It might be a direct vent mobile home water heater installed in a house. This is only a guess but check underneath the water heater and look for a opening. "
Rob Buchanan replied to Rob Buchanan's discussion Domestic HWH diverter missing, or just different?"Strangely, it does slope within normal limits. I hadn't thought about flue gas condensation being a problem, though. On the plus side, there are a handful of CO detectors around the house.
The next step will be a full CAZ. Having not identified…"
tedkidd replied to Rob Buchanan's discussion Domestic HWH diverter missing, or just different?"Looks almost perfectly horizontal. Think they took a level to it (lol)?"
Timothy DeLuca replied to Rob Buchanan's discussion Domestic HWH diverter missing, or just different?"Have you done any CAZ testing under worst case situations to test for combustion gas spillage? I agree that this horizontal venting holds a lot of potential for dangerous CO spillage. What are the rise, run and sizes of the flue pipes, including…"
Robert Riversong replied to Rob Buchanan's discussion Domestic HWH diverter missing, or just different?"The primary purpose of a draft hood is to maintain a constant, and not excessive, draft from the appliance, much like the barometric damper on a furnace flue.
In many jurisdictions, you can't vent a gas appliance into the same flue used by any…"
Rob Buchanan replied to Rob Buchanan's discussion Domestic HWH diverter missing, or just different?"So, if I'm reading that correctly, as long as there is no pressure differential between the combustion air supply and draft hood, it is technically in compliance. The combustion air intake and draft hood are in the same room.
As far as…"
Sean Lintow Sr replied to Rob Buchanan's discussion Domestic HWH diverter missing, or just different?"I am by no means an expert in this area & you should call one in to look at it but the applicable code is:
IRC 2009 - G2407.3 (304.3) Draft hood/regulator location. Where used, a draft hood or a barometric draft regulator shall be installed in…"
Rob Buchanan replied to Rob Buchanan's discussion Domestic HWH diverter missing, or just different?"I was back in the residence today and took a look at the underside of the box in question. It is most certainly a draft diverter, but it looks as if it is decidedly unsafe. Based on the stack effect, the warm, moist air would circulate at the top of…"

Hi everyone,I haven't been in the game too long (two years), but I have been in a few hundred houses. I have never seen a DHW exhaust like this in any house. There is no draft diverter at the top of the water heater, and the exhaust is continuous until it enters the chimney. It is commonly vented with the 80% efficient…See More
