The Weber Ducane 31732101 Affinity 3100 Natural Gas Grill offers basic, solid, and very reliable functionality and features. It’s a no-nonsense kind of grill. There’s nothing fancy about it. It’s  just a perfect mix of simple, uncomplicated, and extremely efficient.

Plenty of Space for Cooking

The Weber Ducane 31732101 Affinity 3100 Natural Gas Grill has a cooking space that measures 418 square inches. This is a large cooking space for a grill. It is enough space to cook for a party of 4 to 6 people. Keeping food warm is easy with a warming space that is 132 square inches wide. That means you can keep your food warm while you cook other things.

Efficient and Consistent Heat

Cook food quickly with three stainless steel burners that provide the natural gas grill with the cooking power. The grill provides consistent heat that results in thoroughly cooked food. The secret is the porcelain enameled heat distribution plates that are installed in the grill. The overall distribution of heat is also good, and cooks evenly throughout the grill. This is in stark contrast to some cheaper models that sometimes have cool spots in certain areas. This product has an electric ignition. This makes it easier to light and safer than non ignition systems.

Convenient Temperature Monitoring

There’s a built-in thermometer on top of the grill’s lid that can be used to measure the grill’s  temperature. This allows you to adjust the heat so it’s exactly the temperature you need for the type of food you’re cooking.

User Friendly

A step-by-step guide is included in the grill’s package so you can assemble it on your own. Most people reported assembly to be at around one to one and a half  hours. Assembling is simple and mostly requires the use of a heavy duty screwdriver.
