About the Taylor Company C823-21
Taylor Company model C823-21 is a 24 in. gas griddle that meets ENERGY STAR requirements for commercial food service. Its T-1 steel plate measures about 24 in. wide by 24 in. deep, for a rated cooking surface of 4 sq. ft.
This is a conventional single-sided flat-top griddle, the workhorse for breakfast items, burgers, grilled sandwiches and sautéed vegetables cooked directly on the plate.
In standardized ASTM testing it achieved a cooking-energy efficiency of 46% and a production capacity of 31 lb of food per hour. Its efficiency beats 37% of the 31 gas griddle models in our database. Efficiency is the share of the energy consumed during cooking that ends up in the food; production capacity is how much product the plate can cook per hour at full load.
When the plate is hot but empty, it draws 2,257 Btu/h per sq. ft. of cooking surface, or about 9,028 Btu/h for the whole plate. That idle rate is lower than 64% of the 23 gas griddle models we list.

Safety information
- Install the griddle under a listed exhaust hood with grease filters and a fire-suppression system as required by your local code and NFPA 96. Griddles produce grease-laden vapor and must not be operated with the hood off.
- Keep the clearances to combustible and non-combustible construction shown on the data plate and in the installation manual.
- The plate, backsplash, grease trough and grease drawer get hot enough to cause severe burns. Use heat-resistant gloves and long-handled tools, and let the grease drawer cool before emptying it.
- Never use water on a grease fire. Shut off the heat source, activate the hood suppression system if needed, and use a Class K extinguisher.
- Do not flood a hot plate with cold water; sudden thermal shock can warp the plate and crack welds.
- If you smell gas, shut off the appliance supply valve, do not operate electrical switches or light any flame, ventilate the area and call your gas supplier from outside the building.
- Gas connections, conversions between natural gas and propane, and burner adjustments must be made by a qualified, licensed technician. Never test for leaks with a flame — use a soap solution or an electronic detector.
- If the griddle is on casters, secure it with a restraining cable and lock the casters so it cannot move away from its utility connections.
Installation and first-time setup
Plan the line position around the plate width of about 24 in., plus the side clearances in the installation manual. The hood must overhang the cooking surface on all open sides by the distance your code and hood manufacturer require.
- Check the utility match
Confirm the gas type on the data plate (natural gas or propane) matches your supply before connecting. Burner orifices and regulators differ between the two.
- Position and level
Set the griddle on a counter, stand or legs rated for its weight. Level the plate side to side and front to back with a spirit level on the cooking surface so grease flows evenly to the trough instead of pooling.
- Connect the gas supply
Use a commercial-grade gas connector of the correct size with a manual shut-off valve within reach. Leak-test every joint with soap solution, then have the technician verify the manifold pressure against the data plate.
- Clean the plate
Remove all packaging and any protective film or coating, then wash the plate with warm water and a mild detergent, rinse and dry it.
- Season the plate
A bare T-1 steel plate must be seasoned before first use. Heat it to about 350 °F, wipe on a thin film of high-smoke-point cooking oil, let it smoke off, wipe away the excess and repeat two or three times until the surface is evenly darkened.
- Verify the thermostats
Heat each zone to a known setting and check the plate temperature with a calibrated surface thermometer. Record the readings so you can spot drift later.
Using your griddle
Preheating and setting zones
Preheat only the zones you need and allow the plate to reach set temperature before loading — cold spots cause sticking and uneven color. Use separate zones for different products so a low-temperature egg area does not slow down a high-temperature burger zone. On a 24 in. plate, dedicate zones by menu item during rushes and turn unused zones down when business slows.
| Product | Typical plate temperature |
|---|---|
| Eggs (fried, scrambled) | 275–300 °F (135–150 °C) |
| Pancakes and French toast | 350–375 °F (175–190 °C) |
| Bacon and breakfast sausage | 325–350 °F (165–175 °C) |
| Burger patties | 350–375 °F (175–190 °C) |
| Grilled sandwiches | 325–350 °F (165–175 °C) |
| Searing steaks and chops | 375–400 °F (190–205 °C) |
Food safety on the griddle
- Verify internal temperatures with a calibrated probe thermometer: 155 °F (68 °C) for 17 seconds for ground beef and pork, 165 °F (74 °C) for poultry, and 145 °F (63 °C) for whole-muscle meats, fish and eggs cooked for immediate service (FDA Food Code).
- Keep raw and cooked products in separate zones and use separate spatulas and tongs for raw and ready-to-eat items.
- Hold cooked items at 135 °F (57 °C) or above until served, or cool them rapidly if they will be held cold.
- Scrape the plate between product types to prevent allergen cross-contact (for example, eggs or dairy-based items before plain proteins).
Saving energy during service
A griddle spends much of the day hot and waiting. Turning zones down or off during slow periods is the single biggest saving. This model idles at about 9,028 Btu/h with the whole plate on. Avoid running the plate at maximum setting when the menu does not need it.
Care and maintenance
| When | What to do |
|---|---|
| Between loads | Scrape food residue and grease into the trough so it does not carbonize on the plate. |
| Several times a shift | Empty the grease drawer before it is more than about half full. |
| End of each day | While the plate is warm, scrape it clean, use a griddle screen or stone to remove carbon, wipe it down, then apply a thin film of oil to protect the seasoning and prevent rust. |
| End of each day | Wash and dry the grease drawer, wipe the backsplash, side splashes and control panel, and clean the grease chute. |
| Monthly | Check plate temperature at each thermostat with a surface thermometer and have any zone that drifts more than about 10–15 °F recalibrated. |
| Every 6–12 months | Have a qualified technician inspect burners, pilots or igniters, gas valves and the flexible connector, and check combustion. |
| Per code (often semi-annually) | Have the hood, ductwork and fire-suppression system inspected and cleaned as required by NFPA 96 and your fire authority. |
Troubleshooting
Work through these checks before calling for service. Electronic controls display brand-specific fault codes; consult the code table in your manufacturer's manual for their meaning.
| Problem | Possible cause | What to try |
|---|---|---|
| Plate will not reach temperature | Supply valve partly closed; low gas pressure; thermostat out of calibration. | Open the valve fully; have the technician check inlet and manifold pressure and recalibrate the thermostat. |
| Hot or cold spots | Zones set differently; plate warped by thermal shock; overloading one area. | Map the plate with a surface thermometer; spread product across zones; replace a warped plate. |
| Food sticks to the plate | Seasoning worn away; plate too cool; carbon buildup. | Clean and re-season the plate; let it fully preheat before loading. |
| Excessive smoke | Carbonized grease on the plate; temperature set too high; hood fan off or filters clogged. | Scrape and clean the plate; lower the setting; clean hood filters and confirm the fan is running. |
| Grease overflows or pools | Grease drawer full; plate not level; trough or chute blocked. | Empty the drawer; re-level the griddle; clear the chute. |
| Temperature swings during a rush | Loading too much cold product at once; zone too small for the volume. | Stagger loads and spread product across more of the plate. |
| Pilot or burner will not stay lit | Draft from a fan or door; dirty pilot; faulty thermocouple or igniter. | Eliminate the draft; if the problem continues, have a technician service the pilot or ignition system. |
Energy use and running costs
At its rated idle input of about 9,028 Btu/h, every hour the Taylor Company C823-21 sits hot but empty costs roughly $0.14 at $1.50 per therm. If the plate idles for 6 hours of a 12-hour day, 312 days a year, that adds up to about 169 therms — $254 a year spent on standby heat alone.
During cooking, 46% of the energy the griddle consumes ends up in the food; the remaining 54% heats the plate edges, the kitchen and the exhaust air. A higher efficiency lowers the energy bill and the heat load your hood and air conditioning must remove.
Actual costs depend heavily on how many zones are on, the plate temperature, the menu and your local utility rates. Turning off unused zones during slow periods typically saves more than any other habit.
