Installation and Operation Manual
W-IR DAILY OPERATION
IMPORTANT NOTES
•
One pound of properly cured, heavy, hard wood produces the potential of 1�9 kW (6,500 BTU/hr�)
•
The temperature sensor (thermocouple) is located one inch under the surface, approximately 305 mm (1 ft�) back from the
center of the oven� The thermocouple will read a much higher temperature than the surrounding deck temperature if the fire is
placed on top of it�
•
If at anytime the oven is allowed to cool to room temperature for an extended period of time, the Start-Up Procedure will need
to be repeated to avoid thermal shocking of the oven ceramic which can cause excessive cracking�
•
Small “crazing” cracks will occur with normal heating and cooling� They will not effect the performance or durability of the oven�
If cracks of 3 mm (1/8") or more develop, contact your local distributor for evaluation�
THE FIRE
(see Wood Burning section later in this manual for additional information)
Use only seasoned hardwoods with a moisture content of 20% or less� Use of soft woods, such as pine, cedar, hemlock etc�, and
wet or “green” wood, will cause a build-up of residue throughout the exhaust system� (See the FUELWOOD FACTS section of this
manual, or consult your local distributor for information on what types of wood can be used for oven fuel�)
The fire should be ignited a couple of hours before the oven needs to be at cooking temperature, and can be located practically
anywhere in the oven, far enough inside and of a size that doesn’t permit the flame to go up the flue� Once the oven is being used
daily, the fire can be ignited using still glowing coals from the previous day’s fire� The oven is heated more evenly and effectively
by the fire positioned on the side rather than in the rear of the oven�
Adding about 2�25–3 kg (5–7 lbs) of wood per hour should bring the oven temperature up about 38 °C (100 °F) per hour (this
will vary slightly depending on the type and moisture content of the wood and the size of the oven)�
The floor temperature is indicated in the Hearth Temperature display
on the Controller and should not exceed 454 °C (850 °F)�
Once the desired temperature is reached, maintain it by adding wood as needed� Do not toss or throw wood against back or side
walls of oven—this will damage the oven and void the warranty�
At the end of the work day, turn off the oven and put removable stainless steel Heat Retention Night
Door(s) into door opening to hold heat in the oven overnight� Note: Door(s) should only be used when
the oven is OFF�
HOW TO READ HEARTH TEMPERATURE
The floor temperature is continuously displayed by the Controller in the top window labeled
� This
reading is being taken by a thermocouple about 25mm (1") below the floor surface, so the actual
surface temperature may be somewhat different�
MANAGING THE FIRE / TEMPERATURE
These suggestions will normally produce an oven floor temperature of 260–315 °C (500–600 °F)�
If you need to achieve higher temperatures, use a little more wood� For lower temperatures,
use a little less wood�
4' oven:
Maintain temperature using 1 log with 152–255 mm (6–10") of open flame�
5' and 6' ovens:
Maintain temperature using 1–1½ logs with 203–305 mm (8–12") of open flame�
7' oven:
Maintain temperature using 1½–2 logs with 203–355 mm (8–14") of open flame�
TURNING OFF THE BURNER
Push the ON/OFF button on the Controller to turn the Underfloor IR burner OFF� The burner will go out and the digital readout on
the Controller will go blank�
DO NOT OVER-FIRE THIS OVEN. IF FLAMES ARE SPILLING OUT OF THE DOOR OPENING,
OR IF OVEN FLOOR TEMPERATURE EXCEEDS 454 °C (850°F), THEN YOU ARE OVER-FIRING THE OVEN.
Night Heat Retention Doors
NOTE:
Never operate
this appliance with the
stainless steel Night Heat
Retention Door in place.
