OVEN MUST BE KEPT CLEAR OF COMBUSTIBLES AT ALL TIMES
After the gas supply has been connected to your appliance, it is extremely important to
check piping for possible leaks. To do this, use soap and water solution or solutions
which are expressly made for this purpose. DO NOT USE matches, candles, flames
or other sources of ignition since these methods are extremely dangerous. Post in a
prominent location instructions to be followed in the event you smell gas. Obtain
these instructions from your local gas supplier.
For Your Safety: Do not store or use flammable liquids or vapors in the vicinity
of this or any other appliance.
Warning: Improper installation, adjustment, alteration, service or maintenance can
cause property damage, injury or death. Read the Installation, Operating and
Maintenance instructions thoroughly before installing or servicing this equipment.
Initial heating of this oven may generate smoke or fumes and must be done in a well

INSTALLATION
RECEIVING
Check the package for damage. If any damage is visible you should mark the bill of lading you sign
that there may be concealed damage. Insure the container is upright. If the container is not upright major damage can occur to your appliance. If damage is discovered, do not refuse delivery. Contact the
carrier and file appropriate freight claims. Do not contact the manufacturer. Shipping damage claims
are to be resolved between the customer, shipping carrier and dealer. The manufacturer may assist in
resolving any such claims, but such assistance does not relieve you of your responsibility.
Read the notice on the outside carton regarding damage in transit. Damage discovered after opening
the shipping container and inspecting the oven is “CONCEALED DAMAGE” and the carrier must be
notified immediately to send an inspector and also to furnish forms for the customer’s claim.
When the oven arrives it should consist of:
a. A crate or carton containing your new oven
b. A carton containing four legs with mounting hardware
c. A strapped skid containing baking decks and (if ordered) ceiling tiles
Place the oven and parts as close to the final installation area as possible. Your oven is normally
packed on its side or back. Leave it in this position while unpacking. The skid may be left in place
during unpacking and may be convenient in further handling. Unpack your oven carefully to avoid
damage. If concealed damage is found refer to the instructions above.

INSTALLATION
MOUNT THE LEGS
Use proper lifting equipment. Due to the oven’s size and weight a rolling lift jack, air sled or pallette
jack may be required.
Legs are shipped in a separate container with mounting hardware.
Bolt two legs to the upper corners of the oven. Tighten in place.
Use proper lifting equipment. Lower the oven down so that the two bolted legs rest on the floor.
Use proper lifting equipment. Raise the second end of the oven slightly higher than the height of the
legs. Remove the skid and support the frame of the oven.
Mount the remaining two legs and bolt in place.
Use proper lifting equipment. Lift oven and remove all supports. Move oven into its final location.
OPTIONAL CASTERS
When optional casters are ordered there will be two with locks and two without locks.
Locking casters to be mounted at the two front corners of the oven.
Appliances mounted on casters must be connected to the building framing to prevent stress on electrical and gas connections.
NOTE: Installation should be made with a connector that complies with the latest edition of the Standard for Connectors for Movable Gas Appliances ANSI Z21.69 in the USA and CAN CGA-6.16 in
Canada and a quick disconnect device that complies with the latest edition of the Standard for Quick
Disconnect Devices for use with gas fuel ANSI Z21.41 in the USA and CAN CGA 1-6.9 in Canada an
adequate means must be provided to limit the movement of the appliance without depending on the
connector and any quick disconnect device or its associated piping. The restraint should be attached to
the rear legs of the oven on which casters are mounted. If disconnection of the restraint is required for
service the restraint must be reconnected after the appliance is returned to its normally installed position.
Minimum Clearances:
Left Side from Combustible construction: 3” [75 mm] from Non-Combustible construction: 0
Right Side from Combustible construction: 1” [25 mm] from Non-Combustible construction: 0
Rear from Combustible construction: 3” [75 mm] from Non-Combustible construction: 2” [50 mm]
DECK INSTALLATION
Remove all packing material, samples, shims, etc. from the baking chamber leaving the metal hearth
sheets on the baking chamber floor. Make sure the sheets are arranged to cover the whole bottom of
the chamber.
Depending on the model, two, three, or four baking hearth stones are required for the cooking deck.
The hearth stones are heavy and fragile. Careful handling is required for personal safety and to insure
proper performance.
Slide the first stone into the baking chamber. Push it as far back as possible. Push it to one side as far
as possible.
Slide additional stones into the baking chamber similarly. If more than two stones are required for the
oven cavity install the side stones first to insure they are properly positioned into the cavity corners behind the door frame as required.
Seams should be closed tightly by moving hearth stones against each other.
Use of metal shims may be required to level the stones.
The use of steel wedges between the hearth stones and cavity sides may be required. Care must be exercised if wedges are installed along side walls of the cavity to insure the operation of the vent slides is
not adversely affected by too much side pressure causing them to bind.
10
INSTALLATION
On models that include them install the hearth trim strip between the front of the baking hearth stones
and the door frame.
After curing and use, new stones may require re-leveling. This is the responsibility of the owner and
not the manufacturer.

BUTT TIGHT
IN-BETWEEN
SEAMS
CEILING TILES
Some models have the option of having a hearth lined ceiling. These tiles will be packed separately
from the oven, may be in the same container as the baking deck tiles.
For Il Forno models there are multiple square tiles that get installed into the top supports by tipping at
an angle, inserting the edge above the support rail toward the center, setting one edge along the support
rail along the side of the cavity and letting the tipped up edge come down to rest on the center support
rail. Center tiles are installed the same way.
For deck ovens a long narrow ceiling stone will be inserted at a cut-out in the front edge along the door
opening. Set the rear end up over the ledge along the back of the cavity. Swing the front edge up
through the cut-out and slide it to the left or right for positioning.
11
INSTALLATION
GAS CONNECTIONS
Your oven installation must conform to local codes. In the absence of local codes it must comply with
National Codes.
The type of gas the oven is equipped for is stamped on the rating plate. Connect ovens marked “NAT”
only to natural gas supplies. Connect ovens marked “LP” only to propane gas supplies.
Before connecting oven the gas supply should be inspected by your gas supplier or local authorities to
insure sufficient gas flow, pressure and meter size.
If the gas supply line is greater than 1/2 PSI [3.45 kPa] a step-down regulator is required.
The gas inlet connection for all ovens is 3/4” NPT.
Each oven deck requires its own gas shut-off that is end-user supplied.
All pipe joints must be sealed with pipe thread sealant rated for use with LP gas supplies.
Before use all pipe joints must be inspected for leaks. Use a soap and water solution or a product expressly made for this purpose. Do NOT use matches, candles or flames to check for leaks as these
methods are extremely dangerous.
The oven and its shut-off valve must be disconnected from the gas supply piping during any pressure
testing in excess of 1/2 PSI [3.45 kPa].
The oven must be isolated from the gas supply by manual shut-off valve during any pressure testing at
levels equal or less than 1/2 PSI [3.45 kPa].
Only Natural Gas equipped models are available in European Community Countries
In MASSECHUSETTS all gas products must be installed by a Massachusetts licensed plumber or gas
fitter. Ventilation hoods must be installed in accordance with NFPA-96, current edition, with interlocks as described in that standard.
WARNING: Installation must conform with local codes and/or with the latest edition
of the National Fuel Code ANSI Z223.1 Natural Gas Installation code in the USA or
CAN/CGA-B149.1 or the Propane Installation code, CAN/CGA-B 149.2 in Canada.
WARNING: This appliance must be installed by a competent person in accordance
with rules in force. In the U.K. Corgi registered installers (including the regions of
British Gas) undertake to work to safe and satisfactory standards. This appliance must
be installed in accordance with the current Gas Safety (Installation and Use) Regulations and the relevant Building Regulations/IEE Regulations. Detailed recommendations are contained in the British Standard Codes of Practice BS 6172, BS 5440: Part
2 and BS 6891.
12
INSTALLATION
VENTILLATION
All gas appliances must be ventilated. Proper air supply and ventilation is essential for personal safety
and proper operation. Improper ventillation can also cause poor baking results. Consult NPFA 96 as
well as local codes regarding ventilation requirements.
Ventilation is the requirement of the end user and you are strongly recommended to use an HVAC specialist to design a proper system for your kitchen.
Traditional installations will be under a canopy hood. This hood should be a minimum of 78 in [1950
mm] from the floor and extend beyond the footprint of the oven by 4” - 6” [100 mm - 150mm] on all
sides. The flue diverter included with your oven should be used.
For many installations a direct vent option is an option. A draft hood connected to your oven flue exit
is necessary. This piping should go vertical and never slant downwards. Termination of the vent must
conform to standards.
Direct venting is not available for installations within European Community Countries.
Direct venting is not an option for Il Forno ovens.
Il Forno ovens, singly or stacked, may be vented with an optional Eye Brow Hood. Eye Brow hoods
are shipped separately for installation before first use. A separately sized and designed exhaust fan system must also be installed.

FLAME AND BURNER ADJUSTMENTS
GAS PRESSURE ADJUSTMENTS
Baker’s Pride ovens are equipped with fixed sized orifices. Adjustments can not be made to the orifice.
Gas flow and pressure is to be checked at installation.
A pressure tap is supplied with each oven. It is located
in the control compartment along the gas supply piping.
On older models this tap will be along the manifold
pipe or fittings. On newer models the pressure tap will
be located between the gas valve and thermostat.
Gas supply pressure must match the oven’s rating plate.
This value must be checked with the oven and all other
appliances on the same gas supply line running at their
highest burner setting.

NEWER
LOCATION
TRADITIONAL
LOCATION
Connect a manometer to the pressure tap and check the
gas pressure while the burners are running at their highest setting. Ovens equipped with a 7000 combination
valve have an adjustment screw on the front of the valve. Ovens equipped with a pilot safety valve will
have a traditional regulator in the gas line before the valve.
This adjustment is originally made at the factory prior to shipment. However, it must be re-checked
and/or adjusted at installation to match your gas supply. This adjustment is not covered by warranty.
PILOT LIGHTING AND ADJUSTMENTS
Most ovens have a combination valve that supplies gas to the pilot burner. Some ovens have a pilot
safety valve. The basic method is the same for each.
The 7000 combination valve has a dial that controls the gas flow. Turn it to “PILOT”. The pilot safety
valve has a RED button.
Turn the gas supply to the oven ON.
Slightly depress and turn the combination gas cock knob to the PILOT position.
Depress the dial or the red button and hold. It may take several minutes to bleed air from the tubing
supplying gas to the pilot burner.
Apply a flame to the pilot burner to light. Continue to hold the dial/button depressed for at least 30
seconds for the flame to be sensed by the valve.
After letting go of the dial/button if the pilot flame goes out repeat the
above steps.
Once the flame is lit and burning normally for several minutes to insure
all air is bled from the supply tube the flame may need to be adjusted.
On pilot safety valves there is an adjustment screw above the red button.
On combination valves there is an adjustment screw at the top left corner
of the valve body. Remove the pilot adjustment cap.
Using a small flat blade screwdriver turn the screw counter-clockwise to
reduce the size of the flame. Turn the screw clockwise to increase the
size of the flame. The flame should be approximately 3/8 in to 1/2 in
high and wrap around the flame sensor bulb.

FLAME AND AIR MIXTURE ADJUSTMENTS
Light the burners and turn the thermostat dial to the desired temperature setting. Allow the flame to
burn for a few minutes to settle.
Observe the burner flame. The flame should be sharply formed cone shapes that are blue in color . If
your fuel source is propane there may be yellow tips that flicker briefly.
If the flame is not formed, is lazy, and has a lot of yellow color, not enough air is mixing with the gas.
If the flame “roars” and you can see the base of the flame separating from the burner pipe– lifting,
there is too much air mixing with the gas. For either condition the air/fuel mixture must be adjusted.
A. Loosen the locking disk.
LOCKING DISC
B. Turn the larger adjusting disk towards the gas/
air port of the inspirator to reduce the opening to
ADJUSTING DISC
reduce the air. The flame will turn lazy and yellow in color.
C. Gradually turn the adjusting disk away from the
gas/air port to increase the opening and thus increase the air. The flame shape will become
more cone shaped and the yellow color will disappear.
D. Observe the flame for a minute to insure the setting does not have be adjusted more. Tighten
the locking ring against the adjustment disk.
This adjustment is originally made at the factory prior to shipment. However, it must be re-checked
and/or adjusted at installation to match your gas supply. It may also need to be periodically adjusted
during the life of your oven, especially if the fuel source is propane. This adjustment is not covered by
warranty.

Your oven is equipped with a throttle back thermostat that continually maintains a small flame to help
reduce temperature swings as the burners cycle on and off. When the oven reaches set temperature the
thermostat main valve closes and only gas from the by-pass valve flows to the burners.
BYPASS ADJUST
Turn the temperature dial to 300 º.
After the oven temperature rises and remains constant turn the dial back down
to the lowest setting.
This closes the main valve.
Remove the knob by pulling straight from the thermostat body.
Refer to the figure showing a thermostat with knob removed.
There are two adjustment screws on the left side of the thermostat body. The
upper screw has a “B” marking along side. Using a small flat blade screwdriver turn the screw to adjust the by-pass flame.
Turn the screw counter-clockwise to increase the flame height. Turn the screw
clockwise to reduce the flame height.
When properly set there should be a minimal height flame that maintains itself
along the burners.
Replace the dial. Turn the temperature up and down several times to insure the
by-pass flame maintains at a minimal setting.
This adjustment is made at the factory prior to shipment. However, it must be re-checked and/or adjusted at installation. This adjustment is not covered by warranty.
AUTOMATIC TIMER
When ordered the automatic oven start timer will turn the main burner on at the set time of your choosing.
The thermostat jumper between the TH-TP and TH contacts on the 7000 combination gas valve are replaced by wire leads to the switch contacts of the timer. The red and white leads from the Thermopile
must be connected. The main burner will not turn on unless the pilot is lit.
NO VOLTAGE IS TO BE CONNECTED TO THESE CONTACTS. This connection is an extension of the jumper which tells the valve open the main gas valve. At the appointed time the clock
closes the switch terminals and completes the circuit. The valve interprets this as a call for heat and
opens the main gas valve.
The main burner may be lit manually by opening the switch box and turning the timer switch to the
“ON” position.

TERMINAL
BLOCK
The Il Forno booster burner is located in the center rear of the oven cavity visible through the front
opening as an added visual effect. It also provides 20 KBTU additional heat to the oven.
Controls for this feature are in the left side compartment behind the typical gas control stack. The
booster burner is plumbed and controlled separately from the main burner. There is an ON-OFF switch
just inside the control compartment door. There is an ON-OFF switch on the gas valve.
When turned on the ignition module energizes the hot surface ignitor. When the hot surface ignitor
reaches current a signal opens the gas valve for the burner. The flame sensor completes the circuit
when it signals the ignition module it is sensing flame. This burner has its own inspirator and it typically adjusted to provide a YELLOW flame to simulate wood burning at the back of the cavity.

GAS CONVERSION
WARNING
Conversion kits shall be installed by a qualified service agency in accordance with the
manufacturer's instructions and all applicable
codes and requirements of the authority having jurisdiction. If the information in these
instructions is not followed exactly, a fire, an
explosion or production of carbon monoxide
may result causing property damage, personal
injury or loss of life. The qualified service
agency is responsible for the proper installation of this kit. The installation is not proper
and complete until the operation of the converted appliance is checked as specified in the
manufacturer’s instructions.
There are times it is required to do a field conversion from one gas type to another.
Consult with your Technical Service Representative to order the correct parts for the oven model you
will be converting.

Shut off the gas to the oven.
Remove the two screws that hold the regulator in place on the combination valve. Remove the gasket. Install a new gasket and the new regulator. Insure the regulator gasket is in place with two
circular cut-outs over small posts in the valve body casting. Evenly tighten the two screws holding
the regulator in place. The conversion kit includes a label to be placed on the side of the valve
body to inform others that the conversion has taken place.
Remove the orifices from the inspirators. Depending on the oven model there will be one, two or
three that need to be changed.
Change the orifice in the pilot.
Refer to other sections of this manual. Test for gas leaks.
Follow normal start-up procedures for lighting and adjusting the pilot and insuring the gas-air mixture to the burners is correct.

TROUBLE SHOOTING
TEMPERATURE CALIBRATION
Thermostats are calibrated at the manufacturer and field adjustments are seldom necessary. They
should not be made unless actual cooking experience indicates the control is not maintaining set temperature. Breaking the seal on the calibration plate locking screws may void the manufacturer’s warranty for the thermostat.
Use a digital thermometer.
Place a thermocouple along the capillary bulb in the oven cavity.
Close the door.
Light the main burner. Adjust temperature setting to 400ºF.
Allow oven to heat until burner flame drops to by-pass.
Check temperature reading at thermometer. If not within 25º of set
point adjust dial setting.
To adjust:
Pull knob straight off. Do NOT turn stem while removing knob.
Grasp calibration plate and hold in place while loosening two calibration lock screws. Use a #1 Phillips screwdriver.
The calibration plate has markings and the name “ROBERT
SHAW” stamped in it. There are approximately 50º between each
letter.
Turn calibration plate counter-clockwise to lower set point.
Turn calibration plate clockwise to increase set point.
Tighten locking screws and replace dial.

TEST THERMOPILE AND VALVE
Use these test procedures to trouble shoot the thermopile and combination gas valve. Prior to performing any tests clean and tighten all wire connections at the combination valve.
Clean the pilot orifice and insure the Thermopile is not coated with soot from a high pilot flame.
Use a digital volt meter with a scale capable
of reading millivolts.
System Test - pilot lights, main burner does
not.
Connect volt meter leads between terminal 2
and terminal 3. Turn gas cock dial to “ON”.
If meter reading is greater than 100 mV replace valve. If meter reading is less than 100 1
mV run additional tests.
Thermopile Output Test - pilot won’t stay lit 2
or main burner won’t light.
Connect volt meter leads between terminal 1
and terminal 2. Remove jumper from termi- 3
nal 3. Gas cock dial in “PILOT” position. If
meter reading is less than 325 mV replace
