Nexgrill Gourmet Pro 6-Burner Manual: A How-To Guide for Owners Who Already Built the Grill
Use the manual as an operating, care, and troubleshooting field guide - not just an assembly booklet. Steps, mistakes, and a seasonal checklist.

Your Gourmet Pro 6-Burner Is Built - Now Make the Manual Work for You
Most owners read the booklet once, during assembly, then file it in a drawer. That is a waste. The manual that shipped with your six-burner gas grill is the only document that describes the operating sequence, leak-test procedure, and troubleshooting matrix for the exact unit sitting on your patio. Once the frame is bolted together, the useful half of that booklet begins: how to light it in the correct burner order, how to configure a two-zone cook on three burners per side, and what to check when a burner stops lighting.
This guide treats the manual as a field reference for an already-built grill. It walks through six practical steps - confirming your revision, running the leak test at the start of the season, following the lighting order, setting up zones, inspecting burner tubes and heat tents, and working the troubleshooting matrix - then covers the maintenance cadence and part-sourcing path that keep a six-burner running for years. If your grill is still in pieces, this is not the article for you; go back to the assembly section.
The manual is written around a fuel system under pressure. Every step below assumes the gas supply is off and the lid is open before you begin. The CPSC's grilling safety guidance treats LP gas handling as the single most important thing a backyard cook controls.
What the Manual Actually Covers (It's More Than Assembly)
A typical Nexgrill gas grill manual runs 20 to 40 pages, and assembly generally occupies the middle third. The sections owners skip are the ones that matter after the frame is standing:
- Safety and leak-test pages near the front, including the soapy-water method and the warning against testing with a flame.
- Lighting instructions with a stated burner order and a match-lighting fallback for ignition failure.
- Cooking guidance covering preheat time, direct versus indirect zones, and lid position.
- Care and maintenance with a cleaning schedule and storage guidance for the LP cylinder.
- A troubleshooting matrix at the back, indexed by symptom - low flame, flashback, popping, no ignition.
- An exploded parts diagram with part numbers for burners, heat tents, igniters, and regulators.
That parts diagram is worth dog-earing now. In two or three seasons, when a heat tent rusts through or an electrode cracks, the diagram is far faster than a support call.
Prerequisites: Five Things to Gather Before You Open the Book
Set these out before you start, so you are not hunting mid-procedure: the manual itself, a spray bottle of soapy water (one part dish soap to three parts water), a flashlight for inspecting burner tubes, a screwdriver for removing heat tents, and a photo of your data plate. The data plate is typically on the inside of the cabinet door or the back panel, and it carries the model number (often a 720-xxxx or 810-xxxx string) plus the serial number. Write both down; every support interaction starts there.
Step 1: Confirm Which Manual Revision You Own - Once
Once You've Compared Two Options, Here's What Else Matters
Comparison shopping for a six-burner or its replacement parts gets you to a shortlist. What keeps the grill running is a maintenance cadence, a fast path to replacement parts, and knowing when a symptom is a fix and when it is a support call. The table and cadence below turn the manual's scattered guidance into a routine you can actually follow.
Symptom-to-Solution: A Gas-Specific Troubleshooting Decision Table
| Symptom | Likely cause | Manual-directed fix |
|---|---|---|
| Low or uneven flame | Low fuel, regulator flow-limit, blocked tube | Check cylinder level; reset regulator per manual; clear venturi |
| Popping or flashback | Blocked burner tube; burner misaligned on orifice | Turn off gas, cool, remove burner, clear and reseat |
| Ignition failure | Electrode gap, dead battery, wet igniter | Check battery; verify electrode spark; use match-light fallback |
| Hot spot on one side | Rusted-through heat tent | Replace tent; check exploded-view part number |
| Yellow flame, sooty smoke | Air-fuel mix off; partially blocked tube | Clear tube; confirm burner seated on orifice |
How Often Should You Do Each Maintenance Task? A Seasonal Cadence
Nexgrill manuals generally describe cleaning after each use and deeper checks at the start of the season. A workable cadence:
| Task | Frequency |
|---|---|
| Brush grates / empty grease tray | After each cook |
| Leak test at connections | Season start and after cylinder swap |
| Inspect and clear burner tubes | Season start; after any flashback |
| Check heat tents for rust-through | Season start |
| Deep-clean cook box and lid interior | Twice per season |
Parts and Exploded Views: Your Fastest Route to Replacement Burners, Tents, and Igniters
The exploded-view diagram at the back of the manual maps every component to a part number. When a tent or igniter fails, locate the number on the diagram, then order through support or the product pages at Nexgrill. Most six-burner grills accept a matched burner tube and heat tent set; verify the part against your data plate number rather than assuming a six-burner part is interchangeable across model years.
LP Cylinder Handling: Exchange vs. Refill, Storage, and the Regulator Vent
A standard 20 lb cylinder holds about 4.6 gallons of propane. Exchange (AmeriGas, Blue Rhino) runs roughly $20-$25 for a full cylinder in most U.S. markets, while a refill often costs $15-$20 and fills the cylinder more completely. For a six-burner used weekly, refilling at a local station is usually cheaper per gallon; exchanging wins when convenience matters more than cost. Store the cylinder upright, outdoors or in a ventilated space - never in a basement or hot garage; NFPA 58 governs storage, and the manual repeats it. Keep the regulator vent pointing downward so rain cannot enter.
Never store an LP cylinder indoors or in a hot car. The manual and NFPA 58 both treat it as a pressure vessel: heat raises pressure and can trigger the relief valve.
When to Stop Troubleshooting and Contact Support
Stop and call support when the leak does not resolve after one retightening, when the manifold itself is damaged, when a burner tube is cracked rather than blocked, or when the symptom persists across the matrix's top rows. Have your data plate photo, serial, and the symptom hand. Reach them through the contact page above.
A One-Page Seasonal Checklist You Can Run Each Spring
- Match data plate number to manual revision.
- Run the soapy-water leak test at every joint.
- Remove and clear each burner tube; check seating on the orifice.
- Inspect heat tents; replace any rust-through.
- Verify igniter battery and electrode spark.
- Deep-clean the cook box and lid interior.
- Confirm cylinder storage is outdoors and upright.
