Bubbles - You need THEIR vent kit. It should be concentric, and within their run lengths one pipe inside the other. You need your make up air also from the same pipe. Never mind that the stack temp is quite high and PVC pipe will melt very quickly. I strongly suggest that if you are not sure what you are doing pay the tech to install it. I have my gas license in Maine the strictest state in the nation for gas and I see issues often by the DYI'er. Oil burns, Gas goes Boom.
