hello, i have a 1 year old set of propane gas logs. The first problem i had was moisture got in the regulator which cause them to go out when the temp got under freezing would restart when temps went up. dried it out and they worked fine until tonight. Heard a boom noise that we could feel and logs went out, nothing on fire and not an explosion so lit them again. after about 30 minutes with just the pilot onanother boom and the logs out again. could this be a faulty regulator from it getting wet? also a slight smell of gas when this happens.logs light perfect and burn great and ths happens with just the pilot light on.
