2.0 INSTALLATION INSTRUCTIONS
UNPACKING

Immediately after unpacking, check for possible shipping damage. If the kettle is found to be
damaged, save the packaging material and contact the carrier within 15 days of delivery.

Before installing, verify that the electrical service agrees with the specifications on the rating plate
located on the lower rear of the kettle. If the supply and equipment requirements do not agree,
contact your dealer or Blodgett.

Select a location with drainage directly below the tangent draw-off. Allow sufficient rear clearance
from wall for kettle cover to lift upright freely and completely without obstructions.

INSTALLATION

1. The kettle must be installed in accordance with:
State and/or local codes.

In the USA, the National Electrical code, ANSI/NFPA-70 (latest edition). In Canada, the
Canadian Electrical Code, Part 1, CSA Standard C22.1 (latest edition).

2. Set the kettle in the installation location.

3. With the kettle in position, place a carpenter‟s level on top of the kettle and turn the adjustable
feet to level kettle side-to-side and front to back. On pedestal base models use shims to level
kettle.

4. Mark hole locations on floor through anchoring holes provided in flanged adjustable feet, or
holes provided on pedestal base.

5. Remove kettle and drill holes in locations marked on the floor (see installation diagram). Insert
proper anchoring devices to accommodate 5/16" size lag bolts (not supplied).

6. Reposition kettle. Re-level kettle by making necessary adjustments on flanged feet or shims.

7. 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

WARNING: Disconnect the electrical power supply and place a tag at the
disconnect switch to indicate that you are working on the circuit.

ELECTRICAL CONNECTIONS

A Control Box with power supply equivalent to electrical rating of the kettle should be located
conveniently nearby.

Remove the wiring compartment cover and make electrical connections per wiring diagram located
inside the control housing cover panel. A waterproof electrical connection from power supply to
rear of control housing must be provided.

Kettle must be grounded in accordance with requirements of the National Electrical Code or
applicable local codes.

Ground kettle to terminal provided in control housing.
Once proper connections are made, replace wiring compartment cover, turn power ON and check

for proper operation.
SERVICE CONNECTIONS
All internal wiring for the kettle is complete.
If faucet is provided connect water supply and check for proper operation.
INSTALLATION CODES AND STANDARDS
Your electric tilting kettle must be installed in accordance with:

1. State, provincial and local codes, or in the absence of local codes, with: C.S.A. C22.1
Canadian Electrical Code, Part 1, or in the U.S.A., the National Electrical Code ANSI/NFPA-70
(latest edition).

2. ANSI NFPA Standard #96, “Vapor Removal from Cooking Equipment,” (latest edition),
available from the National Fire Protection Association, Batterymarch Park, Quincy, MA,

02269.

3.0 DESCRIPTION

All electrically powered kettles described and referred to in this manual are pressure vessels of a
double-wall construction forming a sealed jacket (chamber) enveloping the lower two thirds of the
kettle bowl surface.

The kettle bowl is the container for the food product which ideally should be a liquid or semi-liquid
consistency to achieve complete contact with the bowl surface and thus fully absorb the heat
transmitted through that surface from the pressurized steam generated in the kettle jacket.

The jacket is intended to function as a self contained sealed chamber with a permanent solution of
water and antifreeze sufficient not only to immerse and thereby protect replaceable electric heating
elements, but also provide the steam source during the steam generating process.

The heating elements are thermostatically dial controlled to provide precise temperatures
throughout the range from slow simmer to rolling boil.

All stationary kettles are intended to be permanently floor mounted on legs with adjustable flanged
feet (KLS-E models) or pedestals (KLP-E models).

All kettles are equipped with a hinged counterbalanced stainless steel lid covering the kettle bowl
opening, a sanitary stainless steel tangent draw-off valve for the removal of the food product from
the kettle bowl, and a safety relief valve plumbed to the kettle jacket.

4.0 CAPACITIES

All models are suffixed with either - 20, - 30, - 40, - 60, - 80 or -100 to indicate the capacity of that
kettle in US gallons. Thus a KLS-40E indicates a two thirds jacketed electrically powered steam
kettle mounted on legs with a capacity of 40 US gallons.

5.0 FUNCTIONING MODE

All electrically powered self steam generating kettles consist of a jacket charged with a solution of
water and antifreeze sufficient to completely immerse and protect replaceable electric heating
elements.

To minimize tampering, the Safety Valve is plumbed toward the rear of the kettle jacket. Should
any component malfunction and cause the pressure in the jacket to reach the rated pressure of the
kettle, this protective device will open automatically and release excessive pressurized steam.

When the Power Switch is turned ON and the Temperature Control (Thermostat) Knob dialed
simultaneously, TEMPERATURE pilot light will come on and contactors will close to allow power to
elements. Steam generation will commence and continue until the water contained in the jacket
reaches the thermostatic temperature, manually preselected, at which point the Temperature
(thermostat) Control will de-energize and open the contactors cutting off power to heating elements
and TEMPERATURE pilot light will go off. When the temperature of the water in the jacket drops
slightly, the cycle will repeat itself thus making it possible to maintain any selected precise cooking
mode temperature.

The temperature required for the cooking process to function adequately must be greater than the
boiling point of the liquid food product. Further, the higher the temperature, the greater the steam
