How to provide fresh air to my boiler?

This might not be the proper location for this thread, but, here it is any way.

I have an 80% efficient boiler. 80% so it's not direct vented. Since I have tightened up my basement I'm going to need to provide it with fresh air or it will be less efficient and it will start dumping CO into the house. I could pay the HVAC guy to do this but 1. I don't have money and 2. it can't be too complicated. Does anyone know how to go about this? DO I just run an open PVC pipe or something like that through the wall up to the burner? That would be one big hole for air to leak into the house.
