PG 37 OF 48M0037�09 SEPTEMBER 2019Mountain Series CEInstallation and Operation ManualW-IR INITIAL START-UPINITIAL W-IR OVEN START-UP PROCEDUREThe W-IR model is a wood burning oven with an Underfloor Infrared burner to assist in speeding heat-up and to assist inmanaging 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 haveabsorbed moisture� It is critical that the procedure below be followed to ensure that this moisture is driven from the ceramic in acontrolled fashion� This will minimize cracking and prevent damage to the oven that could otherwise occur by bringing the ovento temperature rapidly the first time it is used� This initial procedure need only be followed the first time the oven is fired and/or ifthe oven has not been used for an extended period of time�BEFORE BUILDING THE FIRENote: W-IR ovens use the Type 2 Controller shown in the GAS CONTROLLERS section of this manual�Set the thermostatic Hearth Set Point to 38 °C (100 °F) (factory settings)� Note that the Hearth Temperature display will read “LO”until the oven reaches 38 °C (100 °F)� To adjust the oven’s thermostatic hearth temperature setting, simply the Up or Down arrowbutton corresponding to the direction in which you would like the setting to go� If the thermostatic Hearth Set Point is raisedabove the actual Hearth Temperature, the Underfloor IR burner should activate� Note: It is only possible to program the floor’sthermostatic Hearth Set Point to temperatures from 38–427 °C (100–800 °F)� Once the proper temperature for your applicationhave been established, there should be little or no need to change the Hearth Set Point�DAY ONE1. Build a small kindling fire 2�25–3 kg (5–7 lbs) heavy hard wood� We suggest using a “fire starter” (paraffin/sawdust stick) tostart the fire� Begin with (3) small pieces of wood (about 25–76 mm (1–3") diameter and 356–406 mm (14–16") in length)�Build the fire directly on the floor of the oven against the side or back of the dome� The fire should be built far enough insideand of a size that doesn’t permit the flame to go up the flue� See the BURNING WOOD SAFELY section of this manual formore detail� Slowly bring the oven temperature up to 150–200 °C (300–400 °F)� Maintain this fire for 4–5 hours�2. Once the oven temperature has reached and maintained a temperature of 150–200 °C (300–400 °F) for 4–5 hours,increase the oven temperature by increasing the size and amount of wood being used� Based on what is already burning,gradually increase the amount of wood per hour� This will bring the oven temperature up to 260–288 °C (500–550 °F)�NOTE: THE MORE WOOD ADDED TO THE FIRE, THE HOTTER THE OVEN WILL GET. It is recommended that on the first day ofheat-up, the oven does not exceed 288 °C (550 °F) within the first 8 hours� If your goal is to cook at higher temperatures, theoven should only be brought up to 288 °C (550 °F) on day one� Once the oven has reached 288 °C (550 °F), more wood may beadded to the fire as necessary to bring the oven to the desired operating temperature� The amount of wood required to bring theoven to the specified temperatures may vary depending on the type and quality of the wood� Never use any type of flammableliquid or fuel to start a fire in a Wood Stone oven. Doing so could cause a dangerous situation and/or damage to theoven ceramic.AFTER THE FIRST DAY HEAT-UP: Raise the Hearth Set Point to desired hearth temperature� If the goal is to cook between260–288 °C (500–550 °F), the Hearth Set Point should be 288 °C (550 °F)� Remember, the wood fire is the main heat source�During the first few days of operation, small amounts of water may appear dripping from the oven� This is normal andwill stop within a few days�Small “crazing” cracks may 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 your local distributor for evaluation�DO NOT OVER-FIRE THIS OVEN. IF FLAMES ARE SPILLING OUT OF THE DOOR OPENING, OR IF OVENFLOOR TEMPERATURE EXCEEDS 454 °C (850°F), THEN YOU ARE OVER-FIRING THE OVEN.
