Napoleon 18″ Insulating Jacket — Frequently Asked Questions
What is the Napoleon 18″ Insulating Jacket (Zero Clearance Liner)?
The 18″ Insulating Jacket (also called the “Zero Clearance Liner”) is a built-in accessory designed to safely isolate Napoleon’s 18″ drop-in burners (such as BIB18PB, BIB18IR, BIB18RT) from combustible materials in outdoor kitchen installations. It provides a heat barrier so you can place cabinetry or other materials closer to the burner without risk of heat damage.
What are its key features and specifications?
• Allows combustible materials to be installed adjacent to the burner without combustion or heat damage
• Designed specifically for Napoleon’s 18″ gas burners: BIB18PB, BIB18IR, BIB18RT
• Provides a safety “jacket” or insulating lining around the burner zones to control heat transfer
• Ideal for custom outdoor kitchen integration, ensuring both safety and aesthetic flexibility
How is it installed and used?
• The insulating jacket is installed around the burner box or housing as part of the drop-in burner setup.
• It forms a lining or shell that creates a thermal buffer between the burner and surrounding cabinetry or finish materials.
• It is used when you are building a custom outdoor kitchen and need to meet safe clearances but want to bring finishes closer to the burner.
• Always follow the manufacturer’s installation instructions and clearances when integrating this liner.
How do I maintain and care for it?
• Since it is a structural / safety component, maintenance is minimal under normal use.
• During periodic grill or burner servicing, inspect the jacket for warping, damage, or gaps.
• Ensure that no debris or grease buildup is bridging its insulating area to combustible surfaces.
• Re-seal or resecure any fasteners or seams if they loosen over time.
What are its advantages and limitations?
Advantages:
• Enables closer installation of combustible building materials while maintaining safety
• Helps integrate the burners into tight or custom outdoor kitchen designs
• Offers a consistent, factory-designed heat barrier solution
Limitations / cautions:
• Only compatible with Napoleon’s 18″ drop-in burner models (BIB18PB, BIB18IR, BIB18RT)
• It is not a cosmetic component — it must be installed correctly to function safely
• Misinstallation or damage may compromise its insulating effect, leading to heat transfer risks
