(Frequently Asked Questions)

The answers to the most common questions


  • The double drawer refrigerator is not frost free, you will need to turn it off and let any build up defrost, usually a few times a year. The drawer not shutting all the way is due to the ice buildup on the back of the unit.
  • Turn the griddle on and let it burn off the oils from manufacturing, for a good 20 minutes. Use a good quality high temp cooking oil to season the griddle before cooking. After cooking you can use warm water to spray on the griddle and scrape any food off. Re season with oil and it will be ready to use for next time. We recommend using a long glove to keep your hand/arm safe from heat while cleaning.
  • Bull grills have high BTU’s, and it takes some time to learn how to cook on one. We suggest always letting the grill get hot, then turning it down to low to cook.
  • This is often due to a small fire inside the burner when lit. Turn the burner off and re-light. This can also happen if the NG gas line used to supply your grill is too small or they are installed with quick connect fittings that often restrict gas flow, check with a plumber to make sure gas connections are the appropriate size.
  • Moisture is the culprit most likely due to weather conditions and humidity. You can take it off and take it apart to dry the inside out and it should be back to normal.
  • It’s possible that wind is entering through the back of the grill and forcing the heat back towards the knobs, not usually controllable. Another possibility is that there could be a fire in the burners or near the valves that isn’t seen.
  • It’s possible that the burner wasn’t installed correctly. The burner must be seated properly over the valve and the tab on the back is inside the hole. The knob will need to be pushed down for a good 7-10 seconds to push gas into the burner, before lighting. You will also want to inspect the burner for any cracks in the ceramic, if there are, the burner needs to be replaced.
  • The most common reason grills catch fire, are due to the drip tray not being cleaned or maintained. The drip tray should be cleaned often, we sell liners that you can use on the tray to trap grease, when its full, simply toss it in the trash.
  • Gas leaks are another big reason for grill fires. Which makes ventilation a major necessity when building outdoor kitchens. If the gas has nowhere to escape during a leak, it’s possible it could cause an explosion if someone tried to re light a grill or use a match.
  • Our Piezo ignition systems work in 2 stages. Push the knob in, gas will begin to flow into the valve and then creates one spark to light. This process is quick. There are times that these valves will freeze up, if they aren’t turning or lighting, its time for a replacement. Remember to always make sure that the black rubber gasket Is on the valve correctly to prevent gas leaks.
  • Note: Use Teflon tape on all threaded connections.
  • Connect a short double ended 3/8 female flare gas line to the back of the BBQ. Then connect a 3/8 Flare “T” Fitting to the gas line. From that connection, you will have two remaining access points. One for the side burner and one for the Incoming gas. Make your connections and light it up.
  • Make sure the gas is on. Turn the knob slowly but stop before the ignition snaps, when you stop, hold the knob for 7-10 seconds. This allows the gas to flow through the Infrared Backburner for 7-10 seconds allowing the gas to migrate to the opposite side of the Backburner where the ignition is located. After doing so proceed turning the knob to complete the snap. Once you hear the snap the gas will be ignited.
  • Weather and propane tank supply is a factor. If your tank is low and its cold out, the grill won’t get to the 500-600 range as it would if the outside weather was warmer and/or if the tank was full.
  • Our grills are made with stainless steel that contains nickel. Neither are rust proof. Living near the ocean or having a saltwater pool that will splash on the stainless, could eventually lead to rust. We recommend using rust removal cleaners on your stainless that will aid in getting rid of the rust and preventing it from forming again. There are also products on the market that can be applied to stainless steel and act as a coating to help prevent rust. Certain pool chemicals and or cleaners can also discolor or lead to rust on stainless. Always be careful with products used near your Bull equipment.
  • We’ve redesigned our flame tamers with “ReliaBULL” technology, which has smaller vents on the back, to reduce cold spots from happening in the front of the grill. While we strive for 100% heat distribution, many factors can hinder that from happening on occasion.
  • Because of the location of the backburner, it will take longer for gas to reach the burner. Push and hold the knob in for 8-10 seconds before igniting.
  • Bull currently does not cut any holes for drainage, but when your plumber hooks up the gas to the burner you have to drill a hole into the cement board in order to get to the burner. So that provides an out for water.
  • A good test is to mix a bit of water with dish soap. Then with a brush dab your connections with the soapy water, if you do indeed have a leak you will see your connection start to bubble.
  • Needs some cleaning! Take the burners out, remove the cotter pins that are behind and beneath the BBQ and shake them or air gun them and get all the dirt out of the burners. Keep in mind that if your burners are bowed it is time for new ones.
    If your grill is brand new out the box and you’re running L.P gas, then you might have a N.G Unit.
  • Check the line. There is a chance that there is foam at the entrance of your gas line located in the back right corner of the grill. You might have a fouled regulator. There might be a gas leak plugging your regulator for safety.
  • Regulator might be restricting too much gas.
  • Valve might need replacing. Regulator might be restricting too much gas.
  • Burners either need to be cleaned, or there is something disturbing the flow of the gas making the gas travel back towards the valve and with the ignition igniting the gas you are getting fire right by the knobs.
  • Check all connections to the grill. If there are no leaks then there is a chance that there is actually a leak right underneath the grill. To check it is easy, get in front of the grill and look at the valves from underneath. There is one screw that holds each valve into place. Tighten each one snuggly, this should be the solution.
  • 99% of the time Valves need to be replaced, the ignitions system has failed.
