palmettoinspect Posted November 30, 2010 Report Share Posted November 30, 2010 Is it okay to install this tankless water heater directly below the for a fireplace? The direct vent is three feet from the regulator in the picture but not by much and 2 ½ from the window. I couldnââ¬â¢t find anything about installing the water heater below or that close to the direct vent just doesnââ¬â¢t seem right. Any thoughts are appreciated.

Richard Moore Posted November 30, 2010 Report Share Posted November 30, 2010 Check out http://www.rinnai.us/documentation/down ... _EN_FR.pdf , page 28. US installs require 12" clearance to "the combustion air inlet to any other appliance" (30" in Canada). I'd say you have that there, if only just. The other way around, so to speak...because the hot fireplace exhaust gas will rise, it shouldn't affect the water heater combustion air.

Garet Posted November 30, 2010 Report Share Posted November 30, 2010 What would keep those supply pipes from freezing when there is no water running? Or does it never get that cold in Charleston? Quote Link to comment Share on other sites More sharing options...

palmettoinspect Posted November 30, 2010 Author Report Share Posted November 30, 2010 What would keep those supply pipes from freezing when there is no water running? Or does it never get that cold in Charleston? Yeah last winter we had 14 straight day of freezing temperature which set a record and very unusual. So if you asked me the same question prior to last year I would have said no it doesnââ¬â¢t get below freezing here very much. I did recommend insulating all the water lines under the house and to tankless water heaters though. Itââ¬â¢s crazy what freezing water can do. My father in laws brass faucet split in half out at his dock last year during the record freezing. Quote Link to comment Share on other sites More sharing options...

HAHA same thing with the whirlpool tub in the master bathroom. Quote Link to comment Share on other sites More sharing options...
