(b) Slide the second deck onto the support angles on the sides and back.*
Figure #4
B. STEEL DECK INSTALLATION:
Steel decks come installed in the oven from the factory and no assembly is required. Before use,
remove all packing material and samples etc. from the baking chamber.
5. GAS AND ELECTRIC CONNECTIONS:
Propane gas units are not available in the European Community Countries.
(a) The appliance when installed, must be electrically grounded in accordance with local codes and/or
the latest edition of the National Electric Code ANSI/NFPA 70 in USA (Canadian Electric Code CSA
C22.2 in Canada).
(b) In Europe, appliance must be connected by an earthing cable to all other units in the complete
installation and thence to an independent earth connection in compliance with EN 60335-1 and/or local
codes
(c) The ovens should not be installed on the same line with space heaters, boilers or other gas
equipment with high intermittent demand.
6

(d) Use a pipe joint compound that is resistant to the action of liquefied petroleum gases when making
gas connections.
(e) For Propane gas, use at least 1/2" (13 mm) pipe or tubing with a 5/8" (16 mm) inside diameter. For
Natural gas, use 3/4" (19 mm) pipe.
(f) The appliance must be isolated from the gas supply piping system by closing its manual shut-off
valve during any pressure testing of the gas supply piping system at test pressures equal to or less than
1/2" psig (3.45kpa).
(g) The appliance and its 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" psig (3.45kpa).
(h) The gas pressure regulator is part of the combination valve and is adjusted to yield a pressure of
3.5" water column (9mbar) for Natural Gas. If the oven is ordered for use on Propane Gas, the pressure
regulator in the combination valve is preset at the factory to yield a pressure of 10" water column (25
mbar). Units for use on Propane Gas are not available for European Community Countries.
(i) A separate shut-off valve for each oven must be provided. It should be as close as possible to the
place where the gas supply line goes into the oven. It must be located such that it is easily accessible.
(j) When stacking with another oven, two shut-off valves, one for each of the two ovens, must be
provided.
After the Gas Supply has been connected, it is extremely important to check all the piping for
leaks. Use a soap and water solution or a product expressly made for this purpose. Do not use
Matches, Candles or a flame etc to check leaks since these methods are extremely dangerous.
6. FLUE CONNECTION - VENTILATION:
(a) INSTALLATION UNDER VENTILATION HOOD (STANDARD):
If the oven is not vented directly and is installed under a collection hood, use the flue diverter (fig.1)
supplied. Local inspectors and ventilation and environmental specialists should be consulted so that the
design and the installation of the hood conforms to the local / municipal codes (see fig.3).
(b) DIRECT VENTING (Optional) – NOT AVAILABLE FOR EUROPEAN COMMUNITY COUNTRIES:
If direct venting, it is necessary to install a draft hood (fig.2). The flue pipe from the draft hood must not
run downwards at any point from the oven to the final outlet. It should always slant slightly upwards. For
best results it should rise straight up.
NOTE: Do not put a damper in the flue and do not connect a blower directly to the flue. If the
flue runs directly to the free air outside the building, use awind deflector or a UL listed vent cap at
the end of the flue pipe. Termination of the vent must be at least 2 feet above the highest part of the
roof within 10 feet (Ref: American Gas Association Catalog No. XH0474)

7. MAIN BURNER SAFETY PILOT OPERATION:
The purpose of the safety pilot system is to lock the gas supply to the main burner at the combination
valve, if for any reason the pilot burner is not lit. Oven should be relighted by following the steps given
below. However, in normal service, the pilot flame stays lit indefinitely, day and night or weekends. This
prolongs the life of the safety valve.
The safety pilot valve is in effect a two-stage control. After initial lighting, the pilot burner stays on
without the gas cock dial being held pressed in. After 1-2 minutes, the valve opens fully to let the gas
flow past the safety pilot valve into the burner system.
A. PILOT BURNER LIGHTING PROCEDURE:
(a) Partially depress and turn the gas cock dial to ‘OFF’(•) position.
(b) Wait for five minutes to allow gas, which may have accumulated in the burner compartment, to
escape.
(c)Turn gas cock dial to ‘PILOT’(*) position.
(d) Depress gas cock dial and light Pilot Burner. Hold in pressed position for about ½ minute (30
Seconds), and release the gas cock dial. The Pilot Burner should now remain lit.
If Pilot Burner fails to ignite or does not remain lit, repeat the steps (a) through (d).
B. PILOT BURNER FLAME ADJUSTMENT:
It is important to have the correct Pilot Burner Flame size as shown in Fig.5. If necessary, adjust
the Pilot Burner Flame by turning Pilot Adjust Screw (See fig. 6) clockwise to reduce or counter-
clockwise to increase.

8. BURNER OPERATION:
(a) MAIN BURNER:
After the pilot burner is ignited, when heat is desired, turn gas cock dial to ‘ON’ (Ù) position and set the
thermostat dial to the desired temperature. The oven burner flame should always have a blue
appearance. That indicates a good mixture of gas and air. When using LP gas, the flame will have a
blue-yellow appearance.
Should the Burner fail to light, check to see if there is a problem with the gas supply. If there are other
appliances on the same line, shut them off temporarily and see if the burner comes back on, or it
fluctuates as other gas appliances are turned on and off. That would indicate overloading of the gas
supply lines or a faulty gas pressure regulator. Contact an authorized Service Agency or your local Gas
Supply Company.
8

(b) AERATION AND BY-PASS FLAME ADJUSTMENT:
Flame and air mixer adjustments and the By-Pass Flame adjustment for the Main Burner are done at
the factory. These adjustments are sealed before the oven leaves the factory. Contact an authorized
Service Agency if you need help.
9. THERMOSTAT CALIBRATION:
No attempt should be made to calibrate the thermostat because it is accurately calibrated and sealed by
the manufacturer. Contact an authorized Service Agency if you need help.
10. HEAT BAFFLE ASSEMBLY:
The Heat Baffle Assembly distributes the heat evenly below the baking deck. It must be in good
condition in order to be effective. A damaged Heat Baffle will adversely affect the oven performance.
Check it periodically and replace as necessary.
II. OPERATING INSTRUCTIONS
NOTE: Only Pizza and Bread Products can have direct contact with Ceramic Decks. All other
food products must be placed in a pan or containers to avoid direct contact with Ceramic Decks.
If gas odor is detected at any time, immediately shut-off the gas supply valve for the oven. Do not
permit any open flames in the area of the oven. Immediately contact an authorized Service
Agency or your local Gas Supply Company.
Initial heating of the oven must be done in a well-ventilated area as it may generate smoke or
fumes. Over exposure to smoke or fumes may cause nausea or dizziness
1. LIGHTING PROCEDURE:
(a) Light the Main Burner following the instructions in Section 7A of the Installation Instructions.
2. BREAKING IN:
It is important to break-in, to dry out the deck and the insulation, before baking in a new oven:
(a) Allow the oven to warm to 300°F(150°C) for 5 hours or at least till all the smoke and fumes have
disappeared. The smoke and fumes are from the moisture in the deck and insulation and a light coat of
oil.
(b) Set the thermostat at least 50°F (10°C) lower than your baking temperature.
(c) Pre-heat the oven for 1 to 1½ hours before use.
(d) After pre-heating, raise the temperature to your baking temperature.
(e) Experiment baking until you get the feel of the oven and the speed of the bake.
3. BAKING:
Pizza can be baked on the deck, on a screen or in a pan. When you determine the combination of
method, ingredients and temperature that gives the right bake for your crust, sauce and cheese
combination and your customer’s taste, mark and keep it.
Deck baking refers to baking Pizza directly on the deck. Generally it is a thin product that requires
temperature of at least 550°F (290°C).
Screen baking refers to baking Pizza on a screen. The screen lifts the Pizza off the deck. The screen
may be removed near the end of the bake time to give the bottom of the Pizza crispier crust and a
darker color. Bake temperatures range from 500°F (260°C) to 550°F (290°C).
Pan baking refers to baking Pizza in pans. Crusts can be thick or thin and toppings range from light to
heavy. Bake temperatures for pan baking range from 450°F (235°C) to 500°F (260°C).
4. RECOMMENDED OPERATING PROCEDURE:
9
It is very important that at the end of day’s operation, the gas cock dial of the Main Burner is
turned to the pilot position, leaving only the pilot burner ‘ON’ overnight.

Preheating:
(a) Turn the gas cock dial of the main burner to the ‘ON’ position.
(b) Preheat the oven for 1 to 1 ½ hours at 50°F (10°C) lower than your baking temperature.
Baking:
(a) When ready to bake, raise the thermostat setting to your baking temperature.
5. HELPFUL HINTS:
(a) If the oven is up to Pizza baking temperature and has not been used for a while, there is a tendency
for the baking deck to get hotter. In this condition, when you put in one Pizza, TURN THE
THERMOSTAT UP, so that the main burner flame is burning at it’s fullest, providing the extra heat
needed to balance the bottom heat. The thermostat should be turned down back to the normal setting
as soon as you have baked the Pizza.
(b) Top section takes longer to bake as compared to the bottom section. Allow 1 to 2 minutes extra bake
time for the items placed there.
(c) Frequently scrape and brush off decks to remove burnt residue which can cause an “off” flavor and
bake times to increase.
(d) Heavily topped Pizza or Pan Pizza requires lower bake temperatures and longer bake times as
compared to a regular thin Pizza with light toppings.
(e) Bubbles in fresh dough indicate under proofed or cold product. Allow the dough balls to proof to
double in size and warm temperature before baking.
(f) Any type of Pan or Screen may be used in this oven. When choosing pans, be sure to pick a pan
which is closest in height of your product. Dark color pans and screens transfer heat better than
light colored aluminum pans or screens. They must be seasoned before use.
III. CLEANING AND MAINTENANCE
This appliance must be serviced by an Authorized Service Technician only. Disconnect the
power supply before cleaning or servicing the oven.
Regular and thorough cleaning will help to keep the ovens operating properly. If service is required,
contact an Authorized Service Agency, your dealer or the factory to obtain a qualified technician for the
required maintenance/service.
1A. OVEN EXTERIOR:
(a) Deposits of baked-on splatter and grease, or discoloration may be removed with the stainless steel
cleaner sample supplied or by using any commercial cleaner recommended for stainless steel. Bakers
Pride offers a stainless steel cleaner expressly for this purpose. RINSE WELL
(b) A thin coat of light oil will add to the appearance of the oven.
NOTE: Apply stainless steel cleanser only when the oven is cold. Always rub with the grains and
apply very light pressure.
1B. PAINTED SURFACES:
a) Washing with mild soap and water solution is adequate to keep the painted surfaces clean.
b) Apply a thin coat of oil to protect and enhance the finish
2. CONTROL PANEL:
Every six months (more frequently if the oven is used heavily) the bottom door spring mechanism and all
moving parts must be inspected for wear.
Do not apply grease to spring lever shoulder bolt, spring roller or the door rod and the door pin.
They have a self-lubricating insert that will be damaged if lubricated.
3. FLUE VENT:
Ventilation system must be inspected every six months and maintained clean and free of obstructions.
10

4. OVEN INTERIOR:
Clean the oven interior only when the oven is cold. Use only the detergent solutions and cleaners that
meet the national and / or local codes.
(a) BAKING CHAMBER:
Clean the ceiling and the walls of the baking chamber with a mild soap and water solution. Do not use
oven cleaners, caustic solutions or mechanical means as they will damage the interior
aluminized surface.
(b) BAKING DECKS:
The baking decks are heavy and fragile. They should be handled carefully.
The baking decks should be cleaned by using a long-handled scraper and stiff wire brush. At the end of
each day, turn the thermostat up to its maximum setting and let the oven sit at that temperature for at
least ½ hour. This will burn off the food spilled onto the baking decks during day’s production and turn it
into ash. This ash can be brushed off the next day before turning the oven on. The baking decks should
be scraped and brushed during the day also to help keep them clean. To remove excessive crumbs or
carbon, the baking decks and the oven cavity may vacuumed when the oven is cold. Do not use water
or other liquids on the baking decks as that may cause them to crack. After long use, heavily soiled
baking decks may be cleaned by turning over after scraping down and brushing off. This will burn off the
heavily soiled side of the baking decks. This procedure may be repeated as needed.
(c) BURNER COMPARTMENT:
Vacuum out any carbon, crumbs or residue in the burner compartment and all around the doors. The
holes and louvers on the outer surfaces of the oven must be kept free of obstructions to allow free
movement of air into the controls and for proper combustion. The burner ports and crossover holes
should be kept free of carbon and other deposits.
