    When my stove was installed they ran the vent pipe horizontally, parallel with the house then vertically so the termination point would be 4 ft from upstairs window according to code. Thanks to this forum I see that the evl is greater than 15. If I ran the pipe vertically 6 ft so it was 2 ft below the upstairs window and came out horizontally 2ft would that meet the 4ft code or do I need to run 4inch pipe to above the roof line. I have learned a lot about proper stove maint & cleaning from this forum.

    Welcome Mike, a pic would be worth 1000 words in this instance.

    Or maybe describe the vent piece by piece from stove to termination.

    Smoke, Thanks for reply. I have pictures of 1st install which was direct vent which did not meet code. Installer returned, put on a clean out tee with a 90 degree bend to a 4ft horizontal run to the outside chimney, another clean out tee with a 90 degree bend to a 6ft vertical run up the outside of the chimney. The EVL seems far in excess of 15ft. Termination point code for my stove is 2ft above window and 4ft below. If I did a vertical run between the windows to be 2ft above downstairs window only leaves 3 ft below upstairs window. If I came out horizontally 2ft can I combine that with 3ft to meet and exceed the 4ft termination requirement or do I need to go with 4inch pipe. Under current setup I have to clean vent pipes often. I pulled the combustion fan and the blades were pretty clean. I did a little scrapping and sprayed some graphite on them.

    Still confused on how the interior venting is configured.

    Is it ok to direct vent a GF55?

    Stove is located on 1st floor. There is a 3inch adapter pipe that goes straight through outside wall. Adapter pipe is 18 inches.
    At least 5ft vertical is recommended if pipe goes straight through wall. Hope I explained that clearly enough.

    Tough exit location with those three windows. What's that exterior chimney used for ?

    5ft is recommended not required. Outside chimney is for oil furnace. I did not have many (any) options on where to place the stove inside the house.

    I'm kinda slow. So in the first pic you posted it comes off the back of the stove then straight out the wall?

    If so I agree just turn it up and run it between the windows like you describe, using a tee, maintaining proper clearances.

    The termination must be 4' from the bottom of the window combining 3 with 2 will technically place the vent at 3.605+ feet as far as clearances go a 3 foot section would place it at 4.24+ feet. But supporting it would be an issue and it wouldn't look all that great and you would have the added drag of horizontal vent in the run and likely be over EVL for 3" vent.

    I was not very clear on what the current vent pipe setup was. The only photo's I had were of the first install. They had to redo pipe setup to meet code. Here is a photo of the current configuration which is certainly over 15ft evl. Sorry for any confusion and I appreciate your help and advice. The upstairs window is a slider and opens.

    Actually you descibed it pretty good. I just didn't think someone would actually do that. Man that looks like a chit load of horizontal.

    Your idea of running it between the windows stopping short of the upper window seems good. if you can maintain clearances.

    Holy Chit!! That stove burns with that set-up?!?!?

    I would be closing up shop on the 2 windows between the vent. As long as they cant open (place a boad, screw, lock, etc on them) then it would be fine to Direct vent or have a 90° and only 3 ft vertical.

    Most Stoves are 4' from a window, unless its an un-operable window (cant be opened).

    Can you get the needed 4' below the upper window, while being 1' above lower windows? If so, then go that route, so the windows are still operable. Otherwise, I would be closing up shop on the lower windows.

    Along with selling some pipe ;)

    Away at my daughters soccer tournament this weekend so I did not have a chance to respond. The girls to 1st place so it was a good trip. If I go 1ft above downstairs window I will make the 4ft below upstairs window code. I am planning on redoing pipe next weekend. Hopefully my stove will run better or at worse I will have to clean the vent pipes less frequently. Thanks for all of your help.

    Ouch, I'd have done the spike that little window routine and gone up the required distance above the first floor windows.

    Dexter the stove will burn until the ash gets to filling up the plumbing and then it will make a mess and not burn well at all.
