INSTALLATION

NOTICE

Installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1, Natural Gas Code, CAN/CGA-B149.1, or the Propane Installation Code, CAN/CGA-B149.2, as applicable.

NOTICE

These installation procedures must be followed by qualified personnel or warranty will be void. Local codes regarding installation vary greatly from one area to another. The National Fire Protection Association, Inc. states in its NFPA 96 latest edition that local codes are the “authority having jurisdiction” when it comes to installation requirements for equipment.

Step 1: Unpack

IMMEDIATELY INSPECT FOR SHIPPING DAMAGE
All containers should be examined for damage before and during unloading. The freight carrier has assumed responsibility for safe transit and delivery. If damaged equipment is received, either apparent or concealed, a claim must be made with the delivering carrier.
Apparent damage or loss must be noted on the freight bill at the time of delivery. The freight bill must then be signed by the carrier representative (Driver). If the bill is not signed, the carrier may refuse the claim. The carrier can supply the necessary forms.
A request for inspection must be made to the carrier within 15 days if there is concealed damage or loss that is not apparent until after the equipment is uncrated. The carrier should arrange an inspection. Be certain to hold all contents and all packing materials.

Uncrate carefully. Report any hidden damage to the freight carrier IMMEDIATELY.
Do not remove any tags or labels until the unit is installed and working properly.

All Propane (LP) Gas Fryers MUST HAVE AN APPLIANCE REGULATOR INSTALLED in addition to the tank or stage regulator. IF A PROPANE FRYER IS INSTALLED WITHOUT THE CORRECT PRESSURE REGULATOR, PARTS WILL BE DAMAGED AND THE WARRANTY WILL BE VOID.

The appliance regulator must be set to gas pressure between 11” W.C. and 12” W.C.
Note: There is a pressure regulator “built in” to the combination gas valve, if the incoming pressure is at 10” W.C.
or lower this “built in” regulator will act as a restriction and cause incomplete combustion and sooting. If the gas pressure is above 12” W.C. damage could occur to the “built in” pressure regulator and in that case it would have to be replaced , this would not be covered by the warranty.

Step 2: Install the Legs (or optional casters) and Restraints.

A set of legs or casters is packed with the fryer. Mounting fasteners are pre- mounted on the baseplates.

Raise fryer sufficiently to allow legs or casters to be screwed into the baseplate. For safety, “shore up” and support the fryer with an adequate blocking arrangement strong enough to support the load.
Screw the four legs or casters to the plate on the bottom of the fryer. When casters have been ordered, the casters having a locking-brake should be attached under the front of the fryer.
Lower the fryer gently. Never drop or allow the fryer to fall.
Use a level to make sure that the fryer is level. Each caster, or the tubular-end of each leg, can be screwed in or out to lower or raise each corner of the fryer.
Attach restraints as required by local codes.

NOTICE

Unit must be level to ensure maximum performance. Improper leveling may void warranty.

WARNING

When this appliance is installed with casters, it must be installed with the casters supplied, a connector complying with either ANSI Z21.69 or CAN/CGA-6.16 and a quick disconnect device complying with either ANSI Z21.41 or CAN1-6.9. It must also be installed with restraining means to guard against transmission of strain to the connector, as specified in the appliance manufacturer’s instructions.

WARNING

All fryers must be restrained to prevent tipping in order to avoid the splashing of hot liquid. The means of restraint may be the manner of installation.

Step 3: Flue Installation

Unpack the flue box and flue wrap
Slide the flue box over the flue and secure it with the two self-tapping screws using a 5/16″
Slide the flue wrap over the flue.
Secure it with four self-tapping screws two on the back and one on each side using a 5/16″ socket.

Step 4: Check Clearances and Ventilation

Select a firm, level location for your fryer. Leave clearance, whenever possible, so that access from the rear is possible to permit cleaning. If the unit is to be set on non-combustible flooring, such as a concrete slab, 3 inches minimum toe room must be provided to prevent restriction of the air opening in the bottom of the unit

WARNING

There must be adequate clearance between fryer(s) and construction. Clearance must also be provided in front for servicing and for operation.

Minimum Clearances From Combustible Construction:

Sides: Six (6) Inches
Rear: Six (6) Inches

ALL AVANTCO EQUIPMENT FLOOR FRYERS SHALL BE INSTALLED WITH AT LEAST A 16 INCH SPACE BETWEEN THE FRYER AND SURFACE FLAMES FROM ADJACENT EQUIPMENT.

SUITABLE FOR INSTALLATION ON COMBUSTIBLE FLOORS. No additional side and rear clearance is required for service as the fryer is serviceable from the front

WARNING

Improper ventilation can result in personal injury or death. Ventilation that fails to properly remove flue products can cause headaches, drowsiness, nausea, or could result in death. Unit Must be installed under a ventilation Hood.

All units must be installed in such a manner that the flow of combustion and ventilation air is not obstructed.

Provisions for adequate air supply must also be provided. Do NOT obstruct the bottom front of the unit, as combustion air enters through this area. Be sure to inspect and clean the ventilation system according to the ventilation equipment manufacturer’s instructions.

Due to the variety of problems that can be caused by outside weather conditions, venting by canopies or wall fans is preferred over any type of direct venting. It is recommended that a canopy extend 6″ past the appliance and the bottom edge be located 6’6″ from the floor. Filters should be installed at an angle of 45° or more from the horizontal. This position prevents dripping of grease and facilitates collecting the run-off grease in a drip pan, usually installed with a filter. A strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance or may extinguish pilot flames. Fresh air openings approximately equal to the fan area will relieve such a vacuum. In case of unsatisfactory performance on any appliance, check the appliance with the exhaust fan in the “OFF” position. Do this only long enough to check equipment performance, then turn hood back on and let it run to remove any exhaust that may have accumulated during the test.

The exhaust fan should be installed at least 2 feet above the vent opening at the top of the fryer.
Make sure all ventilation meets local code requirements.
This unit is not intended to be connected directly to an outside flue

Step 5: Gas Connection

A 3/4″ male NPT line for the gas connection is located near the lower right rear corner of the fryer. The serial plate (located inside the front door of the fryer) indicates the type of gas the unit is equipped to burn (natural gas or propane). The fryer should be connected ONLY to the type of gas for which it is equipped.
A circuit diagram is located inside the front door of the fryer.
All Avantco Equipment equipment is adjusted at the factory; however, pilot height should be checked at installation and adjusted, if necessary.
For orifice sizes and pressure regulator settings, see the chart on page 5. If the fryer is being installed at over 2,000 feet altitude and that information was not specified when ordered, contact the appropriate authorized Avantco Equipment Service Representative or the Avantco Equipment Service Department. Failure to install with proper orifice sizing will result in poor performance and may void the warranty.
If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in accordance with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code, CAN/CGA-B149.2, as applicable.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas necessary for satisfactory performance. A combination gas valve and pressure regulator, which is provided with each unit, is set to maintain a 4″ W.C. manifold pressure for natural gas or 10.0″ W.C. manifold pressure for propane gas. However, to maintain these conditions the pressure on the supply line, when all units are operating simultaneously, should not drop below 7″ W.C. for natural gas or 11″ W.C. for propane gas. Fluctuations of more than 25% on natural gas or 10% on propane gas will create problems and affect burner operating characteristics. A 1/8″ tap to measure the manifold pressure is located on the combination gas valve, which is on the burner manifold located directly below the burners inside the cabinet.
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.
It is recommended that an individual manual shutoff valve be installed in the gas supply line to the unit.
Use pipe joint compound that is suitable for use with both natural and LP gas on all threaded connections.

CAUTION

OR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO CHECK FOR GAS LEAKS. ALL CONNECTIONS MUST BE CHECKED FOR LEAKS AFTER THE UNIT HAS BEEN PUT INTO OPERATION. TEST PRESSURE SHOULD NOT EXCEED 14″ W.C

CAUTION

THIS APPLIANCE AND ITS INDIVIDUAL COMBINATION GAS VALVE MUST BE DISCONNECTED FROM THE GAS SUPPLY PIPING SYSTEM DURING ANY PRESSURE TESTING OF THAT SYSTEM AT TEST PRESSURES IN EXCESS OF 14”WC (1/2 PSIG or 3.45 kPa).

If the incoming gas pressure is in excess of 14″WC (1/2PSI, 3.45 kPa), a proper step-down regulator will be required. See PHOTO 1 for LP application

Connect the gas supply directly to the 3/4″ male NPT connector located near the lower left rear corner of the fryer. When tightening the supply pipe, be sure to hold the mating connector extending from the unit securely with a wrench. This will prevent any damage or distortion to the internal piping and controls of the unit

WARNING

Checking For Gas Leaks: Using a gas leak detector or a soapy water solution is recommended for locating gas leaks. Matches, candle flame, or other sources of ignition shall not be used for this purpose.

Check entire piping system including the internal piping and Pipe Union inside of the fryer for leaks.

DO NOT use an open flame to check for leaks. Check all gas piping for leaks with a soap and water solution before operating the unit.

After connecting the gas supply, check again that the fryer is level. Use a long spirit level four ways; across the front and rear of the fry pot, and along each edge.

NOTICE
Do not restrict the flow of gas. Use only commercially approved gas appliance connectors OR Flexible Hoses! Non-commercial connectors or Flexible hoses will void your warranty.

OPERATION

LIGHTING

CAUTION

IF YOU SMELL GAS DURING THE LIGHTING PROCEDURE, IMMEDIATELY SHUT OFF THE GAS SUPPLY UNTIL THE LEAK HAS BEEN CORRECTED

Open the front burner compartment door
Turn the thermostat to the “OFF” position by aligning “OFF” on knob with the hole in the panel (Fig. 1)
Turn the knob of the combination gas valve (Fig. 2) from “OFF” to “PILOT”, ensure “PILOT” aligns with “dot” shown in Fig. 3
Press down on the knob and hold to release gas for pilot light, do not hold for more than 30 seconds at a time
While holding the knob down, use a match or lighter to ignite the pilot light. Once pilot light is lite, continue to hold the knob down for about 30 seconds
After holding and releasing knob, pilot light should stay on. If light goes out, repeat previous steps as necessary. If you smell gas, stop lighting procedure and turn knob off and check for leaks
If the pilot light stays on after releasing the knob, turn the knob to the “ON” position, shown in Fig. 4
DO NOT turn the thermostat “ON” until the fryer pot is filled with oil or solid shortening
Once fryer pot is filled, turn the thermostat to the desired temperature

FILLING THE FRY POT

Close drain valve completely before filling the fry pot.
When the fryer is new, fill the fry pot with water and clean thoroughly (see “Weekly Cleaning” on page 13) in order to remove protective coatings and any foreign matter.
The recommended solid shortening capacity for the fry pot (35 pounds or 55 pounds) is described on the serial plate (which is located inside the front door).
Remove the basket support frame when filling the fry pot with solid shortening.
When solid shortening is used, be careful not to bend, break, or twist the thin capillary wires of the sensing elements located in the fry pot.
Pack solid shortening into the zone below the tubes, all spaces between the tubes, and at least an inch above the top of the tubes before lighting the fryer. If any air spaces are left around the heat tube surfaces when the heat is turned on, the tube surfaces will become red hot, burn the solid shortening, weaken the fry pot, and could result in fire.
To prevent burning or scorching the solid shortening, keep the thermostat set at the lowest temperature until all the solid shortening between and above the tubes has been melted. Additional solid shortening can then be added until the desired frying depth has been reached.
Replace the basket support frame over the fry pot heat tubes.

CAUTION

NEVER ATTEMPT TO MELT A SOLID BLOCK OF SHORTENING ON THE TOP OF THE HEAT TUBES. NEVER START THE BURNERS WHEN THE FRY POT IS EMPTY

SHUTDOWN PROCEDURE

Standby: Turn knob on the combination gas valve to the “PILOT” position. At this setting, only the pilot burner will remain ignited.
Complete Shutdown: Turn knob on the combination gas valve clockwise, press down on the knob and continue to turn to the “OFF” position.

RELIGHTING

WARNING

In the event of a main burner ignition failure, a five minute purge period must be observed prior to reestablishing the ignition source.

Shut off all gas.
Wait five minutes.
Follow the “Lighting” procedure as described on page 11.

AUTOMATIC PILOT VALVE

The Automatic Pilot Valve provides an automatic safety shutoff for the fryer when the pilot flame is extinguished. When the pilot flame is burning, the valve is held open electromagnetically by the electrical current from a thermopile in the pilot flame. When the pilot flame goes out, generation of current ceases and the valve closes automatically.

HIGH LIMIT CONTROL

Avantco Equipment Floor Fryers are equipped with a secondary heat control that prevents the oil temperature from rising above 450°F. (Because of the accuracy tolerance of the sensor, the oil temperature may reach as high as 475°F.)
In the event the fryer shuts down due to this condition, the oil must be cooled to below 400°F before the pilot burner can be re-ignited. When the oil has cooled, use the “Lighting” procedure on page 11 to restore functionality.
If the problem persists, contact your Avantco Equipment Service Representative or the Avantco Equipment Service Department.

COOKING HINTS

USER TIPS

oil means that the temperature is too high, or that the oil has broken down.
Gum in fry pot denotes a need for thorough cleaning (see “Weekly Cleaning” on page 15)
Use different oil for oily foods (mackerel, nutmeg, etc.) than for foods with water-soluble flavors (potatoes, onions, etc.).
Taste oil for quality. Replace it regularly.
Poor oil cannot produce good food

CLEANING

Avantco Equipment is constructed with the best quality materials and is designed to provide durable service when properly maintained. To expect the best performance, your equipment must be maintained in good condition and cleaned daily. Naturally, the frequency and extent of cleaning depends on the amount and degree of usage.
Following daily and more extensive periodic maintenance procedures will increase the life of your equipment. |
Climatic conditions (e.g., salt air) may result in the need for more thorough and more frequent cleaning in order to keep equipment performing at optimal levels.

WARNING: BURN HAZARD

If necessary to move the fryer for cleaning, etc., drain oil first to avoid death or serious injury.

WARNING

If disconnection of the restraint is necessary to move the appliance for cleaning, etc., reconnect it when the appliance is moved to its originally installed position.

DAILY CLEANING

Turn thermostat knob to “OFF” position.
Place hot-oil safe container under the drain and drain the fry pot completely.
Remove the basket support frame (if applicable) and flush out any sediment remaining in the fry pot with a little hot oil.
Wipe off the basket support frame and the inside of the fry pot with a clean cloth.
CAUTION
SOME AREAS OF THE FRY POT MAY BE HOT!
Close drain valve and strain the oil back into the fry pot through several thicknesses of cheesecloth, or filter it back using a filter machine.
Replace the basket support frame (if applicable)
Add oil or shortening to MIN oil level mark on rear of fry pot.
To resume cooking, turn the combination gas valve knob to “ON” position

WEEKLY CLEANING

Follow steps 1 through 4 of the Daily Cleaning procedure (see previous section).
Close drain valve and fill fry pot with a solution of warm water and boil-out compound
Relight the fryer and bring the solution to a gentle boil for at least five minutes.
Turn off main burners and let the solution stand until the gum deposits are softened and the carbon spots and burned grease spots can be rubbed off.
Scrub the fry pot walls and heat tubes, then drain out fry pot and rinse it with clean water.
Refill the fry pot with clean water and boil again.
Turn off gas and drain and rinse well until clean.
Wipe dry with a clean cloth.
Refill as specified in the “Filling the Fry pot” section (see page 12)

MONTHLY CLEANING

Perform the Weekly Cleaning procedure (see previous section).
Clean around burner and orifices if lint has accumulated.
Visually check that burner carry-over ports are unobstructed.

CLEANING STAINLESS STEEL SURFACES

To remove normal dirt, grease and product residue from stainless steel, use ordinary soap and water (with or without detergent) applied with a sponge or cloth. Dry thoroughly with a clean cloth. Never use vinegar or any corrosive cleaner.
To remove grease and food splatter, or condensed vapors, that have baked on the equipment, apply cleanser to a damp cloth or sponge and rub cleanser on the metal in the direction of the polishing lines on the metal. Rubbing cleanser, as gently as possible, in the direction of the polished lines will not mar the finish of the stainless steel. NEVER RUB WITH A CIRCULAR MOTION. Soil and burnt deposits that do not respond to the above procedure can usually be removed by rubbing the surface with a scouring pad. DO NOT USE ORDINARY STEEL WOOL, as any particles left on the surface will rust and further spoil the appearance of the finish. NEVER USE A WIRE BRUSH, STEEL SCOURING PADS (EXCEPT STAINLESS), SCRAPER, FILE OR OTHER STEEL TOOLS. Surfaces that are marred collect dirt more rapidly and become more difficult to clean. Marring also increases the possibility of corrosion. Refinishing may then be required.
Darkened areas, called “heat tint,” sometimes appear on stainless steel surfaces where the area has been subjected to excessive heat. These darkened areas are caused by thickening of the protective surface of the stainless steel and are not harmful. Heat tint can normally be removed by the above cleaning techniques, but tint which does not respond to that procedure calls for a vigorous scouring in the direction of the polish lines, using a scouring pad in combination with a powdered cleanser. Heat tint action may be lessened by not applying or by reducing heat to equipment during slack periods.

SERVICE

FOR AUTHORIZED SERVICE TECHNICIANS ONLY!

NOTICE

Warranty will be void and the manufacturer is relieved of all liability if:
(A) Service work is performed by other than a qualified technician (see page 20-21 for details)
OR
(B) Other than approved Avantco Equipment replacement parts are installed.

WARNING

Adjustments and service work may be performed only by a qualified technician who is experience in, and knowledgeable with, the operation of commercial gas cooking equipment. However, to ensure your confidence, contact your Avantco Equipment Service Representative for liable service, dependable advice or other assistance, and for genuine factory parts.

All units are adjusted at the factory. In case of problems in operation at initial installation, check type of gas and manifold pressure and compare with information listed on the serial plate. A mill voltage circuit diagram is located inside the front door of the fryer, and also on page 19

CHECKING AND ADJUSTING MAIN BURNERS

The main burners should burn with a steady blue flame, and the inner cone of the flame from each port should be about ¾” long. The flame from each main burner should enter each heat tube without touching the front of the fry pot or the sides, top, or bottom of each tube.

CHECKING AND ADJUSTING PRESSURE REGULATOR

Turn thermostat “OFF” and combination gas valve knob to the “PILOT” setting.
Remove pressure tap plug from burner manifold located directly below the burners in the cabinet.
Install a fitting appropriate to connect a manometer.
Turn combination gas valve to “ON” position and thermostat to “ON.” The burners will ignite. Be certain that sufficient oil is covering the tubes.
With burners on, read manometer.
If the manometer does not read 4″ W.C. for natural gas, or 10″ W.C. for propane gas, adjust regulator.
Remove regulator adjustment screw cap (see diagram on page 18).
With small screwdriver rotate adjustment screw “CLOCKWISE” to increase or “COUNTERCLOCKWISE” to decrease pressure. Be sure to adjust with burners “ON.”
Turn thermostat “OFF” and set combination gas valve knob to “PILOT” position.
Remove manometer and replace pressure tap plug.
Replace adjustment screw cap.

CHECKING AND ADJUSTING CALIBRATION OF THERMOSTAT

All thermostat controls are carefully calibrated at the factory (i.e., the dial is properly set to control appliance temperatures accurately). Only a qualified appliance service technician should perform this adjustment.

To check appliance temperatures, use a thermocouple-type temperature test instrument or reliable thermometer. Place the thermocouple of test instrument or thermometer in the center of the fry pot.
Turn the control dial to the temperature setting requiring the greatest accuracy. Allow enough time for temperature to stabilize, or until several temperature readings are identical.
Recalibrate if setting and actual temperature differ by more than 10°F.
Remove dial from dial shaft “B.” Be careful that dial shaft does not rotate in either direction (which would change the dial setting).
Hold dial shaft “B” steady and with a screwdriver turn calibration screw “A” clockwise to decrease the temperature, or counterclockwise to increase the temperature.
Replace dial. Let the appliance operate until the temperature has stabilized before a final check is made to determine whether or not the calibration has been corrected.
Once correct, seal the calibration screw with glyptol.

CHECKING AND ADJUSTING AUTO SAFETY PILOT

The pilot flame should surround the thermopile for ½”. It must be large and sharp enough to cause the thermopile to glow a dull red, or sufficient to hold the safety valve open.

Checking and adjusting auto safety pilot
