I purchased an HP22 Pellet Stove this year and am enjoying it so far, with one exception. I have been trying to get the flame dialed in to what the video shows for Levels 1-5; however, I am running into difficulty doing that. By working over the phone with (Clint & Johnathan who have been very supportive and understanding) there appears to be an airflow issue that we cannot put our finger on. I am concerned that when the real cold comes in I will not be getting the maximum efficiency of the stove and will thereby be disappointed. The Tech's Clint and Johnathan have been great to work with: but sometimes I believe you get to a point where you need a "District" Rep or Technician that was available for fieldwork to get a particular problem resolved. The over the phone Tech Support has been great and hats off to Clint and Johnathan! They are very understanding and cooperative, but I believe even they get frustrated with only having the ability to work via the customer and the phone to resolve problems. You know how it is when you sometimes can't see the working system or mechanical part to resolve a problem. I guess I will keep trying.
