The Sunstone Ruby Pro Sear Gas Grill stands out in the premium outdoor cooking world, thanks to its all-304 stainless steel construction, exclusive fabricated I-burners (delivering high BTU output—up to 80,000+ BTUs on 4-burner models, plus optional IR sear burner reaching 1200°F), and the signature Pro Sear Thermal Cooking Grid. This innovative grid transfers heat with exceptional efficiency, achieving searing temperatures of up to 700°F with the hood open or 800°F with the hood closed—often in under 3 minutes from a single burner in some configurations. These features make the Ruby Series (available in 30" 3-burner, 36" 4-burner, 42" 5-burner models, with or without IR/rotisserie) ideal for restaurant-quality results at home, especially for steaks, burgers, and veggies that demand a perfect crust without overcooking the interior.
If you've ever dealt with uneven cooking, weak sear marks, or food sticking stubbornly to the grates, the culprit is often inadequate preheating. Preheating isn't just a suggestion—it's the foundation of great grilling on your Ruby Pro Sear. Here's a comprehensive, step-by-step guide to mastering the process, expanded with pro tips, safety notes, troubleshooting, and ways to leverage your grill's unique capabilities for the ultimate barbecue experience.
Why Preheating Is Non-Negotiable for Peak Performance
Preheating transforms your grill from a cold metal box into a precision cooking tool. Here's what it truly accomplishes:
- Even Heat Distribution — The Pro Sear grid and I-burners excel at rapid, uniform heating. Preheating ensures the entire cooking surface reaches consistent high temps, eliminating hot spots and cold zones that lead to patchy results.
- Superior Searing & Maillard Reaction — High initial heat caramelizes sugars and proteins on your food's surface (the Maillard reaction), creating those crave-worthy crusts, deep flavors, and classic diamond grill marks. Without it, food steams instead of sears.
- Non-Stick Magic — Hot grates cause food to release naturally once a crust forms. Cold or lukewarm grates? Expect tearing, sticking, and frustration.
- Food Safety & Cleanliness — Burning off leftover residue and bacteria from prior cooks keeps your grill hygienic and prevents off-flavors.
- Faster, More Efficient Cooking — Your Ruby heats blazingly fast (up to 150°F per minute in demos), so proper preheating gets you to cooking temp quickly without wasting fuel or time.
Skip or rush this step, and even premium features like variable rod spacing on the grids (wider for big items, tighter for small) or the built-in LED control panel lighting won't save your meal.
Safety First: Essential Warnings Before You Start
- Never leave the grill unattended during preheating—especially with 3+ burners on high. Stand nearby at all times.
- Always follow your model's Use & Care Guide (downloadable from sunstonemp.com) for lighting, gas type (LP or NG), and installation.
- Open the lid when first lighting burners to prevent gas buildup and flash fires.
- Perform a leak test on gas connections before each season.
- Keep children, pets, and flammables far away.
- Don't close the hood for extended periods (>3-5 minutes) on high with no food—risk of damage (not covered by warranty in some cases).
Step-by-Step: How to Preheat Your Ruby Pro Sear Grill
This process works across Ruby Series models. Time it right, and you'll hit ideal temps quickly.
- Prepare the Grill (2-5 minutes)
- Ensure the grill is clean: Remove grates if needed and brush off debris (do this while hot after previous use for easiest cleaning).
- Check fuel: Verify propane tank is full (or natural gas line connected properly) and regulator/ connections are secure.
- Open the hood fully for lighting safety.
- Set all control knobs to OFF.
- Light the Burners Safely
- Turn on the gas supply (tank valve or home line).
- Following your manual's lighting sequence: Push and turn the first knob to HIGH (hold in for ignition if electronic). Listen for the click/spark and flame.
- Light remaining burners one by one (counterclockwise usually). The flame-thrower ignition makes this reliable.
- If it doesn't light in 5 seconds, turn off, wait 5 minutes for gas to clear, and retry.
- Crank to Full Power & Close the Lid
- Set all burners (including any IR sear burner if equipped) to HIGH.
- Close the hood to trap heat—this accelerates preheating dramatically.
- Let it run undisturbed for 10-15 minutes (Sunstone's official recommendation). Many users hit searing temps in 8-12 minutes due to the efficient design.
- Verify Temperature
- Use a reliable grill thermometer (placed on the grates) or the built-in hood gauge.
- Target: 400-450°F for general grilling; 500°F+ for intense searing (Pro Sear grid shines here—push to 700-800°F hood position-dependent).
- Pro tip: For ultra-hot searing (steaks, chops), preheat longer (15+ minutes) or focus heat under the Pro Sear zone.
- Set Up Cooking Zones (Optional but Recommended)
- Once preheated, adjust burners: Turn some to medium/low/off for direct (hot sear) vs. indirect (gentle finish) zones.
- This two-zone setup is perfect for thick cuts: Sear over high heat, then move to indirect to reach internal doneness without burning.
Advanced Tips to Maintain & Optimize Preheat Temps
- Lid discipline — Keep it closed as much as possible during preheating and most cooking to hold heat (only open briefly to flip or check).
- Burner fine-tuning — Monitor and tweak knobs to hold your target temp. The Ruby's responsive controls make this easy.
- Regular maintenance — Clean grates/interior often for even heat flow. Brush while hot post-cook. Season stainless grids lightly with high-smoke-point oil if desired.
- First-time or seasonal startup — Follow the manual's checklist: Clear debris, confirm gas type/regulator, leak test.
- IR burner bonus (if equipped) — It reaches extreme temps fast—use for flash-searing, but preheat per manual (often hood open for IR).
- Weather adjustments — In cold/windy Austin conditions, add 2-5 extra minutes; shelter if possible.
- Avoid common pitfalls — Don't overcrowd during preheat (affects airflow), and never preheat with food already on—start clean and hot.
