and hoping you'd pull through.
Was starting to get worried but glad to hear it's working well.
I don't post often and never give any technical advice but I knew you got an awesome
furnace and just had to work it out with a little help from the great members here.

Save your money on the chimney rebuild. if it is working fine with a 6" masonry chimney, your are fine, you have the best chimney for coal: a masonry chimney..

Installing a 7" SS chimney would be a waste of money. And it won't last for 50++ years like a masonry chimney will.

Get on the Manometer Loaner list and check your draft. Or spend the $30 and buy a Dwyer Mark II model 25 manometer and install it perminantly. I'll be you have .05-.09" of draft right now... you don't need more.

Hi everybody. Well I have been using my new 3500 furnace for a couple of months now and I could not be happier. It is everything I was hoping for in a wood/coal stove. I put wood in it in the morning and when I get home from work and just before going to bed. The best thing is my wood consumption is cut in half of what I was burning in the Clayton stove I was using. I guess I was doing everything I could to get head out of that thing. Well satisfied and loving it. :)
