GAS CONNECTIONS

GAS CONNECTIONS

CAUTION: Gas supply connections and any pipe joint compound used must be resistant to the action of propane gases.

Codes require that a gas shutoff valve be installed in the gas line ahead of the pasta cooker.

Connect gas supply to the pasta cooker. The gas inlet is located at the rear of the pasta cooker on the lower right when facing the rear of the machine.

The gas supply line must be at least the equivalent of 1/2" (13 mm) iron pipe. If using the optional quick- disconnect flex hose, 3/4" (19 mm) iron pipe must be used unless 3/4" to 1/2" (19 to 13 mm) reducing fittings are used. Make sure the pipes are clean and free of obstructions, dirt, and piping compound.

WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.

After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.

GAS PRESSURES AND ORIFICES

The standard orifices are set at 4" W.C. (Water Column) (1 kPa) manifold pressure for natural gas and 10" W.C. (Water Column) (2.5 kPa) manifold pressure for propane gas. A pressure regulator is supplied as part of the gas control valve.

TESTING THE GAS SUPPLY SYSTEM

When test pressures exceed 1/2 psig (3.45 kPa), the pasta cooker and its individual shutoff valve must be disconnected from the gas supply piping system.

When test pressures are 1/2 psig (3.45 kPa) or less, the pasta cooker must be isolated from the gas supply system by closing its individual manual shutoff valve.

LEVELING THE PASTA COOKER

Once gas connections have been made:

1.Place a spirit level on top of the pasta cooker.

2.Adjust the legs or casters to ensure that the pasta cooker is level front-to-back and side-to-side in the final installed position.

Adjust casters:

1.Loosen the set screws in the caster extension.

2.Adjust the height.

3.Tighten the set screws.
