When I say upgrade the fireplace here is what I do.
The low voltage connections should be cleaned and soldered for a great electrical connection,why you ask well would electronics be as advanced if all the wire connections where just wire nutted or crimped "NO" "WAY"
The flame of the pilot generates less that 1/2 volt and less than 10 milliamps.
The piont is re-crimp and solder all gas valve millivolt connections.
Replace the wall switch because the contacts oxidies in a year or so.
Most wall switches have internal grease which can inhibite function of the the gas valve so excerising the switch on/off 10 times or so can clean the internal contacts and do this while the pilot flame is not lit.
So to recap,solder the millivolt connections,if using a thermostat bypass the anticapator by sliding dial to the solder piont.(mercury type)
Use an approved glass cleaner,also use compressed air with a double bagged vacuum cleaner to clean flue and fans and pilot.
