When the pellets start to get that color that is an indication that they are spent.
Yes, its from the burner.
They have plenty of refills out there.

The content of that closed loop combustion "circuit) is air& nat gas fuel into the combustion chamber--combustion happens -- in and thru the perforated/sieve-like burner cylinder. burner (closed at the bottom).
Products out are products of combustion (gaseous and what appears to be this rust (from the deteriorating burner).
The gas is condensed per design to exit thru direct vent flue and as liquid condensate (at Ph of approximately 3 highly acidic and corrosive) Exits bottom of burner , thru trap and into Axion neutralizer. Ph out of neutralizer is 7.8-8.0. Alkaline. Neutralizer is doing its job. Is the discoloration (as I suspect) accumulation of burner rusting/failing/deteriorating and that is what need replacing ? I'm asking for things I don't know. Four local plumbers ..none even mentioned neutralizer.Or rust in captured condensate. The jobsite is not in Baltimore.0 -
Discolored neutralizer pellets are the norm. The discoloration is not from the burner and not from the heat exchanger, rather the products of combustion. I see it mostly on natural gas boilers because that's 99% of my business, but probably on propane as well.
On Gianoni heat exchangers, you see a buildup of these products of combustion; what we call coffee grounds.

Pulled top off fire chamber, Burner checked and in good shape,
dadial flue ways at bottom of chamber clear. .
End of season do I flush the "coffee grounds" and refresh/re-pack cylinder.0
