    I just ordered a new harman p43. (At a very reasonable price i might ad!) I've heard some people say they like the pipe inside and some outside. I was wondering if i should put the rise inside or outside the house, or if anyone suggests not putting a rise at all and just running it straight through the wall. Any ideas comments suggestions are more than welcome! thanks in advance..... Mike

    If the manual allows a horizontal vent by all means go for it.

    If you must have a rise it is generally better if it is inside rather than outside so the exhaust gases do not get a chance to cool off before they exit the venting.

    I have a Harman P43 that was installed this past August. I am vented straight out through the wall. Vertical rise inside of only about 7" to clear the baseboard heating element. On the outside the end of the vent stops about 2 feet from the house. Just enough to hit my head while mowing! ;lol

    I like inside and agree the warm inside air provides better natural draft.

    We just went straight out because the venting came with the stove. however if we do get around (money wise) putting up a vertical we will do it on the outside.

    I sure would not want the clean out T on the inside of the house.

    Who uses their tee, I can get practically everything with the dreaded LBT from outside without opening up anything.

    I would go up and out. That way if you ever replace the stove, you can reuse the hole through the wall.

    Putting the vertical rise inside the house costs a little more money and the stove will sit further away from the wall, black pipe cost more $$$. Putting the vertical rise outside the house looks like heck. Running it horizontal looks better but you will not have a natural draft if there is a power loss. This is the cheapest way to go but take the ground into consideration for leaves to catch fire and bushes that need to be removed.

    Can the pipe be painted black on the inside? Any concerns with the cleanout tee mess on the inside? Do you know what an LBT is?

    Leaf blower trick. Do a search for it and lots of results will come up.

    LBT Leaf Blower Trick, cleaning the soot out of the stove and venting using a leaf blower with vacuum capability.






    Do a normal stove deep cleaning and then let the leaf blower remove the soot that you can't get to..

    Clean the oils off of the vent pipe and use a high temperature stove paint on the venting.

    Very little soot is in the vertical section of the venting most is at the bottom of the tee and in the horizontal portions of the venting.

    With a flexible shaft vent brush system or dryer vent lint cleaning system you can loosen up the soot in the vent system from outside it will drop into the clean out tee area and then using the leaf blower suck it to the outside of the house no soot inside at all.

    Just found a lot of justification to buying a leaf blower at the big orange store. :cool:
    Thanks Smokey.

    I painted mine black with hi temp stove paint.

    As for the clean-out I plan on adding one the Selkirk vacuum ports as shown in the second photo below.

    Very nice install and I really like how you adapted your own OAK. :)

    Can you give us a zoom picture on that? ;) What size fittings did you use from the plumbing dept to accomplish that? Will that vacuum cleanout vacuum attachment work with any T? I plan on using PelletVentPro.

    The fittings are 2" galvanized.

    I think the vacuum clean out is just for Selkirk VP piping. And my surge protector wasn't hooked up in that photo but is now!
