The oven can be moved over a flat surface with a pallet jack using the LOWER forklift pockets. If the oven is to be
installed against a wall, you may need to leave access to the back of the oven to complete the utility connections.
PLACING THE OVEN
The oven must be installed on a flat level surface. The weight of the oven is carried by the full perimeter of the oven
stand. If it is necessary to shim the oven for leveling purposes, it is critical that the shim material be metal, and that the
shims are installed in such a way that the full perimeter of the stand is solidly supported. Any gaps created by shimming
between the oven and the floor must be sealed for proper ventilation. 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/installation_footprints.htm for floor loading information.
FORKLIFT REQUIREMENTS
The oven is very top-heavy. IF THE OVEN TIPS IT CAN CAUSE SEVERE INJURY OR DEATH! NEVER ATTEMPT TO USE A
HAND TRUCK TO MOVE THE OVEN. The oven should only be moved using a pallet jack on a LEVEL FLOOR. If the oven
must be moved over an inclined surface, a forklift or other suitable means should be employed. If the installer does not
have the equipment or experience required to move the oven safely, we recommend you secure the services of a
qualified rigging company.
Make sure the pallet jack
wheels do not contact
the underside of the fork
pocket when lifting to avoid
damaging the stand.
Never attempt to use a hand
truck to move the oven.
The oven should only be moved
using a pallet jack on a LEVEL
FLOOR. If the oven must be moved
over an inclined surface, a forklift
or other suitable means should be
employed.

Flue collar
WOOD STONE OVENS SHOULD BE VENTED IN
ACCORDANCE WITH NFPA 96 AND/OR ALL PERTINENT
NATIONAL, REGIONAL AND LOCAL CODES CONCERNING
SUCH APPLIANCES. CHECK VENTING PLANS WITH
THE AUTHORITY HAVING JURISDICTION BEFORE
PROCEEDING WITH INSTALLATION.
All of the combustion products and cooking vapors from all Dual Burner Bistros 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 the Standard
for Ventilation Control and Fire Protection of Commercial Cooking Operations, NFPA 96.
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 Dual Burner Bistro model ovens. It is
never appropriate to use “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 Listed building heating appliance chimney, also listed as a grease duct connected directly to the oven flue collar
and provided with a power ventilator listed for restaurant appliance exhaust and rated for operation at a minimum
of 300 °F. Use a stack or curb mounted fan. Wood Stone does not recommend the use of an in-line fan. A field built
grease duct installed and constructed according to the requirements spelled out in NFPA 96, or the International
Mechanical Code.
A static pressure of -0.1 inches 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 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. A Listed Type 1 exhaust hood or one that is constructed and installed in accordance with all relevant local and national
Codes. Wood Stone offers eyebrow-type hoods designed specifically for Wood Stone ovens. See specification sheet
on ventilators for Wood Stone ovens.

UTILITY CONNECTIONS
Bistro Dual Burner Oven
Installation and Operation Manual
ASSEMBLY-CONNECTIONS
Connect the incoming gas
supply to the 3/4-inch FNPT
gas inlet.
For non-plug models, make the electrical
connection to the terminals in junction box.
Correct voltage is specified on the junction
box and the equipment data plate.

14
The installation must conform with local codes, or in the absence of local codes with the National Fuel Gas
Code, ANSI 223.1 or Natural Gas Installation Code, CAN/CGA-B149.1, as applicable.
1. The appliance and its individual shutoff valve (supplied by others) must be disconnected from the gas
supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi (3.45
kPa).
2. The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff
valve (supplied by others) during any pressure testing of the gas supply system at test pressures equal to
or less than 1/2 psi (3.45 kPa).
The incoming gas supply pressure must not exceed 1/2 psi (14 inches W.C.). If the incoming gas pressure
exceeds 1/2 psi, an external gas regulator must be installed in the supply line. If the supply pressure is less
than 1/2 psi, no external regulator is required.
The installer should bleed any air out of the gas line supplying the oven. All gas connections and fittings on the oven
should be leak checked with an approved soap solution.
CHECKING THE BURNER MANIFOLD PRESSURES
The burner manifold pressures have been set at the factory. However, they should be checked by the installer. The
pressures should be checked at the outlet tap on each 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.
All Models
Natural Gas (NG): 4.5" W.C.
Propane (LG): 10" W.C.
This information can also be found on the data plate located beneath the oven.
FRONT AND REAR PANEL INSTALLATION
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.

INITIAL OVEN START-UP FOR DUAL BURNER BISTRO MODELS
FIRST DAY
1. Make sure main gas supply is on (valve parallel with gas line).
2. Push I/O button on controller. It may take a while for the gas to purge all the air from the gas lines. (Verify both
burners light. If only one is lite, check that the Burner Disable switch on the front panel is in the ON position.)
3. Once the burners ignite, make sure the flames are at their lowest setting and allow the oven to operate at this setting
for about 8 hours, or until the temperature reaches 450 °F.
SECOND DAY
1. Turn the radiant flames all the way up until the desired cooking temperature is achieved.
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.
NIGHT HEAT RETENTION DOOR
The night door should be removed whenever the oven is turned ON.
Night Heat Retention Door
NOTE: Never operate this appliance with the
(optional) stainless steel Night Heat Retention
Door in place. This option is for heat retention
only, and should only be used when the
appliance is turned off.

Oven should reach the desired cooking temperature 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.
CLEANING THE OVEN
1. As needed (twice per hour), use the floor brush to sweep stray food debris to the doorway, where it can be easily
removed with a dough cutter or spatula.
2. As needed, swab the deck using a damp (not wet) rag wrapped around the floor brush. Take care not to brush debris
into the radiant flame burners.
DO NOT POUR OR SPRAY LIQUIDS ONTO THE OVEN DECK OR INTO THE OVEN INTERIOR

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 wells. 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.)
TAKE CARE NOT TO BRUSH DEBRIS INTO THE RADIANT FLAME BURNERS.
OVEN EXTERIOR (DOORWAY AND MANTLE)
All exterior stainless steel surfaces should be cleaned as necessary using an approved mild detergent, hot water and a
soft cloth or sponge. Stubborn residues may be removed using a non-metallic scouring pad. When scouring stainless
steel surfaces, scrub with the grain of the metal to prevent scratching.
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.
IMPORTANT: DO NOT USE EXCESSIVE AMOUNTS OF LIQUID WHEN WIPING
ON OR AROUND THE OVEN CONTROL BOX.
THERMAL CLEANING
If a Wood Stone gas-fired oven is operated at low temperatures (below 525 °F), you may notice a buildup on the oven
floor. Note that this floor buildup may be perceived as the floor flaking away. If you operate the oven below 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 turn the radiant flame to its highest setting. Monitor the floor temperature displayed on the
controller. When the floor reaches 650 °F, lower the flame slightly so as to maintain the oven floor temperature near
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.
