Get the correct Limit Switch, 130°, Atwood 35132
Your heat exchanger is NOT designed for that 190*F temp (iii limit switch)

8531-ii uses a 130*F limit switch (same for 16 thru 35 btu ii)
8531-iii uses a 190*F limit switch (same for 16 thru 31 iii & IV)
Simple check of PARTS List for the TWO different versions---- ii vs iii
