Napoleon 38″ Insulating Jacket for BIG38 700 Series — Frequently Asked Questions
What is the Napoleon 38″ Insulating Jacket?
The insulating jacket is a stainless steel, fully welded sleeve designed to surround the Napoleon BIG38 700 Series built-in gas grill when installed into cabinetry or combustible materials. It prevents high-heat transfer to surrounding surfaces and gives your outdoor kitchen a clean, built-in look.
Why do I need an insulating jacket?
When installing a built-in grill into wood or similar material, heat from the sides and bottom of the grill can damage or ignite the surrounding structure. The insulating jacket acts as a thermal barrier to block that heat transfer, improving safety and prolonging the life of your installation.
How is it constructed and what materials are used?
The jacket is made of stainless steel and is fully welded. This durable construction helps it resist corrosion and maintain rigidity under high heat.
How do I install the insulating jacket?
During the grill installation, slide the insulating jacket into the cutout or cavity first, then place the grill inside the jacket. Ensure the jacket is aligned, level, and flush with the cabinetry edges. The jacket should fully surround the grill in the opening to provide consistent insulation.
Does the insulating jacket affect grill performance?
No — the insulating jacket is passive and does not interact with burners, airflow, or cooking performance. Its sole function is to protect surrounding materials from heat radiation. Be sure ventilation and clearance requirements per the grill’s installation manual are still met.
What limitations or precautions should I consider?
You must use the jacket in installations involving combustible materials — it’s not necessary if your grill sits in non-combustible surfaces. Also, ensure that any necessary clearances specified in Napoleon’s installation guidelines are maintained (e.g. for ventilation, service access). The jacket should not be modified or cut, as doing so can compromise its insulating effectiveness.
