I contacted the company the other day to discuss the loud vibration that is heard and felt throughout my home when the stove is starting up. The told me to lower the flame height to -2 and to manually adjust the heat output to medium or medium high which should eliminate the problem. I still have the problem 2 days later and I don't think it is right that I cannot run the stove with high output and utilize the quite features advertised. Has anybody got the same problem or other suggestions.
