Frequently Asked Questions

Will my grill hold up in the outdoor elements?

Yes. Viking outdoor grills are built from high-grade, corrosion-resistant stainless steel and are engineered to withstand harsh outdoor conditions. Each part undergoes special outdoor testing before certification, and control panel graphics are laser-etched to prevent fading or smudging. That said, regular cleaning and proper care, as outlined in the Use and Care manual, will extend the life and performance of your grill.

Can the grill be installed in an enclosed space?

No. This grill is designed strictly for outdoor use and must be set up in a well-ventilated area. It should never be installed or operated in enclosed locations such as garages, sheds, breezeways, or other buildings.

Why is my grill not getting hot enough?

A few common reasons include blocked burner ports or a faulty regulator. Make sure the burners are clean, check the orifices for blockages, and if running on natural gas, confirm that the conversion kit was installed correctly.

Why are the burners clicking but not lighting?

This issue may stem from moisture in the igniter after cleaning, dirty or misaligned burner caps, or a malfunctioning ignition switch. Ensure all components are dry, properly aligned, and free of debris.

How do I clean the grill grates?

Right after cooking, while the grates are still hot, brush them with a soft-bristle brush dipped in water. The steam will help loosen food residue. For a deeper clean, soak the grates, then wash with a mild detergent and a blue Scotch-Brite pad. Avoid harsh abrasives or steel wool, which can scratch the finish.

What’s the best way to clean the stainless steel?

For everyday cleaning, use warm, soapy water and a soft cloth, wiping along the grain of the steel. To remove smudges or fingerprints, occasionally use a stainless steel cleaner and polish—but not daily. Be sure to wipe up acidic spills immediately to avoid permanent staining.

What should I do if I smell gas?

Turn off the gas supply right away. Use a soap-and-water solution to check for leaks—never an open flame. If the odor continues, call a qualified technician to inspect the system.

The Pros and Cons

Pros

• Superior heat output and even cooking performance
  With powerful cast brass burners rated at 25,000 BTUs each and a ceramic briquette system, this grill ensures uniform heat distribution, reducing flare-ups and hot spots for consistently excellent results.
• Built for durability and long-term use
  The heavy-duty welded stainless steel construction resists rust and corrosion while eliminating gaps where grease and moisture can collect. This enhances the grill’s longevity and simplifies maintenance.
• Versatile rotisserie system for slow cooking perfection
  The dual-position rotisserie, combined with a high-powered 14,000 BTU infrared burner, allows for slow and even roasting, locking in moisture and flavor for juicy meats and poultry.
• Reliable and quick ignition system
  The hot surface ignition system eliminates the frustration of unreliable startups by providing consistent ignition at the push of a button, ensuring that the grill is always ready to use.
• Enhanced visibility for nighttime grilling
  Dual halogen grill lights illuminate the cooking area, making it easier to monitor food even in low-light conditions. The blue LED-lit controls add a premium aesthetic and improve nighttime usability.

Cons

• High fuel consumption due to powerful burners
  The combination of high-BTU burners and an infrared rotisserie burner results in greater fuel consumption, requiring frequent refueling for propane users or higher gas usage for natural gas setups.
• Premium pricing may not suit all budgets
  With its high-end materials and features, this grill is a premium investment. While it offers exceptional performance, it may not be the most cost-effective option for those with budget constraints.
• Built-in design limits portability
  Designed for permanent outdoor kitchen installations, this grill lacks mobility. Once installed, repositioning it requires significant effort and may involve professional assistance.
• Infrared rotisserie burner requires careful use
  The rear infrared burner produces intense heat, which may take some practice to master. Users need to adjust cooking techniques to avoid overcooking or burning food.
• Heavyweight build makes installation challenging
  The solid stainless steel construction adds durability but also increases the overall weight. Installation may require additional support structures and professional setup assistance.

Overall, this grill is designed for serious outdoor cooks who prioritize performance, durability, and premium features over portability and budget-friendliness. Its powerful burners, rotisserie system, and advanced ignition deliver exceptional cooking results, while the robust stainless steel build ensures it will stand the test of time. However, these benefits come with trade-offs: higher fuel consumption, a hefty price tag, and the need for professional installation due to its built-in, heavy-duty design. In short, this grill is best suited for those seeking a long-term, high-performance centerpiece for a dedicated outdoor kitchen rather than a portable or budget-conscious option.
