Amtrol Expansion Tank Install

[M1687]

Is there a spec for how close an Amtrol Expansion tank can be located to the high temperature/supply side of a wood boiler? The directions did not reference this.

Assuming the ET is designed for hydronic (not all are), it should handle the temperature of any typical circulating water. I'd guess that the surrounding air temperature never exceeds the water temperature except in the flue.
