testing at test pressures less than to equal to 1/2 psig (3.45 KPA), hot plate must be isolated from gas supply piping. When pressure testing at test pressures above 1/2 psig (3,45 KPA), hot plate must be disconnected from gas supply piping system.

POSITIONING

The hot plate must be no closer than 6" from any combustible material and 16" away from any open flame. The hot plate must be placed under an exhaust hood with a fire retardant system. Your ventilation hood, when installed, must conform to the current ANSI/NFPA 96 standard. ALL connections and placement must comply with local and national codes. It is the responsibility of the owner and local installer to comply with these regulations when installing the hot plate.

RESTRAINING DEVICES

Hot plates must be restrained to prevent tipping when installed in order to avoid splashing, spilling, etc. of hot liquid. The restraining method may be a manner of installation or by separate means. Adequate means must also be provided to limit the movement of the appliance without depending on the connector,the quick-disconnect devise or its associated piping to limit the appliance movement.

Connectors must comply with the current ANSI Z21.69/CAN 1 6.10-88 standard for connectors for movable gas appliances. Quick-disconnect devices must comply with the current ANSI Z21.41/CAN 1 6.9- M79 standard for quick-disconnect devices meet these standards.

WARNING

￿PIPE JOINT COMPOUNDS RESISTANT TO PROPANE GASES MUST BE USED.

￿BEFORE OPERATING THIS HOT PLATE, CHECK PIPE JOINTS FOR LEAKS BY USING A SOAP AND WATER SOLUTION ONLY. DO NOT USE AN OPEN FLAME!

Main Gas Connection

FOR YOUR SAFETY: Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.

Connect the hot plate to the main gas supply line at the rear of the hot plate. The piping should be a minimum of 3/4" IPS supply pipe for a single hot plate.

A 3/4" NPT manual gas valve is shipped with each single hot plate for field installation. The required gas pressure for proper operation of each hot plate is 4" water column for natural gas and 10" water column for Propane gas.

In-line pressure regulators are not supplied by Keating. They are to be provided and installed by others as directed by local codes.

NOTE: If more than one gas hot plate 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 requirements for your particular model.

ELECTRICAL CONNECTION

The Keating hot plate with an optional spark ignitor is equipped with a 6' neoprene covered, 3 wire electrical cord with a three-pronged grounded plug for protection against electrical shock. This plug must be placed into a 120V properly grounded three-pronged outlet. For proper grounding procedures see local codes or, in the absence of local codes, the current National Electrical Code ANSI/NFPA 70 or Canadian Electrical Code CAN 22.1 as applicable.

NOTE: For hot plates with optional spark ignitors, the electrical wiring diagram is located on the front of the control panel. Hot plates with constant pilots do not require any electrical connections.

WARNING

DO NOT CUT OR REMOVE THE GROUNDING PRONG FROM THIS PLUG.

GAS LEAK TESTING

Prior to lighting your hot plate:

1.Make sure all manual gas valves and gas valves (infinite controls) are in the “OFF” (fully clockwise) position.

2.Turn main ON/OFF manual gas valve to the “ON” position.

3.Have your plumber or gas company check for leaks with a soap solution. (NEVER check with a match!)

4.Have your plumber or gas company representative light the constant pilot. (Not necessary if your hot plate has an optional spark ignitor.)
