Have an accentra free-standing, that will be a corner installation. Still stewing over the vent install. I was thinking, if I go straight out through the wall, it must be kind of difficult to disconnect the pipe for cleaning. I've read where you should disconnect things so that you can remove/inspect/clean the exhaust temp probe, which is right there in the exhaust outlet. But what I'm wondering is, how can that pipe be disconnected, after its initial install, when everything is siliconed-up, glued into the thimble, and pipe sections stuck together...and outside, the rest of the pipe is secured to the wall, etc, etc. it ain't gonna move. So...you must have to pull the stove away from the pipe. (?) it weighs 350 lbs. Its hard to move when its sitting up on a furniture dolly. how the heck am I gonna pull it off the pipe? (and even worse: how am I gonna get it back on?) Up, then out...I can see how a long length of vertical pipe is going to be able to flex more, and be more easily detachable from the back of the stove. But it may require that the stove sit further away from the walls...its a small house, and I really don't want it sticking way out into the room. otoh...its gotta be cleaned, and access to the rear is required. So maybe I need to be able to pull the stove out in either case. ( I've seen posted that some have used those furniture-moving thingies that make heavy things slide easily. maybe I should have the stove sit on those. they wouldn't be visible, with this stove). up...then out: in case I ever need to replace the stove, the next one most likely won't have the same vent location, but the up-out pipe can be easily changed. If you go straight out...this could be a big problem. wife doesn't like the "up--out stovepipe" look. she'd prefer straight out. cleaning the pipe/tee would be easier if it were outside. thoughts?
