This B Type flue pipe from the gas water heater requires a 1" minimum clearance from combustibles. This one is in contact with the plywood ceiling creating a fire hazard.
These expansion tanks are required where there is a pressure reducing valve installed in the water supply and the utility supply pressure exceeds 80 psi.
