Product Features
Antispark and Antiparticulate Design
The exhaust system is specially designed to reduce the discharge of
sparks and airborne particles.
As exhaust gases pass through the vent system, airow is redirected
to lower the velocity and temperature of sparks and particulates be-
fore they exit the unit. This design helps improve operational safety
and reduces the risk of sparks escaping into the surrounding envi-
ronment.
Oxygen Intake Control
The lower air vent provides precise control of airow into the com-
bustion chamber.
Its slide-adjustable design allows the vent opening to be easily
increased or decreased with a single movement, enabling accu-
rate regulation of combustion air. The vent also incorporates a
locking mechanism to help maintain the selected setting during
operation.
Spark Arrestor Cap
The spark arrestor cap helps reduce the discharge of sparks and
airborne particulate matter from the exhaust system.
Its design helps cool exhaust gases before they exit the unit,
reducing the temperature of combustion byproducts and helping
protect exhaust hood lters from excessive heat buildup and dis-
coloration.
Upper Vent
The upper vent provides adjustable exhaust control with ve vent
positions, allowing airow and smoke discharge to be regulated ac-
cording to operating conditions.
By adjusting the vent opening, users can optimize combustion per-
formance, temperature control, and exhaust ow throughout the
cooking process.
For additional operating instructions, refer to the Operating Instruc-
tions.

2. Fully open the lower air intake vent by opening the ash drawer.
3. Place re starters or ignition cubes in three evenly spaced locations within the charcoal pile.
4. Ignite the re starters and close the oven door.
5. Allow the charcoal to ignite and burn for approximately 25–40 minutes, depending on the oven
model and charcoal type.
6. Once the charcoal is burning evenly, close the lower air intake vent and allow the oven to stabi-
lize for an additional 10 minutes while keeping the upper exhaust vent open.
7. Verify that the charcoal is fully ignited with no visible black or unlit charcoal remaining.
Model Recommended Charcoal Load
KM-CHO28 Series 13.2 lb
KM-CHO35 Series 22 lb
The oven is ready for operation when the charcoal bed is evenly lit and the desired cooking tem-
perature has been reached.
16
Ready to Cook
Once the charcoal has fully ignited and the
oven has reached the desired cooking tempera-
ture, adjust the cooking rack position according
to the type and thickness of the food being
prepared.
Position the cooking rack closer to the char-
coal for higher heat and faster cooking.
Position the cooking rack farther from the
charcoal for lower heat and more controlled
cooking.
Increasing Smoke Flavor
For foods that benet from additional smoke
avor, the upper exhaust vent may be partially
closed to increase smoke retention. Do not
completely close the vent while charcoal is
actively burning.
Note: Reducing airow will increase smoke
retention inside the cooking chamber and may
intensify the smoky avor of the food.
Adjusting the Cooking Rack
Open the oven door carefully.
Remove or reposition the cooking rack to the
desired height.
Ensure the rack is securely seated before load-
ing food.
Preparing for Cooking
Before placing food in the oven:
Open the upper and lower vents to establish
proper airow.

oven door.
Important: Always use heat-resistant gloves
when handling cooking racks or adjusting
components while the oven is hot. All interior
surfaces may reach high temperatures during
operation.
Shutting Down the Oven
At the end of service, close the upper exhaust vent and ensure the lower air intake vent is fully
closed.
Closing both vents restricts airow to the charcoal bed, allowing the remaining charcoal to extin-
guish naturally while preserving any unused fuel for future use.
Important
Do not extinguish the charcoal with water or any other liquid. Rapid cooling may damage oven
components and can create steam and ash hazards.
Allow the charcoal to burn out naturally by keeping both vents closed.
Any remaining charcoal may be reused during the next cooking session, provided it is dry and in
good condition.
CAUTION: Charcoal and ash may remain hot for several hours after operation. Allow the oven to
cool completely before handling charcoal, removing ash, or performing cleaning and maintenance
procedures.
17
Monitoring Charcoal Levels
