INITIAL START-UP
INITIAL STARTUP
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� 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 BUILDING THE FIRE
Set the thermostatic hearth temperature to 100 °F (factory settings)� Note that the control panel will display “LO” until
the oven reaches 100 ° F� To adjust the oven’s thermostatic hearth temperature setting, simply press the arrow button
corresponding to the direction in which you would like the setting to go� If the thermostatic set point is raised above
the actual hearth temperature, the underfloor IR burner should activate� Note: It is only possible to program the floor’s
thermostatic Hearth Set Point to temperatures from 100–800 °F� Once the proper temperature for your application have
been established, there should be little or no need to change the Hearth Set Point�
DAY ONE
1.
Build a small kindling fire of newspaper and 5-7 lbs� of heavy hard wood� We suggest using a “fire starter” (paraffin/
sawdust stick) to start the fire� Begin with (3) small pieces of wood (about 1–3" diameter and 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 inside and of a size that doesn’t permit the flame to go up the flue� Slowly bring the oven temperature up to
300–400 °F� Maintain this fire for 4–5 hours�
2. Once the oven temperature has reached and maintained a temperature of 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 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 of heat-up, the oven does not exceed 550 °F within the first 8 hours� If your goal is to cook at higher temperatures,
the oven should only be brought up to 550 °F on day one� Once the oven has reached 550 °F, more wood may be added
to the fire as necessary to bring the oven to the desired operating temperature� The amount of wood required to bring
the oven to the specified temperatures may vary depending on the type and quality of the wood� Never use any type of
flammable liquid or fuel to start a fire in a Wood Stone oven. Doing so could cause a dangerous situation and/
or damage to the oven ceramic.
AFTER THE FIRST DAY HEAT-UP:
Raise the infrared set point to desired hearth temperature� If the goal is to cook
between 500–530 °F, the set point should be 500 °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 AND WILL STOP WITHIN A FEW DAYS.
