GENERAL
Installation of the kettle must be accomplished by qualified installation personnel working to all applicable local and national codes. Improper installation of the product could cause injury or damage.
This equipment is built to comply with applicable standards for manufacturers. Included among those approval agencies are UL, A.G.A., NSF, ASME/N.Bd., CSA, CGA, ETL,  and others. Many local codes exist, and it is the responsibility of the owner/installer to comply with these codes.
Observe all clearance requirements to provide proper make-up airflow. Do not obstruct the flow of combustion and ventilation air. Check the rating plate to ensure that the kettle has been equipped to operate with the type of gas available at the installation.

VENTILATION
Gas-fired kettles are only to be installed under a ventilation hood in a room that has provisions for adequate makeup air. Further information can be obtained by referring to the  U.S.A. National Fire Protection Associations NFPA96 regulations. These standards have also been adopted by the National Building Code in Canada.

CLEARANCE REQUIREMENTS
This unit must be installed in accordance with the clearances shown on the rating label which is adhered to the unit.

FOR YOUR SAFETY. Keep the appliance area free and clear of combustible materials.

GAS
ENSURE THE GAS SUPPLY MATCHES THE KETTLE’S REQUIREMENTS AS STATED ON THE RATING PLATE. It is recommended that a sediment trap (drip leg) be installed in the gas supply line. If the gas pressure exceeds 14” water column, a pressure regulator must be installed, to provide a maximum of 14” water column gas pressure to the gas control valve. Connect the gas line to the manual valve located at the rear of the control box. Installation must be in accordance with local codes and/or the National Fuel Gas Code ANSI Z223.1 Latest Edition (USA) or the latest Installation Codes for Gas Burning Appliances and Equipment CAN/ CGA B149.1 and CAN/ CGA B149.2 (Canada). Use a gas pipe joint compound which is resistant to L.P. gas. Test all pipe joints for leaks with soap and water solution. Ensure that the gas pressure regulator is set for the manifold pressure indicated on the gas rating plate. The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of  1/2 psi (3.45 kPa). The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.45 kPa).

WATER
The sealed jacket of the gas-fired kettle is precharged with the correct amount of a water-based formula, and therefore, no water connection is required to the kettle jacket. The kettle can be equipped with optional hot and cold water taps, the taps require 1/2″ copper tubing as supply lines.

CLEANING
After installation, the kettle must be thoroughly cleaned and sanitized prior to cooking.

MOVING UNIT

1. While still on a skid, move the unit as close to the final installation position as possible.
2. Prepare the unit for lifting as shown in the diagram.
3. Lift gently with a forklift or jacks and remove the skid.
4. Lower gently to the ground and remove the forklift and blocking.
5. If the unit has to be re-positioned, slide gently. Do not twist or push one side of the unit excessively and cause binding on trunnions.

LEVELING

Note: Instructions reflect a more complicated twin mixer kettle – the process for a single mixer kettle is the same.

Recommended Leveling Procedure

1. With a straight edge, line the backs of the consoles up with each other (dotted line A).

2. Level and straight-edge backs of consoles (dotted line
   B). Adjustments are made by turning flanges on the back feet only.

3. Level consoles individually from front to back (dotted lines C ). Adjustments are made by turning flanges on the front feet only.

4. Re-check that the back is level (dotted line B ) and then the front (dotted line D ). Adjust if necessary.

5. Check that the mixer bridge is level and guide pins lock smoothly without binding. If not repeat steps 1 through 4. Guide Pins
   NOTE: See Operating Instructions before operating unit.

6. Make electrical connections (see electrical service connections) and test the mixer bridge as follows:
   ⇒ A / Raise mixer bridge.
   ⇒ B / Swing bridge out over center console.
   ⇒ C / Swing bridge to the left as far as possible.
   ⇒ D/ Lower bridge.
   ⇒ E / Bridge pins should enter the pinhole on the kettle perfectly, If not return to step 1 and repeat leveling steps.
   ⇒ F/ Raise bridge and swing to the far right (for twin mixers only).
   ⇒ G/ Repeat steps D and E (for twin mixers only).

7. Once positioned and leveled, permanently secure the kettle’s flanged feet to the floor using 5/16 inch stainless steel lag bolts and floor anchors (supplied by the installer).  Secure each of the flanged feet with one bolt in each hole. Seal joints of flanged feet with a silicone sealant.

ELECTRICAL SERVICE CONNECTIONS

ENSURE THE ELECTRICAL SUPPLY MATCHES THE KETTLE’S REQUIREMENTS AS STATED ON THE RATING LABEL.
Install in accordance with local codes and/or the National Electric Code ANSI/NFPA No 70-1981 (USA) or the Canadian Electric Code CSA Standard C22.1 (Canada). A separate fused disconnect switch must be supplied and installed. The kettle must be electrically grounded by the installer.
The electric supply must match the power requirements specified on the kettle’s rating plate. The copper wiring must be adequate to carry the required current at the rated voltage.

1. Ensure the main power is turned off before connecting wires.
2. Remove the screws at the rear of the mixer console cover, and remove the cover. A wiring diagram is affixed to the underside of the console cover.
3. Feed permanent copper wiring 18″ through the cutout in the bottom of the console. Connect wiring in the junction box at the bottom of the console.
4. Turn the main power back on.
5. Check for correct rotation of the electric motor (access by removing the top front cover on the center console). If rotation is incorrect, disconnect the main power and reverse any two of the three live lines.
6. Replace the console cover and secure it with screws.

COMPRESSED AIR CONNECTION

Mixer Kettles with an air-activated discharge valve require a minimum of 90 PSI to operate correctly.
If the unit is also supplying air to a Metering Filling Station then a pressure of 100 PSI at a minimum volume of 25 CFM is required.
The air supplied to the mixer should be clean and dry. No oil should be added to the supply air. We recommend the compressed air system be equipped with a drier, filter, and automatic water dump on the air compressor receiver tank. If the distance between the tank and the unit is less than 100 feet then a minimum line size of 3/4″ is required. A  distance of 100 to 300 feet requires a minimum 1″ line.

STAINLESS STEEL EQUIPMENT CARE AND CLEANING
(Supplied courtesy of Naeem. For more information visit their website at www.nafem.org)

Contrary to popular belief, stainless steels ARE susceptible to rusting. Corrosion on metals is everywhere. It is recognized quickly on iron and steel as unsightly yellow/orange rust. Such metals are called “active” because they actively corrode in a natural environment when their atoms combine with oxygen to form rust.
Stainless steels are passive metals because they contain other metals, like chromium, nickel, and manganese that stabilize the atoms. 400 series stainless steels are called ferritic,  contain chromium, and are magnetic; 300 series stainless sheets of steel are called austenitic, contain chromium and nickel; and 200 series stainless, also austenitic, contains manganese, nitrogen, and carbon. Austenitic types of stainless are not magnetic, and generally provide greater resistance to corrosion than ferritic types.
With 12-30 percent chromium, an invisible passive film covers the steel’s surface acting as a shield against corrosion. As long as the film is intact and not broken or contaminated, the metal is passive and stainless. If the passive film of stainless steel has been broken, the equipment starts to corrode. At its end, it rusts.

Enemies of Stainless Steel
There are three basic things that can break down the stainless steel passivity layer and allow corrosion to occur.

1. Mechanical abrasion
2. Deposits and water
3. Chlorides

Mechanical abrasion means those things that will scratch a steel surface. Steel pads, wire brushes, and scrapers are prime examples.

Water comes out of the faucet in varying degrees of hardness. Depending on what part of the country you live in, you may have hard or soft water. Hard water may leave spots,  and when heated leave deposits behind that if left to sit, will break down the passive layer and rust stainless steel. Other deposits from food preparation and service must be properly removed.

Chlorides are found nearly everywhere. They are in the water, food, and table salt. One of the worst chloride perpetrators can come from household and industrial cleaners.

So what does all this mean? Don’t Despair!
Here are a few steps that can help prevent stainless steel rust.

1. Use the proper tools.
   When cleaning stainless steel products, use non-abrasive tools. Soft cloths and plastic scouring pads will not harm steel’s passive layer. Stainless steel pads also can be used but the scrubbing motion must be in the direction of the manufacturers’ polishing marks.

2. Clean with the polish lines.
   Some stainless steel comes with visible polishing lines or “grain.” When visible lines are present, always scrub in a motion parallel to the lines. When the grain cannot be seen, play it safe and use a soft cloth or plastic scouring pad.

3. Use alkaline, alkaline chlorinated, or non-chloride-containing cleaners. While many traditional cleaners are loaded with chlorides, the industry is providing an ever-increasing choice of non-chloride cleaners. If you are not sure of chloride content in the cleaner used, contact your cleaner supplier. If your present cleaner contains chlorides, ask your supplier if they have an alternative. Avoid cleaners containing quaternary salts; they also can attack stainless steel and cause pitting and rusting.

4. Treat your water.
   Though this is not always practical, softening hard water can do much to reduce deposits. There are certain filters that can be installed to remove distasteful and corrosive elements. To ensure proper water treatment, call a treatment specialist.

5. Keep your food equipment clean.
   Use alkaline, alkaline chlorinated, or non-chloride cleaners at recommended strength. Clean frequently to avoid build-up of hard, stubborn stains. If you boil water in stainless steel equipment, remember the single most likely cause of damage is chlorides in the water. Heating cleaners that contain chlorides have a similar effect.

6. Rinse, rinse, rinse.
   If chlorinated cleaners are used, rinse and wipe equipment and supplies dry immediately. The sooner you wipe off standing water, especially when it contains cleaning agents, the better. After wiping equipment down, allow it to air dry; oxygen helps maintain the stainless steel’s passivity film.

7. Never use hydrochloric acid (muriatic acid) on stainless steel.

8. Regularly restore/passivate stainless steel.

Recommended cleaners for specific situations

sponge
Fingerprints & smears| Arcal 20, Lac-O-Nu Ecoshine| Provides barrier film
Stubborn stains & discoloration| Cameo, Talc, Zud, First Impression| Rub in direction of polish lines
Grease & fatty acids, blood, burnt-on-foods| Easy-off, De-Grease It Oven Aid| Excellent removal on all finishes
Grease & oil| Any good commercial detergent| Apply with a sponge or cloth
Restoration/Passivation| Benefit, Super Sheen|

Review

1. Stainless steels rust when passivity (film-shield) breaks down as a result of scrapes, scratches, deposits, and chlorides.
2. Stainless steel rust starts with pits and cracks.
3. Use the proper tools. Do not use steel pads, wire brushes, or scrapers to clean stainless steel.
4. Use non-chlorinated cleaners at recommended concentrations. Use only chloride-free cleaners.
5. Soften your water. Use filters and softeners whenever possible.
6. Wipe off a cleaning agent(s) and standing water as soon as possible. Prolonged contact causes eventual problems.

To learn more about chloride-stress corrosion and how to prevent it, contact the equipment manufacturer or cleaning materials, supplier. Developed by Packer Engineering, Naperville, Ill., an independent testing laboratory.

Kettle Safety Inspection Checklist

Just recently a competitor’s steam jacketed kettle exploded causing serious personal injury and damage to a kitchen. In most cases, these accidents are caused by poor maintenance and/or incorrect installation.
We at Cleveland would like to restate that regular inspection and maintenance of units is essential to obtain trouble-free and safe operation of equipment. Inspections must include testing of the pressure relief valve and checks of the operating system to ensure that it has not been altered.
No safety features designed into the equipment should ever be tampered with. Tampering with or bypassing controls is a very dangerous practice and unfortunately, we have seen several cases of this. Following is a short list of the most common and the most dangerous alterations performed on kettles.

SAFETY VALVE:

Incorrect Installations

1. The safety valve has a plug threaded into the discharge opening preventing any steam from escaping.
2. The safety valve’s tube diameter has been reduced.
3. The safety valve is sticking, frozen shut, or plugged. To test, refer to Service Bulletin SE90038 rev. 2, “Pressure Relief Valve Periodic Testing”.
4. The safety valve is plumbed to a drain or water line creating back pressure and reducing flow.

|
---|---

SAFETY THERMOSTAT:

Incorrect Installations

1. The safety thermostat probe is not completely inserted into the tubing.
2. The safety thermostat probe is removed from the tubing.
3. The safety thermostat electrical connection is bypassed.

Low Water Level Probe:

Operating Thermostat:

260º – 270º MAXIMUM KETTLE TEMPERATURE
If the maximum temperature is not in this range (on an empty kettle), refer to the “Calibrating Procedure” in the unit’s Installation, Operation & Service Manual.
