VENTING & CLEARANCES
VENTILATION
The plancha must be vented with a Listed Type 1 hood. This appliance must be installed and vented in
accordance with NFPA 96 and all relevant national and local codes, subject to the approval of the local
authority having jurisdiction.
CLEARANCES
If this grill is not properly installed a fire may result. To reduce the risk of fire, follow these installation instructions. A
major cause of appliance related fires is failure to maintain required clearances (air spaces) to combustible materials.
It is of utmost importance that this appliance be installed only in accordance with these instructions.
Allow a minimum of 12 inches of clearance to combustible construction or materials from sides and back.
Allow a minimum of 3 inches of clearance to non-combustible construction to allow cooling air to enter the vents on
the sides and back of the unit. Do not block the air vents on the sides, back or beneath the appliance.
WARNING: Do not pack required air spaces with insulation or other material
Electrical supply cords should be routed so that they are not subjected to the heat coming off of the plancha cooking
surface. We recommend locating the electrical outlets at a height that is below the level of the Plancha cooking
surface to avoid heat damage to the electrical cords.

Use the power switch to turn on the Plancha.
There are (4) temperature controls on the front of the control box. Use these to set the desired temperature for each zone.
Zones are marked above the temperature control knobs. The Heater Indicator Light for each zone will be illuminated
until the zone reaches the temperature set on the Temperature Control Knob or when the temperature drops below the
temperature set on the Temperature Control Knob.

Grease/Debris Tray
CLEAN THOROUGHLY BEFORE FIRST USE
A vegetable oil cooking spray is applied to the cook surface at the factory to help protect from corrosion during shipping.
The cook surface must be thoroughly cleaned before use. Follow these instructions:
1. Set the Temperature Controls to LO. Make sure the Grease/Debris tray is in place.
2. Turn the Plancha ON and allow to heat for 5 minutes. Then turn the Plancha OFF and wait for 5 minutes.
3. Wipe the cook surface using a wet towel, dampened with a small amount of water and a mild dish detergent. Then
rinse with a towel dampened with clean water 3-4 times. Wipe the surface down with a dry towel and the Plancha
is ready for service.
CAUTION: THE COOKING SURFACE WILL BE HOT!
USE CAUTION WHEN WIPING SURFACE,
PAYING PARTICULAR ATTENTION TO AVOID STEAM FROM DAMP TOWELS.

DAILY USE & MAINTENANCE
DAILY USE AND MAINTENANCE
1. Check and empty the grease/debris tray frequently throughout the day. Keep the drain clear and do not allow the
tray to overflow.
2. The cooking surface should be scraped periodically throughout the day. To remove loose debris use a dry towel.
CAUTION: COOK SURFACE IS VERY HOT!
3. End of the day: The Plancha cook surface should be cleaned thoroughly at the end of each day. Wood Stone
recommends the 3M 710 Scotch Brite Quick Clean Griddle Cleaning System for cleaning the Plancha cooking
surface. This kit includes all of the necessary tools to clean the Plancha surface properly including Scotch Brite
Quick Clean Griddle Liquid. These products are available through your dealer or restaurant supplier.
When using chemicals to clean the grill surface, first shut down the Plancha and allow it to cool for 30 minutes. If
the Plancha is too hot, the chemical may tend to boil or burn off immediately and not work as effectively. Do not
pour water onto a hot Plancha to cool it as this can warp the cook surface. DO NOT USE EXCESSIVE AMOUNTS
OF WATER TO CLEAN THE PLANCHA.
Be careful when using scrapers on the cook surface to avoid scratching or gouging the top. Be aware that
the cook surface is made of mild steel—it will not clean to a shiny silver-like surface. Do not use heavy duty
degreasers or oven cleaners on the Plancha as these are not generally intended for use on hot surfaces.
Damage caused by using spray hoses or excessive water, and scratching or marring of the cook surface, is not
covered by the warranty.
4. The front, sides and back may be wiped down with a cloth and mild detergent if needed. Do not use abrasive
cleaners or scouring pads as these will scratch the stainless steel.
5. The Plancha grill is capable of extremely high temperatures, much higher than a conventional electric grill. To
ensure the reliability of the electrical components, cooling vents are provided on the appliance—on the sides,
back and underneath of the appliance. These vents must not be blocked, and must be kept clean and free of
grease and dust.

measurements.
If Plancha is heated up / in use: Allow 30 minutes of inactivity to
stabilize after last cooking run. Make certain grill surface is clean.
2. Take four temperature measurements using a surface probe. Note
measurement once reading has stabilized. Measurement points are
shown on the diagram at left—one at the center of each zone.
3. Temperature reading at each point should be within the range
495–525 °F.
