INSTALLATION CONT’D
NOTICE
Always ensure the grease filters supplied with the oven are
used. Replacement filters may be obtained from a Lang
representative.
NOTICE
No other exhaust systems may be connected to this system. Do
not try to vent or exhaust another appliance into this hood.
Installing the Hood
Remove the hood from the hood crate. Place the body of the hood on the floor with the open side down.
Use cardboard or other protective material to avoid scratches.
Remove all protective vinyl coatings and place the hood side support trim on each side of the hood and
screw to the front of the hood with (4) #1/4-20 stainless steel truss head machine screws and spacer
bushings. Install (4) #10-32 truss head stainless steel machine screws through the side support trim and
into the top of the hood.
Attach the rear trim to the opposite end of the hood side support trim using (4) #10-32 truss head stainless
steel machine screws.
Place the combustion exhaust duct (shipped strapped to the oven skid) on the top of the heat exchanger
exhaust opening.
Lift the hood and trim assembly and place it over the top of the oven so that the side and rear trim rest on
the top of the oven.
Push the hood assembly toward the rear of the oven and align the vent exhaust opening and the exhaust
duct opening with the associated ducts on the oven.
Attach the hood side support trim and the rear trim to the top of the oven with #10-32 stainless steel truss
head machine screws.
Attach the hood to the exhaust and vent ducts using #10 stainless steel sheet metal screws.
Install the hood airflow sensor tube at the hood collar opening and at the airflow switch at the junction
box located at the top of the oven. Double-check this connection for leaks or crimps in the tube or hose.
Install the hood deflector using #10-32 stainless steel round head machine screws at the back of the
deflector and #10-32 stainless steel truss head machine screws at three holes at the front edge of the
deflector.
Place the three hood filters and the filler channel in the hood filter holder and onto the front lip of the
hood.
Place the hood grease cup on the rear lip of the hood at the drain opening.
Connecting Utilities
Connect the electrical service connection to the oven. Consult the data plate for specific current and
voltage ratings. Wire in compliance with local requirements and the National Electric Code.
Connect water supply to the oven at the water solenoid valve at the top left corner of the oven. Water
supply must be between 20 and 80 psi at all times with a water flow of 5 gallons per minute. Provide a
water shut-off valve near the oven for servicing.
Connect the drain to the oven. Water drained from the oven will reach temperatures near boiling. The
drain line must be provided with an air gap to prevent back siphoning.
