Napoleon Insulating Liner for LEX485, P500 & PRO500 — Frequently Asked Questions

What is the Napoleon Insulating / Zero-Clearance Liner?

This is a stainless steel “zero clearance” liner (also called an insulating liner) built specifically for the **LEX485**, **Prestige P500**, and **PRO500** built-in gas grill heads. It enables you to install the grill head into a custom outdoor kitchen island using combustible materials closer to the unit—i.e. less clearance than normally required.

What are its dimensions and physical specs?

The liner is 10″ in height, 34.37″ in width, and 24.19″ in depth. It is constructed of durable stainless steel for long life in outdoor kitchen settings.

Which grill models is it compatible with?

It’s designed for Napoleon **LEX485**, **Prestige P500**, and **PRO500** built-in grill heads. It’s sometimes marketed under **BI-3323-ZCL** model designation.

What is the benefit of using a zero-clearance liner?

• It permits the use of combustible materials (e.g. wood framing or paneling) closer to the grill cut-out, reducing required buffer clearance. • Provides a safer, insulated barrier between high heat zones and adjacent structures. • Offers a clean, integrated look thanks to “seamless trim” design.

How do I install it properly?

Installation guidance (per manufacturer) suggests centering and fastening the liner flush inside your custom island frame before placing the grill head. Always follow documented instructions, ensure ventilation and gas clearances, and verify structural support. (Consult the product manual or Napoleon’s documentation.)

What is its warranty or return policy?

This liner is sold via Napoleon’s official channels and authorized dealers. The liner is typically covered by Napoleon’s limited warranty for parts, and return eligibility depends on retailer policy.
