You Have the Grill, the Box Is Open, and the Manual Is Gone - Now What?
You did the honest thing: you opened the carton on the driveway, sorted the hardware bag into a muffin tin, and then realized the printed assembly booklet went out with the recycling. The box is on the curb, the casters are rolling across the concrete, and your phone search for a Nexgrill 820-0063 manual is returning retail listings instead of instructions. This guide walks you through the sequence the printed booklet is built around, from staging the workspace through to the 15-minute burn-off, so you can keep building instead of waiting on a download.
One important correction up front: the 820-0063 is a model/part-family prefix, not a unique serial number. Nexgrill uses the 820-xxxx format to group related SKUs, which is exactly why a manual pulled by searching "820-0063 PDF" may describe a unit from a different production run in the same family. The instructions below follow the universal assembly order Nexgrill repeats across this grill category - cart and legs, firebox mount, side shelves and lid, cooking grates and heat tents, regulator and hose, burn-off - and flag the steps where the parts counter and support team see the most mistakes.
Not sure whether you need the full PDF or just a checklist? Section 3 gives you a five-minute decision tree that answers that before you pick up a screwdriver.
Before You Pick Up a Wrench: Confirm You Actually Have an 820-0063
Twelve minutes of identification saves a parts order placed for the wrong grill. The rating plate is the single source of truth here, and the "820-0063" on the retail listing is not it.
Reading the Rating Plate Like a Parts Counter Would
On Nexgrill gas grills in this family, the rating plate is a silver or white sticker with black print. You will find it in one of two places: on the rear face of the firebox, or inside the cabinet door. It carries the model number (which will begin 820-), the serial number, the gas type (propane or natural gas), and occasionally a short production code. When you call or email support, read the model number, serial, and gas type directly off the plate - do not paraphrase from memory or read from the marketing page you bought from, because those do not always match the physical unit.
Why 820-0063, 820-0061, and 820-0033 Are Not Interchangeable
The 820 family shares branding, not parts. The neighbouring 820-0061 and 820-0033 use different parts lists - cooking grates, burner tubes, and heat tents differ even when the photo on the box looks similar. Ordering a "Nexgrill 820 grate" without the exact suffix is how DIY fixes stall for two weeks. The safe rule: any part request must include the full suffix (820-0063) plus the callout number from the diagram, which we cover in the second half.
The Five-Minute Decision Tree: Do You Need the Full PDF at All?
When the One-Page Checklist Is Enough
If the hardware bag is intact, the lid, shelves, and grates are all present, and you have assembled a cart-style grill before, you almost certainly do not need the full booklet. The sequence below is repeatable and the torque values are forgiving. A taped-up one-page checklist (see the second half of this guide) covers you for assembly, leak test, and burn-off without a single PDF.
When You Genuinely Need the Model-Specific PDF
You need the actual document when: (a) a part arrived damaged or missing and you need to quote the diagram callout number, (b) your rating plate shows a build year that post-dates the last published revision you can find, or (c) you are converting between propane and natural gas, which requires model-approved orifice sizes. For those three cases, go through Nexgrill's support channel with your model, serial, and gas type rather than downloading the first PDF a search engine returns.
What to Stage Before You Start (Prerequisites and Workspace)
Tools, Tank, and the 6x6 Foot Rule
Budget ninety minutes to two hours for a first assembly, and stage the following before the first bolt:
- Cordless drill with a Phillips bit, or a Phillips screwdriver and an adjustable wrench
- Box cutter for the strapping and foam
- A spray bottle with soapy water (one part dish soap to three parts water) for the leak test
- A full propane tank, if the model runs on propane
- A second person for the firebox lift - the box is the heaviest single piece and the step most associated with back strain
Work in a clear 6x6 foot area on a hard, level surface. Cardboard from the carton is the ideal pad.
Why the Manual Warns Against Assembling on a Finished Deck
Grill manuals in this category specifically warn against assembling on a finished deck surface for two reasons. First, dropped fireboxes, casters, and lid panels damage wood and composite decking permanently. Second, the final step requires a burn-off at high temperature, which scorches anything underneath. Assemble on a driveway, patio slab, or garage floor, then roll the finished unit to the deck with someone steadying the front.
The Assembly Order the Manual Actually Uses
Step 1 - Cart and Leg Assembly (and the Caster Torque Trap)
Flip the cart panels upside down on your cardboard pad and bolt the legs to the side panels using the hardware bag's short bolts. Locking casters go on the front or the side the manual designates - not both on one end. The trap: overtightening the caster stems. Hand-tight plus a quarter turn is enough; crank them down and you deform the collar, and the caster stops swiveling. If a wheel seizes, back it off rather than forcing it.
Step 2 - Mounting the Firebox to the Cart
With the cart upright, two people lift the firebox onto the cart top and drop the mounting bolts through the flanges. Start every bolt by hand before you run any of them down with a driver. This is the alignment step - if the firebox holes and cart holes do not line up with finger-tight hardware, loosen the cart panel bolts a half turn, re-align, and re-tighten.
Step 3 - Side Shelves, Lid, and Handle
Side shelves bolt to the firebox sides, and their brackets often double as tool hooks. The lid hinges to the rear of the firebox; hold the lid open while you insert the hinge pins so the lid does not swing and pinch fingers. The handle is the last of this trio - the lid is heavy enough that a misaligned handle will pull the hinge out of square.
Step 4 - Heat Tents, Grates, and Warming Rack Orientation
Heat tents (the V-shaped metal deflectors) sit over each burner tube with the open side down, so grease drips past the burner rather than pooling on it. Flipped tents are one of the top three first-burn complaints - the symptom is flare-ups and a grill that runs hotter on one side. Drop the cooking grates and, if equipped, the warming rack after the tents are seated.
Step 5 - Regulator and Hose Connection at the Tank Collar
Thread the regulator onto the tank valve by hand only. Turn it clockwise until it seats, then stop - no wrench, no pliers. Cross-threading here is the single most common cause of a gas smell at first startup.
Step 6 - The 15-Minute Burn-Off Before Any Food Touches the Grates
Open the lid, turn all burners to high, and let the grill run for 15 minutes. Factory oils and residue burn off as visible smoke, then fade. Let the unit cool, brush the grates, and you are ready to cook.
Once you are clear on which manual route you need, comparing two specific models side by side can clarify whether you are assembling the right unit for your cooking habits. Try comparing two products side by side below to see which fits best:
Once You've Weighed the Two Paths, Here's What Else Matters
Choosing between the checklist route and the full PDF route changes what you need to know next. If you have been comparing two physical units - say your existing 820-0063 against a 4-burner with side burner from the current lineup - the differences that matter after the paperwork are the same: leak integrity, heat-tent orientation, and the parts you will inevitably need in year three. The five mistakes below account for the overwhelming majority of first-burn complaints on this grill category.
The Five Mistakes That Cause Most First-Burn Complaints
Skipping the Leak Test Because the Smell 'Seemed Fine'
The leak test is the step most often skipped and the one most often associated with incidents. Pressure the system by opening the tank valve with the burner knobs off, then spray soapy water at every connection - the regulator-to-tank collar, the regulator-to-hose crimp, and the hose-to-manifold fitting. Growing bubbles mean a leak. Tighten by hand, re-spray, and repeat. If the bubbles persist, stop and call support. The U.S. Fire Administration treats outdoor grilling fire safety as a leading seasonal home hazard, and most of those incidents trace back to gas connections that were never tested.
Cooking on Factory Oils Instead of Burning Off
New grates carry machining oils and a protective film. Cooking directly on them produces metallic off-flavors that rookies blame on the grill. The 15-minute high-heat burn-off with the lid open removes them completely.
Cross-Threading the Regulator at the Tank Collar
Hand-tight only. A wrench on a brass tank collar deforms the seat and guarantees a leak at the exact connection the leak test is designed to find.
Installing Heat Tents Upside Down
Open side down. Upside-down tents trap grease against the burner and cause flare-ups that look like a regulator problem but are not.
Storing the Unit With the Regulator Still Attached
Between cooks, disconnect the regulator and hose from the tank and cap the tank valve. Storing them connected lets the hose take a permanent set and stresses the regulator seat.
Two steps account for the majority of support calls: the leak test and the burn-off. Do both, every time a new connection is made.
Ordering the Right Part the First Time Using the Diagram Callout
Part names are hopelessly generic. The word "grate" describes four different cast iron and stainless steel products across the 820 family alone. The diagram callout number is the identifier the parts counter actually uses, and it is printed on the exploded diagram that ships with the manual or is provided by support.
| What you say | What the parts counter hears | What to give instead |
|---|---|---|
| "The grate" | Ambiguous - at least four candidates in the 820 family | Model suffix (820-0063), diagram callout number, size in inches |
| "The burner tube" | Length, diameter, and vent pattern all vary | Callout number plus measurement of the tube end to end |
| "The regulator" | Propane and natural gas use different assemblies | Gas type from rating plate + callout number |
Why 'Universal' Burner Tubes Usually Don't Fit the 820 Family
Aftermarket tubes marketed as universal are typically one length with slotted mounting holes, and they assume a common vent geometry the 820 family does not always share. Ordering the model-specific tube by callout number costs a little more and installs in one attempt.
How to Photograph the Rating Plate and Broken Part Together
When you request a replacement, take two photos in the same frame: the rating plate with the 820-0063 model number and serial clearly legible, and the broken part with the callout number visible or the diagram circled. Support cannot process a claim against a name alone, and a photo of the plate accelerates the match.
Matching Your PDF Revision Date to Your Build Date
How Nexgrill Revises Assembly Steps Across Production Runs
The manual is a living document. Between production runs, Nexgrill has revised hardware counts, hinge brackets, and regulator assemblies within the same nominal family. That is why a manual pulled from a 2019 listing can mislead an owner of a 2023-built unit - same prefix, different bolt layout.
Where to Find the Revision Date on the Back Cover
The revision date sits on the back cover, usually as a month and year. Compare that against the build date on the rating plate before you rely on the booklet. If the gap is more than two years, ask support for the revision that matches your build.
Printable One-Page Checklist to Tape Inside the Cabinet Door
Photocopy this list or write it on a card and tape it inside the cabinet door. It replaces the manual for routine assembly and covers everything the first-burn step needs.

What to Have Ready Before You Call or Email
Stop and contact support if the leak test bubbles persist after two hand-tightening passes, if the rating plate's gas type does not match the regulator you received, or if the hinge bracket holes will not align without force. Have these five items ready before you reach out: (1) model number and suffix from the plate, (2) serial number, (3) gas type, (4) the diagram callout number of any part you need, and (5) the photos of the plate and part taken together. Nexgrill's support team can confirm the correct revision of the manual and the exact parts list for your build. Do not guess on gas components - no parts-list shortcut is worth a leak.
