I'm trying to locate an owner's manual for a FMI GLS650 Victoria Series natural gas unit. I've been to their web site but that model is not listed? Customer is having an issue with log placement, their unit has 5 logs, but the manual that was left with the unit only shows 4 logs. The front log continues to carbon up due to flame impingement. I repositioned the front log yesterday to where I believe it should be, but would like to view the manual to be sure. Any info would be appreciated.
