We bought our gas log set from Fireplace Concepts back in the late 1990s and it worked perfectly for many years It hadn't been on in 5 years and the previous serviceperson who looked at it said he couldn't fix it and it was then completely turned off. . Ben, Fireplace Concepts serviceperson, came today and got our livingroom fireplace gas log set up and running quickly. Very polite and also very meticulous. Checked CO2 levels, annd told us he would come back in the new year to install a separate gas shutoff valve downstairs since no one had previously done that and also put a lock to keep the chimney vent open as the previous serviceperson took it off and closed the vent when he shut off the unit. Very happy with the service. Should have had this done sooner, but the last guy made us think we had to get a new unit (maybe that was his plan). Highly recommend using Fireplace Concepts for service/repairs.
