The MOTAK Gas Range Manual describes a line of commercial gas ranges, including models with griddles, designed for professional cooking environments. These units are engineered for durability and low maintenance, meeting stringent industry standards.
Function Description:
The MOTAK gas ranges are commercial cooking appliances designed for high-volume use in non-residential settings. They feature multiple burners and an oven, with some models also incorporating a griddle. The top burners are manually controlled with individual pilot lights for reliable ignition. The oven includes a thermostat for temperature control, allowing for baking and roasting. Griddle models offer a flat cooking surface for frying, grilling, and other applications, with manual flame height adjustment for temperature control. The appliances are designed to operate on either natural gas or propane, with factory-set pressure regulators for each gas type.

Gas Pressure:
- Natural Gas: 4.0" W/C
- LPG (Propane): 10.0" W/C
The supplied gas pressure regulator is factory set for these pressures. A manual shut-off valve is required upstream from the manifold, within four feet (1.2M) of the appliance. The regulator can withstand a maximum pressure of 1½ PSI (14” WC); a step-down regulator is required if line pressure exceeds this limit.
Installation Requirements:
The appliance must be installed by a qualified installer in accordance with federal, state, and local codes, including National Fuel Gas Code ANSI-Z223.1/NFPA #54 (latest edition) and NFPA Standard #96 for Vapor Removal from Cooking Equipment. In Canada, CAN/CSA-B149.1 Natural Gas Installation and CAN/CSA-B149.2 Propane Installation Code apply. The unit requires proper ventilation and should be placed on a level, solid, nonflammable, nonskid surface. It is suitable for installation on non-combustible surfaces with zero clearance. The adjustable feet allow for one inch of height adjustment. A "drip leg" is recommended in-line before the regulator to prevent dirt or metal particles from damaging the gas valve.
Usage Features:
- Top Burners: Each burner has a pilot light for ignition. To operate, turn the valve knob counterclockwise to the desired flame height (Max or Min). After use, turn the knob clockwise to the origin position to shut off.
- Griddle Operation: Before first use, the griddle plate requires seasoning. This involves applying a thin film of high-quality cooking oil and heating the griddle at low flame for approximately 30 minutes, spreading the oil to prevent drying. This process is repeated 2-3 times, gradually increasing flame height, until a slick, mirror-like surface is achieved. The griddle is manually operated, meaning temperature is controlled by adjusting flame height, not by a thermostat. Preheating for 15-20 minutes is recommended before cooking.
- Oven Operation: The oven is ignited by pressing and rotating the thermostat knob counterclockwise, then lighting the pilot flame through an access hole. The knob must be held down for 20 seconds to heat the thermocouple. The oven temperature can be controlled between 250°F and 550°F. A "burn off" period at 450°F is recommended for first use to eliminate manufacturing odors and smoke. The oven thermostat has a by-pass setting that may need adjustment by a qualified technician during installation or gas type conversion to ensure a stable minimum flame.
Maintenance Features:
- Daily Cleaning:
- Body: Clean stainless steel surfaces with a non-abrasive cleaner and a soft cloth, wiping with the grain.
- Back and Side Splashes: Wipe with clean, warm mild soapy water, then re-wipe with a damp cloth.
- Controls: Wipe control knobs with a clean cloth to remove grease or debris.
- Griddle Plate: Clean with a grill pad or metal spatula. If necessary, use a griddle stone. Rub with the grain of the metal while warm. A mild soap can be used. After cleaning, cover with a thin film of oil to prevent rusting.
- Catch Tray: Remove and discard waste, grease, debris, and crumbs.
- Regular Cleaning:
- Burners and crumb trays should be cleaned regularly.
- Avoid abrasive detergents, brushes, scrapers, or chlorine cleansers on stainless steel surfaces to prevent rusting and damage.
- Do not spray water directly on the unit, especially when hot.
- Clean dirt off burners and baffles regularly.
- Ensure burner holes are not clogged to prevent incomplete combustion.
- Seasoning: The griddle must be re-seasoned after each cleaning with soap and water, as this removes the seasoning. For high-usage griddles, weekly cleaning procedures (including re-seasoning) may be done more often.
- Routine Inspection: Daily inspection is recommended to check for tilting, control panel damage, strange smells, vibration noises, abnormal burner flames (yellow tips, black soot, flashback, lifting flames), or gas leaks. Any issues should prompt immediate contact with professional technicians.
- Long-term Storage: If the device will not be used for a long period, turn off all gas valves, including the upstream supply valve.
- Disposal: 90% of the device is made of recyclable metals (stainless steel, iron, aluminum, galvanized metal sheet) and should be disposed of by an appointed treatment plant according to environmental standards.
Safety Precautions:
- Installation, operation, and maintenance must be performed by professional, qualified personnel.
- Keep flammable liquids and vapors away from the appliance.
- Do not obstruct combustion and ventilation air flow.
- Keep children away from the device.
- Do not use an open flame to check for gas leaks; use a gas leak detector or soapy water solution.
- In case of gas smell, immediately close the main gas valve, open windows for ventilation, and do not operate any electrical switches or phones.
- High surface temperatures can cause burns; do not touch the appliance directly during or after operation.
- Do not dismantle or self-modify the device, as this will void the warranty and can cause damage or danger.
- Ensure the gas supply type matches the device's setup.
- Do not use a gas type or regulator not applicable for the range.
- Do not leave the appliance unattended during operation.
- Do not obstruct the exhaust vent.
- Do not place flammable objects on the surface.
- Turn off the gas valve immediately after use.
The manual emphasizes that failure to comply with maintenance guidelines may void the warranty, and improper installation, adjustment, alteration, service, or maintenance can lead to property damage, injury, or death.
