    You have it right, it's the low voltage draft adjustment screw.

    Kevin, glad to hear disconnecting the OAK has helped. Plug the end of it to stop cold air coming in the house through it. Like STB said, there is still more to do here. You should be able to attach that OAK without this happening, so it's worth further troubleshooting to find out what's really wrong there, for example is there a kink or obstruction in the pipe, restricting air flow?

    Another issue we see in the pictures is the way the exhaust flue is attached to your stove. That needs to be corrected. Based on your pictures, it's tough to see how the pipe connects to the stove right now, what is beneath that foil and silicon tape, do you know? Coming off the flue outlet collar on the stove, you should have an appliance adapter. That adapter is typically attached to the flue collar with a screw or two, and some silicon to seal it. Attached to the flue adapter you should have a couple feet of straight straight pipe going into an adapter tee, which the 4" flex adapts into. The tee will give you a proper way to clean out the flue.

    Honestly, based on your pics I would be hesitant to ask the same installer to come back out, because he really did you a dis-service with this install job. You may be better served to call out someone else to inspect and fix the thing. It's going to cost you some bucks, but it's the right thing to do.

    Not seeing a tee made me scratch a little. Hearing it was a dealer that installed it really has me thinking.

    Try 3 120 degrees apart, but I digress.

    I believe there is a straight pipe off the stove and then a curve pipe right to the 4 inch flex. Kind of like a "u" shape pipe. The guy said no silicone because it would be hard to take it apart and clean it.

    Definitely no "T". A curved pipe.

    You can use a plastic storage bag (qt. or gallon) or cut up an empty pellet bag to wrap around the oak pipe coming down from the chimney, & some tape to seal it up..

    Hi Kevin, The reason we use a tee where the 90º(the curve piece) is when you run this eventually you get build up in the long vent run. Heating and cooling of the run will likely have some of the build up fall down the venting, The tee section gives it a place to settle without blocking off the vent run.
    Hard to say by the pic's but the 90º(curve) looks to be single wall. Not a major issue as its in a masonry chimney, But the seems should be sealed as this is a pressure vent unlike a wood stove. Pressure vents push gasses out of the seams!! Preferable to be double wall from the stove to the tee. And an adapter the liner can attach too. The liner should be secured to the adapter with at least a worm drive clamp and not just taped to it.

    IMHO this is a very unprofessional install and likely would not pass any sort of insurance inspection. If you are smelling smoke it is also leaking CO's and should be corrected. Pressure ventings have to be sealed. The tee will let you have excess to clean. Please listen to what the others have passed on, We don't want you to be in harms way by someone that did a very sloppy install.

    Just my opinion, But I would not feel comfortable running this in its current condition. Please at least seal the leaky seams to help keep the CO's at bay. And then correct the venting as seen in the Harman manual.

    That's why he didn't silicone - without a cleaning 'T', you would need to remove the piping below the flue plate to clean every so often.

    He didn't explain that to you? Wow.

    Exhaust system must be gas tight.

    Kevin your install off the back of the stove should look similar to this. I too have a p68. I have adapter off stove to a 2ft piece connected to a cleanout T. Your liner then connects to the top of the t. There should be a coupling at the top of you T to receive the liner. Dealer gave you the bare minimum in this install. I have no silicone in my install. All my joints are sealed with silicone tape which is easy to remove if necessary. Has this install been inspected

    I would use the bang and have them redo the install correctly if possible. Is there a cleanout outside the masonry chimney? Would be a good place to pass through the OAK.

    Just a comment from a wood burner. If whoever did this is a factory authorized dealer/installer, you should be able to get your issues corrected by someone more competent and paid for by Harman. There's no excuse for someone who is trained by a manufacturer to not follow the manufacturer's recommendations/requirements for the installation of its products.. Failing to follow manufacturer's installation requirements shifts the liability (potential homeowner's insurance claim) from the manufacturer to the installer. Failing to fix a known faulty installation could then shift at least some of the liability to the homeowner if the homeowner continues to run the known faulty appliance in a deficient condition. Be careful and best of luck getting this fixed and by all means, hold the responsible party(s) accountable for their actions..

    You don't want to know. 750.00 but the stove pipe goes up 33 ft.

    Not yet. Do you recommend I call the town so legally he'll have to fix it for free?
