Walt's Corner

I don’t need any of this glycol at this time, but all my literature says to pay attention to the diagnostic screen as to when I may be required to add more. Problem is, more of what? Walmart antifreeze? NAPA? Checkers? I want to have some on hand in case I need it.

Elwell Corporation’s Timberline 2.0 furnace requires the use of a glycol that is labeled as GRAS (Generally Recognized As Safe), and particularly recommends Century Chemical’s part number 19910-C6T. Brady Shirrell from their service department quoted that to me in an email. I had to dig that out of Elwell since it is not listed anywhere in the accompanying literature or their website. But now that I had that info, I headed over to Century Chemical.

An email from Jeremy Southern from Century Chemical says it can be purchased at most Camping World supply stores. I was able to source it from Amazon for $60 for a gallon. I did see it up to $10 cheaper from other amazon stores, but I chose the one sold by a store with an 86% positive rating.

So there you have it from the proverbial horse’s mouth.
