Many households have outdoor natural gas lines that can be used to fuel appliances like gas grills, fire pits, and more. This is an attractive solution for many people because it eliminates the worry of running out of propane in the middle of a cook because you are not limited to the amount of fuel a tank can carry.
Can I use my Traeger Flat Top Grill with Natural Gas?
The short and easy answer to this question is no, under no circumstances should a Traeger Flatrock Flat Top Grill be used with natural gas.
Traeger's Flat Top Grills are not certified to be used with natural gas. There has not been safety testing done for use of natural gas with our Flat Top grills. Traeger will not be liable if a Flatrock grill is used with natural gas.
The same is true for the use of a propane wall plug or large underground propane tank. The Flatrock is not certified to be used with any other fuel source than a standard 20lb propane tank and the use of such fuel sources would void the warranty. Traeger will not be liable for any damages or injuries incurred when using a fuel source other than the recommended propane tank.
What do you mean by 'not being certified to be used with natural gas'?
Appliances using gas fuel need to meet specific safety requirements to be sold for residential use. As explained above, the manifold on Traeger's Flat Top Grills is designed and certified for flow rates needed for propane gas but could not pass certification for the higher flow rates needed for natural gas.
Will modifying my Flatrock to use natural gas affect my grill's warranty?
Using a Traeger Flat Top Grill with a natural gas line, or any fuel source other than a standard 20 lb propane tank, will void the grill's warranty as it pertains to fuel management. Traeger will not be liable for any possible damages or injuries incurred as a result of a flat top grill being modified in any way including using natural gas as a fuel source.
Differences between using propane and natural gas?
Gas Power Density & Flow Rate: Propane gas has a higher power density (energy produced by volume) than natural gas. The Flatrock's gas management system, which includes the regulator, manifold, valves, and orifice is designed for propane.
Pressure: Traeger's Flat Top Grills use a regulator, which drops the tank's pressure to a level that is used in most gas appliances. An orifice at the end of the valve further restricts gas flow to target levels for the desired BTU output.
Residential natural gas is typically already regulated to levels that are compliant with appliances intended to be used with or converted to use natural gas.
