What I get from reading the info from Aqua hot is this:
Pink and green are colors, they do not denote one chemical or the other (ethylene glycol or propylene glycol)
You can use propylene glycol in any AH unit, but you can't use ethylene glycol in the 2004 up AH units
Don't mix pink and green boiler antifreeze
There is much confusion about this, so if what I have surmised is incorrect, I welcome your corrections
And as David said, there is no substitute for reading the AH manual that came with your Beaver
