    You will probably also need the appliance adapter piece to connect the stove to 18" pipe. The appliance adapter usually is installed on the stove with Hi Temp RTV.
    Also buy a good surge protector to plug your stove into.

    Would it not be better to have some rise in the vent and not just go straight out?

    I would assume that more flow is better unless there is a reason these stoves run better with some backpressure/restriction?

    That stuff seems a bit pricey.
    I bought all my pipe from Lowes. http://www.lowes.com/pd_70661-76845...Search=4 "dura vent"&productId=1193737&rpp=32

    If you need the pipe black just paint it with hi temp paint.
    Good luck.

    Not totally sure, but any horizontal install I've seen was 3". I think 4" is primarily used when there's a long run of pipe and the extra draft it produces is advantageous in compensating for the additional pipe length.

    ok I just ordered everything including the adapter in 3". going to paint the interior pipe black.

    Question on clearance for the exhaust from the ground, does the exhaust termination need to be a specific height off the ground? The exterior wall is at ground level. outside is nothing but some old shrubs which i'll rip out with the truck. was thinking on putting gravel below the exhaust area for added safety.

    Stove starter make the transition from the back of the stove to the pellet pipe could also be called appliance adaptor. you need to be 2 ft above the ground with the termination cap

    You'll need 2 3/8" OAK flex pipe as well. It can be tough to find, though your Harman dealer should have some in stock. If not, any METALLIC flex pipe will work, as long as you err on the side of larger. Pick the brains of the folks at your local BB store if you can't find the exact size.

    Took a good look at my exterior. Cap should be 30"+ above the ground.

    Thanks I was looking into that. I'll contact my dealer tomorrow regarding the flex pipe. No luck finding a 2.5" flex in a quick search... 3" is everywhere.

    That's probably your best bet. You could use the 3" stuff but you'll have to get a couple adapters to make it work. An auto parts store would probably have them, but they won't be cheap. Then again, what your dealer gives you for a price likely won't be cheap either...so be prepared to say "how much a foot!?"

    WHen you install the oak kit, make sure the little hole where the fresh air will come in is set up so the metal tab partly covering it is pointing down (to NOT allow water in) instead of pointing up (like I did!!!) :)

    this will arouse some ire......my opinion....that P68 will eat up that Lopi and all its relatives for breakfast, then look for more......

    You may have noticed, the same site that I gave you the thimble link from, also sells flex pipe. It's only in 25' lengths for $140. Break it down to around $5.50 a foot and that MIGHT be around what yer dealer will charge, although I think mine charges a bit more. Whatever the price is, if it were me, I'd just fork over the cash for the right stuff and be done with it. Tape the ends on and you're good to go. My guess is you'll only need 3'.
