We bought a Mendota Full View Direct Vent Insert in February of 2015. At first, the only problem was the off-gassing which set off the fire alarms in our house and lasted well over the 10 hour burn off period. Fast forward to one month ago (January of 2017) and the blower started making a high pitched whistling noise. We got the blower replaced. One month later (February 2017) the burner would not light. The pilot light was on. The remote worked (could turn on light, blower, etc heard the "beep" when we changed modes) but the burner would not light. Guys came out said it was "a burned out ground wire." They showed it to me and sure enough it was toast. They replaced that. Fireplace worked for about 30 minutes, then same thing happened. The pilot light is on but the burner will not light. The remote works fine and the thermostat key is in manual mode so it's not a set point issue. Any advice? Did I just get a lemon? This thing was $6,000 including electric, gas line, etc so not willing to go down without a fight.
