Trouble on the Roof
One of my customers here in Berkeley called me that his carbon monoxide alarm was alerting him to high levels of CO in the mechanical room . I picked up ~500ppm at the boiler with my analyzer, but wondered how it was getting into the house.
After shutting down the boiler, the owner told me that he had a new roof done in January and when I checked the termination, the new top had been pushed down so far as to almost completely block the flue.
I see this often enough.

The only way cold pressure can build is water getting in from a higher pressure source. If there is no domestic hot water coil or indirect hot water heater — it' the fill valve.
Re: Combining supply lines to manifolds?
If you total max flow is 5.5gpm use 1" with a tee for both manifolds
3/4 is good for 4 gpm
1" is good for 8gpm
Re: Ever seen one of these??
was there like a drying shelf on the bottom? looks like there are lugs to hold a shelf on the bottom.

if the threaded rod is long it will work.
if the split ring is over the insulation it will work.
