I want to have some on hand in case I need it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Elwell Corporation\u2019s Timberline 2.0 furnace requires the use of a glycol that is labeled as GRAS (Generally Recognized As Safe), and particularly recommends Century Chemical\u2019s 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 <a href=\"https:\/\/timberlineheat.com\" target=\"_blank\" rel=\"noreferrer noopener\">website<\/a>. But now that I had that info, I headed over to <a href=\"https:\/\/centurychemical.com\" target=\"_blank\" rel=\"noreferrer noopener\">Century Chemical<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">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.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So there you have it from the proverbial horse\u2019s mouth.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I don\u2019t need any of this glycol at the time, but all my literature says to pay attention to the diagnostic screen as to when I may be required to add more.
