Fire Magic Built-In Insulating Liner - 3186-52
Product Description
The Fire Magic Built-In Insulating Liner (3186-52) is used when installing a Fire Magic A790 or E790 built-in grill in an enclosure made of combustible materials. It creates a protective liner inside the cutout while keeping the grill supported from the countertop.
This is the “plan it once” part. If your island is framed in wood or other combustible construction, the liner is what lets you build to the grill’s requirements without guessing your clearances.

FAQ
Q: What grills does the 3186-52 insulating liner fit?
A: It is listed for the Fire Magic A790 and E790 built-in grill series.
Q: Do I need this liner for a standard masonry or metal-stud island?
A: This liner is specifically for enclosures constructed of combustible materials. For non-combustible construction, follow the grill’s enclosure requirements instead.
Q: Can the liner be supported from below?
A: The liner is designed to be supported from the countertop using its hangers. Additional framing support may be used as allowed by the manufacturer.
Q: Where do the gas and electrical lines enter?
A: The liner has designated knockout openings at the front and rear for routing gas and electrical (when applicable).
Q: Do the liner ventilation openings matter if my island is already vented?
A: Yes. The liner ventilation ports must remain clear and should not be blocked.
Expert Installation & Performance Notes
For island planning, confirm the liner cutout dimensions before framing and before countertop work starts. The liner is intended for combustible enclosures, but the countertop must remain non-combustible.
Ventilation is not optional here. The liner’s ventilation openings must stay clear, and your enclosure still needs proper drainage and cross-venting per the grill manual.
Plan your gas run and any electrical feed path early so you can use the intended knockout locations instead of drilling after the island is finished.
