Frequently Asked Questions - KLS-25E Blodgett

What does the low water light indicate on my Blodgett KLS-25E kettle?

The low water light indicates that the water level in the steam jacket is too low. This activates the low water cut-off device, which turns off the heating elements to prevent damage. Check the vacuum/pressure gauge and follow the air venting instructions in the manual to restore proper water level.

How do I properly install the KLS-25E kettle?

Install the kettle on a level floor with proper drainage below the draw-off valve. Leave at least 3" clearance on sides and back. Bolt the flanged feet to the floor using expansion shields and 5/16" lag bolts. Seal around the base with silicone to meet NSF requirements. Connect to a waterproof electrical supply matching the data plate specifications.

What is the correct way to operate the kettle?

Ensure the draw-off valve is closed and the vacuum gauge reads 20-25 in Hg for a cold kettle. Turn the power switch on, preheat by setting thermostat to 8 until the pilot light goes off. Add food product (for milk/egg based items, start cold). Adjust thermostat to desired setting: 6-7 for simmer, 8-10 for boil. Turn off when cooking is complete. Remove food by ladling or using the draw-off valve.

How do I clean the kettle after use?

Turn off power and let cool. Rinse interior with warm water and drain. Use a nylon brush with mild detergent to clean the bowl and draw-off valve. Do not use steel wool or scouring powders. For hard residue, soak with warm water at low temperature. Disassemble the draw-off valve by turning the hex nut counterclockwise, clean the stem and disc carefully, then reassemble. Flush with clean water and leave valve open when not in use.

Why does my kettle not heat up?

Possible causes: power switch off, thermostat set too low, low water level (low water light on), or a tripped circuit breaker. For KLT models, also check that the kettle is in the vertical position (tilt interlock). If the vacuum gauge shows low vacuum, air may be in the system; follow the air venting procedure in the manual.

How do I vent air from the steam jacket?

When the kettle is cold and the vacuum gauge reads below 20 in Hg, turn on the kettle and allow temperature to rise above 0 PSI. Open the bleed vent one full turn for 10 seconds, then close. Repeat if necessary. This removes air from the system and ensures proper steam generation.

Can I use the kettle to cook acidic foods?

Yes, but avoid prolonged exposure to highly acidic foods and always clean immediately after use. Corrosive cleaning agents containing chlorides, acids, or salts can damage the stainless steel and void the warranty. Use only mild detergents.

What is the recommended maintenance schedule?

Daily: clean the kettle after each use. Monthly: check the safety relief valve for proper operation, inspect electrical connections. Annually: have an authorized service agency perform a thorough inspection of the steam jacket and electrical components.

How do I replace the draw-off valve disc?

Turn the hex nut counterclockwise to remove the valve stem and disc. Inspect the vulcanized rubber disc for damage. Replace if necessary. Reassemble by hand, ensuring the disc seats properly. Do not overtighten as this can damage the rubber.

Where is the serial number located?

The serial number data plate is located on the rear of the kettle. Have this number available when contacting Blodgett for service or support.

DESCRIPTION

Floor model kettles are self-contained, self-generating steam jacketed vessels for cooking large volumes of liquid and semi-liquid food products. All models include a hemispheric shape based on double-wall construction forming a steam jacket reservoir around the lower two-thirds of the kettle. The reservoir is charged with distilled water, rust inhibitor and antifreeze solution and is vacuum-sealed. Kettles are equipped with electric heating elements and controls including a low water cut-off device for protection of heating elements.

Two model series differ in that KLT-__E units are leg-mounted tilting kettles while KPS-__E units are pedestal mounted stationery kettles. Optional leg mounting of the pedestal models is designated by the model number series KLS-__E. The missing figures of the model numbers are the two digits representing the kettle capacity, ie, KLT-20E for a 20 gallon tilting kettle.

BASIC FUNCTIONING

Self-contained kettles operate by generating steam in the kettle reservoir; the sequence of functioning, which occurs during operation, is as follows:

1. Operator places the power switch in the ON position and sets the thermostat knob at the required setting from "1" to "10" - 140° to 290°F (60° to 144°C) - jacket temperature.

2. Control circuit is normally completed to the thermostat control if two standard conditions exist:

a. Water level in kettle jacket is adequate to prevent circuit interruption by the low water cut-off device. An activated cut-off is evidenced by the Low Water light turning on and heating element cut off.
b. Kettle is in vertical position with circuit completed through the tilt interlock switch (KLT-E series only).

1. Thermostatic control contacts close to energize heater contactor coils and turn temperature Indicator light on.

2. Power is applied to heaters through closed contactor power contacts.

3. As temperature of water rises in kettle reservoir, the steam pressure increase is indicated by the vacuum pressure gauge.

NOTE: Gauge normally reads 22-30 IN. Hg (74-100 k/Pa) (below 0 PSI, prior to heaters turning on. Air is eliminated from the system when jacket is filled (with the kettle reservoir at a pressure above 0 PSI) by opening the bleed vent one full turn for 10 seconds and closing.

1. When temperature of steam in the reservoir reaches the temperature coinciding with the thermostat setting, the thermostat switch opens to break the circuit to the contractor coils and shuts off the elements. Any number of on and off cycles of the control thermostat, contactors and elements will occur as required to maintain thermostat setting,

SERVICE

Required service, both preventive and corrective. is explained in the maintenance section. Should repairs be required, a network of authorized agencies is available to assist with prompt service. A current Directory of Authorized Service Agencies may be found by visiting our website, www.blodgett.com.

The model and serial numbers must be referenced when corresponding with Blodgett. The data plate containing the serial number pertaining to the equipment is located on rear of kettle.

1. Select a location to provide drainage directly below the tangent draw-off. Allow sufficient rear clearance from wall for kettle cover to lift upright freely and completely without obstructions.
2. Mark hole locations through flanged adjustable feet on KLT-E models. Remove kettle.
3. Drill holes on marked hole locations, and insert expansion shields to accommodate 5/16" size lag bolts.
4. Reposition kettle. On KLS-__E models level by making necessary adjustments on flanged feet.
5. Bolt down kettle and seal with Silastic or other equivalent sealing compound. Sealant must be applied not only to bolt heads but also around flanges or pedestal base making contact with floor surface to fulfill NSF requirements. Wipe off excess sealant immediately.
6. A control box with power supply equivalent to electrical
7. Rating of kettle should be located conveniently nearby.
8. A waterproof electrical connection for power supply to rear of control housing must be provided.
9. Ground kettle to terminal provided inside control housing.
10. Turn power ON and check for proper operation.

OPERATION

1. Check kettle pressure gauge that reading indicates 20-25 vacuum for a cold kettle. If vacuum is insufficient, air venting instructions must be followed. If equipped with draw off valve ensure valve is closed.
2. Place kettle power switch in ON position.
3. Preheat kettle by turning thermostat knob to '8' and wait until temperature pilot light goes off.

NOTE: Food products with milk or egg base should be placed into cold kettle and then the cooking operation begun. Avoid sudden contact of these food products to hot kettle bowl surface since caking/adhering will occur.

1. Place food product into kettle bowl. Close kettle cover.
2. Adjust thermostat knob to temperature cooking mode. Setting of 6-7 will provide simmer and 8-10 low to rolling boil.
3. Turn both kettle power switch and thermostat knob OFF when cooking has been completed.
4. Remove food product by ladling out of kettle bowl or by opening draw-off valve and pouring into a suitable container.

WARNING

DRAW OFF VALVE HAS A VUCANIZED RUBBER COATED STEAM FOR BETTER SEALING. DO NOT OVERTIGHTEN. THIS MAY CAUSE THE RUBBER TO PULL AWAY FROM STEAM AND PERMANENTLY DAMAGE IT.

CLEANING
