Below are the instructions from the manual. Working the firepot cleaning rod in and out has become more difficult lately. I thought this was due to build up from burning Stove Chow on low a lot recently. A through clean and inspection revealed no noticeable build up in the bottom of the firepot yet there was still a strong resistance when operating the cleaning rod about half way thru its stroke.I was getting ready to disassemble the clean out plate from the fire pot to get better access so I sprayed a little wd40 on the bolt that it pivots on to aid in taking it apart and low and behold it started working very smoothly as it was binding on the bolt. What would be a good product to lubricate this bolt with? It must get very hot. Cleaning Firepot with Cleaning Rod & Firepot Clean-Out Tool • Frequency: Daily or more often as needed • By: Homeowner a. Be sure the appliance is allowed to cool, has been unplugged and the exhaust blower is off. If you are just cleaning the firepot, there is no need to unplug the appliance. b. Pull firepot cleaning rod OUT and IN a couple of times to help shake debris loose. If rod is hard to pull, it may be necessary to use your fi repot clean-out tool to chip away material that has built up on the bottom plate of the firepot and to push out any clinkers. Larger clinkers may have to be removed from the top of the fi repot. Corn clinkers can be especially difficult to break up. c. T he firepot floor plate must be fully closed when fi nished.
