Note: 0" side and top clearance to noncombustible materials.
FACADE DETAILS Mountain Series Installation and Operation Manual Wood Stone Mountain Series (MS-) ovens carry an ETL Sanitation listing. The oven interior only is ETL listed to NSF/ ANSI Standard 4. This means that the surfaces of the oven which are meant to be left exposed after the facade has been put in place have been evaluated from the standpoint of sanitation and food safety and found to comply with NSF/ ANSI Standard 4.
OUTDOOR INSTALLATIONS Mountain Series Installation and Operation Manual OUTDOOR INSTALLATIONS The Mountain Series (MS-) model ovens are ETL approved for outdoor installation. When installed outdoors, the open area beneath the oven must be enclosed, with the exception of the perforated area on the front Service Panel (or storage box) for air intake. The oven may be installed in a weatherproof enclosure.
GAS SPECIFICATIONS Mountain Series Installation and Operation Manual 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-1 is the gas control valve that operates the Underfloor Infrared (IR) burner.

ELECTRICAL SPECIFICATIONS Mountain Series Installation and Operation Manual Incoming power should be connected to the terminal strip located in the Transformer Junction Box beneath the oven (see diagram below). The standard oven model comes configured for connection to a 120 VAC circuit. The oven can be ordered configured for connection to a 240 VAC circuit. Always refer to the equipment data plate beneath the oven to verify the proper voltage. The voltage is also specified on the Transformer Box cover.
VENTING Mountain Series Installation and Operation Manual THIS MODEL MUST BE VENTED AS A SOLID FUEL APPLIANCE The following are the manufacturer’s recommendations for venting the Wood Stone MS (Mountain Series) W-IR 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.
VENTING Mountain Series Installation and Operation Manual NOTE: If your MS-5, MS-6 or MS-7 oven is ordered from Wood Stone without a hood, it will have a round flue adapter installed to facilitate direct connection to a round duct. If the oven is to be installed under a hood, it MAY be necessary to remove the round adapter to properly position the hood. This is done by removing the screws that attach the adapter to the oven. Please contact Wood Stone if you have any questions. Collar I.D.
VENTING Mountain Series Installation and Operation Manual 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.
FLUE ADAPTER Mountain Series Installation and Operation Manual 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: 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.
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.
VENTING DO’S AND DON’TS Mountain Series Installation and Operation Manual DIRECT CONNECT VENTING EXAMPLES Equal air pressure inside and outside of oven room Stud wall Facade surface Air intake area on removable Service Panel properly exposed Exhaust flow direction is normal Example 1 shows a proper installation. The enclosure around the oven is completely sealed so that the only air entering the space beneath the oven comes through the oven Service Panel.
VENTING DO’S AND DON’TS Mountain Series Installation and Operation Manual DIRECT CONNECT VENTING EXAMPLES Neutral room air pressure Equal air pressure inside and outside of oven room Low pressure is created by HVAC or any air moving equipment outside the oven room Exhaust flow direction is reversed Exhaust air is pulled backwards through oven burners An added vent intended to increase air supply Airflow to oven is altered as air moves from normal to low pressure Example 3 shows an incorrect installat
VENTING DO’S AND DON’TS Mountain Series Installation and Operation Manual DIRECT CONNECT VENTING EXAMPLES Low pressure area Air flow Equal air pressure inside and outside of oven room Exhaust flow direction is nomal False ceiling Addition of an oven room ceiling isolates the oven from low pressure areas thus equalizing air pressure and allowing normal airflow to the oven burners.
VENTING DO’S AND DON’TS Mountain Series Installation and Operation Manual 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 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).
VENTING DO’S AND DON’TS Mountain Series Installation and Operation Manual 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.
VENTING DO’S AND DON’TS Mountain Series Installation and Operation Manual Incorrect installation. No flashing has been installed so air being pulled up the sides of the oven from beneath. Unacceptable venting Exhaust stack Stud wall Side view of properly installed hood Hood Airflow shield Facade surface Acceptable venting An ongoing program of product improvement may require us to change specifications without notice. WS-MS-(4, 5, 6, 7)-W-IR, Revised May 2015. Doc no: M0036.
VENTING DO’S AND DON’TS Mountain Series Installation and Operation Manual CLEARANCES The Type 1 hood requires an 18-inch clearance to combustible construction. Clearances to limited combustibles may be reduced per NFPA 96 and/or your local codes. Approved clearance reduction methods may also be used, per NFPA 96 and/or your local codes. (These reductions are applicable to the hood and/or duct only, NOT to the oven.) Consult with your local inspector regarding approved methods.

CONTROLLER Mountain Series Installation and Operation Manual W-IR AND WG OVEN CONTROLLER FUNCTIONS Hearth Heat indicator light Indicates that the pilot for the iunderfloor IR burner is lit. This light will go off whenever the hearth temperature is above the Hearth Set Point. Power indicator light Indicates the oven is turned ON. POWER HEARTH HEAT Hearth Temperature display Displays temperature of oven floor (hearth). Sensor is embedded 1” below surface of hearth.
INITIAL STARTUP INITIAL START-UP Mountain Series Installation and Operation Manual READ BEFORE BUILDING FIRST FIRE Note: The W-IR model is a wood burning oven with an Underfloor Infrared (IR) burner mounted underneath the floor to assist in speeding heat-up and manage the hearth temperature. The wood fire in this oven is the main heat source. Your oven was cured at the factory. However in the course of shipment, storage on site, etc. the ceramic materials will have absorbed moisture.
WOOD BURNING Mountain Series Installation and Operation Manual IMPORTANT NOTES • One pound of properly cured, heavy, hard wood produces the potential of 6,500 BTU/hr. • The temperature sensor (thermocouple) is located one inch under the surface, approximately 1 ft. back from the center of the oven. The thermocouple will display a much higher temperature than the surrounding deck temperature if the fire is placed on top of it.
WOOD BURNING Mountain Series Installation and Operation Manual ASH DISPOSAL At the start of the following work day, pull the spent fuel (fly ash) off of the coal bed using your brass bristle brush. Remove with ash shovel and place ashes into an ash dolly (metal container with a tight fitting lid). The closed container of ashes should be placed on a non-combustible floor or on the ground, a safe distance from all combustible materials pending final disposal.
MAINTENANCE Mountain Series Installation and Operation Manual DAILY MAINTENANCE OVEN INTERIOR 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.
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.
