only on the type of gas specified by the user and indi- cated on the serial plate located inside the door. The gas may be natural, propane or manufactured. The type of gas cannot be converted to another gas fuel by turning or engaging a switch.
GAS CONNECTIONS AND PIPE SIZE
A single Keating Gas Fryer requires a standard gas pipe size of 3/4 inch (19mm) I.D. connection. Multiple fryers with a common manifold will require a minimum of 1 1/4 inch I.D. gas supply line. The size of the gas supply pipe is very important. If the pipe is too small you will have low gas pressure at the Keating Gas Fryer 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.
CAUTION
Before connecting new pipe to the Keating Gas Fryer the pipe must be blown out to remove all foreign parti- cles. These particles in the controls or burners may cause improper or dangerous operating conditions.
CAUTION
Pipe joint compounds that are used on threaded joints of appliance piping shall be resistant to the action of liq- uefied petroleum gases (Loctite PST 56765). 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 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 Keating Gas Fryer and its individual shut off valves must be disconnected from the gas supply pip- ing 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 caus- ing a hazardous condition.
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 gas supply pip- ing system at test pressures equal to or less than 1/2 psi (3.45 kPa).
NOTE: Line pressure must be kept below 10” (Nat), 13” (LP) to avoid damage to the gas valve.
The required gas pressure for proper operation of each fryer is 4" water col- umn for natural gas and 10" water col- umn for propane gas at the burner 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.
FLEXIBLE GAS CONNECTORS AND QUICK DIS-
CONNECT 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 Con- nectors for Moveable Gas Appliances,
RESTRAINING DEVICES
1.) Adequate means must be provided to limit the movement of the appliance without depending on the connector and the
Fryer must also be restrained to pre- vent tipping when installed so that hot liquid splashing is avoided.
2.) The restraint means must be attached to the rear of the Keating Gas Fryer within 2" of the center line width and approximately
IF DISCONNECTION OF THE RESTRAINT IS NEC- ESSARY, IT MUST BE RECONNECTED WHEN THE KEATING GAS FRYER IS RETURNED TO ITS ORIG- INALLY INSTALLED POSITION.
INSTALLATION
The installer is responsible for attaching the tipping restraint.
ELECTRICAL CONNECTION
The Keating Gas Fryer, when installed, must be elec- trically grounded in accordance with local codes, or in the absence of local codes, the National Electrical Code, ANSI/NFPA No. 70. or the Canadian Electrical Code,
electrical supply must be 120 VAC, 60 Hz.
