IMPORTANT INSTALLATION INFORMATION of this unit, particular attention should be paid to the hood and duct work installation to assure it meets local building codes. To eliminate risk of burns or fire caused by reaching over heated surface units, cabinet storage located above the surface units should be avoided. IMPORTANT: All ranges must be installed with a backguard. Models PRG304 and PRDS304 are shipped from the factory with a standard 9" backguard.
STEP 2: CABINET PREPARATION The maximum depth of over head cabinets installed on either side of the hood is 13". 5. Any openings in the wall behind the range and in the floor under the range must be sealed. 6. When there is less than a 12" horizontal clearance between combustible material ∆ and the back edge of the range above the cooking surface, a Thermador Low Back or High Shelf backguard must be installed. (See Fig. 2a).
STEP 2:CABINET PREPARATION CAUTION: Do not install the Model PRDS304 and PRDS48 ranges such that the front surface of the oven door is flush with the cabinet face. A flush installation could result in damage to the cabinets due to high heat. The face of the cabinet should line up with the oven front frame. The front frame location relative to the rear of the range is 24-3/ 8" on the PRDS304 and 25" on the PRDS48, as shown in Figures 2a and 2b.
STEP 2: CABINET PREPARATION GAS AND ELECTRIC SUPPLY ZONES: FIG. 3a Gas & Electrical Supply Zone for PRG304, PRG36 & PRG48 All-Gas Ranges Typical placement shown. Other placement of Gas Supply and Electrical Receptacle within the Electrical and Gas Supply Zone is acceptable. 5/8" Flex Line to Appliance The All-Gas Ranges are factory equipped with a power supply cord with a three-prong grounding plug.
STEP 2: CABINET PREPARATION ELECTRICALSUPPLY,DUALFUELRANGES Installation of Dual Fuel ranges must be planned so that the rough-in of the junction box for the receptacle or conduit connection will allow maximum clearance to the rear of the unit. When the power supply cord (not supplied) or conduit is connected to the mating receptacle or junction box cover, the combined plug/receptacle or junction box cover/conduit connector should protrude no more than 2-1/4 inches from the rear wall. See Figure 3d.
STEP 3: UNPACKING, MOVING AND PLACING THE RANGE CAUTION: Proper equipment and adequate manpower must be used in moving the range to avoid damage to the unit or the floor. The unit is heavy and rests on adjustable steel legs. • The range has an approximate shipping weight as shown in Chart A. It is recommended that the door(s), grates, burner caps, front kick panel and oven racks be removed to facilitate handling.
STEP 3: UNPACKING, MOVING AND PLACING THE RANGE • Due to the weight, a dolly with soft wheels should be used to move this unit. The weight must be supported uniformly across the bottom (See Fig. 7). • After transporting the professional range by dolly close to its final location, the range can be tipped back and supported on the rear legs while the dolly is carefully removed. THE FLOOR UNDER THE LEGS SHOULD BE PROTECTED (WOOD STRIPS, CARPET, PANELING, ETC.) BEFORE PUSHING THE UNIT INTO POSITION.
STEP 4: INSTALLING ANTI-TIP DEVICE For all 30" and 36" ranges, an anti-tip device must be installed as per these instructions. WARNING WARNING RANGE TIPPING HAZARD • • • All ranges can tip and injury could result. To prevent accidental tipping of the range, attach it to the wall, floor or cabinet by installing the Anti-Tip Device supplied. A risk of tip-over may exist if the appliance is not installed in accordance with these instructions.
STEP 4: INSTALLING ANTI-TIP DEVICE Parts Required for Installation of Anti-Tip Device: PRG304 and PRG36 All Gas Ranges (Figures 9 and 10) Thermador Part No. Qty Description 15-10-916 4 Screw, Phillips,#10 x 1-1/2" 15-10-771 1 Anti-Tip Channel, Adjust able, PRG 15-10-772 1 Mounting Bracket, PRG 15-10-909 1 FIG.
STEP 4: INSTALLING ANTI-TIP DEVICE PRG304 AND PRG36 All-Gas Ranges (Figures 9, 10, 12a 12b and 13) STEP A: Determine the best location for the PRG Mounting Bracket. The bracket may be mounted to the wall or floor behind the range, offset from either the left or right side wall by 2-3/4" for model PRG304 or 4-5/8" for Model PRG36. - Locate the bracket on the side of the range that will not interfere with the gas supply line, electrical wiring, conduit or any other item.
STEP 4: INSTALLING ANTI-TIP DEVICE STEP H: Using the 1/4"-20 x 1/2" Hex Head Bolt, Hex Nut and two (2) Flat Washers, securely attach the Adjustable Anti-Tip Channel to the existing hole in the flange located at the bottom rear of the range. (There are two (2) holes in the range flange, so be certain to select the hole that is on the same side as the mounting bracket.) The flat face of the channel should be flush against the underside of the range flange.
STEP 4: INSTALLING ANTI-TIP DEVICE STEP B: Set the bracket on the floor and turn it until it is oriented properly. The long channel should be on the top with the free end facing towards you, one set of mounting flanges should be resting horizontally on the floor, and the other set of mounting flanges should be positioned vertically facing the rear. FIG. 14 PRDS Wall Mount PLAN VIEW STEP C: Slide the bracket to the desired position. Note that the minimum (dim. "A") and maximum (dim.
STEP 5: GAS REQUIREMENTS AND HOOKUP Verify the type of gas being used at the installation site. As shipped from the factory, all units are configured for use on natural gas. For use with propane gas, the unit must be converted. Field conversion for use with propane must only be done by qualified service personnel. Contact the dealer where the unit was purchased or Thermador (800/735-4328). The field conversion kit for all Professional Gas (PRG series) ranges is Thermador Model PROGASLPKIT.
STEP 6: ELECTRICAL REQUIREMENTS, CONNECTION & GROUNDING • Prior to servicing appliance, always disconnect appliance electrical supply cord, if so equipped, from wall receptacle. If appliance is hardwired to power supply, disconnect power to unit by turning off the proper circuit breaker or disconnecting the proper fuse. • Gas range models PRG304, PRG36 and PRG48 must be plugged into a 3-prong grounding type receptacle. • Dual Fuel range models PRDS304.
STEP 6: ELECTRICAL REQUIREMENTS, CONNECTION & GROUNDING Dual Fuel models PRDS304, PRDS36 and PRDS48 must be connected to the power supply utilizing one of the following methods. For all methods of connection, the length of the cord or conduit/wiring must allow the unit to be slid completely out of the cabinet without having to unplug or disconnect the unit from the power supply. Recommended minimum free length of cord or conduit is four feet.
STEP 6: ELECTRICAL REQUIREMENTS, CONNECTION & GROUNDING A 3 or 4 conductor supply may be connected to the terminal block. A 4 conductor supply shall be used only when the range is installed in a mobile home or where local codes do not permit grounding through the neutral. FIG.17 Conductor Securement ➝ ➝ ➝ ➝ Upper Nut Cupped Washer Supply Wire Flat Washer 3 WIRE LEAD CONNECTION 1. Remove upper nuts only from the terminal block studs. Do not remove nuts which secure range internal wiring leads. 2.
STEP 6: ELECTRICAL REQUIREMENTS, CONNECTION & GROUNDING Recommended Grounding Method – All-Gas Models PRG304, PRG36 and PRG48 The 30," 36" and 48" all-gas ranges are factory equipped with a power supply cord with a three-prong grounding plug (with polarized parallel blades). IT MUST BE PLUGGED INTO A MATING GROUNDING TYPE RECEPTACLE THAT IS CONNECTED TO A CORRECTLY POLARIZED 120 VOLT CIRCUIT. (See Fig. 19).
STEP 6: ELECTRICAL REQUIREMENTS, CONNECTIONS & GROUNDING CASE 2: Electrical Connections and Grounding with a 4-Conductor Power Supply (to be used only when local codes do not permit grounding through the neutral). Secure the neutral (white) wire of the supply circuit to the neutral terminal of the NEMA 14-50R receptacle. Connect the L1 (black) and the L2 (red) hot leads to the other terminals on the NEMA 14-50R receptacle.
STEP 7:BACKGUARD INSTALLATION INSULATION AND RETAINER REMOVAL FIG. 22a Before the backguard can be assembled onto Model PRDS304, PRDS36 and PRDS48 Ranges, the insulation retainer and the insulation must be removed to avoid interference. This insulation is not required on the PRDS304, PRDS36 and PRDS48 models. The High Shelf Back Trim is shown. The procedure is the same for Island Trim or Low Back Trim ➝ Step 1 Remove the four (4) screws holding in insulation retainer. See Fig. 22a.
