2. Cleaning Firepot with Cleaning Rod & Firepot
Scraper
• Frequency: Daily or more often as needed
• By: Homeowner
• Task:
a. The appliance must be in complete shutdown and cool
and the exhaust blower off.
b. Pull firepot cleaning rod OUT a couple of times to help
shake debris loose. If rod is hard to pull, it may be
necessary to use your firepot scraper 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 firepot.
Corn clinkers can be especially difficult to break up.
