Dear Hearth.com Readers, I'm having an issue installing my Englander 25-PDV. I'm trying to do a corner install but no matter which way I try, when I twist and lock pipe from the 45 degree elbow to the clean out tee, the tee will not point straight up and down. I've tried several pieces of pipe in between and directly to no avail. Could the angle of the elbow be off from the slots on the elbow, or am I just too simple to understand this stuff? I'll go to Aubuchon's in the morning and cross my fingers that A) they have another elbow and B) it looks different from the one I have. Thanks in advance for any insight anyone here may have.
