INSTALLATION INSTRUCTIONS
WARNING
TO REDUCE THE RISK OF FIRE, THE APPLIANCE IS TO BE
MOUNTED ON FLOORS OF NON-COMBUSTIBLE
CONSTRUCTION. SUCH CONSTRUCTION SHALL EXTEND A
MINIMUM OF 12-INCHES BEYOND THE EQUIPMENT ON ALL
SIDES.
Receiving the Oven
Upon receipt, check for freight damage, both visible and concealed. Visible damage should be noted on
the freight bill at the time of delivery and signed by the carrier's agent. Concealed loss or damage means
loss or damage, which does not become apparent until the merchandise has been unpacked. If concealed
loss or damage is discovered upon unpacking, make a written request for inspection by the carrier's agent
within 15 days of delivery. All packing material should be kept for inspection.
Do not return damaged
merchandise to Lang Manufacturing Company. File your claim with the carrier.
Pre-Installation
Check the area where the oven is to be installed for the following:
•
No electrical conduit or wires are to be under the floor of the oven.
•
The oven must be mounted on a non-combustible surface. This includes the structure beneath the
floor.
•
Ceiling height above the oven should be sufficient to allow servicing the lifter, vent and blower
motor assemblies. The maximum height needed for tilting the oven up is 105 inches.
•
Clear access is needed to the roof or exterior of the facility for hood exhaust. Check local codes for
correct venting.
•
Access is needed for an air-gap drain in the rear left corner of the oven.
•
Adequate space is needed in front of the oven to load and unload racks. Racks are hot and need
space to cool.
•
The hood exhaust will need at least 600 CFM of make-up air.
•
Local and national codes will require an electrical shut-off within a reasonable distance to the oven.
•
Local and National codes will require access to a manual Gas Shut-off.
•
The door swing will need to be clear to allow adequate loading and unloading of the oven. Check
the space next to the oven and be sure it does not interfere with the door.
Un-Crating
The oven is shipped in one piece. (It can be uncrated and split into two for easy installation where door
openings are limited to 36 inches.)
Move the large oven crate into the room, near where it is to be installed. Allow clear access for a forklift
or lifting apparatus at the top end of the oven. The bottom end of the oven crate is beveled at the skids.
Check the crate for damage that may have occurred in shipping.
Remove crating materials and plastic wrap from the oven. Remove the heat exchanger vent duct from the
skid.
CAUTION
THIS APPLIANCE, WHEN INSTALLED, MUST BE ELECTRICALLY
GROUNDED IN ACCORDANCE WITH LOCAL CODES, OR IN THE
ABSENCE OF LOCAL CODES, WITH THE NATIONAL
ELECTRICAL CODE, ANSI/NFPA 70-1996.
