Picked up my Republic 1750 a couple weeks ago, have it sitting where it needs to be. Now I need to run the pipe to the existing masonry chimney. Its approx. 30" vertical, then a 90 elbow, and approx 18" horizontal. Here is the problem: i dont like the 'snap lock' type pipe. I really want to use the one piece welded but of course my distances aren't going to match up to standard lengths. And the only telescoping length i have found is way too long. Can anyone offer some suggestions? I've been wanting to take a pic to illustrate the setup, maybe tonight i'll get to it and add to this post. I'm sure there has to be a way other than pay the dealer come out and do it.
