Joe,
Camco one gallon GRAS Boiler Fluid which has ready to use on the label was used for many years by Aqua Hot Heaating Systems. They recommended that the one gallon size be cut 50/50 with distilled water. Camco has a one quart size that requires two quarts of distilled water to be added for use in the heater.
Lately, AH has moved to Century Brand GRAS boiler fluid which is ready to use in the one gallon container.
I like the Camco Brand. Both brands and other GRAS boiler fluids are fine.
BUT, your 1998 Newell uses regular engine antifreeze, NOT GRAS boiler fluid. Mixing the fluids is not recommended by Aqua Hot.
