6.2Accessing the Rethermalizer for Servicing

DANGER

Moving a rethermalizer filled with hot water may cause spilling or splattering of the hot water. Always drain the cookpot before attempting to relocate the unit for servic- ing.

1.Shut off the gas supply to the unit. Unplug the electrical power cord. Disconnect the unit from the gas supply.

2.Remove any attached restraining devices.

3.Relocate the rethermalizer for service accessibility.

4.After servicing is complete, reconnect the unit to the gas supply, reattach restraining devices, and plug in the electrical power cord.

6.3Cleaning the Gas Valve Vent Tube

Refer to Semi-Annual Checks and Services in Chapter 4, Preventive Maintenance.

6.4Checking the Burner Manifold Gas Pressure

Refer to Semi-Annual Checks and Services in Chapter 4, Preventive Maintenance.

6.5Measuring Flame Current

When the burner flame is properly adjusted, it will produce a current between 3.5 μA and 6.5 μA. Flame current is measured by placing a microamp (not milliamp) meter in series with the white sens- ing wire on the ignitor. This is accomplished as follows:

1. Turn the unit OFF (press the button).

2. Disconnect the white flame sensor wire

from one of the burner ignitor assemblies

 

 

and connect it to the positive lead of the

 

 

meter. Connect the negative lead of the

 

 

meter to the terminal from which the

 

 

sensing wire was removed.

 

 

3.Turn the unit ON (press the button). When a cold unit is first turned on, the burner will cycle on and off repeatedly until the temperature in the cookpot reaches 180°F (82°C). When the water in

the unit exceeds that temperature, the burner will stay on until the setpoint is reached. Check the reading when the burner has been on continuously for at least one minute.
