Inquiry (采购产品): Ameritherm Vent Dampers I am searching for a tankless water heater vent damper to reduce the amount of cold air that is brought into my home through the water heater vent. I have an unlined 5" vent serving a tankless water heater. Thanks in advance. **** Hidden Message ***** Stephen Compton 40216 Company: Clean Away Services E-mail: scompto1@jefferson.k12.ky.us **** Hidden Message ***** scompto1@jefferson.k12.ky.us
