This manual provides essential instructions for the safe installation, operation, and maintenance of the Trufrost & Butler GDO series gas deck ovens. Key safety requirements include ensuring proper ventilation, using a low-pressure gas valve, and connecting the unit to a stable power supply with a voltage stabilizer. Never leave the appliance unattended while in use.
Product Overview
The GDO series ovens are commercial gas deck ovens designed for uniform heating. They feature digital temperature control, flameout protection, and tempered glass windows for monitoring food. Models are available in one, two, or three-deck configurations.
Installation and Safety
- Ventilation: The oven must be installed in a well-ventilated area. Keep the left and right sides at least 30cm away from combustible materials, and the back at least 50cm away.
- Gas Connection: Use only liquefied petroleum gas (LPG). A low-pressure regulating valve is required. Ensure all connections are firm and check for leaks using soap foam before initial use.
- Electrical: Connect to a 220V power supply with a leakage protection switch. The unit must be properly grounded. Use a voltage stabilizer to prevent damage from fluctuations.
- Placement: The oven must be placed on a level surface. Lock the casters to prevent movement.
Operation Instructions
First-time use: It is recommended to bake a plate of onions to remove any manufacturing odors before cooking food.
- Ensure all gas valves are closed.
- Connect the power and gas supply.
- Switch on the power and set the desired temperature using the digital controller.
- The pulse igniter will automatically ignite the burner. If ignition fails, wait 5 minutes before retrying to allow gas to dissipate.
- Adjust the damper if the flame is unstable or yellow.
- After baking, turn off the gas valve first, then the power.
Maintenance and Cleaning
- Clean the stainless steel surfaces regularly. Do not use water jets to rinse the oven.
- Clean the baking tray at least once a day.
- Inspect the gas cylinder, hose, and relief valve for damage or leaks regularly.
- If the oven is not in use, ensure it is turned off.
Troubleshooting
If the oven fails to ignite, check for igniter damage, solenoid valve issues, or incorrect ignition needle positioning. If the display shows "HHH", the temperature has exceeded the instrument range or there is a thermocouple issue. Always turn off the gas and power supply before performing any repairs.
Practical help
Common problems
Non-ignition
Check for igniter damage, solenoid valve failure, incorrect ignition needle position, or insufficient gas pressure. Ensure the fan is running and air intake is not too large.
Sudden flameout during work
Check if the gas cylinder is empty, the air intake is incorrect, or the igniter/solenoid valve is damaged.
Display shows 'HHH'
The temperature exceeds the range or there is a thermocouple issue. Check thermocouple wiring or replace the thermocouple/controller.
After ignition, the flame goes out
Adjust the induction needle position so it contacts the flame, or check for excessive wind.
Before use
- Ensure the gas source is liquefied petroleum gas (LPG).
- Verify the use of a low-pressure regulating valve.
- Check all gas connections for leaks using soap foam.
- Ensure the power supply is 220V and properly grounded.
- Confirm the oven is placed on a level surface and casters are locked.
- Ensure adequate ventilation and exhaust facilities are installed.
Specs in practice
- Gas Pressure
- 2.8 Kpa (Requires low-pressure valve).
- Temperature Control Range
- 0 to 400°C.
