Frequently Asked Questions

Where does the name Evo come from?

The Evo circular flattop is a breakthrough product - the next evolution in cooking. We pronounce it "EE-vo" but also say "EE-vee-oh".

The outdoor grill market had reached parity with open flame cooking, and now Evo lets you create new experiences in cooking and entertaining. It combines the time-honored utility of a solid cooking surface (e.g. French flattop, Plancha) with modern technology to offer a variety of cooking techniques not found with other outdoor grilling systems or indoor appliances. So the name fits as we continue to evolve the way you cook!

What makes the Evo Flattop different than other cooking appliances?

Open flame outdoor grill or indoor charbroiler - One of the main distinctions is with an Evo Flattop you can control the heat and thus the cooking process. Cooking over grates allows the foods and their juices to fall into the fire and become fuels which ignite thereby changing the chemistry and timing of cooking. There is also additional pollution (air and/or noise) to be dealt with. While open flame appliances tend to scatter guests, an Evo invites your diners to gather around and share in the creation of a meal.

Electromagnetic induction – There are several advantages with Evo cooking appliances. Because of its good size, the Evo cooking surface can do the job of many pans at the same time where induction requires a hob for each pan/portion. Evo also allows indirect cooking with any of the pans you already have – each size and shape of induction pan is an additional purchase/cost. Evo flattops allow for more cooking techniques, and offer the opportunity for outdoor use where electricity is unavailable.

Cassettes and canned fuel systems – Heat is the big differentiation for Evo. The circular flattop system provides power, range and control which exceeds the other systems’ capabilities.

The Evo flattop has direct and indirect cooking versatility which allows for many culinary techniques and thereby a multitude of recipe possibilities. So to say Evo is just a grill or griddle is a major understatement.

Tell me about "seasoning" related to the Evo?

The cook surface of the Evo flattop is designed to hold a fine layer of cooking oil on its surface just like a good cast iron pan. Referred to as “seasoning” in the culinary world, the term reflects the fact that the surface gets better after many applications of oil over the years. Seasoning does two things: it promotes a non stick cooking surface and prevents oxidation when not in use. All Evo commercial cooktops are pre-seasoned at the factory prior to shipment. Routine cleaning of the cook surface (see Use & Care section) will actually re-season the cooktop as you clean up, so we suggest you do this after every cooking session. It only takes a few seconds yet is so beneficial!

To season the Evo anew, coat the top area of the cook surface with 4-6 tablespoons of a vegetable oil like corn or canola oil. Using a paper towel, spread a thin layer of oil across the complete top area. Heat the grill to medium high and allow the oil to burn-in to the surface for 10 to 15 minutes (covering the cook surface with the hood helps this process). Reduce the heat to low and apply a second coat of oil and then repeat the process. After the second ‘seasoning,’ slightly cool the cook surface and use the cleaning pad supplied with your grill to lightly rub the surface smooth. Take care not to remove the seasoned oil build up you’ve just applied - the tip here is to smooth any rough oil build-up that may have occurred during the seasoning. Finish by wiping the cook surface down with another very thin coat of oil using a clean dry rag. What you should observe is the coating on the cook surface is now covered with a thin layer of satin gloss oil that when cool is smooth and slightly slick to the touch.

How can I prevent food from falling off the cook surface when I sauté?

If you are having trouble keeping the food on the slightly convex cook surface, you may want to try using two metal spatulas instead on one. The second spatula can be used as a guard to prevent the food from falling off the grill as you toss with the other spatula. Especially helpful when you have the cook surface covered with food! Two spatulas also work well for flipping fish, burgers, etc. Slide one spatula under the food while using the second spatula to prevent the food from sliding. Once foods have begun to cook or caramelize, then they are more likely to stay placed at any position on the cook surface. Remember a variety of utensils may be used when cooking on Evo - spatulas, tongs, knives, etc - as well as pots and pans.

If you have foods skimming off the cook surface when first placed on, it likely means the temperature is too hot. Moisture is vaporizing to create a hydroplaning effect. Remember the Evo Professional model can reach temperatures over 675 degrees – better for boiling water rather than cooking foods. Try starting up your Evo at a Medium setting.


What can be done to preserve the cook surface handle plastic?

The plastic pieces on Evo handles are heat-resistent and grease-resistent. Standard cleaners like Simple Green, 409 and Windex work fine, and citrus-based cleaners are even better. Avoid using acid or alcohol-based cleaners.

Tip: avoid resting the spatula on the cook surface with the blade propped on the cook surface handle. Over a prolonged time heat will travel up the metal spatula and soften/indent the plastic grips.

How often should I clean the cook surface with the cleaning kit?

When you are done cooking on the flattop you should always scrape off the remaining food particles with a flat metal scraper or the side of a metal spatula and then rubdown the cooking surface with a thin coat of fresh oil. After the scrape and rub, you can then condition the cook surface with the cleaning kit if you like. Because this process takes less than a minute, we do it every time we cook with our Evo.

The ability to compartmentalize cooking on the large flattop means you generally clean up after the meal. However you may want to use the cleaning kit before dessert preparations to prevent any unwanted flavors from getting mixed with the dessert.

We also recommend using the cleaning kit before making pancakes, crepes or flat-breads. Not only will the food be easier to prepare, it will also cook more efficiently.

How can I speed up the cleaning time when cooking very fatty foods?

When cooking fatty foods (e.g. bacon, duck breasts) you can place tin foil in the drip pan where you anticipate the fats to run off. The foil will catch the fats for easy disposal once the grill has cooled down.

What should I do with the cooking surface when I'm planning a long term break from cooking?

It is most important to protect the steel cook surface from prolonged moisture. Keeping your cook surface oiled will help to protect the falttop, just like you do with your cast iron pans. If the raw steel is exposed to moisture and the elements (i.e. left unseasoned) oxidation may start. A cleaning and application of oil will take care of this, but extended lack of attention may cause pitting to the surface.  If you plan to be away or simply not cook for weeks, you should always store the cook surface in a dry place. Remember you have a fine piece of cookware here, so treat it right and you’ll enjoy it for years to come!

What do I do if the Evo outdoor propane model won't start?

If the burners won't ignite there are a few simple things to do.

  1. Check to see that the igniter battery is properly installed and that the battery is functional (has charge, and making contact). You should hear a clicking noise when you press and hold the igniter button. Evo uses standard batteries. If you are replacing a corroded battery, remember to clean the terminal points in the igniter assembly.
  2. Check the LP tank to make sure there is enough gas in the tank and that the tank valve is open. To open the tank valve, turn the knob on the top of the LP tank counter clock wise until it comes to a stop. Be sure to have the burner valves in the off position when you open the tank valve. If the burner valves are on when you open the tank valve, the regulator will think there is a leak in the system and automatically prevent gas from getting to the burners.
  3. If the LP tank contains gas, but there is no gas pressure at the burners or the burners will not light, follow the next 6 steps:
    • Make sure both control knobs on the Evo control panel are in the off position.
    • Make sure the LP tank valve is in the closed position by turning tank valve knob clock-wise to a complete stop.
    • Turn either one of the control panel knobs to the High position, and then back to the Off position. This bleeds the line.
    • Disengage the hose from the propane tank then screw back on. This will reset the regulator.
    • With both control panel knobs in the Off position, open the LP tank valve by turning the tank valve counter-clockwise to the full open position.
    • Turn one or both front panel control knobs to the Lite position and depress electronic igniter to start burner.

    Note: The process just explained is to reset the Marshall Gas regulator supplied with your Evo. The new safety features built into LP regulators are designed to prevent gas from being discharged in the event of a hose breakage. If there is no backpressure in the LP regulator hose, hence if the control valves are not in the Off position prior to opening the LP tank valve, the regulator is designed to shut down.

  4. If trouble persists, call you local Evo dealer or call Evo Customer Service at 866-626-1802.

My Evo was made to run on propane but I now have natural gas available outside, can I switch?

Yes! Evo outdoor models are available to run on either Propane (LP) or Natural Gas (NG). So if you ever want to switch, a simple conversion kit can be purchased to change from one gas type to the other (LP to NG, or NG to LP). Because the properties of these gases differ, the main change is to the jets within the gas valves – the orifices are different sizes. In addition the hoses and some connectors may change. A simple conversion process but still best left to a professional.
