Assembly; Double Deck Units - Garland MASTER Installation And Operation Manual

INSTALLATION Continued

Assembly

All units are equipped with N.S.F. approved legs. These
legs must be installed to provide a minimum 6" (153mm)
clearance between the floor and the bottom of the unit in
order to meet national Sanitation Foundation requirements.
A. To install the legs, raise the front of the unit and block
it. Insert the two front legs into the conical leg retainers.
Repeat at the rear.
B. Level the unit by placing a carpenter's-type level on one
of the oven racks, and adjust each leg by turning its "foot"
to raise or lower the height of the leg. The bottom of each
"foot" is hexagonal in shape so that a wrench may be
used.

Double Deck Units

A. Install legs as above to the bottom unit.
B. Remove the combustion chamber from the top unit and
raise it into place. Align the body sides and backs of the
two units.
C. Using the angle bracket provided, fasten the bottom
front of the top unit to the main top of the bottom unit,
near the center, as shown.
