Rich, I dont have a picture handy, but I used a vinyl siding 'block' - it's basically a square or rectangle, color matched to your siding, that has the 'J' channel built in. They make them in different sizes for lights, outlets, switches, etc.... Drill the big hole in through your wall wherever you want the pipe to pass. Make a similar sized hole (centered) in this block, then use the block to mark how far back you need to trim the siding. Mount the block, tucking the siding into the J channel, then pass your pipe through. Remember - the pipe that passes through the wall needs to be double wall.Special55 said:

I'm familiar with the trim blocks as I used them on the house for exterior light fixtures. I didn't know they made them big enough for a thimble though. Shouldn't be too hard to match as the siding is just white double 4.
Did you use a round or square thimble? The round seems to be more readily available and pretty inexpensive.
Yes - I have that same thing - There should be two pieces, one from the inside, one from the outside. That helps to keep the double walled pipe away from any combustibles. My inside walls have yet to be insulated or finished - so that thimble is just hanging there on the pipe. The outside flange is glued with RTV sealant - probably could have gone with silicon - to that vinyl block we were talking about. I can see the plywodd still from the inside an there's no leaks - so this should be good for you too.....Special55 said:mjribeiro,
Sorry for the slow response but I didn't have a PC handy yesterday. I just want to clarify how you intalled your vent. I was planning on using something like this
Did you put this on the outside of the square trim or behind it up against the sheating? How did you seal your pipe to prevent water intrusion?
Sorry for all the questions but these things come from the store without instructions.
Thanx
