About the Baxter Mfg. OV500G2EE

This guide covers the Baxter Mfg. OV500G2EE, a 30-pan gas rack oven listed as ENERGY STAR certified. It is classed as a floor or roll-in unit and holds 30 full-size sheet pans.

A rack oven bakes a full rack of sheet pans at once: the rack is rolled in, lifted and rotated during the bake so heat and airflow reach every pan evenly. Steam injection gives breads and rolls a crisp, glossy crust.

Under the ASTM test methods used for ENERGY STAR, it achieved a baking energy efficiency of 55% and a baking production capacity of 277 lb per hour. Its baking efficiency is higher than 50% of the 11 commercial oven ovens in our database.

Safety information

  • Have the oven installed and converted (natural gas or propane) only by a qualified gas installer, following the National Fuel Gas Code (NFPA 54) and local codes. Provide an accessible manual gas shut-off valve.
  • If the oven is on casters, connect it with a flexible connector certified for commercial cooking appliances and a restraining cable or chain so the gas line cannot be strained.
  • Check all gas connections with a soap solution after installation — never with a flame.
  • Connect the oven to an electrical supply matching the nameplate voltage and phase, installed by a licensed electrician with a means of disconnect. Switch off and lock out power before servicing.
  • Install the oven under an exhaust hood where required by your mechanical code and fire authority, and keep flue openings and vents clear.
  • Use dry oven mitts. Never load pans of hot liquid above eye level, where they can spill onto you when removed.
  • Make sure roll-in racks or trolleys are fully engaged and locked before closing the door, and treat racks as hot when removing them.

Installation and first-time setup

Commercial ovens must be installed by qualified gas, electrical and plumbing professionals according to the manufacturer's instructions and local codes. Dimensions and weights are not part of the certification data; take them from the specification sheet.

  1. Plan clearances and placement

    Position the oven with the clearances to combustible and noncombustible construction shown on the data plate and in the installation manual, leaving room to open the door fully and to service the controls.

  2. Level the oven

    Level the oven front to back and side to side. An out-of-level oven bakes unevenly and can affect door sealing.

  3. Connect gas

    Connect a gas line sized for the rated input of 275,000 Btu/h and the pressure on the data plate, with a sediment trap and manual shut-off valve. Confirm the oven is set up for the gas type supplied (natural gas or propane).

  4. Connect water for steam injection

    Connect treated potable water for the steam-injection system at the pressure specified, with a shut-off valve and backflow protection as required by code.

  5. Burn off and calibrate

    Before cooking, run the empty oven at a high setting for the time the manufacturer recommends to burn off protective oils, with the hood running. Then check the actual cavity temperature against the set point with an oven thermometer.

Using your oven

Preheating

In ENERGY STAR testing this oven preheated in about 13 minutes. Always preheat fully before loading; putting food into a cold cavity lengthens cook times and gives uneven results. Avoid preheating hours before service — turn the oven on only as early as your first bake requires.

Baking with a rack oven

  • Load the rack evenly, roll it in until it engages the lift or turntable, and close the door before starting the bake.
  • Use steam injection at the start of the bake for hearth breads and rolls; the system uses about 3 gallons of water per minute while injecting.
  • Allow the oven to recover to temperature between loads before rolling in the next rack.

Loading pans

  • Capacity is 30 full-size sheet pans.
  • Use pans that fit the oven's rack spacing and do not block the fan baffle or air channels.
  • Load all shelves of a batch at once and close the door quickly to minimize heat loss.

Food-safety temperatures

Based on the FDA Food Code. Verify with a calibrated probe thermometer.
FoodMinimum internal temperature
Poultry, stuffed foods and reheated leftovers for hot holding165 °F (74 °C)
Ground beef, pork and other ground meats155 °F (68 °C) for 17 seconds
Whole cuts of beef, pork, lamb; fish and seafood145 °F (63 °C) for 15 seconds
Hot holding after cooking135 °F (57 °C) or above

Managing idle time

Between batches this oven uses about 29,462 Btu/h at idle. Turn it down or off during long gaps between meal periods, and use any programmable shutdown or standby feature.

Care and maintenance

WhenWhat to do
DailyRemove racks and wipe the cavity once cool; clean spills before they carbonize. Wipe the door gasket and glass.
WeeklyRemove and clean racks, shelf supports and the fan guard; check the door gasket for cracks and the door for proper closing.
Per filter ratingReplace water filter cartridges when the gallon or time limit is reached.
MonthlyClean the cooling-air intake filter for the controls (if fitted) and check the core probe and its cable for damage.
QuarterlyCheck cavity temperature against the set point with an oven thermometer and have the controls recalibrated if they drift.
AnnuallyHave a qualified technician service the burners, ignition system and gas valve, check combustion and flue operation, and inspect electrical connections.

Troubleshooting

Work through these checks before calling for service. Allow the oven to cool before inspecting the cavity, fan or door.

ProblemPossible causeWhat to try
Food cooks unevenlyOven not level; pans blocking airflow; overloading; fan or element/burner fault.Level the oven; space pans and avoid oversized pans; reduce load size; call service if one area is always cold.
Long preheat or slow recoveryDoor gasket leaking; door opened frequently; failing element or burner; low gas pressure or wrong voltage.Inspect the gasket; limit door openings; have a technician check heat output and supply.
Temperature does not match the set pointSensor or control out of calibration; hood drawing too much heat; door not sealing.Verify with an oven thermometer; have the control recalibrated; check the door and gasket.
Smoke or burning odorGrease or food residue in the cavity; first use after installation.Clean the cavity and racks; complete the burn-off procedure on new ovens with ventilation running.
Error or service code on the displayA sensor, ignition, water or fan fault detected by the controller.Note the code and consult the code table in your manufacturer's manual before resetting; repeat codes need a service technician.
Oven will not igniteGas supply valve closed; power off to controls; ignition fault; burner lockout after repeated attempts.Open the gas valve and check power; follow the reset procedure in the manual once. If it fails again, call a technician.

Energy use and running costs

Baking energy efficiency is the share of the energy consumed that ends up in the food during a standardized ASTM baking test. At 55%, the Baxter Mfg. OV500G2EE delivers 55 Btu to the food for every 100 Btu it uses; gas ovens score lower than electric ones because some heat leaves through the flue.

Idling costs about $0.56 per hour at $0.17/kWh and $1.50/therm. If the oven sits hot but idle for 6 hours a day (1.56 therms + 6.06 kWh) and is preheated once daily, 365 days a year, standby and preheat energy alone come to roughly $1,523 per year — before any food is cooked.

Actual costs depend on menu, batch sizes, operating hours and how long the oven is left idling. Turning ovens off between meal periods is the simplest way to cut their energy use.
