SECTION 2 - INSTALLATION B. Stacking Figure 2-8 - Stacking and Top panel installation For single ovens, skip ahead to Part C, Restraint Cable Installation. #10 x 2" screws Top panel • • ENGLISH IMPORTANT Blodgett STRONGLY RECOMMENDS that BG2136 oven cavities be stacked using the following: PS500 Series Stacking Lift Kit, P/N 30580 BG2136 Stacking Hardware Kit, P/N 46494 Contact your Blodgett Authorized Service Agent for complete stacking instructions. 1.
SECTION 2 - INSTALLATION ENGLISH D. Conveyor Installation 1. Unfold the conveyor as shown in Figure 2-10. Then, begin to slide the conveyor into the end of the oven. The conveyor can only be installed from the end of the oven with the drive motor. 2. Continue moving the conveyor into the oven until the frame protrudes equally from each end of the oven. Check that the crumb tray supports located on the underside of the conveyor frame rest firmly against the lower end plugs, as shown in Figure 2-11.
5. If it is necessary to add or remove conveyor links to achieve the correct tension, OR if it is necessary to reverse the conveyor belt for correct orientation, the belt will need to be removed from the conveyor frame. If this is necessary, perform the following procedure: E. Final Assembly 6. Install the drive chain between the conveyor drive sprocket and the motor sprocket. To install the chain, it will be necessary to lift the drive end of the conveyor slightly.
SECTION 2 - INSTALLATION IV. ELECTRICAL SUPPLY ENGLISH WARNING Authorized supplier personnel normally accomplish the connections for the ventilation system, electric supply, and gas supply, as arranged by the customer. Following these connections, the factory-authorized installer can perform the initial startup of the oven. The oven requires a ground connection to the oven ground screw located in the electrical junction box. (The box is shown in Figure 2-14.
NOTE: Certain safety code requirements exist for the installation of gas ovens; refer to the beginning of Section 2 for a list of the installation standards. In addition: • In the USA, the installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1. • In Canada, the installation must conform with local codes, or in the absence of local codes, with the Natural Gas Installation Code, CAN/CGA-B 149.
SECTION 2 - INSTALLATION ENGLISH 1. Checking the Gas Supply (Inlet) Pressure a. With the main gas supply valve closed and the circuit breaker/fused disconnect in the OFF ("O") position, open the inlet pressure tap shown in Figure 2-17 and attach a manometer to the tap. b. Depress the safety switches to allow the oven to operate. c. Open the main gas supply valve. Switch the circuit breaker/ fused disconnect to the ON ("I") position. d.

SECTION 4 - MAINTENANCE WARNING 1. 2. 3. 4. Switch off the oven and allow it to cool. Do NOT service the oven while it is warm. Turn the full-flow gas safety valve to the off position. Turn off the electric supply circuit breaker(s) and disconnect the electric supply to the oven. If it is necessary to move a gas oven for cleaning or servicing, disconnect the gas supply before moving the oven. When all cleaning and servicing is complete: 1.
SECTION 4 - MAINTENANCE Figure 4-2 - Removing Air Fingers and Plates II. MAINTENANCE - MONTHLY Check that the oven is cool and the power is disconnected, as described in the warning at the beginning of this Section. B. Refer to Part D, Conveyor Installation, in the Installation section of this Manual. Then, remove the following components from the oven: • Conveyor end stop • Crumb trays • Chain cover • Drive chain • End plugs • Conveyor assembly ENGLISH A. C.
SECTION 4 - MAINTENANCE Remove the master links from each conveyor belt. Then, roll the belts up along the length of the conveyor to remove them from the frame. 3. Remove the two conveyor adjustment screws from the idler end of the conveyor frame, as shown in Figure 44. 4. Remove the idler shaft assembly from the conveyor. 5. Pull apart the two sections of the idler shaft. 6. Clean the shafts thoroughly using a rag.
Blower Belt 1. Remove the six screws shown in Figure 4-7. Then, remove the rear panel from the oven. 2. Check the blower belt for the proper 1/4" (6mm) deflection at the center, and for cracking or excessive wear. See Figure 4-7. Overtightening the belt will cause premature bearing failure and possible vibrations. A loose belt may also cause vibrations. 3. If necessary, adjust the tension of the belt by loosening the four motor mounting bolts.
