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 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.
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: MS-4 ovens come standard with a round 8” O.D. collar and do not require the flue adapter for a direct connection.
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 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)-RFG-W, Revised May 2015. Doc no: M0032.
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.

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.
DAILY OPERATION Mountain Series Installation and Operation Manual DAILY OVEN OPERATION OVERVIEW DAILY START UP 1. Remove the night door(s). 2. Push ON/OFF button. Using the Flame Height Control Knob, turn the radiant flame to its highest setting. Check your temperature after approximately one hour. If you are close to your desired temperature, reduce your flame to the Holding Flame setting that corresponds to your desired temperature.
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.
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.
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.
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.
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.
