DELIVERY AND LOCATION
DELIVERY AND INSPECTION
All Blodgett ovens are shipped in containers to prevent damage. Upon delivery of your new oven:
• Inspect the shipping container for external damage. Any evidence of damage should be noted on the delivery receipt
which must be signed by the driver.
• Uncrate the oven and check for internal damage. Carriers will accept claims for concealed damage if notied within
fteen days of delivery and the shipping container is retained for inspection.
The Blodgett Oven Company cannot assume responsibility for loss or damage suffered in transit. The carrier assumed full
responsibility for delivery in good order when the shipment was accepted. We are, however, prepared to assist you if ling
a claim is necessary.
OVEN LOCATION
The well planned and proper placement of your oven will result in long term operator convenience and satisfactory perfor-
mance. The following clearances must be maintained between the oven and any combustible or non-combustible construc-
tion.

ing in damage to the oven.
Before making any utility connections to this oven, check the rating plate to be sure the oven specications are compatible
with the electrical services supplied for the oven.

ELECTRIC CONVECTION OVENS 9 INSTALLATION
INITIAL STARTUP
ADJUSTMENTS ASSOCIATED WITH INITIAL INSTALLATION
Each oven, and its component parts, have been thoroughly tested and inspected prior to shipment. However, it is often
necessary to further test or adjust the oven as part of a normal and proper installation. These adjustments are the respon-
sibility of the installer, or dealer. Since these adjustments are not considered defects in material or workmanship, they are
not covered by the Original Equipment Warranty. They include, but are not limited to:
• calibration of the thermostat
• adjustment of the doors
• leveling
• tightening of fasteners.
No installation should be considered complete without proper inspection, and if necessary, adjustment by qualied installa-
tion or service personnel.
