OVERVIEW
First production 2005 stoves Serial #3384 to #3420 require precautionary replacement of both T-1 and T-2 sensors. The sensors located in the stove body sense the operating tem peratures and overall param eters of the stove. The T-1 sensor provides blocked flue and operating sensing while the T-2 sensor provides start up, shut down, and over tem p. sensing.
The first 26 units have a sensor assembly attached in such a way that may cause the stove to act erratically. As a precaution we are requiring replacement of the sensors and offering a repair credit. Please contact custom er service @ 800-527-4790x29 for further inform ation.
