Hi to everyone. Just put our fec 500 into our new place. customers and owners alike are loving this thing. im very proud of the product that we are putting out with this unit. I have a couple questions for other owners out there . are there some parts in particular that i should have on hand. if it goes on the fritz . im assuming the ignitor is a must, but does any one have any suggestions for other parts to have on hand as our only back up is a stick burner , and it doesnt have the capacity that we need. i would appreciate any input from my fellow operators. also what do yo feel is the best cleaner for the bottom of the smoker , is zep the reccomended cleaner and does anyone use any other products. thank you for your time
