What stands out
- Four Italy Sabaf burners with outputs of 10,300, 7,000, 7,000, and 4,000 BTUs.
- 0.03-inch 304 stainless steel integrally molded panel for stain resistance.
- Removable dishwasher-safe cast iron grates for easy cleaning.
- Thermocouple flameout protection (FFD) that cuts gas if the flame goes out.
- Factory-set for Natural Gas with included nozzles for LPG conversion.
Who it fits
Good fit for
You should consider this cooktop if you want high-output cooking in a standard 30-inch space. The 10,300-BTU burner is ideal for rapid boiling or searing. The sealed burners and smooth stainless steel surface make cleanup quick. If you prefer push-type rotary controls over digital interfaces, this design fits your preference. The built-in installation style works well for standard countertop replacements. The included thermocouple safety feature adds peace of mind for families.
Who should skip it
Skip this model if you need a built-in pressure regulator for LPG use, as the included regulator is for Natural Gas only. You might also look elsewhere if you prefer a digital display or electronic touch controls, as this unit uses manual rotary switches. The 1.67-inch height may not suit all under-cabinet clearances. If you require more than four burners, check the 36-inch or 30-inch 5-burner variations. The sealed design means you cannot access the burners from below.
Verdict: The Thermomate GHAF774 offers robust Sabaf burners and easy-to-clean stainless steel construction. It is a practical choice for those seeking high heat output in a built-in format.
Key specs explained for Thermomate
4 Burners
This unit includes four separate heating zones. You get one rapid burner at 10,300 BTU for quick boiling, two semi-rapid burners at 7,000 BTU for everyday frying, and one auxiliary burner at 4,000 BTU for gentle simmering. This mix lets you handle multiple dishes at once. If you often cook large family meals or need to keep sauces warm while searing proteins, this burner count and heat spread suits your workflow efficiently.
Sealed gas
The burners are sealed, meaning the gas delivery system is enclosed beneath the cooktop surface. This design prevents food spills and liquids from dripping into the internal components. It makes cleaning much simpler because you only need to wipe the flat stainless steel surface and wash the removable grates. For buyers who want to avoid scrubbing around complex grate structures or dealing with clogged ports, sealed burners offer a practical maintenance advantage.
NG/LPG convertible
The cooktop comes factory-set for Natural Gas but can be converted to use Liquefied Petroleum Gas using the included nozzles. This flexibility allows you to use the same unit regardless of your home fuel source, provided you have the correct regulator. Note that the included regulator is for Natural Gas only. If you live in an area with LPG availability or plan to switch fuel types, this feature saves you from buying a different appliance model.
120V
The unit requires a standard 120V AC electrical connection for its pulse ignition system. It includes a 3.9-foot power cord for easy connection to a nearby outlet. While the burners use gas, you still need electricity to generate the spark for ignition. This is a standard household voltage, so you likely do not need special wiring. Ensure you have an accessible outlet near the installation cutout to power the ignition reliably every time you cook.
Built-in
This cooktop is designed to be installed flush within your kitchen counter or cabinetry. The product size is 30 inches wide, but the required cutout is slightly smaller at 28.58 inches wide. This installation type provides a sleek, integrated look that matches modern kitchen aesthetics. You need to measure your cabinet space carefully before purchase. If you prefer a seamless countertop surface rather than a freestanding range, this built-in design fits your renovation or upgrade needs.
Build and Design Overview
According to the listing, this Thermomate unit measures 30 inches wide by 20.1 inches deep. The overall height is 1.67 inches, which fits standard under-counter cabinetry. You need a cutout space of 28.58 inches wide by 18.93 inches deep for installation. This built-in design requires precise countertop preparation. The cooktop sits flush with your counter surface, creating a streamlined look that integrates into your kitchen layout without protruding.
The surface is constructed from 0.03-inch #304 stainless steel. This grade of steel is resistant to stains and discoloration, helping the unit maintain a silver finish over time. The panel is integrally molded, which means there are no loose edges where debris can collect. You also get removable cast iron grates that are dishwasher safe. Sealed burners keep food residue away from the internal components, making routine cleaning faster and simpler.
Controls are handled via push-type rotary switches. These mechanical dials offer direct tactile feedback for adjusting flame intensity. The unit uses 120V AC pulse ignition, connected by a 3.9-foot power cord. This electrical requirement allows for easy spark generation without relying on batteries. The design prioritizes durability and straightforward maintenance, suitable for daily cooking tasks in a built-in kitchen setup.

Keep the 304 stainless steel surface clean to prevent staining. The removable cast iron grates are dishwasher safe, which simplifies daily maintenance.
