harman P68 Install question

Hi All,

I'm considering getting the harman p68 to install in the corner of my living room. Due to the space requirements I may pick up the side heat sheilds so I can put it 9 inches from the wall instead of 13 inches.

The question I have is around venting the exhaust pipe. In the install manual: http://hearthnhome.com/downloads/installManuals/P68.pdf on page 13 figure 15 it shows the minimum flue install option. basically this install has the exhaust pipe going directly out the side out of house with a 12 inch extension. Is there any down side to doing this type of exhaust setup. I know if power is lost without the raising stack pipe smoke could come back into the house but I may be willing to take that chance instead of having a rising stack pipe on the side of my house. It doesn't change the efficiency of the stove burning does it with the straight out pipe or the pipe extending 5-6 feet up?

Also any feed back on this stove? Good stove, good heat?

So I stopped by a dealer the other day and saw the Harman Outside Air Kit with the Vent in one unit, that is a pretty nice setup, the only thing I would want to have that behind the stove so you didn't see it as it is pretty bulky. The manual recommends if you do the vertical run to do 5 feet of raise and then go out the side of the house, however the dealer told me you could just go up a foot or two and go outside behind the stove to hide the wall kit. He said this minimal amount or raise would prevent smoke if a power failure occured. I do live in a pretty windy area so I'm thinking i should probably do the minimum of 5 feet of rise because it did indicate in the instructions that in windy locations this can help prevent issues from the wind. Has anyone had any similar experiences using these in Windy locations?

So here is one more question... I'm trying to plan out the pipe pieces I would need before I actually get the stove (I'm not picking it up until the end of November). My goal is to put this as close into the corner of my room as I can. I have bought the side heat sheilds so I can go as close as 9 inches from the wall according to the manual.

I am planning to come out of the back of hte stove, go into a T w/ the cleanout, then rise up 60 inches, then add a 90 degree elbow to the top of the 60 inch length and then go horizontally out through the wall. Once out side I will have a 12 inch section and then a horizontal termination piece.

The question I have (I'm hoping someone else has done a similar corner install). If someone had to guess, do you think I would need a 6 inch or 12 inch section on the inside of the house on the 90 degree elbow as it starts to go into the thimble. The walls of my house are built w/ 2x6s if that makes any difference.

The reason I am trying to figure this out before I get the stove is because ventingpipe.com is offering free shipping on all orders until Oct 31st. Any feedback would be appreciated.

So I stopped by the dealer today and he told me with the P68 it would be more than sufficient to do the direct vent right out the back with minimal pipe, I wouldn't gain anything with the rise except the change of smoke in a power failure, however he said even with a 5 foot rise it doesn't garantee against it.

So to try and save some costs it seems like I have two options to conceal all the piping behind the stove, let me know if you guys have any thoughts:

Option 1) come out of the stove with the adapter, than go to a 45 and a 24 inch section right out the house with the angled horizontal cap.

Option 2) come out of the stove with the adapter, go to a 90, rise a foot or 18 inches go to another 90 and then go out the wall 24 inches with the angled horizontal cap.

The only limitation I have on this is that I want to keep the fresh air kit where it goes out of the wall behind the back of the stove so you don't see it unless you look behind the stove. I was just wondering if having a slight rise would help in the event of power failure, however adding two 90's to the pipe for such little gain might be less effective having the straight shot out the side.

The powervent fan might be more effective with no restrictions blowing the smoke away from the house too and may prevent the chances of staining on the side of my house too?
