LIFTING THE APPLIANCE
1. USING A CRANE
The appliance arrives with four lifting eyes at-
tached.When craning, 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 sides of the
appliance. NOTE: Once lifting eyes are no longer
needed, remove the lifting eyes one at a time AND
BE SURE TO REPLACE THE BOLTS THAT AT-
TACH THE MAIN BODY TO THE STAND.
2. USING A FORKLIFT
USING A PALLET JACK TO MOVE THE APPLIANCE
Once the appliance has been removed from the delivery ve-
hicle, it can easily be moved on flat surfaces using a pallet
jack. To lift with a pallet jack, remove the front and rear angle
iron stabilizers from the base of the stand and place a stout
4x4 post through the fork pocket as shown. THE APPLIANCE
IS VERY TOP-HEAVY, MOVING THE APPLIANCE UP OR
DOWN A RAMP ON A PALLET JACK IS NOT SAFE!
Contact Wood Stone if the appliance 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 (1-800-578-6836).
DO NOT TURN THE APPLIANCE ON ITS SIDE!

UNLOADING AND MOVING
LIFTING EYES
Be sure to use a forklift rated to lift more than the
appliance weighs as shown below. Fork length must
be at least 6 feet, if not, fork extensions should be
used. The stand is equipped with fork pockets just
above the angle iron base. The appliance is very
top heavy so spread the forks as far apart as pos-
sible.

even death. Contact your local building or fire officials about restrictions
and installation inspection in your area.
CLEARANCES
a. The Wood Stone MH-RFG-IR should have a minimum 1'’
clearance to combustibles from all sides, and 6" clearance to
combustibles from the top (See Figures 1a. and 1b on page 6). If
building a facade that will contact the appliance, 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 appliance
doorway, must be constructed of noncombustible building materials.
NOTICE: FOR STUCCO COVERED UNITS, (MODEL NUMBERS
ENDING IN “S”), 36” CLEARANCE TO COMBUSTIBLE BUILDING
MATERIALS IS REQUIRED
* When non-combustible building materials contact the body of the appliance,
the clearances to combustibles are transferred to those non-combustibles.
INSTALLATION CLEARANCES
c. Install this appliance only on a noncombustible floor surface.

FACADE DETAILS
Removeable Service Panel. Allows
access for service of gas and electrical
components. If this panel is not used,
access and air intake of equivalant
dimensions MUST be provided at the

GAS
TheWood StoneGasovens are equippedwitha 3/4" NPT gas connection.
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 TOTEST FOR LEAKS!
SV-1 and SV-2 are the gas control valves that operate under floor infrared
burnerand theinteriorradiantburner, respectively. SV-1is locateddirectly behind
the service/ intake panel and in front of the under floor infrared burner. SV-2 is
located under the oven to the rear left.
The manifold pressure test port for the infrared under floor burner
is a 1/8" NPT plugged tapping located near the left end of the burner
manifold.
The manifold pressure test port for the radiant (interior) 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.When checking this pressure,make
sure the flame is turned up to its maximum height using the knob on the
front of the oven.
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.
Factory specified individual burner manifold pressures for models
equipped to burn Natural Gas.

The following are the manufacturer’s recommendations for venting theWood Stone MS (Mountain
Series) RFG-IR 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 Listed to UL 103 and manufactured to
the specifications of a grease duct. Submit your venting plans to your local authorities before
OVEN VENTING
proceeding with your installation, as there may be additional requirements in your area.
There are two options:
1. A power ventilated building heating appliance chimney, listed to UL 103, also listed as a grease
duct, connected directly to the appliance flue collar.The power ventilator (fan) must be rated for a
minimum of 300 degrees F. Use a stack or curb mounted fan. Wood Stone does not recommend
the use of an in-line fan. A single wall chimney/duct connector (of unspecified length) may be
used to connect the appliance to the building heating appliance chimney as described above.Any
single wall ducting should be a minimum of 0.044" stainless steel or 16 ga. mild steel (0.055") and
must maintain a minimum of 18" clearance 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.
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

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.
