Description
The Blaze BLZ-PRO-IR is the infrared searing burner Blaze makes for its Professional LUX gas grills, such as the Professional LUX 34-inch grill (BLZ-3PRO) and the Professional LUX 44-inch grill (BLZ-4PRO). It puts out 18,000 BTU of infrared heat for searing steaks, pork chops and vegetables, and it takes the place of the grill's left-side standard burner.
Installation is a burner swap inside the firebox: the standard burner comes out, the infrared burner seats on the same gas valve, and the cooking grid goes back on. Blaze includes a spacer for grills where the burner does not sit down fully, and the metric Allen wrench used for the crossfire panel.
Plan before you order: Blaze allows one sear burner per grill, in the left-side position only. Installing more than one is not advised, can damage the grill, and is not covered by the Blaze warranty. For other Blaze grill series, Blaze makes the 14,000 BTU infrared searing burner (BLZ-IRN).
Features
- 18,000 BTU infrared burner: high, direct heat for a fast sear that locks in juices.
- Made for Professional LUX grills: Blaze designs it to replace the left-side standard burner on its Professional grills.
- Swap-in installation: seats on the existing gas valve stem and pins in place, with a spacer and Allen wrench in the box.
- Sear, then finish: sear thick cuts over the infrared zone, then move them to a standard burner on lower heat to finish.
- Self-cleaning routine: a 5-7 minute burn on high with the lid open after each use burns off residue.

What's included
- Infrared searing burner (BLZ-PRO-IR)
- Spacer, for grills where the burner does not lower fully onto the valve

Blaze does not publish part numbers for the spacer or wrench. The manual calls for needle-nose pliers and a new cotter pin to secure the burner; Blaze does not say whether a cotter pin is in the box.

Installation planning
- Remove the far-left cooking grid, flame stabilizing grid and heat zone divider.
- Take out the standard left burner: pull its cotter pin from the rear underside with needle-nose pliers and lift the burner out. Remove the crossfire panel by undoing the fastener beneath it with the included metric #4 Allen wrench.
- Seat the infrared burner the same way: the rear post goes into the chassis opening and the front venturi tube slides over the gas valve stem. It must sit correctly on the valve so gas flows safely; if it will not lower fully, add the included spacer. Secure it with a new cotter pin.
- Reinstall the heat zone divider and cooking grid, but do not put the flame stabilizing grid back over the infrared burner.
- Burn the new burner in on high for about 5 minutes, until it stops smoking. Some discoloration and slight flexing of the top mesh plate is normal.
- Install only one sear burner, in the left-side position. Blaze does not warranty damage to grills with more than one sear burner installed.
Use and care: Preheat the whole grill before cooking; if the grill is already hot, still run the infrared burner on high for 3 minutes before food goes over it. Do not pour marinade over food above the burner, because liquid can damage the plates or clog the gas ports. After each use, run it on high for 5-7 minutes with the lid open, then brush or vacuum off ash once the grill is cool. The ceramic tiles are fragile: avoid knocking the burner during installation, removal or storage.
Warranty
