 |  "intake and exhaust"
, posted Sun 6 Jul 19:28  
I want to have a high efficiency gas furnace professionally installed. I have a brick exterior and it will take some extra work to installing the intake and exhaust pipes through wall into basement. I would like to do this part myself, since it is not really hi skill etc. I need to know what the pipe size and separation/ positioning requirements are for the PVC intake and exhaust pipes. Are there any general guidelines. This will be a approx. 60,000 BTU unit.
Thanks

I doubt there is one answer for all systems. You really need the installation instructions for the furnace as the manufacturers spell out all the requirements. There may be additional code restrictions for your area that will override some of those requirements.
While I love being a DIYer myself I just don't know how much this is going to save you and how you'd coordinate the work with the installer.
I would work with your installer to see what prep work they don't mind you doing and what kind of break it will give you on price. Maybe you could remove the old furnace, cut holes where they need them, etc.? A good installer probably won't mind the help so long as it won't affect their warrantied work. I would approach it from that angle.
Just my $.02

Oddly enough it may seem that installing pipe is easy but there needs to be a slight slope in the exhaust due to condensation.
Also every bend adds 4-5 ft to pipe length. Please ask the installer. There in more to it than just running pipe to save money.
My advise is that you talk to your installer and see how and where he/she wants it.
