GAS CONNECTIONS AND PIPE SIZE

The Miraclean® Griddle requires a standard gas pipe size of 3/4 inch (19mm) I.D. connection. The size of the gas supply pipe is very important if the pipe is too small you will have low gas pressure at the Miraclean® Griddle manifold. Low gas pressure will cause slow recovery and/or delayed ignition. If you have a question about gas pipe size call your local gas company.

Before connecting new pipe to the Miraclean® Griddle the pipe must be blown out to remove all foreign

FLEXIBLE GAS CONNECTORS AND QUICK

DISCONNECT DEVICES

For an appliance equipped with casters:

The installation shall be made with a connector that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 or the Standard for Connectors for Moveable Gas Appliances, CAN/CGA- 1.16, and a quick disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANSI Z21.41 or the Standard for Quick Disconnect devices for Use with Gas Fuel, CAN1-6.9.

particles. These particles in the controls or burners may cause improper or dangerous operating conditions.

Pipe joint compounds that are used on threaded joints of appliance piping shall be resistant to the action of liquified petroleum gases. When using pipe joint compound do not apply to the first two threads. Use only very small amount and only on male threads. This will prevent clogging of burner orifices and the gas

Adequate means must be provided to limit the movement of the appliance without depending on the connector and the quick-disconnect device or its associated piping to limit the appliance movement.

valve. Never use compound on female threads as it might be pushed into the gas valve.

Have your installer check for gas leaks using a soap and water solution before operating. DO NOT USE AN OPEN FLAME TO CHECK FOR GAS LEAKS.

1)The Miraclean® Griddle and its individual shut off valves 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 (3.45kPa) (13.84 in WC) High pressure can damage the gas

valve causing a hazardous condition. WARNING 2.) The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of

The restraint means must be attached to the rear of the Miraclean® Griddle within 2" of the center line and approximately 1-5/8" from the bottom of the cabinet back to allow the restraining bolt to be anchored to the cabinet back between the cabinet bottom and inner liner to ensure positive support to restrain Miraclean® Griddle movement and not depend on the flexible gas connector, quick-disconnect or piping to limit the Miraclean® Griddle movement.

If disconnection of the restraint is necessary, it must be reconnected when the Miraclean® Griddle is returned to its originally installed position.

to check for leaks. The required gas pressure for proper operation of each Miraclean® Griddle is 4" water column for natural gas and 10" water

column for propane gas at the manifold.

If more than one gas unit is on the same supply line, you may require a larger line. Consult your local gas company to assure adequate volume and pressure. Refer to serial plate for proper gas requirement for your particular model.

The Miraclean® Griddle will operate at its highest efficiency when properly leveled. Place a level on the Miraclean® Griddle plate from side to side. For griddles on legs, the bottom foot of the leg is adjustable. Turn counterclockwise to decrease height, or clockwise to increase height until level. For griddles on stands with casters, the casters are adjustable by loosening the jam nut. When the desired level is reached, tighten the jam nut. Adjustments of more than 3/4" are not recommended on any caster. The same procedure should be followed to level the Miraclean® Griddle from front to back.
