Question: I just installed a Regency Direct Vent gas insert (U32). The question I have regards the operation of the fan. According to the manual, the fan will come on once the unit reaches operating temperature, and turn off when "useable heat" falls below a certain value. The fan will kick in after about 6 to 10 minutes after the unit is turned on. Once the switch is turned "off", the unit fan continues to run for anywhere from 30 minutes to 1 hour. This seems like an awful long time. Could I have a bad heat sensor, or relay inside the unit? I live in California, so the average temperature has been around 70 to 75 degrees. Could it be just too warm in California still? I just finished breaking in the unit. Answer: The temperature setting on the little discs that these inserts use is usually 105-115 degrees. It is surely possible that this much heat is built up in the stove for 1/2 hours after you turn the unit off. A full hour seems like it may be too long. I think the problem will solve itself as it gets colder outside.
