House is 5nyrs old. Everything is sized right, gas, water, twin pipe intake/exhaust. 3" dia Vent only runs less than 2 ft., and has the required intake exhaust separation.

The rinnai is located in an exterior water heater closet. I made the vent cap and was in a hurry so I may not have enough vent area and hence restricting intake air flow. What error code would that give?

also i will recheck that the DIP switches are set correctly.
