As far as I know if you get antifreeze not clear water by the exhaust only when the diesel burner runs there are 3 scenarios.
First off the system has to be hot or pressurized to 17 PSI too identify an antifreeze leak.
1. The stir pump is leaking - I believe it is the middle one in the stack.
2. The tank inlet fitting leading from the stir pump to the antifreeze tank leaks - follow the pipe and may have to move the insulation a bit to see if it leaks there. The stir pump only works when the diesel burner fires up. Will not run on Electric element heating.
3. The combustion chamber leaks
Look at all the pipes closely and read the AHE-100 service manual. If you don't have it download it here:

Maybe Rudy can offer better insight.
