RFG Oven Installation and Operation Manual
UNLOADING AND MOVING
LIFTING THE OVEN
1. USING A CRANE
The oven arrives with four lifting eyes attached.
When craning aWood 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.
NOTE: Once lifting eyes are no longer needed,
remove the lifting eyes one at a time AND BE
SURE TO REPLACE THE BOLTS THAT ATTACH
THE OVEN TO THE STAND.
2. USING A FORKLIFT
USING A PALLET JACK TO MOVE A WOOD STONE OVEN
Once the oven has been removed from the delivery vehicle, it
can easily be moved on flat surfaces using a pallet jack. To lift
the oven with a pallet jack, remove the front and rear angle
iron stabilizers from the base of the oven stand and place a
stout 4x4 post through the fork pocket as shown. THE OVEN
IS VERY TOP-HEAVY, MOVING THE OVEN UP OR DOWN
A RAMP ON A PALLET JACK IS NOT SAFE!
Contact Wood Stone if the oven must be turned on its side for specific instructions. Moving a Wood
Stone oven can present interesting challenges to even the most experienced riggers.
Take your time, use your head, secure the proper equipment and make safety your first priority. Please
don’t hesitate to call the factory for technical support (1-800-988-8103).
DO NOTTURNTHE OVEN ON ITS SIDE!

DELIVERY NOTE:
The customer will receive an Oven Shipping Notification when the oven leaves the Wood Stone factory.
This will include a PRO# and a trucking company contact number. Wood Stone recommends that you
confirm the delivery date/time with the trucking company before committing to heavy equipment and/
or labor. Our goal is a smooth and safe delivery. Thank you.
LIFTING EYES
Be sure to use a forklift rated to lift more than the
oven weighs as shown below. Fork length must be
at least 6 feet, if not, fork extensions should be used.
The oven stand is equipped with fork pockets just
above the angle iron base. The oven is very top
heavy so spread the forks as far apart as possible.

RFG Oven Installation and Operation Manual
IF THIS OVEN IS NOT PROPERLY INSTALLED A FIRE MAY RESULT. TO
REDUCE THE RISK OF FIRE, FOLLOW THESE INSTALLATION
INSTRUCTIONS. A MAJOR CAUSE OF OVEN RELATED FIRES IS
FAILURE TO MAINTAIN REQUIRED CLEARANCES (AIR SPACES) TO
COMBUSTIBLE MATERIALS. IT IS OF UTMOST IMPORTANCE THAT THIS
OVEN BE INSTALLED ONLY IN ACCORDANCE WITH THESE
INSTRUCTIONS.
WARNING: Installation and servicing of this product could expose you
to glasswool/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
a. The Wood Stone RFG oven should have a minimum 1'’
clearance to combustibles from all sides, and 14" clearance to
combustibles from the top (See Figures 1a. and 1b on page 6). If
building a facade that will contact the oven, use completely non-
combustible materials*. Please note that standard dry-wall (or sheet
rock) is considered a combustible.
b. Any facade above and/or 6 inches to either side of the oven
doorway, must be constructed of non-combustible building materials.
NOTICE: FOR STUCCO COVERED OVENS (MODEL NUMBERS
ENDING IN “S”), 36” CLEARANCE TO COMBUSTIBLE BUILDING
MATERIALS IS REQUIRED
* When non-combustible building materials contact the body of the oven, the
clearances to combustibles are transferred to those non-combustibles.
INSTALLATION CLEARANCES
c. Install this oven only on non-combustible floors. The non-
combustible floor surface should extend 36 inches out in front of the
oven, and extend 30 inches to either side of the oven doorway.

RFG Oven Installation and Operation Manual
GAS
The Wood Stone Gas ovens are equipped with a 3/4" NPT gas connection
located at the rear left of the oven. Have a licensed gas installer provide
the hook-up and test all fittings and pipe connections for leaks. Use
approved gas leak detectors (soap solutions or equivalent) over and around
the fittings and pipe connections. DO NOT USE FLAME TO TEST FOR
LEAKS!
SV-2 is the gas control valve that operates the interior radiant burner. SV-2 is
located under the oven to the rear left.
The manifold pressure test port for the radiant burner is a 1/8" NPT
plugged tapping located at the base of the T-junction between the SV-2
and the radiant/interior burner.
The burner manifold pressure has been adjusted and tested at the factory. A
variety of factors can influence this pressure, so be sure to test the burner
manifold pressure and adjust the valve as necessary to achieve the specified
pressure. Note: The gas valve is shipped in the 'on' position.
Factory specified individual burner manifold pressures for RFG
models equipped to burn Natural Gas.

The following are the manufacturer’s recommendations for venting theWood Stone MS (Mountain
Series) RFG ovens. It is never appropriate to use“B vent”in any part of an exhaust system connected
to aWood Stone oven. All ducting material must be manufactured to the specifications of a grease
duct. Submit your venting plans to your local authorities before proceeding with your installation, as
OVEN VENTING
there may be additional requirements in your area.
There are three options:
1. Direct connection.
A listed building heating appliance chimney,also listed as a grease duct as described in NFPA 96,
connected directly to the oven flue collar and provided with a power ventilator listed for restaurant
appliance exhaust.The power ventilator should be rated for a minimum of 300 degrees F.Wood
Stone does not recommend the use of an in-line fan. A single wall chimney/duct connector may be
used to connect the oven to a listed building heating appliance chimney also listed as a grease
duct.The chimney /duct connector should be a minimum .044 inch stainless steel or 16 ga. mild
steel (0.055 inch) and must maintain a minimum of 18 inches to combustibles.
A static pressure of -0.1 inches water column is necessary at the oven flue collar to ensure that flue
gas temperatures do not exceed 300 degrees Fahrenheit at the fan inlet.The CFM required to attain this
static pressure will depend on the configuration of your particular installation but will probably be between
500 and 700 CFM. Wood Stone provides a port in the flue collar of the oven for insertion of a magnehelic
gauge so the installer can monitor the draft to ensure proper operation of the venting system. NOTE:
Double door ovens (Models ending in DD), have two flue collars, both must be connected and a
static pressure of negative 0.1 inches must be maintained at each collar.
When using a direct connection as described above, the duct must be attached to the oven
flue collar with a full perimeter weld.
Install venting system in accordance with the duct manufacturer's instructions
and in accordance with all local codes. All field built components should be
built to the applicable codes and standards and are subject to the approval of
the authority having jurisdiction.
2. A ListedType 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.
