Location
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.
IMPORTANT: All gas burners and pilots need su cient air
to operate and large objects should not be placed in front
of this oven, which would obstruct the air ow 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

Before assembly and connection, check gas supply.
A. The type of gas for which the unit is equipped is stamped
on the data plate located on the lower rear of the left side
panel. Connect a unit stamped “NAT” only to natural gas;
connect a unit stamped “PRO” only to propane gas.
B. If it is a new installation, have gas authorities check meter
size and piping to assure that the unit is supplied with
su cient amount of gas pressure required to operate the
unit.
C. If it is additional or replacement equipment, have gas
authorities check pressure to make certain that existing
meter and piping will supply fuel at the unit with not
more than 1/2” water column pressure drop.
NOTE: When checking pressure be sure that all other
equipment on the same gas line is on. An internal pressure
regulator is supplied with Sun re Convection Ovens.
Regulator is preset to deliver gas at pressure shown on the
rating plate.
The appliance and its individual shut-o valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/2 PSI (3.45kPa.).
The appliance must be isolated from the gas supply piping
system by closing its individual manual shut-o valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 PSI (3.45 kPa).
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.
CAUTION: Disconnect Both Units from Electrical Supply
Before Servicing.
Gas Supply
The importance of the proper installation of commercial
Gas cooking Equipment cannot be over stressed. Proper
performance of the equipment is dependent, in great part,
on the compliance of the installation with the manufacturer’s
speci cations. Installation must conform to local codes or, in
the absence of local codes, with the National Fuel code, ANSI
Z223.1, Natural Gas Installation code, CAN/CGA-B149.1 or the
Propane Installation Code, CAN/CGA-B149.2, as applicable.
NOTE: Adequate clearance must be provided for servicing
and proper operation.
Gas Connections
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 a ect 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]).
Part Number 4530588 rev 3 4/158
INSTALLATION Continued
Electrical Connections
Electrical Grounding Instructions:
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 properly grounded three-prong
receptacle. DO NOT CUT OR REMOVE THE GROUNDING
PRONG FROM THIS PLUG.
A wire diagram is a xed to the rear of the unit.
Power Failure
In the event of a power failure, no attempt should be made
to operate this oven.
Ventilation and Air Supply
When the installation of a canopy type exhaust hood is
impossible the oven may be direct vented. Before direct
venting check your local codes on ventilation, in the absence
of local codes, refer to the National Fuel Code NFPA 54, ANSI
Z223.1 (latest revision).
DRAFT DIVERTER
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” (152 mm),
beyond all sides of the appliance and 6’6” (1981 mm) from
the oor.
A strong exhaust fan will create a vacuum in the room. For an
exhaust system vent to work properly, exhaust and make-up
air must be balanced properly. For proper air balance contact
your local H.V.A.C. contractor.
All gas burners and pilots need su cient air to operate and
large objects should not be placed in front of this oven,
which would obstruct the air ow through the front.
Installation of Direct Flue
If the unit is to be connected to a direct ue, it is necessary
that draft diverter be installed to insure proper ventilation.
Direct venting, should be positioned on the main top and
fastened with sheet metal screws provided.
DO NOT UNDER SIZE VENT PIPE! This can cause resistance
to ow and impede good venting. We suggest that if a
horizontal run must be used it should rise not less than 1/4”
(6.25mm) for each linear foot of run, and after a total of 180°
of bends you should increase the size of stove pipe by two
(2”) inches. The ue should rise 2’ (60cm) to 3’ (91cm) above
the roof line or 2’ (60mm) to 3’ (91cm) above any portion of a
building within a horizontal distance of 10 (3 meters) feet.

Adjustments
NOTE: Each oven has been factory tested and adjusted prior
to shipment. It may be necessary to further adjust the oven
as part of a proper installation. Such adjustments are the
responsibility of the installer. Adjustments are not considered
defects in material and workmanship, and they are not
covered under the original equipment warranty.
Lighting
1. Turn on main gas valve. Remove the lower front
cover and the service panel above the control panel.
Drop the control panel and leak test all ttings and
connections upstream from the service valve located on
the redundant combination gas valve. Should any gas
leaks be detected, turn OFF main gas valve, correct the
problem and retest.
2. Open shuto valve located on the redundant
combination gas valve. Activate control panel and set to
desired temperature. The burners are ignited by direct
spark, check all ttings again and correct any leaks and
recheck.
Replace all service panels and covers before operation.
NOTE: All electronic ignition systems are supplied with a
redundant gas valve. Therefore, the unit is not supplied with
an external pressure regulator.
NOTE: During installation there will be air in the gas line. This
air will have to bleed o before ignition can be established.
The electronic ignition system has a ninety second lock-out
as a safety device on all units. Therefore, several attempts
may be required before pilot ignition is established, wait ve
minutes after each attempt.
FOR YOUR SAFETY: KEEP YOUR APPLIANCE ARE FREE FROM
COMBUSTIBLES.
To Conserve Energy
Do not waste energy by leaving controls at high temperature
settings during idle periods. Lower settings will keep oven
warm and ready for next use period.
