I'm going to start with my chimney and going to drop a ss liner down it. My question is since my chimney is in the middle of my home and receives heat from the house except for maybe 12', should I insulate the liner or not. Chimney total length approximately 30'. thanks for your input
I have one of the first couple hundred Tundra's made. A couple weeks back I was at Menards and noticed on the new Tundra's the damper door was redesigned.
I'm not sure why they changed it. I honestly don't remember if the one at Menards was cracked open, but I know it did have the shiny insert. I just installed it so I'm not sure if their is any performance change yet.Interesting--I have a recent Tundra (June 2014, post ash-drawer) yet it doesn't have the shiny metal insert that you show in your last two pictures. Any word why the change?
Do you happen to recall if the unit you saw at Menards also had the damper cracked open? I was down their aisle recently and don't recall seeing the damper cracked open.
Edit: On second thought, maybe the shiny part is only needed for retro kits, and newer furnaces are inherently designed with whatever air holes are needed.
Do you notice a difference in your furnace performance now?
My tundra is in the basement so the only place you can hear it in my house is in the kitchen because there is an old air return grate in the floor there. My kids are used to noise though. We can crank our TV up and it doesn't bother them.Thanks guys, makes sense. Then the 0.20" spec in the manual must be SBI helping us get equal flow out of our supply registers, and have nothing to do with removing heat from the furnace. I suspect that because otherwise the manual would have a max allowable pressure across the blower. If the manual says it's ok to operate at low speed with 0.20" in the supply plenum, then I can only have more total airflow if my entire pressure drop (with lighter filter) in the system is less than that. And I'm more interested in adequately removing heat from the furnace than in equal flow out of all registers. House is warm, no fuel bills, wife is happy, I'm happy...
I did put aluminum tape to connect the blower discharge to the housing, and on a couple other places that were leaking air. I can still feel air leaking in a few places, but nothing too much.
Last weekend for fun in the middle of a small fire I cut power and pulled the filter for 1/2 hour. I was impressed by the air volume pushing out the registers, and the air wasn't too hot. That's important to me, so I was pleased.
When the HVAC guy replaced my oil with LP furnace, he had measured a 0.34" total gain across the blower (cold return to supply plenum) and had said nowadays they shoot for 0.20". I also thought I had read the same a few places, so that is what I was shooting for. Maybe I was mistaken, and it is supposed to be a 0.20" goal for the supply plenum only. Since then the HVAC guy has been wrong more than once too.
Another question: how loud would you describe your system? Mine is loud enough that we couldn't keep the TV super quiet if the kids were sleeping, without missing quiet dialog some of the time. That example is part of the reason I went to low speed, that helped reduce noise a little bit. I'd like to make it even quieter if I can.
SBI doesn't offer one that I know of. I suppose you could cob an aftermarket coil in if you were determined...Ok, I just found out in another thread that a hot water coil is an option for the Kuuma (thought I had been told otherwise). Any one know if it is an option for the Tundra? Thanks
Need additional input about the noise level from the unit. I am considering getting a unit to put in an unfinished basement however the basement will be finished off and someone will be living there. Is the noise level too loud for someone to be occupying the same area?My tundra is in the basement so the only place you can hear it in my house is in the kitchen because there is an old air return grate in the floor there.

I'd say no. I frequently talk on my phone when I'm in the basement and have no issues hearing the caller on the other end when the blower is going.Need additional input about the noise level from the unit.

Hope I didn't cause undue alarm. I'd say my Tundra is a bit quieter than the new high efficiency LP furnace they installed last fall, 90,000 Btu/hr. (Which, however, isn't as quiet as I was expecting). I'd also say the Tundra is quieter than the oil furnace I had taken out.
I would say no. It is just that there are a ton more of them out there and they are marketed toward the DIY crowd so you just hear more about the issues. The Kuuma guys are talking with Kuuma over the phone to sort out their issues.Thanks for the input guys. Other question is it seems like the Tundra takes a lot more tweaking to get it set up right compared to the Kuuma. Is this correct?
