Safety Practices for Servicer

Safe and satisfactory operation of gas cooktops depend upon its design and proper installation. However, there is one more area of safety to be considered:

Servicing

Listed below are some general precautions and safety practices which should be followed in order to protect the service technician and consumer during service and after service has been completed.

1. Gas smell—Extinguish any and all open flames and open windows.

2. Turn gas off—Service cooktop with gas turned off unless testing requires it.

3. Checking for gas leaks—Never check for leaks with any kind of open flame. Soap and water solution should be used for this purpose. Apply solution to suspected area and watch for air bubbles which indicates a leak. Correct leaks by tightening fittings, screws, connections, applying approved compound, or installing new parts.

4. Using lights—Use a hand flashlight when servicing cooktops or checking for gas leaks. Electric switches should not be operated where leaks are suspected. This will avoid creating arcing or sparks which could ignite the gas. If electric lights are already turned on, they should not be turned off.

5. Do not smoke—Never smoke while servicing gas cooktops, especially when working on piping that contains or has contained gas.

6. Check cooktop when service is completed—After servicing, make visual checks on electrical connection, and check for gas leaks. Inform consumer of the condition of cooktop before leaving.

7. Adhere to all local regulations and codes when

performing service.

Before Installing

Installing the gas cooktop in compliance with local electrical and gas building codes results in proper operation and consumer satisfaction with the cooktop.
