And there is where the problem lies
Soot on the draft hood..the 1st water heater had soot on the baffles in the middle..loud flame....it is not a crisp blue flame..it has blue but does look a bit lazy and had yellow in it...as I said even with door to outside open it still burns this way??? Is that not enough secondary air? Draft seems good..I can cup hand around and not have to move...although draft at very front does not draw as well as sides and back...does that make any sense? Gas suppy goes for 3/4 black iron to 1/2 OD copper tubing (so whats that 3/8 ID?) back to 3/4 black pipe where it connects to water heater.... been told that a fire Marshall would red line the heater just for that...think maybe one of the Sears plumbers may have said something?
And what cause combustions smells.......I am smelling something..I think any adhesive from the meatl tape the pulled off pipe must have burned off by now? They did put the read fire caulk on the connections but that shouldn't smell I would think...if you get on step stool and stand right above where first elbow comes up (HVAC guy called it something else) you can feel the heat rising and the smell..it is almost like a metal burning smell..can the pipe actually cook? I dunno I'm grasping at straws now...and since HVAC put that new 12x12 grate in the living room I now get that smell in my living area not cool at all...not their fault...the builder used sheet metal on the joists to use as a cold air return..and not the most air tight system thats for sure
