air intake specs

Scot_4

I have a buderus oil fired boiler with a Riello burner currently installed in a fire station. Our current air intake comes into the building via sch 40 pvc with 7 90's overall length 20'. Wow....

So I have been having problems with the location of this intake and my new heating company wants to move it, reduce the 90's and length. I am in agreement. However I do not know what the recommended intake material should be. Codes is of no help in my area. I would like to know for my own piece of mind. Any help would be greatly appreciated.

I don't sell Buderas but it should be right in the manual.
Here is the link for there manuals. Next time mention the model.
