COMBI OVEN INSTALLATION MANUAL
HEALTH AND SANITATION PRACTICES
BKI Combi Ovens are manufactured to comply with
health regulations and are tested and certified to
UL®, cUL®, and NSF® standards. You must operate
the equipment properly using only quality products
and use meat thermometers to insure meats are
thoroughly cooked.
Food Handling
• Wash hands thoroughly in warm, soapy water after
handling raw poultry or meats.
• Clean and sanitize all utensils and surfaces that
have been in contact with raw products. Clean
and sanitize the meat forks or baskets between
cooking.
• Never place cooked meats on the same surfaces
used to prepare raw meats, unless the area has
been thoroughly cleaned and sanitized.
Storage of Raw Meats
• Designate an area or shelf strictly for the storage
of all raw meats to be used in the oven.
• Raw product must always be stored at
temperatures below 38° F. (3° C.).
Coding Cooked Foods
• All products cooked during the day should be sold
the same day.
NOTE: Follow your company’s procedures for the
handling of any leftover product.
Storage of Prepared Foods
• Cold foods should be kept at or below
38° F. (3° C.).
• Hot foods must be maintained to meet local
health codes, usually a minimum 145° F (63°).
• Never store or mix raw foods above cooked foods,
as this is a health hazard. The drippings from raw
foods contaminate cooked or processed foods.
• All chicken and chicken parts to be stored
overnight must be thoroughly iced down
and refrigerated.
The following points are a listing of requirements that should be verified prior to the installation of the BKI
Combi Oven. For more specific installation requirements, refer to instruction manual that comes with the
oven.
1. Verify ventilation requirements. Will the installation use an existing hood or ventless hood?
2.Verify ventilation height requirements. What is the clearance under the hood?
3. If a ventilation hood is installed above the oven, it should project 19.69” (500 mm) over the front of the
oven. The suction eect should be 400 to 800 m3/h (523 to 1046 yd3/h).
4. Verify the drain is accessible and will not be located directly under the oven.
5. Verify the drain for the oven is made of stainless steel or an equally temperature-resistant material,
minimum 175° F.
6. Verify the drain for the oven is at least 1.97” (50 mm) in diameter and a fall of at least 3° or 5%.
7. Verify correct power supply (1 Phase, 3 wire, 120V, Amperage) is available and within 10 feet of oven
location. Power cord exits oven on right hand side (facing the unit).
8. Verify proper Electrical Supply Voltage, Amperage, and Phase. Typical requirements are 120VAC, 3 Phase,
60 Hz with 3 wires (2 legs with a ground).
NOTE: There is no NEUTRAL.
9. Verify gas supply pressure and volume capacity.
10. Verify the installation area for the oven will have minimum clearances of 3” (75 mm) from the rear wall,
0” from any objects on the right side of the oven and 0” for clearance on the left side of the oven while
in operation. The left side requires 20” (508 mm) clearance for servicing (page 23).
NOTE: High heat source equipment should not be located to the left of the oven.
11. Verify cold water supply to the oven will be between 40-60 PSI (flowing).
NOTE: If water hardness exceeds the allowable limit noted, an approved water treatment system capable
of removing Chlorine and Chloramines should be installed in the water supply line to the oven. Installing
a water treatment system will extend the life the oven and minimize the potential for future corrosion.
Potential Install Location: _______________________________ Store Number: ____________________________
Gas combi ovens must be located under an
exhaust hood. Information on the construction and
installation of ventilating hoods may be obtained
from Vapor Removal from Cooking Equipment,
NFPA Standard No. 96 (latest edition).
• Kitchen ventilation must include a provision for
an adequate flow of fresh air for gas combustion
and to prevent a negative-pressure condition. The
bottom of the oven provides air supply access
for gas combustion and must be kept clear at all
times. DO NOT obstruct or restrict ventilation nor
the air flow required to support combustion.
• DO NOT obstruct the flow of the exhaust flue at
the top rear of the oven. It is especially critical that
gas supply piping and electrical support cord and/
or receptacle be routed away from the path of the
hot combustion fumes.
Exhaust Hood
NOTE: all hood and ducting of ovens must comply
to local codes interpreted by fire and building
inspectors in the municipality where the oven is
installed.
Ventilation hoods must ensure an adequate amount
of incoming air during operation and must be
operated whenever the Combination oven/steamer
is used in order to avoid the accumulation of
condensation in the hood area.
FAILURE TO VENT THIS APPLIANCE PROPERLY
MAY BE HAZARDOUS TO THE HEALTH
OF THE OPERATOR. Equipment damage,
operational problems, and unsatisfactory baking
performance may also be the consequence of
improper venting. Any damages sustained by a
failure to properly vent this oven are not
covered under warranty.

WATER QUALITY
COMBI OVEN INSTALLATION MANUAL
As with all steam related products, water filtration
and regular filter replacements may be necessary
with the Combi. It is strongly recommended to have
a water analysis performed prior to installing the
Combi. Poor water quality can have a big impact
on cook quality, performance, and longevity of
the Combi. Varying combinations of pH; alkalinity;
hardness; chlorides; total dissolved solids; and other
chemical characteristics, when subjected to high
temperatures, will cause water to have a tendency
to either scale or corrode.
There are a number of dierent water filter/
treatment systems available and each has its own
benefits and specialties. Below are a dierent styles
and their benefits. Multiple styles may need to be
used to get the water to proper levels.
• Particle Filter
When the water contains sand, iron particles, or
suspended matter, we recommend a 5-15 µm
(micrometer) particle filter.
• Active Carbon Filter
When the level of chlorine (Cl) in the water
exceeds 0.5 mg/L (ppm) (information available
from the water company), an active carbon filter
should be installed.
• Phosphate Additive System
A Phosphate Additive (Feeder) System is
recommended for steam generator units
only when a moderate level of scale (not
containing chloride) is experienced. The system
recommended is Kleensteam from Everupure.
• Ion Exchange System
An ion exchange system is recommended for a
steam generator based unit when a high level of
scale (not containing chloride) is experienced and
for a spritzer based unit when any scale (not
containing chloride) is experienced. Systems
recommended: Claris from Everpure (H+ Ion
Exchanger). Sodium ion exchangers (as used in
dishwashers) must not be used.
• Blended Reverse Osmosis (RO)
When the water has a chloride (Cl) concentration
above 20 mg/L (= 20 ppm), a blended RO system
should be installed to avoid corrosion.
NOTE: Make sure a minimum conductivity of 20
µS/cm (microSiemens) remains in the water for
steam generator units.
Water quality must conform to the below
requirements. If water does not meet the minimum
quality and damage to the oven is determined to
be due to water quality, it will be considered nonwarranty and will not be covered under the stated
warranty policy.
BKI Minimum Water Quality Requirements
– Hardness (CaCO3) = Less than
7.5 GPG (Grains per Gallon)
– TDS (Total Dissolved Solids) = Less than
100.0 mg/L (Milligrams per Liter)
– Free Chlorine = Less than 0.5 mg/L
(Milligrams per Liter)
– Chlorides = Less than 20 mg/L
(Milligrams per Liter)
– Chloramines = Less than 0.5 mg/L
(Milligrams per Liter)
– Total Alkalinity = Less than 20 mg/L
(Milligrams per Liter)
– Total Silica = Less than 10 mg/L
(Milligrams per Liter)
–pH level = 7.0 to 8.0
– Conductivity (Boiler Models only) = Minimum
of 20 µS/cm (microSiemens per cm)
Water Usage
Average Water Flow = 8.5 gal/hour at 36 psi inlet
pressure for half size 6 grid oven; 9.8 gal/hour at
36 psi inlet pressure for half size 10 grid oven; 11.6
gal/hour at 36 psi inlet pressure for full size 10 grid
oven; Peak Water consumption = 2.6 gal/min
