You should easily get 10 hrs of burn time I've gotten as much as 15 hrs before . Whatever your doing I'd go back to the drawing board and be sure your wood is dry and well seasoned that in itself makes a huge difference in burn times
do you have the cold air return kit?You should easily get 10 hrs of burn time I've gotten as much as 15 hrs before . Whatever your doing I'd go back to the drawing board and be sure your wood is dry and well seasoned that in itself makes a huge difference in burn times
How many full cords do you guys burn I understand the variables and its still a new furnace just kind of looking for guessstmits im trying to get ahead so I can have well seasoned wood I have about 5 fulls cords cut and stacked
with it shut it runs -.04 to -.06 with open it was -.06 to -.09 I know the book says not to go over -.08 but I wouldn't think that little bit would make a huge difference. Where exactly do you measure it at? I tried two different places about 6 inches out the back and I tried it again about a foot or so away. The readings were lower closer to the back of the furnace.Either/both. If you have a baro, it will keep draft the same no matter the damper position. Just make sure you run 'er hard for a few minutes before you test, to make sure the chimney is fully warmed up.
A high draft speed will send the heat right up your flue this is more critical on these type furnaces because they rely on the natural draft principle to get all their air from the intake flap . Not enough and it smolders with creosote buildup... too much draft and it flares up and sends your heat right out the flue with short burn times[/quote
I'm pretty sure I'm right within draft specs. That's why I was wondering where to actually test the draft at. Because if its the lower part im right on and if it is up higher im at -.09 which is barely over the -.08 max
Did you buy the Tundra? Thanks though I talked with the sbi tech and he had me switch my thermostat to a different one that has a swing setting and he had me set it to 2 degree swing now I'm back to a full 10 hour burn. He said that sometimes people have issues with burn times on the thermostats that run on cycles per hour.Mine sits on a pallet in the basement so im not much help but I would say somethimg is wrong possibly to much air i would think the secondarys. Should be fireing strong and should still be in log form
let me know how it is replacing that. i still cant get my burn tubes out.For anyone who is looking into buying a tundra, SBI is very helpful if you have any questions they will call or email you. Also for some reason my vermiculite baffle cracked in half and they are sending me a new one and a couple firebricks that were broken when I received it. If you ask me their service and support is great.
