The spirit e 310 gas grill is a three-burner propane grill built for everyday backyard cooking, and this guide walks you through unpacking, assembling, leak-checking, lighting, preheating, cooking and cleaning it. By the end, you will know how to get the grill running safely on the first try, how to manage heat across its burners, and how to keep it working well for years. Manufacturer manuals for this model should always be your final reference for torque specs, gas pressure and warranty requirements.

What You Need Before You Start

Gather your tools and supplies before opening the box. Most owners find that a clear workspace and a helper for the lid and cart assembly save a lot of frustration.

  • Phillips and flat-head screwdrivers, plus the hardware and wrench included in the packaging
  • A full 20-pound propane cylinder with a valve that matches the regulator fitting
  • A spray bottle filled with a mix of dish soap and water for leak testing
  • A grill brush with stainless bristles or a non-metal scraper for cast-iron grates
  • A long-handled lighter or the grill’s electronic igniter, plus a backup match or lighter
  • A grill mat or drop cloth to protect the surface while you assemble

Step 1: Assemble the Grill Carefully

Assembly is the stage where most avoidable problems start, so take it slowly. Follow the numbered sequence in the manual, sort the hardware into labeled groups, and tighten fasteners snugly without over-torquing thin sheet-metal parts. Check that the lid hinges move freely and that the grease tray slides in and out without binding.

Check the Burner and Venturi Tubes

Before the burners go in, confirm that each burner tube sits over its venturi and that the venturi openings are clear of insects, packing debris or manufacturing dust. Blockages here can cause a weak flame or uneven heat. A flashlight makes this check much easier.

Install the Grates and Heat Components

Place the cooking grates and any flavorizer bars or heat shields exactly as the manual shows. Flavorizer bars sit above the burners and catch drippings, so an incorrect placement can lead to flare-ups or poor heat distribution.

Step 2: Connect and Leak-Test the Propane

A leak test takes about two minutes and is the single most important safety check you will do. Never test for gas leaks with an open flame.

  1. Make sure all control knobs are in the OFF position and the lid is open.
  2. Attach the regulator to the cylinder valve by hand, then tighten it with a wrench only as far as the fitting requires.
  3. Open the cylinder valve slowly.
  4. Mix a few squirts of dish soap with water and spray every connection point: the regulator fitting, the hose joints and each valve.
  5. Watch for bubbles. If bubbles form or grow, close the cylinder valve, tighten the connection, and test again.
  6. If a leak persists after tightening, replace the damaged part rather than forcing the connection.

Do not use the grill if you smell gas and cannot stop the leak. Close the cylinder valve, move away from the grill and contact your propane supplier or a qualified technician.

Step 3: Light and Preheat the Grill

Lighting the spirit e 310 gas grill follows the same logic as most three-burner propane models. Open the lid before you light anything, because gas can build up inside a closed grill and ignite dangerously.

  1. Open the lid fully and confirm the cylinder valve is open.
  2. Turn one burner knob to HIGH and press the igniter. If the burner does not light within about five seconds, turn the knob to OFF, wait several minutes for any gas to dissipate, and try again.
  3. Once the first burner is lit, repeat for the others as needed.
  4. Close the lid and preheat on HIGH for 10 to 15 minutes. Most cooks aim for about 500°F to 550°F for searing and 350°F to 400°F for general grilling, reading the built-in lid thermometer for a rough guide.

Use the Burners for Zone Cooking

Three independent burners make zone cooking easy. Keep one side on HIGH for searing and the other on LOW or MEDIUM for finishing, or leave one burner off entirely as an indirect zone. This approach works well for chicken thighs, bone-in pork chops and thick sausages, which need time to cook through without burning on the outside.

Step 4: Cook and Manage Heat

Good results come from controlling heat, not just setting the knobs and walking away. Use a separate instant-read thermometer for proteins, since built-in lid gauges can read differently from the grate-level temperature.

Food Burner Setup Target Internal Temperature
Chicken thighs (bone-in) Medium indirect, then sear over high 175°F to 185°F
Pork tenderloin Medium, lid closed 145°F with a 3-minute rest
Burgers High direct 160°F
Steaks (medium-rare) High direct, then reduce to medium 130°F to 135°F
Hot dogs and sausages Medium 160°F for fully cooked sausages

The USDA publishes safe minimum internal temperatures for poultry, pork, beef and ground meats, and those numbers should guide your targets above.

Step 5: Clean and Store the Grill

Clean the grates while they are still warm, using a stainless brush or a scraper suited to your grate material. Empty and wipe the grease tray regularly, since a full tray is a common source of flare-ups. Every few months, remove the flavorizer bars and burners to check for buildup and corrosion.

Disconnect the propane cylinder when you are finished cooking for the season or when storing the grill. Keep the cylinder outdoors and upright, away from heat sources. Cover the grill with a fitted cover that allows airflow so moisture does not collect inside.

Common Mistakes

  • Lighting with the lid closed. Unburned gas can pool inside the firebox. Always open the lid first.
  • Skipping the leak test. Loose fittings are common after shipping and storage, so test every time you reconnect the cylinder.
  • Ignoring the grease tray. A tray full of drippings is a fire risk and a source of bitter smoke.
  • Cooking at one heat level. Using all three burners on HIGH wastes fuel and makes it hard to control chicken and thick cuts.
  • Trusting the lid thermometer alone. Use an instant-read probe for meat, since lid readings are only a rough guide.
  • Storing the cylinder indoors. Propane cylinders should stay outside in a well-ventilated area.

Tips for Better Results

  • Preheat for the full 10 to 15 minutes, even when you are in a hurry. Grates that are cold will stick and steaks will not sear.
  • Oil the grates lightly with a high-smoke-point oil just before cooking, not on a cold grill.
  • Let meats rest for at least 5 minutes after pulling them off the heat so the juices redistribute.
  • Keep a spray bottle nearby for minor flare-ups, but close the lid first to starve the flame of oxygen.
  • Check the owner’s manual for the correct regulator type and any recommended maintenance intervals.

A few inexpensive accessories make the spirit e 310 gas grill easier to live with. Look for products designed for the grill’s dimensions, and confirm fit before buying.

  • Grill brush with stainless bristles helps clear grates quickly after cooking. Choose one with a sturdy handle and replaceable head. View on Amazon
  • Instant-read digital thermometer gives accurate internal temperatures for chicken, pork and steak, which the lid gauge cannot provide. View on Amazon
  • Fitted grill cover protects the grill from rain, dust and sun when it is not in use. Check that it fits the grill’s exact footprint. View on Amazon
  • Replacement drip pan liners make grease tray cleanup faster and reduce the risk of buildup. View on Amazon

FAQ

Can I use a 20-pound propane cylinder with the spirit e 310 gas grill?

Yes, a standard 20-pound propane cylinder is the typical fuel for this type of grill. Confirm the regulator and valve fittings match before connecting, and follow the manufacturer’s specifications.

How long should I preheat the grill before cooking?

Preheat for about 10 to 15 minutes with the lid closed. This gives the grates time to reach a stable temperature for searing and even cooking.

Why does one burner light more slowly than the others?

Slow ignition usually comes from a blocked venturi, debris in the burner tube, or a weak igniter. Clean the burner and venturi openings, and check the igniter electrode for a clean spark gap.

What should I do if I smell gas while the grill is off?

Close the cylinder valve immediately, move away from the grill and avoid any open flame or electrical switches nearby. Contact your propane supplier or a qualified technician before using the grill again.

How often should I clean the grease tray?

Empty and wipe the grease tray after heavy use, and at least every few cooks. A full tray increases flare-up risk and can attract pests.

Can I cook with the lid open?

You can, for short tasks like flipping food or checking progress, but keeping the lid closed holds heat steady and gives more consistent results.

How do I know when a steak is done without cutting into it?

Use an instant-read thermometer and check the internal temperature. Pull medium-rare steaks around 130°F to 135°F, then let them rest before slicing.

Should I consult a professional about gas safety?

Yes. If you suspect a persistent leak, a damaged regulator, or any gas odor you cannot resolve, contact a licensed propane technician or your local fire department for guidance.

Conclusion

Setting up, leak-testing and lighting your spirit e 310 gas grill correctly is the foundation for every good cook that follows. Once you have the routine down, the three burners give you flexible control for searing, indirect cooking and finishing. Keep the grates clean, empty the grease tray regularly, and you will get consistent results for seasons to come.
