What considerations are there for venting up and out vs out and up? I have seen lots of mention of up and out, but not so much for out and up.

  • I would think it is just athletics: do you want the stove pipe visible on the inside of the house or the outside?
  • There was some talk of heat recovery for up and out, but I’m skeptical.
  • I also saw talk of it being easier to replace a stove that is vented up and out because you can buy an elbow joint to line up the vent to the stove.
In this case the vent is on the 1.5 or second level. So out and up would mean I would need to get on a ladder to access the clean out T.

Power has gone out twice since we moved to the area. We have a generator but this stove will be burning 24/7 and if there is an outage at night I imagine our living room will fill with smoke that will cause mild damage. So I’m not too sure if I want to do straight out, even though it seems cheapest and easiest.

Thoughts?
 
The biggest problem with out then up is if you ever change stoves it makes things more difficult because of exhaust height. Had to change mine 3 times now. The nice thing about out then up is that it puts the clean out t outside so it keeps the dirt outside when cleaning the exhaust. Really it's just a matter of preference or what will work best for your install.
 
If you want the T low to make it easier to clean then that's what you should do. If you go the other way you'll just get frustrated everytime you get that ladder out.

As far as the power going out and filling the house with smoke, you should get a small UPS backup. The one I bought is a recommended one from Harmen and basically only runs the exhaust fan, not the entire stove. It's about 12" x 6" x 4" so fairly small but will keep the house from filling up with smoke if we're gone or sleeping. It was around $75 off Amazon.

Which model is that? I don't think my stove has an exhaust fan only mode. The UPSs I've seen run ~200-300watts for minutes or a couple hours, not 4 or 6 hours. If power goes out at 1am I don't think it would last me the night until I wake up at 7am. Unless I'm missing something.
 
I have the TrippLite internet750u. It won't run a couple hours but the output when on battery is a PWM sinewave output or "modified" as some call it. My Harmen senses the different input and will go to exhaust mode only until power is restored. I haven't timed it but I shut the breaker off to simulate a power outage and it was able to exhaust the smoke until the fire was completely out.

I had my clean out T put inside the house. That's what I meant about the ladder. It's at about a 45 degree angle, then hits a 90 and goes outside.
