UNLOADING AND MOVING
Mountain Series
Installation and Operation Manual
LIFTING THE OVEN
1. USING A CRANE
The oven arrives with four lifting eyes 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.
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
Be sure to use a forklift rated, and forks the minimum length, as shown
in the table below. If necessary, fork extensions must be used so the
forks extend through the fork lift pockets to the opposite side of the
stand. Lift from either side as shown. Do not lift from the front or back.
The oven is very top heavy, so spread the forks as far apart as possible.

3. USING A PALLET JACK
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 OR INCLINE ON A PALLET JACK IS NOT SAFE!
4x4 post
DO NOT TURN THE OVEN ON ITS SIDE!
Contact Wood Stone if the oven must be turned on its side for specific instructions. Moving a Wood Stone oven can
present 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.
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.

VENTING
Mountain Series
Installation and Operation Manual
The following are the manufacturer’s recommendations for venting the Wood Stone MS (Mountain Series) RFG-IR-W
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. This is a wood/gas combination oven and must be
vented as a solid fuel piece of equipment. Due to the possibility of sparks entering the system, exhaust systems serving
solid fuel equipment must be vented separately from other non-solid fuel equipment. The duct serving this oven should
be inspected at least twice a month during the first two months of operation, to establish rate of creosote buildup and
necessary cleaning schedule. Typically, we recommend monthly cleaning for all solid fuel ovens. Submit venting plans
to your local authorities before proceeding with your installation, as there may be additional requirements in your area.
There are two venting options.
VENTING OPTION 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 450 °F. Wood Stone does not recommend the use of an in-line
fan. A field built grease duct, constructed and installed to the specifications of a grease duct as detailed in NFPA 96 or
the International Mechanical Code, may also be used.
A static pressure of -0.14 inches water column is necessary at the oven flue collar to ensure that flue gas temperatures
do not exceed 450 °F at the fan inlet. This measurement may be taken by inserting the probe of the magnahelic gauge
through the oven doorway, upwards to the oven flue collar. 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.
See table below for CFM required to attain the specified static pressure. NOTE: Solid fuel burning ovens must be vented
separately from non-solid burning equipment.

VENTING OPTION 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. Note that the notch of the hood is even with the front edge of the oven. The hood must
be installed in accordance with the hood manufacturer’s instructions, and with the Standard for Ventilation Control and
Fire Protection of Commercial Cooking Operations, NFPA 96 and/or the applicable local and national codes. Refer to the
exhaust hood manufacturer’s recommendations for inspection, maintenance and cleaning. Solid fuel burning ovens must
be vented separately from non-solid fuel burning equipment.
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. Due to the possibility of sparks entering the
duct, exhaust systems serving solid fuel equipment MUST not be combined with exhaust systems serving other (nonsolid fuel) equipment. This model is rated as solid fuel equipment and must be vented as such.
VERY IMPORTANT!
WOOD STONE RECOMMENDS THAT YOU CONSULT WITH A QUALIFIED MECHANICAL ENGINEER
AND SUBMIT YOUR VENTING PLANS TO LOCAL CODE AUTHORITIES

FIRE SUPPRESSION
Check with your local code officials to see if fire suppression is required in your area. If fire suppression is required,
you must vent the oven using a Type 1 hood constructed and installed in accordance with NFPA 96. The fusible link in
the hood must be rated at 450 °F minimum. Wood Stone offers Listed exhaust hoods for our ovens that are pre-piped
for ANSUL R-102 fire suppression. All installations are subject to the approval of the local authority having jurisdiction.

VENTING DO’S AND DON’TS
Mountain Series
Installation and Operation Manual
VENTING DO’S AND DON’TS
When installing a Wood Stone Mountain Series oven there are some basic guidelines to follow regarding oven venting
that will help ensure proper operation and performance of the gas burners on the oven. These guidelines will also help
prevent damage to the oven's gas and electrical components due to improper venting and installation. Damage caused
by improper venting and installation is not covered by the oven warranty. This information applies to all Wood Stone
Mountain Series (MS) ovens equipped with one or more gas burners.
Most Wood Stone Mountain Series ovens are built into some sort of wall structure or enclosure. This creates the potential
for different venting scenarios that can be detrimental to the operation and performance of the oven burners. Here are
some basic rules that to follow that will ensure a properly functioning oven installation. Illustrated examples are included
on the following pages.
RULE 1
The ONLY pathway for air to enter the space beneath the oven should be at the front of the oven at the perforated
opening in the oven Service Panel provided with the oven, or on ovens equipped with an optional Storage Box, through
the perforations provided on the oven Storage Box. This will eliminate the chance of air movement or cross drafts
beneath the oven that can disrupt the oven burners.
RULE 2
DO NOT block the flow of air through the front Service Panel. It is required to provide necessary combustion air to the
oven burners. Airflow and service access MUST be provided from the front of the oven only at this Service Panel. DO
NOT relocate the oven air intake (see Rule 1).
RULE 3
To ensure proper venting of the oven, you must use an appropriate exhaust fan as described in this manual. There must
also be an adequate source of make-up air provided to your kitchen space—the room that the oven opens into. The
make-up air supply should not point directly at the oven. Other than the oven Service Panel, do not provide make-up air
or other ventilation into an enclosure that surrounds the oven (see Rule 1). Without proper make-up air the oven, (or any
gas equipment), will not vent and operate correctly.
Please review the illustrations on the following pages.

In addition to the information given for installations using the direct connect venting method, the following information
applies to installations where the oven is being vented using a Listed Type 1 hood. Also refer to the OVEN VENTING
section earlier in this manual.
PROPER MOUNTING POSITION FOR THE WOOD STONE HOOD
1. Center the hood from side to side on the oven (A). Note that in an MS-5, 6 or 7 model, the oven may have the round
flue adapter attached. The adapter can prevent the proper positioning of the hood. The flue adapter is attached with
screws. Simply remove the screws to remove the adapter if it is in the way.
2. Pull the hood forward so that the notch (B), as viewed from the side of the hood, lines up with the front edge of the
top of the oven.
3. Secure the hood to the top of the oven using #10 self-tapping screws. The flanges on the hood are pre-drilled (C).
Screw directly into the top of the oven to secure the hood.
4. Attach grease-rated duct to the outlet on the hood. The hood captures over the oven flue collar and oven doorway.
No connection is made to the oven flue collar.

HOOD INSTALLATION WITH DECORATIVE FACADE WALL/OVEN ENCLOSURE
For installations where a hood is being used with a decorative facade wall or oven enclosure, it will be necessary to both
seal the gap between the facade wall and the top of the oven, and the gaps at the sides of the hood between the facade
wall and the front of the oven. This will prevent air from being pulled up the sides of the oven from below by the hood. It
will also prevent debris, etc. from falling into the facade wall.

MANTLE MOUNTING
Mountain Series
Installation and Operation Manual
The initial steps are the same for mounting either a stainless mantle or a bracket for a granite mantle.
1. Begin by installing the threaded studs
into the clip nuts below the oven
doorway (3 or 4 turns is sufficient).
2. Position the mantle (or bracket) on the
oven, making sure the rear flange rests
on the floor of the oven (you may need
an extra pair of hands).
3. Place one stainless steel washer and a
cap nut onto each stud. Tighten the cap
nuts so the mantle is securely held in
place.
4. Using the high temperature silicone
(provided), fill any gaps between the
oven hearth and the mantle flange.
Gaps between the mantle flange and
the stainless steel doorway frame
may also need to be filled with a small
amount of the silicone sealant. Clean
up any sealant before it dries.
INSTALLATION OF GRANITE
After completing the steps outlined above, apply a generous amount of silicone adhesive (provided) to the top of the steel
mantle bracket.
Put the stone in place and apply light
pressure to seat it properly. Make sure
that the angle in the granite lines up with
the angle in the bracket. Allow the sealant
to set for several hours before filling
any gap between the stone slab and the
metal bracket with the silicone sealant
(provided). Clean up any sealant before
it dries.

INITIAL START-UP
Mountain Series
Installation and Operation Manual
INITIAL OVEN START-UP PROCEDURE
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 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. This initial procedure need 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.
BEFORE GETTING STARTED
1. Make sure main gas supply is on (valve parallel with gas line).
2. Make sure the switch on the Honeywell gas control gas valve (SV-2) is in the ON position. This is located beneath
the oven.
3. Make sure that the venting system has been tested and approved for operation and is on.
FIRST DAY
1. Remove the Night Heat Retention Door(s). Push the ON/OFF button on Controller. It may take awhile for the gas to
purge all the air from the gas lines.
2. Allow oven to operate with the radiant flame at its lowest setting for one hour.
3. After one hour, raise radiant flame to 25% (~6 inch flame, 2 on the Flame Height Index Scale). Hold this setting for
4 hours.
4. After 4 hours at 25% flame, raise to 50% flame (3 on the Flame Height Index Scale) and hold for at least another
4 hours or until the temperature reaches 500 °F.
5. Once the temperature reaches 500 °F the oven is ready for use. If you will be shutting the oven down, see the
instructions that follow.
TURNING OFF THE OVEN
1. Push ON/OFF button. All gas will go off, including the pilot. Put the Night Heat Retention Door(s) in place to retain
heat.
NOTE: Always wait 5 minutes before restarting the oven. Never run the oven with the Night Heat Retention Door(s)
in place.
NOTE: Small “crazing” cracks will occur with normal heating and cooling. They will not effect the performance or durability
of the oven. If cracks of 1/8" or more develop, contact Wood Stone for evaluation.

FLAME HEIGHT CONTROL
Mountain Series
Installation and Operation Manual
DETERMINING THE APPROPRIATE FLAME HEIGHT
For each specific configuration of oven there is a system that determines what the desired flame height will be. Each
flame height corresponds to a saturated floor temperature. Several factors need to be accounted for in order to determine
this relationship for each oven. Burning wood simultaneously in the oven will influence the settings below.
USING THE FLAME HEIGHT INDICATOR SCALE
Heat Up Flame: Set Temperature Control Knob Pointer at “5” (highest setting) on the Flame Height Index Scale until
desired temperature is reached.
Holding Flame: Set the flame height to “3” (~8–9" flame) on the Flame Height Index Scale for desired temperature
of 570–600 °F. Set flame height to “2” (~5–6" flame) on the Flame Height Index Scale for desired temperature of
450–480 °F.
Cooking Flame: After introducing the pizza/product into the oven, visually raise the flame to approximately 3 inches
higher than the Holding Flame.
Return the Temperature Control Knob to the Holding Flame position after removing the pizza/product from the
oven.
THE COOKING FLAME HAS TWO PURPOSES:
1. To bake the top of the pizza/product as fast as the bottom of the pizza/product.
2. To help replace heat to the floor (hearth) that is lost during production cooking.
Note: The settings recommended on the Flame Height Index Scale for specific flames are based on ovens that have
been installed according to specifications. Individual results may vary slightly.

MAINTENANCE
Mountain Series
Installation and Operation Manual
CLEANING THE OVEN
Clean as needed­—multiple times per hour depending on production. 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
brushing towards the doorway where it can be easily removed with a dough cutter or spatula. For deeper cleaning, use
a brass bristled brush. The oven floor can be then cleaned with a damp (not wet) rag wrapped around the 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.
NEVER PLACE ANYTHING IN OR ABOVE THE RADIANT FLAME.
NEVER SWEEP DEBRIS INTO THE RADIANT BURNER. THIS CAN CAUSE THE BURNER TO CUT OUT, DAMAGE
BURNER COMPONENTS, AND/OR EFFECT BURNER PERFORMANCE. PROBLEMS CAUSED BY DEBRIS IN
THE RADIANT BURNER WILL NOT BE COVERED BY THE OVEN WARRANTY.
NEVER USE ICE, EXCESSIVE WATER, ANY LIQUID, OR ANY TYPE OF CLEANING CHEMICAL ON THE OVEN
FLOOR. DOING SO CAN SEVERELY DAMAGE THE OVEN CERAMIC AND THIS DAMAGE WILL NOT BE COVERED
UNDER WARRANTY.
NIGHT HEAT RETENTION DOORS
The door(s) are used for nighttime heat retention. Do not operate the oven with doors in place.

WOOD BURNING
Mountain Series
Installation and Operation Manual
WS-MS-RFG-W and RFG-IR-W models are approved to allow the burning of wood in the cooking chamber in addition
to the gas burners. When burning wood, the fire should be placed to one side of the oven chamber, as close to the door
opening as is possible (this is often described as the 8 o’clock or 4 o’clock position). Burn a maximum of 15 lbs. of wood
per hour. If flames spill out of the doorway, or the oven temperature exceeds 850 °F, you are over firing the oven.
Make every effort to keep ash and other debris out of the radiant burner
well. Do not use the radiant burner as a “backstop” when shoveling ash
and/or coals out of the oven. Burner problems resulting from debris
or ash in the burner well will not be covered by the oven warranty.
Using the oven floor brush and ash shovel, move debris only toward the
oven doorway and dispose of safely.
NOTE: Ovens burning solid fuel require a more frequent
maintenance schedule. Call with questions regarding maintenance
frequency.
See the FUELWOOD FACTS section at the end of this manual for more
information on burning wood.
DO NOT USE THE RADIANT BURNER TO IGNITE WOOD OR
SUPPORT THE WOOD FIRE.
Radiant burner

fire locations
Oven Doorway
Wood should be stored and handled in accordance with the
recommendations outlined in NFPA 96.
The interior floor and dome of the oven do not require creosote or soot
removal. The oven flue and exhaust system will require inspection and
cleaning. The exhaust system must be inspected and cleaned per the
manufacturer’s and or local code official’s recommendations. Wood
Stone recommends cleaning and inspection at least monthly on any
ventilation system serving solid fuel equipment.
DISPOSE OF ASH PER THE FOLLOWING:
1. Place ashes into a metal container with a tight fitting lid.
2. Place the closed container of ashes on a non-combustible floor or on
the ground.
3. Place the closed container of ashes well away from all combustible
materials, pending final disposal.
4. Retain the ashes in the closed container until all the cinders have
thoroughly cooled. Ashes can then be disposed of safely.
Wood Stone’s stainless steel ash shovel and double compartment ash
disposal system offer a safe and convenient way to dispose of ash. Specification
sheets may be viewed on the Wood Stone website under Tools & Accessories

PERIODIC THERMAL CLEANING
Mountain Series
Installation and Operation Manual
ESTABLISHING A THERMAL CLEANING SCHEDULE
Wood Stone ovens are typically operated at temperatures which preclude the need for cleaning of the interior walls and
ceiling (the dome) of the oven. If, however, you routinely operate the oven at floor temperatures lower than 450 °F, you
may notice a buildup on the interior walls and/or ceiling of the oven. If this is the case, use the following procedure to
periodically clean the oven. The frequency of thermal cleaning will be determined by the amount of buildup experienced.
THERMAL CLEANING
If a Wood Stone gas-fired oven is operated at low temperatures (below 450 °F), it is possible that grease from food could
condense on the walls and ceiling of the oven. To remove the grease that has accumulated on the walls and ceiling of the
oven, simply turn the radiant flame to its highest setting. Monitor the floor temperature displayed on the Controller. When
the floor reaches 600 °F, lower the flame slightly so as to maintain the oven floor temperature near 600 °F for about
an hour. Once the oven dome appears clean, allow the oven to return to normal operating temperatures and continue
normal operation.

SAFETY CONSIDERATIONS
Mountain Series
Installation and Operation Manual
IMPORTANT SAFETY CONSIDERATIONS
Solid fuel exhaust contains creosote and other substances that accumulate in ducting, creating a risk of fire. The rate
of accumulation will vary with respect to flue gas temperature, wood type and moisture content. Frequent, regularly
scheduled, thorough flue cleaning is the best way to minimize the risk of flue fires.
CREOSOTE - AND THE NEED FOR ITS REMOVAL
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form
creosote. The creosote vapors condense in the relatively cool oven flue of a slow-burning fire. As a result, creosote
residue accumulates in the duct. When ignited, this creosote makes an extremely hot fire. The duct serving this oven
should be inspected at least twice a month during the first two months of operation, to establish rate of creosote buildup
and necessary cleaning schedule. If creosote or soot has accumulated, it should be removed to reduce the risk of a flue
fire. The interior floor and dome of the oven do not require creosote or soot removal.
The oven flue and exhaust system will require inspection and cleaning. The exhaust system should be inspected and
cleaned per the manufacturer’s and or local code official’s recommendations. Wood Stone recommends cleaning and
inspection at least monthly on any ventilation system serving solid fuel equipment.

FUELWOOD FACTS
Mountain Series
Installation and Operation Manual
WHAT TYPE OF WOOD SHOULD YOU USE TO FIRE YOUR SOLID FUEL COOKING EQUIPMENT?
The answer to this question depends on several considerations: geographical location, availability and relative cost of various
fuelwood species and individual preferences regarding the flavor qualities of various wood types. There are a wide variety of good
fuelwood species in all geographic locations. Each species of wood has different characteristics. The table below should help weigh
the pros and cons of various types of wood. Wood from conifers (pine trees) is not recommended due to its poor fuelwood characteristics (low weight, low-med heat, poor coaling, high sparking and high residual creosote).

*The desirability of
various fragrances
is largely a matter of
personal preference.
Whichever type of wood you use, MAKE SURE YOU KNOW THE MOISTURE CONTENT. Properly seasoned wood contains 20%
moisture or less. If wood contains more than 20% moisture, it should not be accepted for use. Wood should be stored off the ground
and out of the rain in an environment that allows good air circulation so that the drying process can continue. Wet wood is the most
common operational difficulty associated with wood-fired cooking equipment. Wood Stone’s optional Mini-Ligno E Wood Moisture
Meter can save you from paying for water when you thought you were paying for wood (see the Tools & Accessories section of
woodstone-corp.com).
Calculate your approximate monthly, daily and hourly fuel-wood costs using the following formulas:
The cost of well-seasoned hardwood varies greatly with geographical location.
Cost per month = A x C
Cost per day = A x C
Cost per hour = A x C
30
30
12 hr day
A = Cost/cord (from wood supplier)
B = lb/cord (from above table)
C = Cords/mth (from experience, or call Wood Stone for an estimate)
When burned, a pound of any wood releases approximately 6500 BTU/hr, so it is better to compare the price
of wood by the pound rather than by the cord. A full cord of wood measures 4' x 4' x 8' when stacked.
Cost per lb = A
