LEVELING AND SHIMMING THE OVEN.
The installed oven must be level. Use metal shims to level the oven if necessary. Because the weight of the oven is carried by the full perimeter of the oven stand, make certain there no gaps larger than approximately 13mm (1/2″) where the oven stand is unsupported by shims. Seal any small gaps between the oven and the floor with silicone. Failure to solidly support the full perimeter of the oven stand can result in costly damage to the oven and will void the warranty. The floor design and construction must be adequate to handle the weight of the oven.
Please see woodstone-corp.com for floor loading information.

MOVING THE OVEN.

The oven should only be moved using a Pallet Jack on a smooth, LEVEL FLOOR.Use a Forklift or other suitable means if the oven must be moved over an inclined surface.

Never use a Hand Truck to move the oven.

Make sure the Pallet Jack wheels do not contact the underside of the fork pocket when lifting to avoid damaging the stand.

USING A CRANE.
The oven arrives with Pickeyes attached. When craning a Wood Stone oven, use a Spreader Bar with a two-legged sling rigged on each end. The spreader bar should be of a sufficient length to keep the sling from contacting the oven, and oriented as shown in fig 1.

INSTALLATION CLEARANCES

WARNING: Do not pack required air spaces (clearance) with insulation or other material.

WARNING: Installation and servicing of this product could expose you to glass wool/ceramic fibers as well as calcium silicate dust. ALWAYS WEAR RESPIRATORY AND EYE PROTECTION WHEN INSTALLING OR SERVICING THIS APPLIANCE. Please read this entire manual before you install the oven. Failure to follow instructions may result in property damage, bodily injury, or even death. Contact your local building or fire officials about restrictions and installation inspection in your area.

CLEARANCES

1. The Wood Stone Phoenix oven must have a minimum 25 mm (1″) clearance to combustibles from all sides, and 152 mm (6″) clearance to combustibles from the top. If building materials will contact the oven, they must be completely non-combustible.
   Please note that standard Drywall (or Sheetrock) is considered combustible. When non-combustible building materials contact the body of the oven, the respective clearances are transferred to those non-combustibles.

2. Any facade 152 mm (6″) to either side of the oven doorway or above, must be constructed of non-combustible building materials.

3. For gas-only models, this oven is suitable for installation on combustible floors.
   NOTICE: For stucco-ready appliances (model numbers ending in “-S”), the same clearances as described above apply. Noncombustible stucco mix must be used and applied to a minimum thickness of 25mm (1″).

Lined area 152 mm (6″) to either side of the doorway and above) represents space where facade materials must be non-combustible.

The hatched area must be left accessible and unobstructed after installation for air intake and routine service of the oven burner.

VENTING

All of the combustion products and cooking vapors from the Wood Stone Phoenix oven pass through the 10-inch diameter flue collar located on top of the oven at the front. The oven can be connected to a power-ventilated, grease-rated chimney, or placed under a Listed Type 1 exhaust hood. Installation of the exhaust hood should be in accordance with all relevant local and national codes.

THIS OVEN IS NOT INTENDED TO BURN SOLID FUEL. DO NOT BURN ANY TYPE OF SOLID FUEL IN THIS OVEN.
The following are the manufacturer’s recommendations for venting Wood Stone Phoenix model ovens. It is never appropriate to use a “B vent” in any part of an exhaust system connected to a Wood Stone oven. All duct material must be manufactured to the specifications of a grease duct. The venting system should be cleaned and inspected at least every 3 months.

THERE ARE TWO VENTING OPTIONS:

1. A grease rated duct connected directly to the oven flue collar and provided with a power ventilator suitable for restaurant appliance exhaust and rated for operation at a minimum of 149 °C (300 °F), 232 °C (450 °F) for units burning solid fuel.
   Use a stack or curb-mounted fan. Wood Stone does not recommend the use of an in-line fan. Static pressure of 0.25 bar (-0.1 inches) a water column is necessary at the oven flue collar to ensure proper flue temperatures at the fan. The airflow required to attain this static pressure will depend on the configuration of your particular installation but will be approximately 400 CFM. The exhaust fan must be turned on any time the oven is running. See instructions for optional interlocking of the oven to the fan at the end of this manual

2. Wood Stone offers eyebrow-type hoods designed specifically for Wood Stone ovens by Gaylord Industries.

FLUE ADAPTER INSTALLATION

BISTRO LINE OVENS: FLUE ADAPTER INSTALLATION
The flue adapter unit is designed to facilitate connection to a round duct. Use the provided stainless steel screws and sealant provided to attach the flue adapter (10″ I.D.) to the exhaust outlet on the oven.
Note: If using a Selkirk or other modular-type duct, attach according to the manufacturer’s instructions. Otherwise, the duct must be attached with a full perimeter weld. A grease-rated duct is required throughout the system. If the oven is going to be enclosed, the flue adapter and exhaust outlet must be wrapped with an insulating material approved for use with a grease duct.

The flue adapter is for direct connection to a duct system ONLY.
DO NOT install if the oven is installed under an exhaust hood.

LIFTING THE OVEN

MOVING A DISASSEMBLED BISTRO OVEN THROUGH A NARROW DOOR OR PASSAGEWAY USING THE OPTIONAL LIFTING SYSTEM

    Knockouts are provided on the rear of the oven stand for the incoming gas and electrical supplies. If necessary, holes may be drilled in a side panel for the incoming gas and electrical. Gas and electrical supplies should be routed in such a way that they do not interfere with the removal of the oven burner or block access to space under the oven for service. The area beneath the burner needs to be kept clear of conduit and piping to allow for the removal of the burner for service. A 19mm (3/4″) full-flow gas shut-off valve should be installed on the gas supply near the oven in such a way that it is readily accessible.
    THE REAR PANEL OF THE OVEN MUST BE INSTALLED FOR PROPER FUNCTIONING.
    ELECTRICAL CONNECTION
    This appliance must be electrically grounded in accordance with local code, or in the absence of local code the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2, as applicable.
    An Electrical Diagram is provided inside the bottom cover of the Control Box, and at the end of this manual.

14. 15. Checking the burner manifold pressure. The burner manifold pressure has been set at the factory, however, it should be checked by the installer. The pressure should be checked at the outlet tap on the Honeywell gas valve, located on the back of the control box. Once the manometer is connected, turn the oven on and use the knob on the oven to adjust the flame to its maximum height. Then check the manifold pressure.
        This oven requires no modifications or adjustments for use at high altitudes.
        The installation must conform with local codes, or in the absence e of local codes with the National Fuel Gas Code, ANSI 223.1, or the Natural Gas Installation Code, CAN/CGA-B149.1, as applicable.
        SV-2 and SV-3 are the gas control valves that operate the Radiant Burners. The manifold pressures are checked at the outlet port on the individual gas valves.
        The burner manifold pressures have been adjusted and tested at the factory. A variety of factors can influence these pressures, so be sure to test the individual burner manifold pressures and adjust the valves as necessary to achieve the required pressures.
        NOTE : The gas valves are shipped in the ON position.

Maximum inlet gas pressure must not exceed 34 bar (14″ W.C. or 1/2 psi)

GAS INLET PRESSURE

For ovens running on natural gas, an inlet pressure of 17.5-25bar (7 to 10″ W.C.) is recommended to ensure optimum oven performance. Incoming gas pressure below this range will affect oven performance, the lower the pressure the greater the negative impact. If the gas supply pressure is greater than 34bar (14″ W.C. or 1/2 psi), an external regulator, supplied by others, is REQUIRED to lower the gas pressure to the acceptable range. Issues caused by low or high gas pressure are installation issues, and will not be covered under the Warranty.

For ovens running on LP, the recommended inlet pressure to ensure optimum oven performance is 25-30bar (10 to 12″ W.C.) Incoming gas pressure below this range will affect oven performance, the lower the pressure the greater the negative

impact. If the gas supply pressure is greater than 34bar (14″ W.C. or 1/2 psi), an external regulator, supplied by others, is REQUIRED to lower the gas pressure to the acceptable range. Issues caused by low or high gas pressure are installation issues, and will not be covered under the Warranty.

For all installations, follow best practices for proper gas line pipe sizing for the line serving the oven. To ensure proper

operation, all gas piping and fittings leading up to the oven should have an inside diameter equal to or greater than that of the oven gas connection. Also, make sure that a readily accessible shut-off valve (supplied by others) is installed near the oven, and in accordance with all applicable codes. Shut- off valves must be of the full-flow type, and not introduce any restriction into the gas line.

The connection to the oven should be hard-piped whenever feasible. If this is not possible, use a properly sized flexible

connector approved for this application. When using a flexible connector make sure that its design does not present any reduction in pipe diameter or other restriction. Oven issues caused by improper pipe sizing, improper shut-off valves,

restrictive connectors, or any other deficiency in the gas supply design or installation will not be covered under the oven warranty.

15. Install the rear panel, front panel, and toe kick using the 1/4-20 screws provided. The front panel on the oven must not be covered, so as to allow access for service to the oven components. The oven should be bolted to the floor using the holes provided at the base of the stand.

NOTE: REAR PANEL MUST BE INSTALLED FOR THE PROPER FUNCTIONING OF THE OVEN

INSTALLATION OF OPTIONAL STORAGE BOX

1.  Install Toe Kick (w/ perforations) using (3) provided 1/4-20 screws (a).
2. Slide Storage Box into the front of the oven, flush to side panel flanges, and Toe Kick. Fasten using (4) provided 1/4-20 screws (b).
3. Tuck Storage Box Connector under control panel and over top of Storage Box. Fasten using (2) provided 1/4-20 screws (c).

CONTROLLER FUNCTIONS

INITIAL OVEN START-UP

IMPORTANT: If at any time you feel that either or both of the burners are not operating properly, turn the oven off and call for service. Before servicing, disconnect the electrical supply at the breaker and turn off the gas supply at the appliance’s individual gas shutoff valve. In the event of a power failure, no attempt should be made to operate the oven.

Your oven was cured at the factory. However, in the course of shipment, storage on site, etc. the ceramic materials will have absorbed moisture. It is critical that the Initial Oven Start-up procedure below be followed to ensure that this moisture is driven from the ceramic in a controlled fashion. This will minimize cracking and prevent damage to the oven that could otherwise occur by bringing the oven to temperature rapidly the first time it is used.

Occasionally, through the course of the initial start-up, as the oven heats up it is possible that you will see some water dripping from the sides of the oven as moisture is driven out of the ceramic. This is not a defect in the oven, and once the oven has been fully saturated with heat, the moisture will be driven fully from the oven.

This Initial Oven Start-up procedure needs only be followed the first time the oven is fired and/or if the oven has not been used for an extended period of time.

FIRST DAY

1. Make sure the exhaust fan is properly wired and interlocked to the appliance.
2. Make sure the main gas supply is ON (valve parallel with gas line).
3. Push the VO button on the controller. The exhaust fan should come on as It may take a while for the gas to purge all the air from the gas lines. (Verify both burner’s light. If only one is lite, check that the Burner Disable switch on the front panel is in the ON position.
4. Once the burner(s) ignite(s), make sure the flame is at its lowest setting and allow the appliance to operate at this setting for about 1 hour.
5. After 1 hour, using the Flame Height Control Knob, raise the radiant flame to “2” on the Flame Height Index Scale.
6. After 4 hours a raise to “3” on the Flame Height Index Scale and allow the appliance to run until it reaches a temperature of 260 °C (500 °F). This will take approximately 3-4 hours.

NOTE: Small “crazing” cracks will occur with normal heating and cooling. They will not affect the performance or durability of the oven. If cracks of 3 mm (1/8″) wide or more develop, contact Wood Stone for evaluation.

FLAME HEIGHT INDICATOR
Comprised of two parts

IMPORTANT NOTE ON DUAL BURNER MODELS

The (2) flame height control knobs are linked together for ease of use. Turning either knob will raise or lower both flames. If you wish to unlink the knobs for individual control of each burner, please contact the factory for instructions.

DAILY OVEN OPERATION

The oven floor temperature is displayed on the controller readout.

END OF THE DAY

Push the I/O button on the controller. All gas will go OFF, even the pilots. When the oven is turned OFF, use the Night Heat Retention Door to help retain heat in the oven. The night door is placed into the open doorway. NOTE: This option is for heat retention only, and should only be used when the oven is turned OFF.

BEGINNING OF THE DAY

Make sure the night door is removed. Push the I/O button and tum the radiant flame to its highest setting using the Flame Height Control Knob. The oven should reach the desired cooking temperature typically within 2 hours. Use the Flame Height Control Knob to control the amount of heat in the oven.

See woodstone-corp.com for detailed information on cooking in your Wood Stone oven.

OVEN INTERIOR

Wood Stone recommends the use of long-handled brushes for sweeping up surface debris that will accumulate on the floor of the oven during use. Use a natural fiber brush—always brushing away from the radiant burner well. For deeper cleaning, use a brass bristled brush. The oven floor can be then cleaned with a damp rag wrapped around the brass bristled brush head. (Wood Stone offers an assortment of oven brushes available through your dealer. Specification sheets may be viewed on the Wood Stone website under Tools & Accessories.)

DO NOT POUR OR SPRAY LIQUIDS ONTO THE OVEN DECK OR INTO THE OVEN INTERIOR AS
THIS CAN DAMAGE THE CERAMIC AND WILL VOID THE WARRANTY.

There is a stainless steel burner guard to prevent food from falling on and thereby obstructing the gas orifices of the radiant flame. If food gets into the radiant flame well and the flame is visibly obstructed, tum the oven off immediately, and call for service.

DO NOT USE THE RADIANT BURNER WELL AS A DUMP FOR DEBRIS OR TRASH INCINERATION;
MAKE EVERY ATTEMPT TO KEEP DEBRIS FROM DROPPING INTO THE WELL.

OVEN EXTERIOR

All painted and stainless steel surfaces should be cleaned as necessary using a mild detergent, hot water, and a soft cloth or sponge. Stubborn residues may be removed using a nonmetallic scouring pad. When scouring stainless steel surfaces, scrub with the grain of the metal to prevent scratching.

GAS-FIRED OVEN THERMAL CLEANING

If a Wood Stone gas-fired oven is operated at low temperatures below 274 °C (525 °F), you may notice a buildup on the oven floor. If you operate the oven below 232 °C (450 °F), you may also notice some buildup on the interior walls and/or ceiling of the oven. To remove any buildup that has accumulated inside of the oven, simply tum the radiant flame to its highest setting. Monitor the hearth floor temperature displayed on the controller. When the floor reaches 343 °C (650 °F), lower the flame slightly so as

to maintain the oven floor temperature near 343 °C (650 °F) for about an hour. Heavy accumulations may require more time. Heavy accumulations on the floor may require some additional scraping with a utility peel or a floor scraping tool. Once the oven appears clean, allow the oven to return to normal operating temperatures and continue normal operation.

Never use any type of chemical cleaner on the oven ceramic. This will damage the oven and void the warranty.

1. Incoming power to oven turned off. Check the circuit breaker for the circuit supplying the oven. Check that any wall switches external to the oven that control oven power is turned on. Check that any interlocks external to the oven are turned
2. If the controller still does not turn on, please contact Wood Stone for assistance.

1. Check gas is turned on to the oven, and the gas shut-off valve is turned all the way on.
2. Debris in the burner. The burner may require cleaning. Contact your distributor for assistance.
3. Damaged igniter or gas valve. Contact your dealer for assistance.
   If the oven is being started for the first time:
   – Has all air been bled from the gas line?
   – Is the switch on the SV-2 and SV-3 valve in the ON position?

NOTE: Valves are located on the back of the control box, beneath the oven.

Flame cuts out|

1. Debris in the burner.
2. The oven is being run with the night door in place. Night Heat Retention Door must be removed whenever the oven is turned on.
3. Wind blowing into the oven, or other venting issues.

200-240 VAC

INTERLOCK OF OVEN CONTROL TO AN EXHAUST FAN
This connection is intended to interrupt power to the oven until the fan is turned on.

S1 is a double pole, single throw switch (provided by others) that interrupts incoming power to both the oven and the fan. The intent is to prevent the operation of the oven’s gas burner in the event the fan is shut off.
Any interruption of the power to the oven will cause the oven (including all burners and pilots) to shut off, and it will be necessary to restart the oven by pressing the start switch once power is restored.
For additional interlock options, see the Wood Stone Interlock Options supplement in the Manuals section on the website, woodstone-corp.com, or contact your distributor for additional information.
