Inquiry (采购产品): heat exchanger We recently have moved into our home which in the basement has an E-Z vent series 300 heat exchanger. The former owner had little idea about how it functioned nor a manual from the owners previous to her. Was this produced by your company at some point and could you tell me more about it? **** Hidden Message ***** Heidi Bixby NY 14559 USA Company: home owner E-mail: heidibixby@aol.com **** Hidden Message ***** heidibixby@aol.com
