The Importance of Sizing and Regulating the Gas Pressures for High Performance Grills

I can’t stress enough the importance of sizing and regulating the gas pressures for the high performance grills that we offer at AOK. Just like high performance vehicles, they require the proper amount of fuel, pressure, and oxygen to function to MFG specs.

One of the biggest problems that we address in the field is the wrong gas pressure and volumes of gas being delivered to the grill. Typically symptoms are low heat (Low Pressure and or Volume), uneven heat (Restricted Oxygen) or extreme high heat ( High Pressure and Volume). Understanding how to size your pipe and pressure can be easy to solve since there are many charts and calculations to review, however, even the material the pipe is made with can make a big difference in the amount of gas delivered. Since many of the installations require the gas line to be buried the importance of the right material and size is critical.

AOK Tip: Total gas volumes are determined by adding all the gas volumes together of each appliance being installed. I suggest over sizing the line by as much as 80% or more to accommodate future appliances such as gas heaters, hot water heaters or additional appliances.

Use of a licensed Plumber is highly recommended to get the maximum performance from your Gas Appliances.


How to Purchase a BBQ Grill

How to Select a Barbecue Grill

Purchasing a barbecue grill in today’s market can be a challenging task, since there are over 60 different grill manufactures and many different price points. Budget can help dictate the final decision, but there are many others thing to consider such as: 1.) Construction Materials 2.) Fuel Type & Ignition Type 3.) Built-In or Cart 4.) Size 5.) Cooking Style 6.) Warranty – We will touch on each of these points to help you select the perfect grill:

1.) Construction Materials-

Judging by the name, you might assume that stainless steel never stains—but you’d be wrong. Stainless steel stains less easily than other iron-based metals, but it’s not literally “stainless”. Just like standard steel, stainless can get marked up by fingerprints and grease, develop discoloration, and eventually rust or pitting. The difference is resilience. Stainless steel can withstand much more time and abuse before showing signs of wear. Most of the luxury grills are made of Stainless Steel today. There are over 150 types of stainless steel out there, and there are 3-4 types that are commonly used. With this many different grades that are available it can be confusing, so knowing what to look for and what the differences are will help you decide and also determine your pricing.

304 Stainless Steel- 304 stainless steel is one of the most desired and widely used grades of stainless on the market. Type 304 stainless steel is a T 300 Series Austenitic Stainless Steel. It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. This alloy is extremely durable, as well as favorable for creating a beautiful finish. 304 is also one of the most expensive materials to manufacture so grills made with all 304 components will cost more. One test for 304 is it is non-magnetic.

316 Marine Grade- Marine grade 316 stainless steel is similar to Grade 304 with one notable exception. As well as chromium and nickel, Marine grade 316 also contains 2% to 3% of molybdenum, a hard, silver white metallic element used to toughen steels and increase corrosion-resistance in nickel alloys. The addition of this ingredient gives Marine grade 316 superior corrosion resistance to other chromium-nickel steels when exposed to chemical corrosives such as seawater and brine solutions. Unfortunately, it is mostly found in smaller boating or tailgating size grills.

443 Stainless Steel- Another common stainless steel is 443. It is a Ferrritic alloy that consists of Chromium and Titanium, while extremely low in Carbon. Together, these elements give 443 stainless a strong resistance to corrosion, especially against moisture and salt. Although most Ferritic alloys cannot compete with Austenitic alloys in terms of durability, the high level of Chromium in 443 makes it at least as corrosion-resistant as 304. Also, when compared to 304, 443 expands even less with heat, which means less stress and less warping. Remember, since 443 has high levels of Chromium, it is magnetic. This does NOT mean, however, that it is a low quality stainless! Even with a magnet on it, Chromium is one of the most corrosion-resistant metals around!

430 Stainless Steel- There are a lot of grills that use 430 Stainless Steel, it typically lowers that cost and durability of the grill. 430 which contains 17 percent chromium and 0.12 percent carbon contains more steel and is magnetic. The most important tip when buying a grill made of 430 is to look for a thick gauge and remember to clean your grill more frequently.

202 & 201 Stainless Steel- Some grills are also using 201 and 202 stainless, which has recently become very popular. Although they are Austenitic alloys, like 304, these alloys are not comparable to 304 in terms of durability and resistance to corrosion. They were created to cut the cost of Austenitic alloys by replacing most of the Nickel with Manganese or Nitrogen. The problem with this is that neither Manganese nor Nitrogen are nearly as resistant to corrosion as Nickel. So, although these alloys are NOT magnetic, they do not stand up to the elements nearly as well as 304 or 443. 201/202 is not very corrosion-resistant, especially under high temperatures, but low cost has made it more and more commonly used. Don’t let the magnet deceive you!

2.)Fuel-Ignition Type

There are many fuel types to choose from. You need to decide if you want charcoal, gas, logs, wood pellets, or electric. Also, there are some new hybrid multi-fuel grills showing up on the market today that offer unique cooking styles. Ignition Type? This can be important since many of the upgraded features on our grills will need 115 volts to function. Adding electric to an outdoor kitchen can be very expensive or even impossible in some situations. Battery ignitions have been more reliable over the years but are still prone to failures over time. Piezo ignition has been very reliable and we are starting to see this in even the more expensive grills. Piezo is like a Bic lighter, one turn, one spark, and it lights the burner, if it doesn’t light the first time repeat this process until the burner lights. Tip: We have added in our additional information tab for each appliance what type of ignition is used so that you don’t end up with the wrong grill.

3.) Built-In or Cart-

Built in grills- are made for installing into cabinets or islands that are typically in a permanent location. Since these grills are being installed in higher end cabinets made of stone, stainless steel or cement you will want to choose a grill that will last. Grills that are made of 304 grade Stainless Steel will last and look better than many of the other types of Stainless Steel offered today. Also, look for lifetime warranties on Burners, and the Firebox. Remember when purchasing a built in grill if the cabinet is not non-combustible the purchase of an Insulation Jacket will be required. Cart grills- allow the grill to be moved easily from one location to another and also can save some cost over constructing an outdoor kitchen. Many cart grills today will allow you to remove the grill head from the cart to build into an island at a later time.

4.) Size-

Is important, knowing how many people you want to cook for and if you like to cook meats, vegetables and entire meals on your grill will determine the size. Also, with the built in grills counter space is important, so keep in mind the scale of the grill in proportion to the countertops. Just like your main kitchen the countertops can fill up quickly. Size will also impact the budget so try to be realistic in your needs.

5.) Cooking Style(s)-

There are many manufactures that make grills today. Each grill has strengths and weaknesses, so knowing what style cooking is important to you and your lifestyle is very important. Make a list of the grilling styles that might interest you, such as: Searing, Smoking, Deep Frying, Rotisserie, Baking, Hibachi.


Most grill companies offer warranties and many of the grill companies have lifetime warranties on the burners, grates and stainless steel. Lifetime warranties on the burners and grates will keep you from having to spend money on parts. On gas grills, aluminum burners corrode and cast iron burners rust. You will want stainless steel or brass burners since they last longer any typically have a lifetime warranty. Also, Read the warranties since the stainless steel warranties only cover the functionality and not the finish.

Positioning a High Performance Built in BBQ Gas Grill

Building an Outdoor Kitchen will involve a lot of choices and decisions. Because the grill is permanent the position of the grill is important for looks, functionality and performance. Over the years we have encountered several grills that have been positioned in areas that are unprotected from strong prevailing trade winds that have done damage to the grill and also in extreme cases the structure.

The first consideration that we have when designing the outdoor kitchen is the grill location. It is important to ask or know if there is a prevailing trade wind. Since we supply a lot of grills to property owners that are located on the water there can be issues with strong winds. Wind can disrupt the grills ability to let the heat rise out the back of the grill when it is baking or indirect cooking mode.

Grilling Basics: Most people cook on grills with the grill hood in the (Indirect Cooking) closed position, this is the equivalent of an outdoor oven. Everything inside the grill is getting the same temperature and the food is cooking on the bottom and the top surfaces. In this style of cooking the heat inside the grill from the burners is rising and escaping out the back top of the hood. If there is a steady or strong breeze that is coming in towards the back of the grill the air pressure can push the hot air to one side of the hood or even worse push all the hot air down into the control panel. All grills are susceptible to this condition and it can cause damage to the electronics, gas valves or even the enclosure. You can tell if this condition exists if you are not getting the normal temperatures on the grill hood thermometer or if the control panel is getting warm or hot. Less expensive grills with small BTU burners will just blow out the flame, allowing the gas to continue to escape creating an explosive hazard. The more expensive grills with high BTU burners will continue to produce heat and can do damage to your grill or even the enclosure below.

The answer to this condition is to educate our customers and position the grill in a way that minimizes this condition. Also, the use of a large non-combustible backsplash behind the grill can also help block the grill from wind damage.

Second, you can cook with the hood open (Direct Cooking). Higher end grills have powerful BTU burners that produce more heat. This extra horsepower allows you to cook at different temperatures above each burner so you can cook meats, vegetables and fish on the same grill at the same time.

What is the difference between a $500 dollar grill and $5,000 grill?

One of the first questions I often get asked is “what is the difference between a $500.00 grill and $5,000.00 grill?

To answer this question I like to divide the grill market into 3 classes.

1.) The first class is the big box stores that offer grills in the 200-400.00 dollar range that are made of a thin gauge magnetic 418 or less Stainless Steel. These grills will cook well when new but over time (2 – 3 years) the grates and burners will fail. I myself have purchased a 300.00 grill and within the 2nd season was cooking over a ball of flame coming out one side of the burner. These grills are designed to be repurchased on frequent basis with no real brand loyalty. Warranty is usually one year on burners and often is hard to get replacement parts. Models numbers change frequently.

2.) The Second class is very interesting! These grills start about 400 and move beyond the 1,000.00 dollar mark, they cook well and offer a durable exterior and firebox with some good features. These grills can last 10+ years with some care and maintenance. The problem with these grills is again typically the burners and the grates. These grills are built for reoccurring revenue streams for repair parts. The grill exterior and firebox is still in good condition and the parts are priced enough below the original sticker price that some people will replace the parts rather than ditch the grill. Typical cost for replacement parts can be 300.00-600.00 for a new set of burners and grates. Warranty on the burners and grates is usually 3-5 years with most of the grills not getting registered within the 30 day period, therefore the warranty is sometimes void. Parts are easy to find and purchase. Most of these grills will have at least one replacement set of burners and grates or more before a decision is made to replace the grill. There is a good following of customers in this class that will buy the same brand.


3.) The Third class This class of grills will offer a lot of features that make sense in a permanent structure or heavily used environment. The grills are made of heavier gauge higher quality 304, 318 or 443 Stainless Steel. The burners and grates are made to last with a lifetime warranty and offer better control of high and lower temperatures. The prices typically start at 1,200.00and quickly go up past the 10,000.00 mark. Most of the lower price grills in this class are being imported and the higher priced grills are built in the USA.You will also find larger burners that produce 15-30,000 BTUs per burner giving you a hotter and faster temperature control. These grills are often the last grill that someone will purchase and offer the ultimate power and cooking experience.
