Right off - Hi! I'm new though I've read many posts over the past year while researching stoves. I'm getting ready to buy our household's first pellet stove. One of the resources I'm referencing is the EPA's "List of EPA Certified Wood Stoves." (page https://www.epa.gov/compliance/list-epa-certified-wood-stoves, direct link to doc https://www.epa.gov/sites/production/files/2017-08/usepa-certified-wood-heater-list.xlsx) The very first column is labeled "Out of Production?" As it happens, a stove I'm considering has an "x" in that column. Since the spreadsheet is a bit awkwardly put together, I'm hoping someone with more experience using that spreadsheet can confirm that the EPA's notation does mean the model is being discontinued AND their data is reliable. Specifically, I'm reviewing row 324, HP22 ComfortBilt. Any help would be greatly appreciated. Also welcome any thoughts about ComfortBilt and their HP22 model.
