D. Assemble the stacking pipes provided in the stacking
kit as shown in the diagram at the top of this page. This
allows both ovens to be supplied by a single gas line. The
minimum recommended size of a single supply line for
two stacked ovens is 1 inch. Use a pipe thread compound
that is intended for use on propane gas piping and be sure
to check for leaks before nalizing the installation.
E. Check leveling of unit four (4) ways (using a common
carpenter's level on the rack inside the oven).
F. Plug the cord set of each unit into a 115-Volt power supply
outlet.
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.

POWER FAILURE
In the event of a power failure, no attempt
should be made to operate this oven.
IMPORTANT
All gas burners and pilots need sufficient
air to operate and large objects should not
be placed in front of this oven, which would
obstruct the airflow through the front.
Objects should not be placed on main top rear
of oven while in use. This could obstruct the
venting system of the unit's flue products.
Gas Connection
The 1" NPT inlet at the rear must be considered in piping the
gas supply for double stack units or 3/4" NPT for individual (or
single deck) connections. Undersized gas supply line(s) may
restrict the gas supply and aect 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.
Recommended supply pressures are 7" WC, (NAT), and
11" WC, (PRO); ± 5%. (Must not exceed 13.8" WC [NAT], and
15" WC [PRO]).
Electrical Connection
A 15 AMP service must be provided for each oven. For 115
VAC usage, a cord and plug (NEMA #5-15P) is provided but
connection to the electrical service must be electrically
grounded in accordance with local codes, or in the absence of
local codes, with the National Electrical Code, ANSI/NFPA 70,
or the Canadian Electrical Code, CSA C22.2, as applicable.
This appliance is equipped with a three-prong (grounding)
plug for your protection against shock hazard and should
be plugged directly into a properly grounded three-prong
receptacle.
DO NOT CUT OR REMOVE THE
GROUNDING PRONG FROM THIS PLUG.
A wire diagram is axed to the rear of the unit.
Ventilation & Air Supply
Proper ventilation is highly important for good operation.
There are only two choices for properly venting an oven: 1)
canopy hood style or 2) direct venting. The ideal method
of venting a GAS Convection Oven is through the use of a
properly designed canopy, which should extend 6" (150 mm),
beyond all sides of the appliance and 6'6" (1950 mm) from the
oor.
