Replacing an Outdoor Kitchen Burner: Cutout & Fit Checklist

A replacement burner must match the opening, enclosure and utility requirements—not just the old appliance's advertised width. Measure the finished opening before shortlisting. A smaller appliance may still need deeper clearance or a different support arrangement; a matching nominal size may require a different cutout.

Measure the opening, not the lid

Record width across the opening, front-to-back depth and usable height. Photograph the front, top and inside of the enclosure, plus the old model's rating plate. Note countertop thickness and overhang, obstructions, gas connections and nearby electrical access.

If an insulating jacket is installed, identify it separately. The new burner must be approved for that jacket; an appliance that physically fits inside an old jacket is not automatically a compatible replacement.

Two similar power burners, different openings

RCS RJCSB3A 14" × 19" × 8" An existing opening must have adequate depth and height.
RCS RSB3A 14" × 18-5/8" × 9-1/4" The same width does not make it a direct replacement for RJCSB3A.

Dimensions checked against RCS's current product specifications on October 8, 2026. These are bare-appliance openings, not liner openings. Confirm the drawing for the supplied model before fabrication.

Can you replace a side burner with a power burner?

Possibly, but compare more than width. Power burners may need different height, support, enclosure ventilation, approved cookware access and gas capacity. Upgrading from one pot of sauce to a large stockpot also changes the practical working position.

Have the installer assess added demand on the gas run. If the existing location lacks approved clearances or comfortable access to the intended cookware, a different location may make more sense than forcing the upgrade into the old hole.

What if the opening is too large?

A trim panel may conceal a gap without supporting the appliance. A custom support or adapter must meet the new manufacturer's installation requirements and preserve ventilation, connections, servicing access and clearances. Confirm how the appliance is intended to be supported before approving fabrication.

Send drawings and photographs for review. Do not order based on a promise that any gap can be covered; countertop material, structural support and enclosure construction determine what work is practical.

What if the opening is too small?

Compare the cost and feasibility of enlarging it with choosing a different burner. Countertop cutting and cabinet modifications can affect nearby components. Decide whether a required liner changes the opening before authorizing that work.

Replacement FAQs

Does matching the brand guarantee a fit?

No. Series and model generations can use different openings and jackets.

Does a liner let me ignore clearances?

No. An approved liner changes specified installation conditions; it does not cancel the rest of the manual.
