Hi we just got a new Heatherstone Mansfield with the new EPA approved catalyst and are wondering if we need to be concerned about lower flue temps than we used to run with our old Mansfield. When the catalyst is in the safe zone for operation and engaged, we often are not able to get flue temps above 250 . That's with a new double-walled stove pipe and thermometer at a foot above the stove. We're burning 100% elm coz that's what drops all over our farm. What we're burning right now is not as cured as we'd like yet -- long dead, but not split until fall -- so not ideal, but far from green. Should we be concerned about the lower flue temps, or is that fine as long as we watch the indicator for the catalyst and only engage it when it is in the safe zone?
