Product Summary
The Summerset Sizzler 40 is a 39 5/8-inch built-in gas grill for permanent outdoor kitchens. It uses five 12,000-BTU #304 stainless steel tube burners for 60,000 BTUs of total main-burner output and is offered as the SZR40 natural gas model or SZR40L liquid propane model.
This grill is best suited to buyers who want a large five-burner cooking platform, durable stainless steel components, straightforward controls, and operation without an electrical connection. It is not a portable grill and must be installed outdoors in a properly sized and ventilated enclosure.
Grilling Built Around Everyday Gatherings
Grilling is about creating moments that last. The Sizzler delivers commercial-grade performance in a sleek, dependable design that supports casual weeknight meals, weekend celebrations, and larger outdoor gatherings. Its five-burner layout provides the flexibility to cook multiple foods at different temperatures while maintaining a clean built-in appearance.
Durable stainless steel construction, thoughtful heat management, and responsive burner control help the Sizzler deliver reliable results without unnecessary complexity. The grill is designed to keep attention on the food while supporting the practical demands of a permanent outdoor kitchen.
Precision in Every Detail
Built for everyday outdoor cooking, the Sizzler 40 combines uniform heat distribution, precision airflow, and a practical five-burner layout. Whether preparing a quick dinner or cooking for a larger group, its independent burner controls allow the cooking surface to be divided into different temperature zones.
Five #304 stainless steel tube burners provide steady, responsive heat beneath #443 stainless steel flame tamers. The flame tamers help distribute burner heat and shield the burners from direct food drippings, while 8mm round cooking grates create a stable surface for routine grilling.

Cooking Performance
Five Independent Heat Zones
The five-burner configuration gives the cook greater control over heat distribution. All five burners can be used during preheating, while selected burners can be reduced or turned off afterward to create direct and indirect zones.
Stainless Steel Flame Tamers
Five flame tamers sit between the burners and cooking grates. They help distribute heat and reduce direct contact between the burners and food drippings.
8mm Round Cooking Grates
The removable 8mm grates provide a durable cooking surface and allow access to the burners and flame tamers for cleaning or compatible accessory installation.
Preheating Guidance
Ignite the main burners, close the hood, and preheat the grill for approximately 10 to 15 minutes. Once the desired preheat temperature is reached, turn off any burners that are not needed for the selected cooking method.
Built-In Installation Requirements
The Sizzler 40 must be installed outdoors in an enclosure constructed and ventilated for a gas appliance. Installation must comply with local codes and the instructions in the official manual.
Non-Combustible Island
The standard built-in opening must be constructed from non-combustible materials. Cement board with steel studs is recommended where appropriate.
Enclosure Ventilation
The enclosure must remain open to the outside or include the required ventilation openings. Do not block vents with storage items, doors, equipment, or landscaping.
Level Installation
The grill must be level in every direction. An out-of-level installation can cause uneven heating and erratic burner combustion.
Required Wall Clearances
| Non-combustible wall |
Maintain at least 2 inches from the right side, left side, and rear. |
| Protected combustible wall |
Maintain at least 10 inches from the right side, left side, and rear. |
| Unprotected combustible wall |
Maintain at least 14 inches from the right side, left side, and rear. |
| Combustible island surround |
A compatible Summerset insulating jacket or grill liner is required. |
| Overhead construction |
Maintain at least 5 feet between the countertop and overhead construction. |
Do not install beneath unprotected combustible overhead construction. Where an exhaust hood is required, follow the official manual and local installation requirements.
Outdoor Kitchen Ventilation Requirements
The enclosure must provide replacement air and ventilation. One side may remain fully open to the outside, or permanent ventilation openings must be provided.
- Provide at least four ventilation openings when the enclosure is not fully open.
- Each opening must provide at least 10 square inches of free area.
- The four openings must provide at least 40 square inches of total free area.
- Place two openings near the top of the enclosure.
- Place two openings near floor level.
- Space the openings at least 90 degrees apart.
- Keep all openings permanently unobstructed.
- Maintain the required clearance in front of and behind each opening.
Liquid propane is heavier than air, so low-level enclosure ventilation is especially important for an LP installation. Final ventilation must follow the appliance manual and applicable local codes.
Gas Supply Requirements
Natural Gas – SZR40
- Minimum inlet pressure: 4.0 inches water column
- Maximum inlet pressure: 7.0 inches water column
- Use the supplied natural gas regulator
- Size the gas line for the total connected BTU load
- Keep the gas-supply run as short as practical
Liquid Propane – SZR40L
- Minimum inlet pressure: 10.0 inches water column
- Maximum inlet pressure: 14.0 inches water column
- Use an approved LP regulator and hose assembly
- A standard 20-pound Type 1 propane cylinder may be used
- The propane cylinder is not included
Never connect an unregulated gas line directly to the grill. Failure to install the correct regulator can create a fire or injury hazard and may void warranty coverage.

Cleaning and Maintenance
After Each Use
- Allow food residue to burn off before brushing the grates clean.
- Turn every burner control to the OFF position.
- Close the main gas-supply valve.
- Allow the grill to cool and dry before installing a cover.
Exterior Stainless Steel
Clean the exterior with warm water, mild soap, and a microfiber towel or non-abrasive sponge. Wipe in the direction of the stainless steel grain, rinse thoroughly, and dry the surface.
Interior Cleaning
Periodically remove and clean the cooking grates, flame tamers, burners, and drip tray. Burner ports must remain open and free of grease, insects, nests, and other debris.
Coastal and Poolside Environments
Salt air and airborne chlorine can cause surface deposits, discoloration, or pitting. Clean the exterior frequently, allow the grill to dry, and protect it with a fitted cover when it is not in use.
Safety and Operating Requirements
- Use the grill outdoors only.
- Never use it in a garage, building, shed, boat, recreational vehicle, or enclosed area.
- Open the hood before lighting a burner.
- Do not leave the grill burning unattended.
- Keep children away during operation and until the grill has cooled.
- Keep gasoline, flammable liquids, and combustible materials away from the appliance.
- Keep an appropriate ABC fire extinguisher accessible.
- Test gas connections with a soap-and-water solution.
- Never test for gas leaks with an open flame.
- Have permanent gas piping installed by a qualified professional.
If gas is smelled, turn off the gas supply, extinguish open flames, open the hood, move away from the appliance, and contact the gas supplier or fire department when the odor continues.
