Restaurant Resource: How to Test for Gas Leaks in Your Kitchen
Gas leaks are serious—even small ones can endanger staff, customers, and equipment. Because some leaks are too subtle to smell, it’s essential to routinely test any restaurant equipment powered by natural gas. This guide covers two reliable testing methods, where to check, and what to do if you find a leak.
Why Regular Gas Leak Testing Matters
A few months ago, I found a natural gas leak in my basement. Watching the gas company test my appliances and lines made me realize how easily I could have prevented it. The same applies to restaurant kitchens: preventive testing can save time, money, and potential hazards—especially with ranges, ovens, and fryers that run on natural gas.
Two Ways to Test for a Gas Leak
1) Bubble Test
The bubble test is a classic, affordable method. Mix soap and water or use a commercial test solution (video demo) that clings to metal for easier detection.
Place the solution in a spray bottle or bowl.
Brush or spray it on pipes, fittings, and valves.
Watch closely—if bubbles form, you’ve found a leak.
2) Electronic Leak Detector
An electronic gas leak detector can identify even tiny leaks and is simple to use (many just require batteries). When gas is detected, an audio alarm will sound.
Where to Check for Leaks
Before you begin: Turn off the gas at the shut-off valve, then burn off any remaining gas from the stove.
Flex Pipe: The line connecting your range to the shut-off valve. Older ranges are especially prone to leaks here.
Cut-Off Valve: Inspect carefully around the valve’s shaft and joints.
Control Valves: Check the valves for each top burner, oven, and broiler.
Thermostatic Valve: Inspect the oven/broiler’s thermostatically controlled valve and all internal pipe connections.
Pilot Light Connections: For older ranges with pilot lights, examine all connection points thoroughly.
What to Do if You Find a Leak
Leaking cut-off valve: Call a professional to replace the valve.
Leaking flex pipe or burner/oven control valves: These components can typically be replaced using manufacturer-approved parts.
Internal piping issues: Contact your range manufacturer for the correct parts and instructions.
Key Takeaways
Not all gas leaks are detectable by smell—test routinely.
Use a bubble test or an electronic detector for quick results.
Start with the flex pipe and shut-off valve; inspect all control and thermostatic valves.
Call a pro for valve replacements or suspected major leaks.
Keep manuals and approved replacement parts on hand.
Recommended Next Steps
Schedule regular kitchen safety inspections.
Train staff on recognizing leaks and emergency procedures.
Keep make/model information accessible for swift parts sourcing.

Step-by-Step: How to Clean a Commercial Popcorn Machine
Step 1: Turn Off and Cool the Machine
Always unplug the popcorn machine and allow it to cool completely before cleaning. Give the unit at least 30 minutes to be safe. Kettles operate at high temperatures, and cleaning while hot can cause burns or damage components.
Step 2: Remove Loose Debris and Old Kernels
Empty any remaining popcorn, unpopped kernels, and debris from:
The cabinet interior
Warming deck
Crumb tray
Remove the crumb tray and set it aside for cleaning.
Step 3: Clean the Kettle
The kettle is the most important component to clean because it comes into direct contact with oil and food.
General kettle cleaning process:
Prepare a cleaning solution according to product instructions.
Pour the solution into the kettle.
Turn the kettle on briefly to warm the solution (if manufacturer guidelines allow).
Allow the solution to sit to loosen grease and carbon buildup.
Turn off power and allow the kettle to cool.
Carefully dispose of the solution.
Wipe the interior and exterior of the kettle with a soft cloth.
Repeat if heavy buildup remains.
Never immerse the kettle in water unless the manufacturer specifically allows it.
“The kettle is the most important part to keep clean because that’s where the popcorn is made. If buildup gets too heavy, it can affect how the kettle tilts, how components move, and even impact electrical parts over time. Keeping that area clean helps both performance and longevity.”
Bob Scharer Burkett Service Manager
Step 4: Clean the Cabinet and Glass
The cabinet collects oil residue and seasoning dust during operation.
To clean:
Wipe interior surfaces with a warm, damp cloth or approved cleaner.
Clean glass panels with a food-safe, ammonia-free glass cleaner to remove grease film.
Pay attention to corners and seams where oil residue can accumulate.
Avoid abrasive pads that may scratch surfaces.
Step 5: Clean the Crumb Tray and Accessories
Wash removable components such as:
Crumb trays
Scoops
Kernel trays
Doors or removable panels
Use warm water and mild detergent, then rinse and dry thoroughly before reinstalling.
Step 6: Reassemble and Dry
Allow all components to dry completely before reconnecting power. Moisture left inside the machine can affect electrical components or cause corrosion over time.
Once dry, reassemble the unit and return it to operation.
How to Deep Clean a Greasy Popcorn Kettle
In commercial environments, kettles may develop heavy grease or carbon buildup that requires deeper cleaning.
Signs a deep cleaning is needed:
Smoke during operation
Dark residue inside the kettle
Burnt odors
Uneven heating
Visible carbon deposits
Deep cleaning typically involves heating a manufacturer-approved cleaning solution in the kettle to loosen buildup. Multiple cleaning cycles may be necessary for heavily used machines.
Consistent routine cleaning helps reduce the need for intensive deep cleaning.
“Not cleaning the machine frequently enough is usually the biggest problem. When you stay consistent with cleaning, buildup doesn’t get the chance to harden and it’s much easier to maintain.”
Bob Scharer Burkett Service Manager

Outdoor seating has become an important part of many bars and restaurants, offering additional guest space while creating a relaxed and inviting atmosphere. Whether you are expanding your current footprint or designing a patio for the first time, the right combination of furniture, layout, and comfort features plays a major role in how successful the space will be.
Unlike indoor dining areas, outdoor patios must account for weather exposure, durability, traffic flow, and guest comfort in open environments. Choosing commercial-grade furniture and planning the layout carefully helps ensure your patio remains functional, comfortable, and visually appealing throughout the season.
This guide outlines key considerations for designing outdoor seating areas for bars and restaurants, including furniture selection, layout planning, and equipment that can enhance the overall guest experience.
Planning Your Outdoor Patio Space
Before selecting furniture, it is important to evaluate how the patio will function within your overall service environment. A well-planned layout helps staff move efficiently while creating a comfortable experience for guests.
Key planning considerations include:
Available Space and Capacity Measure the usable area and determine how many guests you want to accommodate. Consider walking paths, service stations, and clearance between tables to avoid overcrowding.
Traffic Flow Servers should be able to move easily between indoor and outdoor areas without obstacles. Clear pathways reduce delays and improve safety during busy service periods.
Accessibility Ensure seating arrangements allow for accessibility compliance and comfortable movement for all guests.
Shade and Weather Exposure Sun exposure, wind direction, and weather conditions influence furniture placement and comfort features. Planning for shade and protection early prevents adjustments later.
Utilities and Service Needs If you plan to offer outdoor beverage service, heaters, or lighting, consider electrical access and equipment placement during the planning phase.
Taking time to evaluate these factors helps create an outdoor space that supports both operational efficiency and guest satisfaction.
Choosing Commercial Patio Furniture
Furniture is the foundation of any outdoor seating area. Bars and restaurants require furniture designed specifically for commercial environments, where durability, stability, and ease of maintenance are essential.
Commercial patio furniture is typically constructed from materials that resist moisture, UV exposure, and temperature changes while maintaining structural integrity under frequent use. Investing in quality pieces helps reduce replacement costs and ensures a consistent appearance over time.
When selecting furniture, operators often consider:
Durability and weather resistance
Ease of cleaning and maintenance
Comfort for extended seating periods
Weight and stability in outdoor conditions
Storage flexibility during off-season months

Outdoor Patio Chairs and Seating Options
Seating plays a central role in guest comfort and overall patio functionality. The type of chairs you select should align with your service style, space limitations, and expected traffic volume.
Common seating options include:
Dining Chairs
Standard outdoor dining chairs are ideal for table service environments and can be arranged in various layouts depending on your capacity needs.
Stackable Chairs
Stackable seating provides flexibility for operators who need to store furniture during weather changes or seasonal transitions. These chairs are also useful for event spaces or patios with variable layouts.
Lightweight vs. Heavy Frames
Lighter chairs are easier for staff to move and rearrange, while heavier frames may offer additional stability in windy environments. The right balance depends on your location and usage patterns.
Bar-Height Seating and Outdoor Bar Stools
Bar-height seating can add variety to your patio layout while creating a more social and casual atmosphere. High-top tables and stools are especially popular in bar environments, breweries, and rooftop patios where guests may gather for drinks rather than full meals.
Bar stools designed for outdoor use typically feature weather-resistant materials and reinforced frames to withstand frequent movement and exposure. Selecting stools with footrests and supportive seating surfaces can improve comfort during longer visits.
Operators often incorporate bar-height seating:
Along railings or perimeter edges
Near outdoor beverage stations or bars
In lounge-style sections for social gatherings
To maximize seating capacity in smaller areas
Outdoor Tables and Table Tops
Tables serve as the functional centerpiece of patio dining areas. Selecting the right size, shape, and materials helps ensure durability while supporting efficient service.
Common considerations include:
Table Size and Configuration
Two-top, four-top, and communal tables allow flexibility depending on your guest mix and service style.
Table Materials
Commercial outdoor tables are often constructed from metal, resin, laminate, or composite materials designed to withstand weather exposure. Each material offers different advantages depending on your environment, budget, and maintenance preferences.
Metal (Steel or Aluminum)
Metal tables provide strong structural support and are widely used in commercial settings for their stability and long service life. Powder-coated or treated finishes help protect against corrosion and outdoor conditions. Heavier metal tables can offer improved stability in windy environments, though they may be more difficult for staff to move compared to lighter materials.
Resin and Polymer Materials
Resin and molded polymer tables resist moisture, stains, and fading while requiring minimal upkeep. These materials are often cost-effective and perform well in high-traffic environments. However, some resin products may show cosmetic wear over time with heavy commercial use compared to metal or laminate surfaces.
Replaceable Table Tops
Some systems allow table tops to be replaced independently from bases, extending the lifespan of your investment while allowing design updates over time.
Lounge Seating and Outdoor Chaise Options
Some patios benefit from more relaxed seating areas that encourage guests to stay longer and create a different atmosphere from traditional dining sections. Lounge-style furniture can be especially effective for rooftop bars, poolside service, breweries, or cocktail-focused concepts.
Outdoor chaise lounges and casual seating areas allow operators to create designated spaces for guests who may not be ordering full meals but still contribute to beverage sales and overall traffic.
Lounge seating works well for:
Rooftop or elevated patio environments
Poolside or resort-style service areas
Cocktail and social gathering zones
Waiting or overflow seating during busy periods
Durable construction and weather-resistant materials are especially important for lounge furniture since these pieces are often exposed to the sun for extended periods. Many bars and restaurants look for features such as UV-resistant construction, reinforced commercial-grade resin frames, or durable weather-resistant resin materials that help resist fading, cracking, and moisture damage while holding up to frequent outdoor use.
Shade Solutions: Umbrellas and Coverage
Providing shade is one of the most important factors for guest comfort in outdoor dining environments. Direct sunlight can quickly reduce how long customers are willing to remain seated, especially during warmer months.
Umbrellas offer a flexible and cost-effective way to improve comfort without permanent construction. Commercial-grade umbrellas are designed to withstand wind exposure, frequent repositioning, and extended outdoor use.
Key considerations when selecting umbrellas include:
Coverage area relative to table size
Stability and base weight
Ease of opening and closing mechanisms
Wind resistance and durability
UV protection for guests
Strategic placement of umbrellas can also help define seating zones and improve the visual appeal of the patio.
Extending the Season with Patio Heaters
Outdoor dining does not have to end when temperatures drop. Patio heaters allow bars and restaurants to extend seating use into cooler seasons, increasing revenue opportunities and maximizing the value of outdoor space.
Heaters are especially useful for:
Early spring and late fall service
Evening dining when temperatures decline
Regions with variable seasonal weather
Rooftop or open-air environments
Commercial patio heaters are designed to provide consistent heat output across seating areas while maintaining safety and durability in outdoor conditions.
6 Layout Tips for Your Restaurant Patio
A well-designed patio supports both guest comfort and staff efficiency. Poor layouts can create bottlenecks, slow service, and increase strain on employees during busy periods.
Helpful layout strategies include:
Maintain clear walking paths between tables
Position service stations near high-traffic seating areas
Allow enough space for chairs to move without blocking aisles
Separate dining and lounge zones when possible
Place bar-height seating along edges to maximize capacity
Keep entrances and exits unobstructed
Thoughtful furniture placement improves workflow while creating a more comfortable experience for guests.
When planning an outdoor patio, think about how servers will move between indoor and outdoor service areas during peak hours. Clear pathways, efficient table spacing, and accessible service points help reduce congestion and improve service speed.
Ingrid Gardner, CFSP
Durability and Maintenance Considerations
Outdoor furniture experiences more wear than indoor seating due to weather exposure, movement, and environmental conditions. Choosing commercial-grade materials helps reduce maintenance needs and extend product lifespan.
Routine care also plays a role in maintaining appearance and performance.
Simple maintenance practices include:
Cleaning surfaces regularly to remove dirt and debris
Storing or covering furniture during severe weather
Inspecting hardware and connections periodically
Drying cushions and surfaces after rain exposure
Stacking or storing furniture during off-season months
Like any commercial equipment, proper maintenance helps ensure long-term reliability and consistent appearance.
Creating an Outdoor Patio That Works for Your Business

Selecting durable furniture, planning efficient layouts, and incorporating comfort features such as shade and heating can help operators create inviting outdoor environments that support both service efficiency and customer satisfaction.
Whether you are building a new patio or upgrading an existing space, choosing commercial-grade furniture designed for outdoor use helps ensure long-term performance and flexibility. Exploring available patio furniture options can help you find solutions that align with your space, concept, and operational needs.
Why You See “NSF Certified” Everywhere in Commercial Kitchens
If you’ve ever shopped for commercial kitchen equipment, you’ve likely noticed the letters NSF showing up on ice machines, prep tables, shelving, sinks, and even smallwares. For many operators, it’s something they’ve been told to look for, especially when food safety and sanitation are top priorities.
But what does NSF actually mean? Let's find out.
At a Glance: What NSF Certification Means
NSF = National Sanitation Foundation - An independent organization that sets sanitation and safety standards for commercial foodservice equipment.
NSF certification focuses on sanitation, not performance - It evaluates materials, construction, and cleanability — not cooking power or speed.
NSF-certified equipment is easier to clean and sanitize - Designs reduce crevices, seams, and areas where bacteria can hide.
Often required by health departments - Many inspectors expect NSF-listed equipment in commercial kitchens.
Applies to more than just big equipment - Refrigeration, prep tables, sinks, shelving, and even smallwares can be NSF certified.
It’s a baseline standard, not a premium upgrade - NSF certification helps eliminate guesswork when choosing compliant equipment.
What Does NSF Stand For?
NSF stands for the National Sanitation Foundation.
NSF International grants NSF certifications. The name reflects NSF International's original focus: improving sanitation and public health through clear, measurable standards.
When you see a product labeled as NSF certified, it means that the equipment has been evaluated against specific sanitation and safety criteria. These certified products are designed to support clean and safe food handling in commercial environments.
Note: It’s also worth clearing up a common point of confusion. This NSF is not the same as the National Science Foundation (NSF), a U.S. government agency that funds scientific research.
Who is NSF International?
NSF International, a nonprofit entity, is dedicated to creating standards and certifying products, all to safeguard public health. Within the foodservice sector, their efforts center on verifying that equipment complies with sanitation and safety standards tailored for commercial use.
NSF International has been operating since 1944. They were originally founded as the National Sanitation Foundation(NSF), but have since expanded internationally. Today, they work with manufacturers, regulators, and industry professionals worldwide. This long-standing role and consistent oversight are why NSF is widely recognized and trusted throughout the foodservice industry.
NSF doesn't produce or sell equipment, nor does it endorse any particular brand. They function as an impartial third party, assessing products against predefined sanitation benchmarks. Manufacturers present their equipment for evaluation, and only those that satisfy NSF’s criteria earn certification.
“Manufacturers, regulators and consumers alike look to NSF International for the development of public health standards and certification that help protect the world's food, water, health and consumer products.”

What Does NSF Certification Mean in Foodservice?
In foodservice, NSF certification sets a consistent sanitation baseline for commercial kitchen equipment.
Rather than focusing on performance or features, NSF standards look at how equipment is built. That means the materials used, the type of surface finishes, and the overall construction. The goal is to reduce areas where food residue, moisture, or bacteria can collect.
For operators and buyers, NSF certification helps simplify equipment selection by providing a recognized standard across foodservice products.
