: I think you have some problems here. Being a flatlander, I cannot advise on the altitude issues. However, your combustion air inlets are not even adequate for the water heater alone. Also, you didn't mention the BTU rating of the boiler, but in combination with that 75000BTU water heater, it is quite possible that your 3/4" gas line is inadequate.

There are charts and formulas in the National Fuel Gas Handbook which easily provide the requirements for you. I thought that good home inspectors had some familiarity with this publication.
