Hello all, I just recently went to a horizontal exhaust. I really don't care for ladders that much and my 25ft vertical exhaust was becoming a challenge to clean. Now with it going straight out the back, 2ft double wall connected to an elbow that connects to the stove, I can clean it at will with no problem. Thinking about getting another 1ft piece to extend it farther from house. Right now it's about 14in from houseFrom a vertical to a horizontal

Your owner's manual will tell you what the MINIMUM distance from the house to the cap needs to be.
You must also consider the proximity bushes, trees or leaf piles, as they may be ignited by fly ash.

My horizontal flue extends about 4 feet from the side of the house......I was afraid of smoke stains on my light colored siding. Works fine with my Ecoteck Elena. I used 4 inch Duravent Pellet Pro pipe.
My installer used 4in simpson duravent. The cap points out towards my yard. I will have to see how it will work before I decide if I need the xtra foot on the end

Won't you have an issue with sufficient draft, and possibility of smoke coming back into the house? I thought that was main effect of the rise?
If it is going to be an issue, I will have to make some adjustments. The installers said it will be fine, that they have had no problems before. It has been to warm for me to run the burner for a few hours to see how it works. With it only being a 2ft run, will the draft be that bad? I wouldn't think but I don't know yet.

If the power goes out you might get smoke back into the house, or if your combustion motor fails. Under normal operation the exhaust is powered so a straight horizontal doesn't hurt anything.

Looking at the pic, I know it would never be in code where we live. It needs to be a certain height above the roof line, and minimum three feet from combustibles. In addition the OAK looks like it will draw the exhaust right back in.
My stove allows setting the combustion blower speed for the amount of draft that your flue configuration has : a faster blower speed can be selected for no-draft horizontal flue set-ups. To prevent smoke back-up into my house (should the AC power fail), I have the stove powered by a UPS, with an automatic auger motor cut-off circuit installed so that the UPS can run the combustion blower long enough to let the burn-pot run out of fuel before the UPS battery runs down.
I also hope that you're exhaust isn't facing the prevailing wind.....that will cause problems in a set-up like that.
The vertical rise helps keep some smoke out of the house in case of a power failure. These stoves use a power exhaust so no draft is required during operation.
We blew a fuse in our place several years ago and a small amount of smoke escaped from around the tube scraper... I wet a kitchen towel and laid it along the front of stove and it was not a problem for the few minutes the power was out.

I had a power out early yesterday morning and was surprised that the fire was barely affected with our straight out the wall on the Elena. The stove is vented close to the bottom of the stove too. Stove design has some of the affect of draft.

Is that other hole an OAK intake? If so, I'd strongly recommend you put some sort of cap or something to prevent rain and snow from going in there. Also make sure that the penetration is sealed. Looks a little hokey to me. Do you have a termination cap for your exhaust vent? If not, get one. I'd recommend 86'ing that 45 elbow, adding n 18" section of straight pipe and using a "turbo" style cap. Eliminating the downturn will help with draft and the cap will help mitigate the winds affect on things.
If you're siding is getting soot build up on it, tune your stove.

Here is another pic. The air intake has a drain style cap on it that is painted black. Looks like there is nothing there but there is. The cap is a turbo style that I can adjust. What do you mean by 86ing? I think I am going to get another 1ft piece and pit it on the outside. I will have a little more then 2ft clearance from the house. I plans on putting a hood type shield on for the fresh air. Thanks all for the questions and concerns you have about my set up.
86 = get rid of... throw away, etc.
You exhaust cap is a pretty common deal around here. I have a different style but yours should be OK IMHO.

The pic (on my phone anyway) looked like there was just a 45 for a termination. Adding another 1' piece is a good idea. Your owners manual should list specs and clearances for everything.
