There are a number of factors that can contribute to low heat. We highly recommended that you hire a licensed plumber to set up the gas lines and connections. Rule of thumb, you should experience approximately 1 1/2" high flame. The heat should go to 500 degrees F with the lid closed, all burners on, except for the back rotisserie sear burner within 15 minutes.
Factors that affect the maximum heat can be some of the following but not limited to:
- The length of the gas line,
- Incoming Gas pressure measured in water columns.
- 4-7 water column pressure (approx .25 PSI) for Natural Gas and
- 11 water column pressure (approx .39 PSI) for LP or Liquid Propane
- Gas line Diameter or Volume will affect the grills performance. Assuming all lines and connections are configured to provide adequate pressure, there are other factors which may cause your grill not to get hot enough gas volume.
** Side note - More and more houses are adding more natural gas consumption, pools heaters, firepits, 2nd water heaters, larger stoves, Your plumber or professional should have calculated all the items running at once to make sure each gas appliance gets the correct amount of gas.
Check to make sure the burner is on the high setting. The low setting is when the knob is all the way to the left. Moving the dial to the right increases the flame height.
Regulator clogs or running gas through multiple regulators could decrease the pressure not allowing your grill to heat to the proper temperature. Replace if your gas flame has lowered that you are used to seeing or that it is not at approximately 1 1/2" high.
NG (Natural Gas) vs LP (Liquid Propane) Gas
Running natural gas into an LP or liquid propane set up, will result in a very low flame and low heat.
Make sure the Natural Gas Regulator nut is set for Natural Gas, which you will see in your manual or some of our instructional videos. Some Natural Gas regulators are not convertable and will need to be removed to run LP or Liquid propane. The orifice size of an LP set is smaller than an NG and may not be allowing enough gas through.
