User Manual for Avantco 177AG Series Cooking Equipment

Quick guide from the manual

This manual provides essential instructions for the installation, operation, and maintenance of Avantco 177AG series commercial cooking equipment. Important: This equipment is for commercial use only and must be connected to the specific gas type identified on the rating plate. Always ensure the pressure regulator is installed to avoid voiding the warranty.

Installation Instructions

Installation must be performed by qualified, certified, and authorized personnel in accordance with local codes and the National Fuel Gas Code (ANSI Z223.1). Key installation steps include:

• Gas Connection: The supply line must be the same size or greater than the appliance inlet (3/4" NPT). Use sealant resistant to LP gas on all pipe joints.
• Pressure Regulator: A regulator is packed inside the appliance and must be installed on the incoming service line. Failure to install this regulator will void the warranty.
• Ventilation: Ensure the area around the appliance is clear. The unit should be placed under an exhaust hood constructed according to local codes.
• Leak Testing: All connections must be tested with a soapy water solution before lighting any pilots.

Operating Instructions

Before operating, ensure all gas connections are leak-free. Caution: Do not stand with your face close to the combustion chamber when lighting pilots.

Lighting and Shutdown

2. Turn the pilot valve(s) by adjusting the screw counter-clockwise, then light the standing pilot and adjust the flame to 1/4" high.
3. Turn ON the gas valve(s) to light the main burner.
4. For complete shutdown, turn OFF the gas valve(s) and turn the pilot valve(s) clockwise to shut off gas to the pilot(s).

Before First Use (Griddles)

• Clean the griddle surface with hot, soapy water to remove factory-applied protective oil.
• Rinse with a mixture of 1/4 cup vinegar to 1 qt. water.
• Spread unsalted solid shortening or liquid frying compound over the surface.
• Turn burners to medium until the shortening smokes, then turn off.
• Rub the melted shortening into the surface with burlap, allow to cool, and wipe with a thin film of oil.

Cleaning & Maintenance

Regular maintenance ensures equipment longevity and efficient operation.

Daily Maintenance

• Open Burners: Remove top grates, lift off burner heads and venturi, wash in hot soapy water, and reinstall.
• Griddles: Scrape with a nylon griddle scraper. Use a fine-grained stone only if necessary. Wash with hot soapy water, rinse with vinegar/water, then clear water. Re-oil the surface. Warning: Do not flood a hot griddle with cold water as it may warp or crack.
• Stainless Steel: Wipe regularly with hot soapy water. Do not use steel wool, abrasive cloths, or metal tools.
