| I'm having troubles with my natural gas furnace I put in. It's a goodman high efficiency furnace. Anyways, I think the exhaust PVC (2") is creating to much back pressure or maybe the little pressure switch is too touchy. The pressure switch is basically there for a safety measure to make sure the exhaust gas fan is working right. So I'm wondering if I should put in bigger PVC pipe with one less 90 elbow, or could I buy a less sensitive pressure switch? | |
