Why the label matters more on a grill
Grill parts look alike and fit very differently. Burners, heat plates, valves and igniter modules change between model years of the same series, and a part ordered from a photo is a gamble. Weber's own support team calls the serial number the single best tool for identifying a Weber gas grill, because the gas parts differ so much.
The label also answers the question of fuel. Lynx explains that the grill is set at the factory for propane or natural gas, that the regulator and orifices are tuned for the gas on the rating plate, and that checking the plate is how you confirm the match. A grill burning the wrong gas can light and still run lazy, sooty or dangerously high.
- Model number: the family, size and configuration.
- Serial number: the build, which decides the exact parts.
- Gas type: LP for propane, NG or NAT for natural gas.
- Heat input and, on some plates, orifice sizes and clearances.

Where the makers put it
Lynx names two homes for its plate: riveted beneath the drip tray, or fixed to the shield that sits behind the control panel. Its troubleshooting page adds that on a freestanding model the plate may be on the inside left panel of the cart, and that the back of the care and use manual carries a label with the model and serial number.
Blaze tells owners to look on the left-hand outside of the unit, and its manual repeats that the serial number sits on the outside left side of the firebox; on a head set into an island that side is hidden inside the cutout, so a photograph taken at install time is worth keeping. Weber says every gas grill has a serial number on a data label fixed to a component of the grill, with the exact spot depending on the model.
- Under the drip tray: Lynx built-in heads, and many others.
- Inside the cart, often the left panel: Lynx freestanding models.
- Outside left of the firebox: Blaze.
- On a component data label that varies by model: Weber.
- On the heat shield behind the knobs: Lynx, read at the visit.
What a Weber serial looks like
Weber explains that its gas grills have carried serial numbers since the first Genesis in 1985, starting with one or two letters followed by five to seven digits. If you find a string in that shape on a sticker inside the cart, you have found it.
Pellet grills and separate sear stations
A pellet grill carries electrical ratings as well as its model and serial, and makers tend to put the label on the back of the barrel, on the hopper or on the leg frame. A separate infrared sear station or side unit has its own label, and parts for it are ordered by its number, not the grill's.

When the print has faded or burned
Heat and grease darken a drip tray label, and sun bleaches one on a side panel. Wipe it with a dry cloth once the grill is cold, then photograph it with the flash on at a low angle; embossed or stamped plates often read better in the photo than by eye. A little stainless cleaner on a cloth lifts grease from a metal plate, but leave paper and foil stickers dry.
If it truly cannot be read, check the manual first. Napoleon's manual opens with a space to apply the serial number sticker, and Blaze's has a page for writing it down. A receipt, an installer's invoice or the maker's product registration may also carry the numbers.
The plate behind the knobs
Lynx's page mentions that the plate can sit on the heat shield behind the knobs and front panel. That panel covers the gas manifold, the valves and the igniter wiring, so if the drip tray and cart come up empty, leave the panel on and let the technician read it at the visit, bringing photos of the grill and its knobs instead.

Checking the label against the gas you burn
Once the label is found, compare its gas type with the fuel actually connected. A cart grill on a portable cylinder should say LP or propane. A grill on a hard pipe from the house should say NG or natural gas, unless the pipe comes from a large fixed propane tank. A mismatch after a move or a remodel explains a lot of lazy flames and sooty lids.
If they disagree, stop using the grill until it has been converted with the maker's kit. Conversion means changing orifices and setting the regulator, which is gas work and belongs to a technician, not a weekend project.
