A while back we noticed some hydronic units exhibited excessive vibration. We issued bulletin TB13.003 and introduced a Vibration Damper Kit. This bulletin updates what we have learned and features our recommendations for controlling leaving water temperatures (LWT). This bulletin applies to combo and water-to-water units. If you have questions please contact technical support.
