Weber Summit 7120001 S-420 Liquid-Propane Gas Grill Review

Do you think of cooking outdoors as something like roasting a hot dog on a stick?

Didn’t think so. Outdoor grilling is an art form for some of the most talented chefs. You’re probably one of those if you’re considering Weber’s Summit series. If you’re looking to do a little (lot) more than a weenie roast you’ve come to the right place. Apparently there’s not much the Weber Summit 7120001 S-420 can’t do for you.

The Weber Summit 7120001 S-420 Gas Grill Takes Full Advantage of Stainless Steel Quality

It appears from its control panel to its stainless-steel burners, the Summit S-420 is clad in stainless steel that looks as good as it performs. Stainless steel cooking grates hold up to years of heavy use while delivering a consistent cooking surface.

The Summit’s stainless steel burner tubes can withstand the slight amounts of water you get with propane that’s notorious for corroding other burner tubes. The stainless steel side burners make preparing sauces and side dishes a snap, with easy cleanup and premier rust resistance. The stainless steel shroud protects the grill from the worst of elements and contains a built-in thermometer that monitors cooking temperatures with precision.

The Weber Summit 7120001 S-420 has Unique Grilling Capabilities

Flavorizer Bars:

Miss that smoky flavor from drippings sizzling on hot charcoal? Weber added its own unique stainless steel Flavorizer bar system to the Summit line. These heated Flavorizer bars capture drippings and send their smoke and essence back to the grill. Their perfectly designed angles funnel any extra drippings into an angled easy-to-clean grease tray and catch pan to prevent burner tubes from clogging, which maintains even cooking.

Sear Station Burners:

Get ready for a steak like you’ve never tasted. A powerful sear burner allows you to step up the heat and sear meats to perfection, while the regular burners maintain consistent heat for cooking foods through.

Generous prep surface and sizeable side burners:

These features allow you to multi-task during grilling time. Grab a beer, line up your seasonings, pull out the cutting board, and keep your tools at your fingertips with the stainless steel hooks.
