    Just purchased a QuadraFire MtVernon. Can't wait to get it rolling, but I can's seem to whip out one of these 3 hour installs I keep hearing about ;)
    Anyhow, I am planning on venting the exhaust over my deck because it is the only place I can do it other than going out the roof. I asked a few people who had them how hot the Termination Cap got on a "out the wall" install and they said it was not scalding to the touch for the most part. I asked the dealer if the deck thing was an issue and they didn't shrug it off, but they weren't diametrically opposed against it either (I guess it was the sales department). After all of this, I buy it and the manual specifically states not to install the TC over a combustable grade. However, that can be interpreted as a dependency upon the minimum height requirements, it then goes to say it only has to be 24 inches minimum from combustables. I am reading it how I want, obviously, but I need a no BS answer on if this is a dumb thing to do. I am associating the term grade with anything under a TC. Never heard it referenced in that way.

    Here is some site survey info:
    - the thing is going to be 4-5 foot off of the deck, over double the recommended side-to-side combustable limits. I am in Nebraska where there is a steady to knarly wind most of the time
    - all other recommendations are staunchly followed

    Questions:
    1. Are there embers or unburned coals flying out of the exhaust on these pigs that actually pose a real risk (assuming you keep it maintained and burning efficiently - key for any safe operation)?
    2. How dumb is it to run a 45 degree angle straight off of a 90 degree angle in a venting application? The unit is in a corner and I may have to run out the stove with the adapter to the T-pipe, into a 90, then a 45 before bringing the rest of the pipe back up and to the middle and out of the adjacent wall. Since having to learn a lot about home construction with this new-old house, I have realized that some of my first solutions to problems end up being cardinal rule number one dont's - ha.

    Any advice would be greatly appreciated...

    best answer is to download the manual and install it as recomended. There is code language with relationship to windows doorss and decks and walk ways. There is also code lauguage concerning snow dept.. And yes the termination caps can be hot enough to burn shin. this varies with the cap manufacture and stove manufacturer and capacity of the stove.
    The manual should tell you what is required and proper venting concerning the run and elbows termination height and locations.

    Asnwer to question 1, yes quite a few embers fly out of there. I havent personally seen them catch anything, but they do spark.
    I dont realy understand your venting situation, but, if you ahve a T, then go up x amount of feet. Put your 90 on, cock the 90 at 45, then put your horizontal pipe on. Make shure you install a thimble. And do exactly what elk said. Read your manual.

    I have the same stove and horiz. vented out the wall with a 2 foot pipe. It is about 4 feet from the ground and 1.5 feet from a hedge. It spits out sparks pretty good. they typically go out before contact but some do stay glowing for a few secounds. I had to put my tipi poles on that side of the house and the tip of 2 of them are near the cap lying on the groud but on a 2x4. The tips all have 3 foot nylon streamers attached and I did notice burn marks on 2 of them. This is in the pacific northwest and has been a fairly wet winter. The wind can sometimes create quite the fireworks show sometimes when she is set on quad. Ive thought about ounting a steel trash can under the cap to catch the sparks and ash.

    Thanks wahsega. That gives me something tangible to compare to. I read the manual about 20 times before I posted and it told me nothing specific about decks, or pipe configuration "don'ts." The only thing it gives you is a chart on how to measure pipe feet. I had seen posters taking the initiative to overlook the manual to give their opinion on other posts, but I guess that was a special individual. Gee thanks, for the RTM advise guys, would have never guessed!
