DELIVERY INFORMATION

PRE-SHIPPING INFORMATION

The information below is designed to prepare the general contractor for the arrival of the
HARDT Inferno Rotisserie. Please ensure that the appropriate personnel have reviewed
this information prior to the rotisserie’s arrival.

It is very important to note that the rotisserie crate should be received as “Subject
to Verification” (i.e., write it on the waybill when signing for the shipment), as you
will only be uncrating it after the transport truck has left. This will allow you the
opportunity to make a claim against the transport firm should the rotisserie or its
components have been damaged in transit.

To remove the rotisserie from the truck you will require a forklift. The transport company
will call 24 hours prior to delivery to allow for preparation.

TAKE CARE WHEN HANDLING THE CRATE AS IT IS TOP HEAVY.

THE UNIT SHOULD BE DRAGGED AS LITTLE AS POSSIBLE AS THIS MAY CAUSE
VIBRATIONS THAT MAY DAMAGE THE ELECTRONIC IGNITION SYSTEM.

DIMENSIONS / WEIGHTS:

Crated with Accessories: 88” H x 48” W x 44” D Approx. 1130 lbs
FOB Montreal.

The rotisserie door may need to be removed from the crate for it to enter through a stan­dard doorway. See the SPECIFICATIONS section for precise dimensions.

Please do not uncrate the rotisserie until ready to install in order to prevent the loss of
any parts or accessories shipped with the unit. An inventory checklist is provided on
page 12 to help you verify the contents of the shipment. Call HARDT if you have any
questions.

To connect the rotisserie once it is in position you will require:

1) AN ELECTRICIAN

INSTALLATION INFORMATION

ORDER OF INSTALLATION

Warranty is conditional on proper installation as per the instructions in this section.
Should the rotisserie be improperly installed and service be performed, all charges will
be invoiced to the individual who requested the service. Please call our Customer
Service department if you have any questions whatsoever.

1. Install the ventilation hood or the ducting for a direct venting setup.

2. Place the HARDT Inferno rotisserie in position as described on the following page.

3. Connect the gas, electricity, and plumbing to the rotisserie.

VENTING INFORMATION

The INFERNO rotisserie is designed to be direct vented or to be used with a hood /
canopy type vent. Please contact a hood supplier that manufactures hoods that conform
to YOUR design as well as local codes. In either case the INFERNO rotisserie is
equipped with an 18” long by 8” diameter flue riser that is necessary for proper opera­tion.

The HARDT INFERNO rotisserie must vent freely. Do not install the hood and
make-up air in a way that air is being blown into or pulled out of the rotisserie.
Either of these events will greatly affect the rotisserie’s operation. The hood
should remove the exhaust gases without disturbing the air within the rotisserie.

Hood Specification Recommendations

We recommend a Type 1 / Class Agrease hood with filters. It is normally equipped with
a fire suppression system. Per local authorities and codes, NFPA 96 recommends that
all rotisseries that produce grease laden vapors should be vented to a Type 1 / Class A
hood. Other equipment that would fall into this category would be fryers and griddles.

The hood should have at least 12" of overhang canopy on sides and front (this may vary
as per local code).

The lower lip of the canopy should be no more than 6 inches above the top of the
unit. If the clearance exceeds this dimension it may allow drafts which will
interfere with the unit's operation and efficiency.

If the unit is installed on casters, so as to be mobile for service, ensure that the
fire suppression nozzles do not prevent it from moving.

Exhaust

950 CFM is recommended for INFERNO 24 model rotisseries.

Supply

When a plenum is used for make up air, the supply riser should be 600 CFM.

Balancing Hood Information

Balance the hood as well as the store environment, as per NFPA # 96.

POSITIONING OF THE ROTISSERIE

Do not locate the rotisserie in an area where the right (control) side is next to fry­ers, broilers or any other appliance that emits grease, smoke, humidity, flour etc.

As the venturi for the burner is behind the control panel, precautions should be
taken to prevent the above mentioned particles from entering the burner and caus­ing it to malfunction.

Once the hood installation has been completed the rotisserie can be placed in position.
To operate properly, the rotisserie should be positioned on a level surface in a draft-free
area where the temperatures remain above 45 degrees Fahrenheit.

To allow for sufficient cooling the required minimum clearances to combustible and non­combustible surfaces are:

Left (non-motor) side: 3”
Back: 3”
Right (motor) side: 3” (12” if unit is not equipped with casters

. This is the minimum

necessary for adequate access to the service compartment)

Failure to conform to minimum clearances may result in service not being able to
be performed!

A clearance of less than 12” on the control side requires the use of casters and
quick disconnect connections for both the gas and the water supplies.

ON UNITS EQUIPPED WITH CASTERS, THE FRONT 2 CASTERS ARE EQUIPPED
WITH BRAKES. THESE SHOULD BE KEPT LOCKED TO PREVENT THE
ROTISSERIE FROM BEING MOVED ACCIDENTALLY.

INSTALLATION OF WATER SUPPLY

When a direct connection to a permanent water supply is desired the water source
should be connected to the copper pipe on the rotisserie. Avalve (not supplied) should
be installed between the copper pipe on the rotisserie and the water supply.

When installing a permanent water supply, make sure that the main valve is
installed in an easily accessible location, preferably at the front of the rotisserie.

For a manual supply of water, either by hose or bucket, the copper pipe must be plugged.
In either case it is recommended to use hot water as it reduces warm-up time and

facilitates cleaning.

Local ordinances may require a backflow prevention device. Consult the authority having
jurisdiction to determine what regulations are in force for appliances of this type.

UNITS WITH CASTERS

As an option the unit may be ordered with casters. When supplied with this option it is
required that the rotisserie be equipped with ‘Quick Disconnect’ gas installation hard­ware. In this case connect the rotisserie to the gas supply using the instructions sup­plied in the ‘Quick Disconnect’ kit.

When using the ‘Quick Disconnect’ hardware, the rotisserie must be equipped with a
connector that complies with the Standard for Connectors for Movable Gas Appliances,
ANSI Z21.69 or Connectors for Movable Gas Appliances, CAN/CGA-6.16

The Dormont ‘Quick Disconnect’ kit which may be purchased from Hardt is a quick-dis­connect device that complies with the Standard for Quick Disconnect Devices for Use
with Gas Fuel, CAN1-6.9.

A RESTRAINING DEVICE MUST BE INSTALLED SUCH THAT THE ROTISSERIE
MOVEMENT IS LIMITED WITHOUT RELYING ON THE CONNECTOR AND THE
QUICK DISCONNECT DEVICE OR ITS ASSOCIATED PIPING. The restraining cable
for the Dormont kit attaches at the point shown in the diagram on page 13.

All gas installations must be performed by a licensed professional. Check local ordi­nances for applicable regulations.

INSTALLATION OF DRAIN

There are two holes in the rotisserie's water pan. One is for the drain and the other is for
the overflow. The drain hole is the one located at the back of the rotisserie's water pan.

Underneath the rotisserie place the two rubber washers onto the flat portion of the drain
elbow and line up the drain elbow with the back hole of the rotisserie's water pan.

Inside the rotisserie, insert the strainer into the back hole of the water pan and tighten
the strainer into the drain elbow.

Weld the drain valve in the location most accessible to the employees.

When installing a rotisserie equipped with casters, make sure that for it to remain
mobile for servicing the drain is not hard plumbed into the floor.

Please consult the authority having jurisdiction to determine what regulations are in force
regarding the disposal of grease laden water.

INSTALLATION OF OVERFLOW

The overflow is located in the front of the two holes in the rotisserie's water pan.
Underneath the rotisserie, place two rubber washers onto the flat portion of the overflow

drain elbow and line it up with the front hole of the rotisserie's water pan.
Inside the rotisserie insert the overflow strainer into the front hole of the water pan and

tighten it into the overflow drain elbow. (If the overflow is connected to the drain pipe it
must join the drain only after the drain valve.)

Please consult the authority having jurisdiction to determine what regulations are in force
regarding the disposal of grease laden water.

OPERATION

SHOULD THE ROTISSERIE NOT LIGHT ON THE FIRST TRY, OPEN THE DOOR AND
ALLOW A ONE MINUTE PERIOD BEFORE RELIGHTING.

PRIOR TO STARTING THE ROTISSERIE

It is recommended to wrap the center shaft in aluminum foil. This will facilitate cleanup
of the rotisserie after daily use.

Close the drain valve and fill the drip pan, preferably with hot water. The water in the
rotisserie will serve to diffuse the drippings and facilitate cleanup as well as provide mois­ture during the cooking process.

MORNING STARTUP

Open the rotisserie door and verify that:

1. The thermometer probe is clean. Clean if necessary.

2. The thermostat probe is clean. Clean if necessary.

3. The light lenses are clean. Clean if necessary.

4. The ‘ATEND OF THE DAY’ cleaning was performed properly. If not done, do it now.

PREHEATING

1. Verify that the door is closed.

2. Set the thermostat to the OFF position.

(This is to ensure that initially only the rear burner lights.)

3. Set the timer to 30 minutes.

4. Pull the MAIN ON /OFF switch (Red Button) to the “ON” position.

(The back burner will light.)

5. After approximately 5 minutes set the thermostat to the temperature setting at which
you will be cooking.

(The front burner will light.)

Allow the rotisserie to become preheated to the desired temperature. Sufficient pre­heating minimizes and excessive temperature drop while the rotisserie is being loaded,
and prolongation of the cooking time of the first load.

While the rotisserie is being preheated, prepare the product.

OPERATION

NEVER STICK YOUR HANDS OR ANY OTHER OBJECTS INTO THE ROTATING
DRIVE WHEN LOADING SKEWERS.

ALWAYS USE INSULATED OVEN MITTS OR SKEWER FORKS WHEN HANDLING
SKEWERS NEAR THE HOT ROTISSERIE.

1. When the oven is preheated, load the desired amount of skewers into the rotisserie.

2. Set the thermostat to the desired temperature setting.

3. Set the timer to the desired cooking duration.

4. At the end of the cooking cycle, measure the internal temperature of the chickens. It
should be 185 degrees F.

INSERTION OF SKEWERS

CROSS CONTAMINATION IS VERY DANGEROUS!
DO NOT LOAD FRESH PRODUCT INTO THE ROTISSERIE UNTIL THE COOKING
CYCLE IS COMPLETE AND ALL THE COOKED PRODUCT HAS BEEN REMOVED
FROM THE ROTISSERIE.

When the rotisserie has reached its operating temperature the skewers can be loaded
into the rotisserie.

Opening the door will cause the burner to shut off and the drive to stop rotating. The
Manual Switch (Green button, located on the front of the control panel) actuates the drive
mechanism without igniting the burner. Press and hold this switch until the desired
socket on the drive drum is easily accessible at the front of the rotisserie.

The above sketch illustrates the insertion of the loaded skewers into the drive sockets.

A) The pointed end (1) of the skewer is inserted into the hole (3) in the support plate at

the left side of the rotisserie.

B) The hexagonal end (2) is then raised and inserted into the drive socket slot (4) in the

right hand drive drum.

C) The hexagonal end (2) must be slid into the socket as far to the right as possible to

make certain that the shoulder on the pointed end is inside the face of the support
plate. This prevents the skewer from slipping out of the drive drum socket.

IF YOU HAVE PURCHASED BASKETS OR ROAST SKEWERS, YOU MAY HAVE TO
SKIP SOCKETS WHEN COOKING . PLEASE CONTACT OUR FIELD APPLICA TIONS
TEAM AT 1-800-387-6847 TO DISCUSS YOUR PARTICULAR SITUATION.

NEVER PLACE THE SKEWERS (OR BASKETS) INTO THE ROTISSERIE WITH THE
GROOVE IN THE SKEWER’S POINTED END RESTING ON THE SUPPORT PLATE.
THE GROOVE IS ONLY FOR HANGING THE SKEWER ON THE OPTIONAL WALL
MOUNTED SKEWER RACK.

To prevent unnecessary losses of heat that will increase cooking time, the doors
should not be opened until the end of the cooking cycle. The end of the cooking
cycle is indicated by the sound of the ‘end of cook’ buzzer.

REMOVAL OF SKEWERS

To remove the skewers, open the doors to stop the skewer rotation and shut off the
flame. Use the Manual Switch (Green button) to activate the drive motor alone and bring
the desired skewer to the front and center of the door opening where it is readily acces­sible. Reverse the insertion process by raising the pointed end slightly so that the shoul­der is level with the hole in the support plate and push the skewer to the left until the
hexagonal end is free from the drive socket. Remove the skewer. If the rotisserie will
not be used it should be cleaned as described in the “CLEANING” section.

We recommend leaving the doors OPEN when the rotisserie is not in use. If the
doors remains closed, as the rotisserie cools, humidity will condense around the
igniter causing the rotisserie to go into ‘Safety Lockout’.

IN THE EVENT OF A PROLONGED POWER FAILURE, THE ROTISSERIE MUST BE
SHUT OFF BY PUSHING IN THE MAIN ON/OFF SWITCH (RED BUTTON).

MAINTENANCE

Your HARDT rotisserie was built using only the highest quality products. All bushings,
as well as the complete drive train, are permanently lubricated and do not require any
greasing or oiling. The most important maintenance is the daily cleaning as described
in the sections below.

DISCONNECT POWER SUPPLY TO THE ROTISSERIE BEFORE SERVICING.

ALWA YS SHUT-OFF THE CIRCUIT BREAKER WHEN CLEANING INSIDE THE ROTISSERIE.

CLEANING THROUGHOUT THE DAY

It is highly recommended to clean the rotisserie glass with a wet cloth at the end of each
cooking cycle. This procedure keeps the glass clean without scratching it. Depending
on the volume of product cooked, changing the water during the day may be desired.

CLEANING AT THE END OF THE DAY

OPEN THE DOOR AND ALLOW THE ROTISSERIE TO COOL DOWN UNTIL IT IS
SAFE TO TOUCH.

NEVER SPRAY CHEMICALS OR LIQUIDS OF ANY KIND (INCLUDING WATER) IN
THE DIRECTION OF THE BURNER OR THE IGNITER (INSIDE, UPPER FRONT), THE
CERAMIC RADIANTS OR THE EXTERIOR OF THE ROTISSERIE. Should any liq­uids come in contact with the burner while it is still hot, the ceramics in the burn­er might crack and the burner will have to be replaced. If chemicals come in con­tact with the igniter, the igniter will corrode, the rotisserie will malfunction, and the
igniter will have to be replaced. To avoid damage, when cleaning the drive plate
or applying degreaser, first do the bottom half of the drive plate, then rotate the
drive halfway by pushing the green button, and then do the other half.

Hang the cleaning shield that is supplied with each rotisserie on the inside back wall of
the unit so that it protects the rear burner . It should be positioned closest to the right side
to protect the igniter from water or chemical spray. Remove the aluminum foil used to
wrap the center shaft. Spray an approved degreaser on the interior of the warm rotis­serie. Allow it to work and rinse clean.

Spray the area in and around the drive sockets and the hole in the drive ring with
an approved degreaser.

After the grease melts, use the small bristle brush to remove any buildup from around
and inside the sockets, then rinse with water . In doing this simple operation you will elim­inate the blockage of the sockets due to the accumulation of dry hard carbon.

The glass on both the doors as well as the glass protecting the oven’s interior light should
be cleaned daily as the buildup of burnt carbon is very difficult to remove from tempered
glass.

The thermostat and thermometer probes must be wiped clean as carbon buildup will
cause improper readings.

The igniters should be inspected at this time also to ensure that they are free of carbon
and grease buildup. If they are dirty use a dry paper towel to wipe them clean.

AVOID USING SCOURING PADS OR CLEANERS WITH GRIT AS TEMPERED
GLASS IS EASILY SCRATCHED.

After cleaning, always leave the door open to allow the humidity to escape as it
will condense around the igniter causing starting problems the next morning.

If parts returned are found to have not been adequately maintained, they will NOT be
covered by our warranty plan. Warranty does not cover damage caused by the above
or any other misuse.

MAINTENANCE EVERY MONTH

Once a month the rear burner should be cleaned.

1) Make sure the unit is cool to work on, that there is no water in the waterpan and that
the power is turned off (either at the switch on the wall controlling the unit or on the
circuit breaker of the machine, found just beneath the waterpan near the control
panel). We recommend you place a sheet of cardboard in the waterpan to prevent
it being scratched or damaged when the pieces are being moved.

2) Remove the ceramic logs from the rear grate. Be careful, they are fragile. (If they
are covered with grease, simply turn them around when replacing them. The next
day you can turn them back and they will have been cleaned by the flame.)

3) The rear grate must be lifted over the lip of the back of the waterpan, then slid under
the spit support and drive plate rings and out the front of the rotisserie. Once out, any
grease deposits can be scraped off with a scraper.

4) Use a step-stool to elevate yourself so you can easily inspect the back burner to see
if all the holes are open. If some are clogged, use a stiff bristle brush on the surface
to loosen the debris and a long straight object (such as a coat hanger, paper clip or
small jewelers screwdriver) to clear any blocked holes. This is the area in the unit
that acts as a flame sensor.

5) The grate can now be re-installed.

7) Replace the ceramic logs (as shown in the diagram on page 19). They need to be
angled at a 60 degree angle starting with a large one, then a small one etc, from left
to right.

8) The job is complete, remove the cardboard and turn the power switch or circuit­breaker back on. Clean up any debris from the area in and around the rotisserie as
it may block the drain.

MAINTENANCE EVERY TWO MONTHS

Every two months, when the oven is cool, remove the ceramic logs and their support.
Verify that the rear burner is clean and that its holes are not blocked. If any of the burn­er holes are blocked, use a thin metal rod (such as a coat hanger) to clear them.

Unscrew the external thermometer and check its calibration. When the probe is
immersed in the boiling water the dial should read 212°F.

Verify that the cleaning of the inside of the drive sockets is being properly done. Clean
if necessary. Black carbon buildup around the exterior of the sockets is the first sign of
improper or insufficient cleaning.

TROUBLESHOOTING

PROBLEM

Rotisserie does not operate when Main ON/OFF Switch (Red button) is pulled.

SOLUTION

A) Check rotisserie electrical cord is connected properly.
B) Check if the circuit breaker is in the ‘ON’ position.
C) If both A and B are OK, call our service department.

PROBLEM

Main ON/OFF switch (Red button) is pulled, drive drum rotates but after 11 seconds the
alarm buzzer sounds. Rotisserie has gone into SAFETY LOCKOUT.

SOLUTION

A) Verify that the startup procedure is being followed correctly.
B) If the rotisserie again goes into safety lockout, turn the rotisserie “OFF” by pushing

in the Main ON/OFF Switch (Red button). Open the door of the rotisserie. If the door
has been closed all night, humidity may have condensed around the igniter. Get a
paper towel and gently clean the igniter. This procedure will clean and de-humidify
the ignition. Turn the rotisserie “ON” by pulling the Main ON/OFF Switch.

C) If the rotisserie again goes into safety lockout note which burner (front or back) does

not ignite or stay lit. T urn the rotisserie OFF by pushing in the Main ON/OFF Switch.
Depending on which burner is not working check the gap at the tip of the appropriate
igniter. The gap should be between 1/8" and 3/16” in size as shown below. Verify
that the igniter and the area of the burner that is near the igniter are clean.

D) If the rotisserie again goes into safety lockout, switch the rotisserie OFF for 1 minute.

Check that the gas valve on the rotisserie and that the main gas supply valve are
both open. To check the main gas supply valve, try another gas powered appliance
connected to the same line. Pull the Main ON/OFF Switch to turn the rotisserie ON.

PROBLEM

Halogen light bulb is burned out.

SOLUTION

Unscrew (counterclockwise) the protective glass lens of the defective bulb and pull out
the bulb.

The Halogen bulbs should not be touched with bare fingers as the oil from your
hands will reduce the life of the bulb. If the bulb is accidentally touched it should
be cleaned with rubbing alcohol (isopropyl alcohol).
When shipped, the service bulbs are in a plastic bag. One should use clean gloves
or a plastic bag or wrapper when taking a bulb out of the bag and inserting it into
the lamp holder.

To replace the Halogen light, insert the bulb into its socket using the described handling
method. Once it is in place screw the protective glass lens over the bulb.

If problems other than those described above arise, DO NOT ATTEMPT TO FIX THEM
YOURSELVES. For any technical assistance, please contact a HARDT Customer
Service Representative at the above Customer Service 1-800 number, available 24
hours per day, 7 days per week.
