allseason Posted July 9, 2013 Report Share Posted July 9, 2013 Here is a unique situation regarding a water heater, natural gas supplied, natural draft with combustion air supplied via a duct from the large, vented attic. 1996 townhouse and this is the original water heater. There is a closet in the bedroom, at the rear of this closet is a second closet in which the tank is located. This closet is not a dedicated enclosure as the entry door is not fire rated or self closing. I don't know the rating of the wallboard. It is definately a storage closet, not a utility area. How is it that this was approved by the AHJ, it likely exists in all of the other units (over 50 t-houses)? Opinions?

Darren Posted July 10, 2013 Report Share Posted July 10, 2013 Same way a townhouse development in Riverdale got CO's when the furnaces & water heaters in the garage closets were slightly elevates but not the required 18 inches. Some inspectors don't know the codes. Quote Link to comment Share on other sites More sharing options...

What was the hot water temperature after running the dishwasher? Lukewarm I bet. Was the cold water heater thermostat set to "High"? Probably. Will it leak one or two weeks after the new owners move in? Probably. Quote Link to comment Share on other sites More sharing options...
Hearthman Posted August 2, 2013 Report Share Posted August 2, 2013 Ditto plastic pan and where does it drain to or does it have a wet alarm? No sediment trap on gas line Where is this MUA duct? What is the BTU/hr input rating-40K? Any pics of the vent connector attachment to the B-vent at the ceiling? Are there any screws on those connector joints? If residential, not aware of fire rating for the closet as opposed to the separation btw occupancies. Quote Link to comment Share on other sites More sharing options...
