After adding a CO2 (carbon dioxide) meter, yes I also have the all important CO (Carbon Monoxide) meter also, I have decided to add a Oak to my Quad CB1200 to try to help keep the CO2 levels down in the Winter. For those of you who have a OAK, did you wrap it with pipe wrap? I have read that it can get frost? If so is this what you would use? (broken link removed)
Also not sure why the instructions say to make a 3" hole when the outside measurement on the intake pipe is 2-1/4".
