into leg till it seats at collar. Attach six inch (6") legs to
lower oven section. Raise unit or lay on its left side. Place
the front legs on the oven so as to line up with four (4)
attaching bolt holes. Secure leg to oven frame using (4)
3/8-16 x 3/4 bolts and washers provided. Repeat at rear of
unit.
B. Remove lower front cover of top deck (located under oven
doors). Raise top deck into place and line up body sides
and back of the unit. Fasten the rear of the units together,
with the stacking bracket using (6) 1/4-20 machine screws,
lock washers and nuts, (provided).

F. Wire each unit to a 230-Volt power supply.
G. Maintain clearance from combustibles.
Each gas appliance shall be located with respect to building
construction and other equipment so as to permit access to
the appliance. Such access and clearance may be necessary
for servicing and cleaning.

Gas Connection

The 1" BSPT inlet at the rear must be considered in piping the
gas supply for double stack units or 3/4" BSPT for individual
(or single deck) connections. Undersized gas supply line(s)
may restrict the gas supply and affect performance. If other
gas appliances are supplied by the same supply line, the
supply line must be sized to carry the combined volume
without causing more than 1/2" pressure drop at the manifold
of each appliance on the line at full rate.
