Improper installation, adjustment, alteration, service or maintenance can cause property damage, injury or death. Read the installation, operating and maintenance instructions thoroughly before installing or servicing this equipment.

WARNING
Fire, Injury, Death Hazard This equipment must be installed by a qualified installer in accordance with all federal, state, and local codes. Failure to install this equipment properly can result in injury or death.

WARNING
Fire Hazard Do not install or use without 4″ legs. Use of this equipment without legs can cause the appliance to overheat and cause a fire.
CAUTION
Any loose dirt or metal particles that are allowed to enter the gas lines on this appliance will damage the valve and affect its operation. When installing this appliance, all pipe and fittings must be free from any internal contaminates. It is recommended that a sediment trap be installed in-line before the regulator.

Applicable Codes and Standards
United States
Vollrath recommends that all commercial cooking equipment be provided with a ventilation system in compliance with NFPA96:

• Cooking equipment that uses or produces grease (e.g. fryer, griddle), must be provided with hoods that are designed to capture grease and  provide fire protection.
• Equipment must be installed in accordance with the requirements and approval of the AHJ “Authority Having Jurisdiction.”
  NOTICE: Post instructions to be followed in the event the user smells gas. Consult your local gas supplier for these instructions and post them in a prominent location.
  NOTICE: The installation of this equipment must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, International Fuel Gas Code, ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installation Code, CSA B149.1, as applicable.

Install and Level the Legs
Ensure the equipment is level in all directions. Begin by tightening each leg securely. Then, as needed at each corner, rotate the adjustable foot.

Gas Piping

• Gas piping must be sized to ensure sufficient pressure and flow to meet the full-rated gas input of the equipment.
• Connection to an existing system requires that the existing system have capacity equal to or greater than the full-rated gas input of the  equipment.
• Joint compound (pipe dope) should be used sparingly and only on the male threads of the pipe joints. Such compounds must be resistant to the action of liquid propane (LP) gases.

Pressure Regulator
NOTICE: All commercial cooking equipment must have a pressure regulator on the incoming service line for safe and efficient operation.
NOTICE: Prior to connecting the regulator, check the incoming line pressure. The regulator can only withstand a maximum pressure of ¹/ PSI (14″ WC). If the line pressure is beyond this limit, a step-down regulator before the regulator provided will be required.
NOTICE: The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi (3.5 kPa).
NOTICE: The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to less than 1/2 psi (3.5 kPa).

• The arrow forged into the bottom of the regulator body shows the gas flow direction, and should point downstream to the equipment.
• The regulator provided with this equipment is configured for use with natural gas. Following the instructions in the LP Conversion Kit, it can be reconfigured for use with LP gas.
• The equipment comes fitted with a ¾” N.P.T. male adapter for connection to the pressure regulator.
• Check the pressure of the incoming gas line. The regulator can withstand a maximum pressure of 14″ WC (¹/ PSI). If the line pressure is beyond this limit, a step-down regulator will be required.

• Installer is responsible for correct orifice sizing.
• The orifice size is marked on the orifice/spud.
• Equipment is manufactured for 1035 BTU per cubic foot heat value of natural gas.

Gas Conversion

• Conversion from natural gas to liquid propane (LP) or vice versa must be performed by a qualified technician or service agent per the International Fuel Gas Code.
• Refer to the conversion kit instructions included with this equipment.

Manual Shut-Off Valve
A manual shut-off valve should be installed in an accessible location within 6 ft. (1.8m) of the equipment.

Test the Equipment
Check for Gas Leaks NOTICE: Matches, candle flame, or any other potential source of ignition shall not be used for this purpose.

1. Rotate the gas control knobs for the main burner(s) to the OFF position.
2. Remove the gas control knob(s).
3. Use a 5/16″ nut driver to remove the 4 screws securing the front panel. Remove the front panel to access the pilot burner control valve(s).
4. Locate the pilot burner control valves for each pilot light and turn them OFF by turning the small forward-facing screw clockwise until tight.
5. Connect the equipment to the gas supply.
6. Apply soapy water to each connection.
7. Turn ON the main supply valve.
8. Look for bubbles at the connections.
9. Tighten the connections as needed.

Light the Pilot Burners

1. Wait 5 minutes to allow any gas to dissipate.
2. To light the pilot burners, hold a flame source over the desired pilot burner while slowly turning its control valve screw counterclockwise, adjusting the flame to the desired intensity. Repeat for all pilot burners.

Test the Main Burners
After lighting all of the pilot burners, ensure that each main burner functions correctly.
After the lighting the pilots, the main burners can be ignited by pushing and turning the control knob from the “off” position to the desired setting. Visually check that the pilot light ignites the main burner.
The main burners can be extinguished by turning the control knob back to the “off” position. The pilot lights can be extinguished by shutting off the gas supply at the shut-off valve installed on the gas line.
