This is our newest gas fireplace heater and has been a problem from the start. (We own 4 other brands, all problem free.) The salesperson at On Fire in Santa Rosa, CA sold it as an excellent German-made unit. I think, but am not a repair person, that the problem may be in the electronic parts which start it. An independent repairmen and one from Valor came out 3 yrs ago and confirmed after 2 hours that a bad switch was the problem. They replaced the switch and it worked. Now we are in a new year and new season with a new problem. The circuitry parts on its GV60 Mertik Maxitrol, a techie receiver box connected to the gas valve, starts, controls, and stops the unit from a remote. The unit was purchased from On Fire, Santa Rosa, CA 2014 and has been rarely used ( 2 seasons) since purchased. We purchased a second new receiver from On Fire because On Fire thought it would solve its problems. It didn't. If the pilot is lit, I need to get on my hands and knees and reach my very small hand under the unit to turn the left knob counter-clockwise several clicks to get it lit. If the pilot goes out and it will in 5 days, we will probably not get it started again! Stay away from this product. I have spent hours on the phone with On Fire, in person with a Valor official and with repair people getting this unit to operate. Valor is inappropriately named!
