    I am picking up my Harman p61 on friday. I would like to run the vent thru the roof. Are there any pros and cons of doing it this way. Also in terms of expense is it much more exprensive than thru wall?

    It is more expensive from the standpoint of you need more pipe. That stuff isn't cheap

    Uh... I disagree. You STILL must go just as high as if you went
    straight up (legally) AND you need more pipe and elbows etc.

    You lose draft. You get more creosote. You are very dependant
    on the brackets supporting the weight.

    Yes, if you are going to try and beat the system, it is easier and
    cheaper. But then you have to worry about melted siding.

    I originally was going to go out the side and said screw-it and
    just did it the right way.

    I did the ceiling hole one weekend and the chimney the next.
    Buy a kit just for this. That way you KNOW you have everything
    you need.

    Advantages are that you don't have some goofy looking pipe scabbed onto the side of your home. You have an appliance vent that will likely be mistaken for a water heater.

    Another advantage is draft in the event of a power outage will be superior with vertical vent.

    Finally, cleaning will be easier with no bends.

    I consider vertical and through the roof an ideal method for all appliances. The only negative is the possibility of rook leaks.

    The local stove shop just completed a pellet stove installation across the street today. Straight out the side of the house. UGLY! The pipe sticks out maybe 18". But I guess it`s legal huh?

    There's no vertical section outside?

    Is there a roof overhang?

    How about vinyl siding?

    At the minimum, it will soot up the
    outside of the house.

    Isn't that why it has to stick out so far? to keep from sooting up the house?

    what special installation considerations are there for vinyl siding?

    My Harman Advance has been vented directly out the side wall now for going on three years. I have vinyl siding, and have not had major issues with soot building up on the siding, or any heat problems on the siding. My pipe sticks out about 22 inches. In the spring, as part of the end of season cleaning, I hose off the siding to clean it.

    Hope that helps.

    If your stove is burning correctly, there should be no soot on the side of your house. As long as you install the chimney correctly there will be no "melting of the siding".

    Go to Dura Vent's website. It will tell you everything you ned to know. Vertical venting can be done but the parts list is more than a through the wall kit.

    I've seen a chimney part called a "house shield". when is that required? looks to me like the wall thimble should perform the same job...

    Yes the WT will do the same job as the House Shield and is about the same size as the old Pellet Vent or Corn Vent WT. The PVP-WT are smaller than the house shield.

    but...a thimble is always required, isn't it? so...why would a house shield ever be required?

    Hi,

    Thanks for all the replies. In terms of cost what am I looking at inn terms of price. I figure I need about 12-16' of pipe. Unfortunately I am buying my stove ot of state and am on my own in terms of installation.

    Thanks

    It is cheaper to go through the roof. For one thing you have to buy less type A pipe, for the second thing...through the house and roof will keep your chimney gases warmer and create less creosote.
    I just did it. Easy, once you know your product

    There is no class A chimney needed or creosote on a pellet stove.
