Update

Tech service said that the newly overhauled heaters have tighter limits on the pressure switches for combustion air flow to ensure that the unit gets adequate flow. They advised replacing the combustion air blower, which is now done. Combustion air flow seems much more poweful. I'll post whether this solves the problem after my next long flight.

thanks.
