This manual provides essential instructions for the installation, operation, and maintenance of Avantco 177CAG series commercial cooking equipment. Before use, ensure the unit is installed by a qualified professional, the gas type is compatible, and all protective films are removed. Regular maintenance and proper cleaning are critical for equipment longevity and safety.

Safety Information
- Installation must conform to local codes or the National Fuel Gas Code (ANSI Z223.1).
- Always use certified hoses and pressure regulators.
- Do not obstruct gas flow or ventilation.
- Keep children away from the equipment during operation.
- If abnormalities occur, close the manual gas shut-off valve and contact an authorized service technician.
Installation
Upon receipt, verify the accessory kit includes the gas pressure regulator, conversion injectors, and lighter. Ensure adequate clearance from combustible and non-combustible surfaces as specified in the clearance table. The gas supply line must be at least 3/4" in diameter.


Gas Connection
A gas pressure regulator must be installed in the supply line. Failure to do so voids the warranty. Ensure the gas direction arrow on the regulator points toward the equipment. Check all connections for leaks using a sudsy soap solution; never use an open flame.
Gas Conversion
Units are factory-set for Natural Gas (NG). Conversion to LPG must be performed by a licensed and qualified technician. This involves replacing injectors and adjusting the pressure regulator fitting.
Operation
First-Time Use
Remove all protective PVC film. Clean the unit with mild soap and water. For griddles and charbroilers, run the burners for approximately 15 minutes to burn off manufacturing residue before first use.
Ignition Procedures
Specific ignition steps vary by model (Thermostatic Griddle, Manual Griddle, Charbroiler, Hot Plate). Generally, open the manual gas valve, light the pilot using the provided igniter, and turn the control knob to the desired setting.
Cleaning and Maintenance


- Daily: Clean the unit after it has cooled. Use a non-abrasive sponge and mild detergent.
- Grease Management: Empty the waste/grease tray at the end of each shift.
- Rust Prevention: If rust appears, scrub with an abrasive pad, wipe clean, and apply a thin layer of cooking oil.
- Maintenance: Only authorized technicians should perform internal maintenance or repairs.
