MANAGING THE OVEN FIRE
STARTING THE FIRE
Build a small kindling fire of 2�25–3 kg (5–7 lbs) of heavy, hardwood� We suggest using a fire starter (paraffin/sawdust stick) to
start the fire� Begin with (3) small pieces of wood (about 25–76 mm (1–3") diameter and 356–406 mm (14–16") in length)� The
fire should be located on side of the oven chamber opposite the radiant gas burner� The fire may be burned at the back of the
oven at the center provided the coal bed is kept at least 305 mm (1 ft�) away from the Radiant Burner� Wood may be burned at a
rate not to exceed 6�8 kg (15 lbs) per hour�
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 later in
this manual, or consult factory 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� 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 138 °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 by the Digital Hearth Temperature Readout and should not exceed 454 °C (850 °F)� Once the
desired temperature is reached, maintain it by the addition of wood as needed� Do not toss or throw wood against back or side
walls of oven—this may void the warranty� At the end of the work day, put removable Night Heat Retention Door(s) into door
opening to hold heat in the oven overnight�
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.
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�
MS-4 oven:
Maintain temperature using 1 log with 152–254 mm (6–10") of open flame working on the coal bed�
MS-5 & 6 ovens:
Maintain temperature using 1–1½ logs with 203–305 mm (8–12") of open flame working on the coal bed�
MS-7 oven:
Maintain temperature using 1½–2 logs with 203–356 mm (8–14") of open flame working on the coal bed�
IMPORTANT NOTES
•
One pound of properly cured, heavy, hardwood produces the potential of 1�9 kW (6,500 BTU/hr)�
•
The temperature sensor (thermocouple) is located at the center of the floor, one inch under the surface� The thermocouple will
give false readings 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, this heat-up procedure will need
to be repeated to avoid thermal shocking of the refractory stone which can cause excessive cracking�
DO NOT POUR OR SPRAY LIQUIDS ONTO THE OVEN DECK OR INTO THE OVEN INTERIOR
AS THIS CAN DAMAGE THE CERAMIC AND WILL VOID THE WARRANTY.
