DO NOT TURN THE OVEN ON ITS SIDE!
Moving a Wood Stone oven can present challenges to even the most experienced riggers� Secure the proper equipment and make
safety your first priority� Please don’t hesitate to call your distributor for technical support�
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�

GAS
DO NOT USE FLAME TO TEST FOR LEAKS
Wood Stone Gas ovens are equipped with a 3/4" (19 mm) female ISO-7 gas connection� Have a licensed gas installer
provide the hookup 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�
SV-1 AND SV-2 ARE THE GAS CONTROL VALVES THAT OPERATE THE UNDERFLOOR INFRARED BURNER AND
THE INTERIOR RADIANT BURNER, RESPECTIVELY.
NOTE: RFG models are only equipped with the SV-2 valve� SV-1 is located directly behind the service/ intake panel
and in front of the underfloor IR burner� SV-2 is located under the oven to the rear left�
The manifold pressure test port for the underfloor IR burner (served by SV-1) is a plugged nipple tap located near
the left end of the burner manifold. The manifold pressure test port for the radiant burner (served by SV-2) is a
plugged nipple tap located at the base of the T-junction between the SV-2 and the radiant/interior burner. Both
gas valves (SV-1 and SV-2) have an additional plugged nipple tap on the inlet side� The burner manifold pressures
have been adjusted and tested at the factory�
Wood Stone recommends that the oven be equipped with an individual shutoff valve and that this individual
shutoff valve (supplied by others) be left easily accessible. Wood Stone also recommends that inspection and
maintenance of the burners and gas piping connections of this appliance be performed at regularly scheduled
intervals and only by professional gas appliance service agencies.

OVEN VENTING
Wood Stone ovens should be vented in accordance with pertinent national, regional and local codes concerning such appliances;
check venting plans with the authority having jurisdiction before proceeding with installation�
The above statement taking precedence, Wood Stone Corporation recommends the following two venting options:
1. The Wood Stone MS Series ovens can be vented as a Type A appliance (with no flue connection), designed to be installed
under an exhaust hood (canopy)� The hood must be a Type 1 (grease rated) hood connected to a (grease rated) duct system�
The venting system must be designed and installed in accordance with all relevant codes pertaining to grease and smoke
producing commercial cooking appliances� Ovens that utilize solid fuel must be vented separately from any non-solid fuel
burning appliances� There may be requirements for interlocking the oven or its gas supply with the ventilation system� Check
with your local code official� Airflow should be adjusted according to the requirements specified by the hood manufacturer
and/or local codes�
OR
2. The oven is also approved as a Type B11 appliance, designed to be connected directly to a chimney which is installed in
accordance with all relevant local and national codes� The chimney system must be installed and constructed to the same
requirements as a duct that serves grease and smoke producing commercial cooking appliances� If venting the oven with this
method, the oven must be vented independently of other equipment� A suitable fan should be used at the end of the duct run
to ensure proper draft in all conditions� Wood Stone does not recommend using an in-line type fan� When installed, the fan
speed/air flow should be adjusted to attain the appropriate duct pressure at the oven flue collar:
DUCT PRESSURE
For gas-fired ovens without solid fuel: 0�25 mbar, (0�1" W�C�)
For any oven utilizing solid fuel: 0�35 mbar, (0�14" W�C�)
This pressure may be checked by inserting the pressure test probe up through the oven doorway to the point where the
duct is connected to the oven flue collar�
FAN TEMPERATURE RATING
The fan must also be of a suitable temperature rating�
For gas-fired ovens without solid fuel the fan must be rated for a minimum of 150 °C (300 °F) continuous�
INTERLOCK SYSTEM
There may be requirements for interlocking the oven or its gas supply with the ventilation system� Check with your local
code official�

FLUE ADAPTER
FLUE ADAPTER
MOUNTAIN SERIES OVENS: FLUE ADAPTER
The flue adapter unit is designed to facilitate connection to a round duct� Use the stainless steel screws and sealant provided to
attach the flue adapter to the exhaust outlet on the oven if it is not already installed� Note: MS-4 ovens come standard with a round
203mm (8") collar and do not require the flue adapter for a direct connection�
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� All duct must be grease-rated duct� 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�

VENTING DO’S AND DON’TS
VENTING DO'S AND DONT'S
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 1 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 see drawings on the following pages.

VENTING DO’S AND DONT’S
DIRECT CONNECT VENTING EXAMPLES
Example 2 is not acceptable because the
combustion air intake is blocked, preventing
combustion air from reaching the oven
burners� The burners will not function properly,
and this will also lead to damage of oven
components�
Example 1 shows a proper installation�
Enclosure around the oven is completely
sealed so that the only air entering the space
beneath the oven comes through the oven
service panel�

HOOD INSTALLATIONS
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 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� Note that in an MS-5, 6 or 7 model, the oven has the round flue adapter
attached� The adapter may prevent the proper positioning of the hood� The flue adapter is attached with screws� (The MS-4
does not require an adapter�) Simply remove the screws to remove the adapter if it is in the way�
2. Pull the hood forward so that the notch, 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� 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�
