Sunstone Ruby 42″ Pro-Sear Grill with Infrared Rear Burner and Rotisserie
The Sunstone Ruby 42″ Pro-Sear is the largest Ruby gas grill, combining five main burners with a dedicated infrared rear burner and factory rotisserie system. It is intended for larger outdoor kitchens where the buyer wants multiple heat zones, broad grate space, and a separate rear heat source for rotisserie cooking.
Unlike the smaller standard Ruby configurations, the RUBY5BIR is built around the infrared/rotisserie package. It also carries the Ruby line’s 304 stainless steel construction, Pro-Sear cooking hardware, illuminated controls, interior grill lighting, service-access panel, and heat-riser/spill-away warming-grid design.

Installation & Ordering Notes
Order the LP or NG model to match the planned fuel supply. The Ruby 42″ also uses electrical power for the lighting and rotisserie systems, so utility access should be planned before the island is finished.
Follow Sunstone’s current instructions for self-rimming support, enclosure ventilation, combustible clearances, gas connections, leak testing, and wind exposure. Do not rely on nominal grill width when building the opening; use the manufacturer specification sheet.
