There is a metal plate on the inlet of the combustion blower. Make sure you could see all of the fan opening. None covered by the open plate. If it is covering the inlet a you will be able to bring the Max up even more with a FR of 99. I have seen the 110s w a FR of 48-50 max. When you see a 99 FR you want to adjust the max so you have hot coals right to the edge of the grate but no red coals falling off. I usually set the Max to the point red coal is just falling off the grate then back off by 2. It is important that the FR is 99.
