I have 3 nat gas hot water heaters that I would like to remove from the chimney and power vent through the foundation. I have already upgraded the boilers to direct vent units and would like to remove the chimney. I was wondering if I can use one power vent for all three water heaters? I would size the power vent for the total of all three heaters and use a separate control for each. I am located in RI. Thanks.

You would have to consult the installation manual for your specific heater, and contact the manufacturer. Off the top of my head, I believe the answer is NO. If I find further info, I will post it



This is from the Rheem install manual> " 7. VENTING - The water heater must be vented to the outdoors as described in
these instructions. DO NOT connect this water heater to an existing Vent or
Chimney - it must be vented separately from all other appliances. "


Here is the complete manual> http://waterheating.rheem.com/content/resources/documents/tech%20bulletins/1600%20Series/1607.pdf
