SECTION 2 INSTALLATION II. INSTALLATION, PREPARATION, AND SUPPLY When preparing the oven for installation at a location, the latest International, National or Local Requirements should be adhered to. The ovens must be installed on an even (level) non-flammable flooring and any adjacent walls must be non-flammable. The minimum allowed distance from the rear of the oven to the wall is 12 (30cm). The ovens can be supported only by legs. No casters are allowed.
SECTION 2 INSTALLATION III. VENTILATION SYSTEM IMPORTANT Where international, national, or local codes require the installation of fire suppression equipment or other supplementary equipment, DO NOT mount the equipment directly to the oven. MOUNTING SUCH EQUIPMENT ON THE OVEN MAY: VOID AGENCY CERTIFICATIONS RESTRICT SERVICE ACCESS LEAD TO INCREASED SERVICE EXPENSES FOR THE OWNER REQUIREMENTS A mechanically driven ventilation system is required for the oven.

IV. SECTION 2 INSTALLATION THERMOCOUPLE INSTALLATION 1. Install the thermocouple sensing bulb into the correct hole in rear of bake chamber as shown in Figure 2-11. 2. Thread thermocouple lead through grommet and into the machinery compartment. Figure 2-11 Thermocouple Installation Locations 3. Remove the right-side access panel of the machinery compartment.
SECTION 2 INSTALLATION 4. Connect the thermocouple leads to the temperature controller as shown in Figure 2-13. 5. Repeat Steps 1-4 for each of the other ovens in the installation.
SECTION 2 INSTALLATION V. ASSEMBLY If the installation includes upper ovens mounted atop lower ovens, the ovens must be stacked before joining the tandem ovens together. If the installation includes ovens that are to be mounted on stands, assemble the ovens to the stands before joining the ovens together. An exploded view of the stand is shown in Figure 2-14.
SECTION 2 INSTALLATION JOINING THE OVEN BODIES For TANDEM and DOUBLE TANDEM installations, perform Steps 1-7 to join the ovens. For TRI TANDEM installations, perform Steps 1-7 to join two of the ovens together, and ensure that they are level; then, repeat Steps 1-7 to join the third oven to the two that are assembled. For QUAD TANDEM installations, perform Steps 1-7 for EACH PAIR of ovens, producing two sets of two joined ovens. Do not assemble the center bridge section at this time. 1.
SECTION 2 INSTALLATION 3. Insert three of the supplied 1/2 x 5 bolts through the holes in the frame of the right oven, pointing outward as shown in Figure 2-17. Then, slide the spacers into place on the bolts. 2-1/2 x 2-1/2 ( 64 x 64mm) spacers Bolts 2-1/2 x 8 (64 x 203mm) spacers Figure 2-17 Bolts and Spacers 4. Push the ovens together. Check that the mounting bolts, alignment plate, and sealing gasket are properly aligned.
SECTION 2 INSTALLATION 5. Check the alignment of the track rails using a straightedge. The rails MUST BE LEVEL across the gap between the ovens. If necessary, adjust the oven legs to align the track rails. Figure 2-19 Checking Track Rail Alignment 6. Tighten all of the attaching bolts. Check that the mating edges of the ovens align properly. If gaps appear between the tops of the ovens, it will be necessary to loosen the connecting bolts and realign the ovens.
SECTION 2 INSTALLATION 9. Test-fit the transition section of the conveyor frame, as shown in Figure 2-21. The alignment pins on the bottom of the frame ensure correct spacing of the center ovens. Figure 2-21 Transition Frame Placement 10. Attach the two angled support brackets between the two center ovens, as shown in Figures 2-22a and 2-22b.
SECTION 2 INSTALLATION 10. Remove the transition section of the conveyor frame. Place the transition floor panel into place atop the support brackets. See Figure 2-23. Figure 2-23 Installing the Transition Floor Panel 11. Replace the transition (center) conveyor section, as shown in Figure 2-24.
INSTALLING THE CONVEYOR FRAME AND BELT FOR ALL TYPES OF OVENS, ENSURE THAT THE DRIVE SECTION/END OF THE CONVEYOR FRAME IS PLACED ON THE SAME END OF THE OVEN AS THE CONVEYOR DRIVE MOTOR. 1. For a TANDEM or DOUBLE TANDEM oven, slide the conveyor frame assembly into either end of the oven.
SECTION 2 INSTALLATION 2. Slide the conveyor belt through the support rods underneath the frame, and thread it through the oven. Then, reach through the oven window and pull the free end of the belt through the oven so that it lies atop the conveyor frame. Direction of travel Check that the links on the conveyor are oriented as shown in Figure 2-26. 3. Connect the inside master links. Check that the links are oriented as shown in Figure 2-27.
5. 6. Slide the top transition panel into place. Then, slide the two transition side panels into place. See Figure 2-29. 7. If the four latches are not already attached to the side and top transition panels, attach them in place as shown in Figure 2-29. For a TANDEM, DOUBLE TANDEM, or TRI TANDEM oven installation, skip ahead to the next section. For a QUAD TANDEM oven installation, continue on to Step 6.
SECTION 2 INSTALLATION GAS OVEN ROUGH-IN UTILITY ROUGH-IN DIMENSIONS AND POSITIONING CAUTION IT IS REQUIRED THAT THE OVEN BE PLACED UNDER A VENTILATION HOOD FOR ADEQUATE AIR SUPPLY AND VENTILATION. GAS SUPPLY & ELECTRICAL SUPPLY 5 PROVIDED BY CUSTOMER 2 To en v DO NOT USE CONDUIT FOR GROUND O 1 CIRCUIT BREAKER 1 circuit breaker/fused disconnect switch with lockout/tagout is required for each oven cavity. Wire each oven cavity separately.
SECTION 2 INSTALLATION VI. ELECTRICAL CONNECTION Check the oven data plate before making any electric supply connections. Electric supply connections must agree with data on the oven data plate. A typical oven data plate is shown in Figure 2-34 (on Page 2-24). NOTE: When the oven is installed, it must be electrically grounded in accordance with current IEC/CEE requirements and also with local codes.
SECTION 2 INSTALLATION Figure 2-34 Typical Oven Data Plate - Models PS360/PS360WB 2-24
VII. GAS SUPPLY FOR GAS HEATED OVENS Pipe sizing -- Always install a shut off valve in the gas supply line to the oven. This valve should be the same size as the supply line. Please remember that the longer the pipe runs, the more the pressure drops. One 90° elbow equals a 1,2 m length of pipe.
SECTION 2 INSTALLATION VIII. PREPARATION FOR VARIOUS GASES Before proceeding to set up the oven for a specific gas, the main gas supply valve and the electrical supply circuit breaker should be turned off. When preparing the oven for use of Group H or L Natural gases, the orifice (Manifold) pressure should be adjusted to the values shown in the chart on Page 1-1.

SECTION 2 INSTALLATION IX. CHANGING ORIFICES TO CHANGE MAIN ORIFICE (Refer to Figure 2-36) 1. Turn off main gas supply valve. 2. Open 3/4" union in gas supply line. 3. Remove 1/2" nuts securing gas train to the burner housing. 4. Using a 11/16" wrench remove orifice from the mounting flange. 5. Install new orifice in reverse order. WARNING Before operating oven check for gas leaks! TO CHANGE BYPASS (LOW FLAME) ORIFICE (Refer to Figure 2-36) 1. Turn off main gas supply valve. 2.
4. Replace cover screw on adjustment valve and turn off main gas supply valve. 5. Record the reading obtained from the gas meter and calculate obtained gas flow. Compare this to the indicated flow in the CHART OF ORIFICE SIZES, GAS PRESSURES, NOMINAL INPUT RATINGS AND GAS FLOW on Page 1. 6. Note the following comments and procedures to assure correct gas supply pressure and adjusting the gas valve to obtain proper orifice (manifold) pressure. XI.
SECTION 2 INSTALLATION SPECIAL NOTICES: The ovens should be operated only in an area that has good air circulation. The oven must be installed under an electrically powered ventilating hood. Installation of replacement parts requiring access to the interior of the oven is permitted only by authorized service personnel. The operator should be properly trained to the functioning of the oven. This instructions manual should be supplied to the operator.
