Nexgrill 720-1046A Manual: Track Down the Right Revision and Read the Parts Page First

You Probably Need the Parts Page More Than the Assembly Page

If you are searching for the Nexgrill 720-1046A manual today, odds are you are not assembling a brand-new grill. You are trying to keep a legacy 720-series gas grill alive. That changes what you need from the document. The assembly script is already done - your grill is built, sitting on the patio, and something has failed. Maybe a burner tube is rusted through, a heat tent has warped, the igniter no longer clicks, or the regulator hose assembly is cracked. In that scenario, the exploded parts diagram with callout numbers is the page you will use most. The step-by-step assembly illustrations are secondary.

Nexgrill has been building outdoor cooking equipment since 1993 and sells widely through The Home Depot and nexgrill.com. The 720-1046A belongs to the company’s legacy gas-grill series, and like many grills in that family, it has been out of production for years. Replacement parts are still findable, but only if you match the exact revision. That is why the manual - and specifically the parts list inside it - is your best tool for ordering a burner that fits the first time.

What the 720-1046A Actually Is (and Why the Suffix Letter Decides Everything)

In Nexgrill’s numbering, “720-” is the legacy gas-grill series prefix. The string that follows - 1046A - is the SKU. The trailing letter is a revision marker. A 720-1046A and a 720-1046B can look identical from three feet away but use different burner tube lengths, different heat-tent angles, or a different valve-to-manifold fitment. That is not a hypothetical warning. It is the single most common reason a replacement part ordered for a 720-series grill arrives and does not fit.

Nexgrill has used revision letters (A, B, H, PG, and others) across the 720 series to denote production changes. When you search for a manual, the letter is part of the model identity, not a decoration. Treat “720-1046A” as a six-character string that must match exactly. If your rating plate says 720-1046, without a letter, photograph the plate and look for a separate revision sticker before you order anything.

Prerequisites: Five Things to Have in Hand Before You Open a Search Bar

A little staging saves a lot of wrong-part orders. Before you start hunting for the PDF, gather:

• A phone camera with enough light to read a small rating label.
• A tape measure or calipers for cross-checking part dimensions later.
• The exact model string from your grill, including any suffix letter.
• A notepad or a notes app for callout numbers and measurements.
• The serial number, if it is still legible - not because the manual needs it, but because Nexgrill support may ask for it when you escalate.

The manual itself typically does not print your serial number, so do not worry if the PDF asks for a model only. Serial numbers live on the grill, not in the document.

Step 1: Read the Rating Plate and Write Down Six Numbers

The rating label on a 720-series grill is usually inside the cabinet, on the firebox, or on the door frame. It is a small metallic or white sticker, and on a grill this age it may be greasy or faded. Wipe it gently and photograph it before you try to read it. From that plate, capture six data points: the full model string (720-1046A, letter included), the serial number, the fuel type (propane or natural gas), the BTU rating, the gas type/orifice marking if present, and the manufacture date or lot code. Those six numbers resolve almost every revision question. They also let Nexgrill support identify your unit without guesswork.

Step 2: Search the Exact String, Letter Included

Search engines handle “nexgrill-720-1046a-manual” inconsistently because hyphens and suffix letters get normalized. Run the string in quotes first: "720-1046A". If that returns irrelevant results, try "Nexgrill 720-1046A manual" without quotes. Avoid searching only “Nexgrill 720 manual” - that will surface every 720-series document and bury the one you need. The letter is the filter.

You can also search the Nexgrill site directly through the support and contact page, which is where legacy documentation requests are routed. Retailer product pages sometimes retain a “Manuals & Guides” tab even after a grill is discontinued, so check The Home Depot listing for the 720-1046A if a direct search stalls.

Step 3: Navigate to the PDF Through Brand Support or the Retailer’s Guides Tab

There is no single, permanent public URL for every legacy Nexgrill PDF. The reliable path is through the brand’s support channel or the retailer’s documentation tab. Start at the Nexgrill contact page and look for manual or parts requests; if a direct download is not listed, submit a request with your six rating-plate numbers. On the retail side, open the product page for your exact model and look for a “Manuals & Guides” or “Specifications” section. If neither path produces the PDF, a parts diagram for a closely related 720-series revision can still be useful - but only as a cross-reference, not as a fitment guarantee.

Try comparing two grills side by side below before you commit to a rebuild, especially if the parts total starts approaching the cost of a current model.

Once You’ve Weighed Repair Against Replacement, Here’s What Else Matters

A 720-1046A is old enough that a rebuild can be rational or irrational depending on which parts have failed. If you are replacing one burner tube and a heat tent, repair usually wins. If the firebox is rusted through, the cart is unstable, and the regulator, hose, igniter, and all four burners need replacement, the total can climb past the point where a new grill makes more sense. That is a judgment call, but the manual’s parts list gives you the numbers to make it with a calculator instead of a guess.

Which Consumables Actually Fail on a 720-1046A (and Roughly What They Cost)

The parts that fail on a legacy 720-series gas grill are predictable. Burner tubes rust from the inside out, heat tents warp and burn through, igniters lose their spark, and regulator/hose assemblies develop cracks at the fittings. The table below gives typical symptoms and rough U.S. price ranges for replacement parts. Treat the dollar figures as estimates - they vary by retailer and revision.

Add those ranges up for your failed parts before you order. A complete refresh of burners, tents, igniter, and regulator commonly lands in the $150-$250 range in parts alone, which is where the repair-versus-replace decision gets real.

Revision Letter Mismatches: The Mistake That Wastes the Most Money

The most expensive error in legacy-grill repair is ordering a part for the wrong suffix. A burner listed for a 720-1046B may have a different venturi position or tube length than your 720-1046A. The part will arrive, look close, and not seat correctly. You will pay return shipping and start over. The defense is simple: order by measurement, not by hope. Before you buy, measure the old burner tube’s length and width, note where the venturi opening sits relative to the valve, and compare those numbers to the parts diagram callout. If the seller cannot confirm those dimensions, do not order.

Leak-Test and First-Burn Procedure Once the Parts Are On

After any gas-part replacement, run a leak test before you light the grill. Mix soapy water, brush it on every connection - tank-to-regulator, regulator-to-manifold, and each valve fitting - and watch for bubbles. Never run a leak test with a flame. If bubbles appear, tighten the fitting and retest. Once the connections are clean, do a first burn with the lid open for the first few minutes to burn off manufacturing oils, then close the lid and bring the grill to cooking temperature.

1. Confirm all burner control knobs are off.
2. Connect the propane tank and open the valve slowly.
3. Apply soapy water to every gas connection and watch for bubbles.
4. Light one burner at a time and confirm a steady blue flame.
5. Run the grill empty for 10-15 minutes before the first cook.

Reading the Care Schedule Like a Legacy Owner, Not a New Buyer

A legacy grill needs more frequent inspection than a new one because the materials have already weathered. Read the manual’s care schedule as a minimum, not a target. Check burner tubes for rust every few months, not once a season. Inspect the regulator hose for cracks each time you swap the tank. Keep the firebox dry and covered. Those habits are what separate a 720-1046A that lasts another five years from one that fails in the middle of a cookout.

When the Manual Runs Out: Escalating to Nexgrill Support

If the PDF does not resolve your part, or your revision is not listed, go to Nexgrill’s contact page with your six rating-plate numbers and a photo of the failed part. Support can often identify the correct replacement even when the public document is incomplete. If the rebuild estimate climbs too high, a current Nexgrill model such as the 4-Burner Propane Gas Grill in Black with stainless main lid or the Oakford 875 Pro Pellet Smoker Grill may be the more economical path. Compare the parts total to a new grill before you commit to the rebuild.
