Is the 300° F stack surface temperature essential?
Yes. At 300° F and up, ACS Liquid develops its catalytic effect. This is why it is important to run up a small, brisk fire at least once a day, after treatment. Catalytic combustors (where in use) often don’t “light up” under 500° F or higher, so here is an efficiency gap ACS also fills. Does it help to spray the creosote in the chimney? Not in the upper “cold” area, because it won’t reach catalytic temperature. It can help in lower areas and in and above the smoke shelf area. The catalytic vapor created in the firebox will condense on to the glaze up in the flue, gradually converting it to a harmless state, easy to remove. Any need for treatment in spring and fall? Application of ACS is critical during “low-fire” and “intermittent-fire” periods. A stove “put to bed” in spring after treatment will be ready to go next season, and can be easy to clean. Untreated creosote and soot can cause nasty odors during the warm and humid months. ACS Powder is an excellent deodorizer as well as creo
