Usage Features
Installation:
- Requires two or more people for moving and installation due to weight.
- Grill drops into the enclosure and is supported by side flanges; no bottom support needed.
- Gas connections must be securely tightened and leak-tested.
- LP gas tank tray must be secured, allowing easy access to the tank valve. A cylinders baffler is recommended to prevent heat from the grill reaching the cylinder.
- NG conversion must be performed by a qualified installer/gas supplier according to manufacturer instructions and local codes.
Operation:
- Lighting the Grill:
- Ensure control knobs are OFF and hood is open.
- Slowly open the LP tank valve or manual shutoff valve for NG.
- Push in and turn the burner knob to IGNITE/HI.
- Manual lighting is possible using a match and the manual lighting extension if the igniter fails.
- If a burner does not light immediately, turn the knob to OFF, wait 5 minutes, and relight.
- LED Knob Lights:
- Power switch on the control panel must be ON.
- Requires 2 "AA" 1.5V batteries (user-purchased).
- Cooking Methods:
- Direct Heat: Food placed directly above lighted burners. Hood can be up or down. Searing is achieved with intense heat.
- Indirect Heat: Food placed above an unheated burner, with lighted burner(s) on either side. Cook with the hood down for shorter cooking times. Not recommended in windy conditions.
- Grilling Tips:
- Preheat grill on high for 10 minutes with the hood closed.
- Thaw food before grilling.
- Shorten preheat time for high-fat cuts to reduce flare-ups.
- Lightly oil grill grates or low-fat food.
- Trim excess fat from meats.
- Turn foods only once to retain juices.
- Avoid puncturing meats to test doneness.
- Adjust heat settings for long-cooking or sugary sauces.
- Add barbecue sauce only during the last 10 minutes of cooking.
- Rotisserie Burner (if applicable):
- Use a portable meat thermometer to check internal doneness.
- Turn off burner when meat thermometer reads 5°F/3°C lower than desired temp, continue rotating for 10 minutes.
Safety:
- Never store fuel tanks in a garage or indoors.
- Do not use the grill near combustible materials.
- Do not store combustible materials near the grill.
- Ensure proper ventilation of the cylinder enclosure.
- Inspect gas supply hose before each use; replace if worn or cut.
- Turn off gas at the supply cylinder when the grill is not in use.
- Storage of the grill indoors is only permissible if the cylinder is disconnected and removed.
- Cylinders must be stored outdoors, out of reach of children, and not in enclosed areas.
- Never fill LP cylinder beyond 80 percent full.
- Do not let food sit for more than one hour before or after cooking to prevent food poisoning.
- If gas odor is detected, shut off gas, extinguish flames, open lid, and call gas supplier/fire department.
- In Massachusetts, installations and repairs must be performed by a qualified or licensed contractor, plumber, or gas fitter.

Stainless Steel Surfaces (Exterior):
- Rub in the direction of the grain to avoid scratching.
- Use stainless steel cleaner, liquid detergent, or all-purpose cleaner.
- Rinse with clean, warm water and wipe dry with a soft cloth.

Burners:
- Clean the exterior with a wire brush.
- Clear clogged burner ports with a straightened paper clip (do not use a toothpick).
- Check and clean burner/venturi tubes for insects and debris.
