How do I prevent a gas grill from melting vinyl siding?
Position your gas grill at least 10 feet, preferably further, from your house so you don’t melt the vinyl siding. While it’s convenient to set the grill up right next to the house–allowing you to take advantage of the overhang of the roof or the shelter of the patio–the heat coming from your grill is high enough that you risk damaging the siding. If the siding starts to melt, this poses a fire hazard, according to Summerville Fire Marshal Ben Bunting. Bunting says that, while 10 feet is a sufficient space between your grill and your house, 25 feet is even better.
