Re: Old Coleman mod 3110-750 heater only

A note for Robert. Back in 2009 I rewired the heater in my old house with your help. Just wanted you to know it is still working perfect and has not had one problem since. We have bought a new home since and my sister-in-law is living in the old place. Thanks again for all your help.
