* Electric connection wiring is sized for 90ºC copper wire at 125% of rated input.
NOTE: Double units can have phase loads partially equalized by matching lines during hook-up. Otherwise, CTB-Double
or CTBR-Double load ratings are twice the above data.
Cooking in a convection oven differs from cooking in a
conventional deck or range oven since heated air is con-
stantly recirculated over the product by a fan in an en-
closed chamber. The moving air continually strips away
the layer of cool air surrounding the product, quickly al-
lowing the heat to penetrate. The result is a high qual-
ity product, cooked at a lower temperature in a shorter
amount of time.
Blodgett convection ovens represent the latest advance-
ment in energy efciency, reliability, and ease of opera-
tion. Heat normally lost, is recirculated within the cooking
chamber before being vented from the oven: resulting in
substantial reductions in energy consumption and en-
hanced oven performance.

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 ship-
ping container is retained for inspection.
The Blodgett Oven Company cannot assume responsibil-
ity for loss or damage suffered in transit. The carrier as-
sumed 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
performance.
The following clearances must be maintained between
the oven and any combustible or non-combustible con-
struction.
CTB
• Oven body left side - 0” (0cm)
• Oven body back - 0” (0cm)
CTBR
• Oven body right side - 0” (0cm)
• Oven body back - 0” (0cm)
It is essential that an adequate air supply to the oven be
maintained to provide a sufcient ow of combustion and
ventilation air.
• Area must be accessible for proper servicing.
• Keep the oven area free and clear of all combus-
tibles such as paper, cardboard, and ammable
liquids and solvents.
• To ensure proper operation, ventilation must not be
obstructed in any way. Tripping of the blower motor
thermal overload protective device is caused by ex-
cessive ambient temperature on the control side of
the oven resulting from insufcient ventilation. This
condition must be corrected immediately to avoid
permanent 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.
1. The rating plate is attached to the underside of the
oven upper ledge above the control panel.

oughly 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 adjust-
ments are the responsibility 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 installation or service personnel.
