Double-Deck 12" (305 mm)

NOTE: Install units with casters in very tight locations for ease of service.

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 unit’s  ue products.

A. Position insert in bottom leg opening and tap insert up

into leg until it seats at collar. Attach six inch (6”, 152mm) 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).

C. Install the interconnecting  ue parts, carefully following

the instructions contained in the stacking kit. Pay particular attention to the type of ovens you are stacking and be sure to follow the corresponding instructions.

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.
