IMPORTANT INSTALLATION INFORMATION

MPORTANT:

All ranges must be installed with a backguard. Models PRG304 and PRDS304 are shipped from the factory with a standard 9" backguard. For all other models one of three available backguards must be ordered separately and installed at the back of the range. The three backguard choices include a Low Back Guard, High Shelf, or Island Trim. See STEPS 2 and 6.

This appliance has been tested in accordance with ANSI Z21.1 Current Issue, Standard for Household Cooking Appliances (USA) and in accordance with CAN 1.1-M81 Domestic Gas Ranges (CANADIAN).

It is strongly recommended that this appliance be installed in conjunction with a suitable overhead vent hood. (See Step 1 for Ventilation Requirements.) Due to the high heat capability

It is strongly recommended that a suit-

able exhaust hood be installed above the range. Downdraft ventilation should not be used. The table below indicates the Thermador hoods, by model number, that are recommended for use with the 30", 36", and 48" ranges.

1. Select Hood and Blower Models:

• For wall installations, the hood width must, at a minimum, equal the width of the range cooking surface. Where space permits, a hood larger in width than the cooking surface may be desirable for improved ventilation performance.

• For island installations, the hood width should, at a minimum, overhang the range cooking surface by 6" on both sides.

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.

Check local building codes for the proper method of appliance installation. Local codes vary. Installation, electrical connections and grounding must comply with all applicable codes. In the absence of local codes the appliance should be installed in accordance with the National Fuel Gas Code ANSI Z223.1 Current Issue and National Electrical Code ANSI/ NFPA 70-Current Issue. In Canada, installation must be in accordance with the CAN 1-B149.1 and .2 – Installation Codes for Gas Burning Appliances and/ or local codes.

This appliance is equipped with an inter-

STEP 1: VENTILATION REQUIREMENTS

CAUTION: Ventilation hoods and blowers are designed for use with single wall ducting. However, some local building codes or inspectors may require double wall ducting. Consult local building codes and/or local agencies, before starting, to assure that hood and duct installation will meet local requirements.

• Hood blower speeds should be variable to reduce noise and loss of heated or air conditioned household air when maximum ventilation is not required. Normally, the maximum blower speed is only required when using the grill.

2. Hood Placement:

• For best smoke elimination, the lower

mittent/interrupted ignition device that cycles the two far left surface burners on and off when in the ExtraLow

setting.

CAUTION:

(1) When connecting the unit to propane gas, make certain the propane gas tank is equipped with its own high pressure regulator in addition to the pressure regulator supplied with this unit. The maximum gas pressure to this appliance is not to exceed 14.0 inches (37mb) water column from the propane gas tank regulator.

(2) This unit is designed as a cooking appliance. Based on safety considerations never use it for warming or heating a room.

edge of the hood should be installed a minimum of 30" to a maximum of 36" above the range cooking surface. (See Fig. 1).

• If the hood contains any combustible materials (i.e. a wood covering), it must be a minimum of 42" above the cooking surface.

3. Consider Make-Up Air:

• Due to the high volume of ventilation air, a source of outside replacement air is recommended. This is particularly important for tightly sealed and insulated homes.

• A qualified heating and ventilating contractor should be consulted.

30" RANGE

36" RANGE

48" RANGE

Notes: * For wall installations where adequate space is available, the installer or user may elect to use a hood that is wider than the range

cooking surface. This may be particularly beneficial for those cases, such as a long duct run or heavy usage of the grill, in which improved capturing of the cooking exhaust is desired.

** Thermador offers a choice of remote (VTR1000Q or VTR1400q) or in-hood (VTN1000Q) blowers for use in wall installations.

STEP 2: CABINET PREPARATION

1. The range is a free standing unit. If the unit is to be placed adjacent to cabinets, the clearances shown in Fig. 1 are required. The same clearances apply to island installations, except for the overhead cabinets, which must have a space wide enough to accept the flared island hood, as indicated in Fig. 1.

2. The PRDS48 Ranges must be placed with the oven door projecting out from the cabinet face. The cabinet face should line up with the oven front frame, which is the surface that the oven door closes against. (See Fig. 2b and 2c illustrating side views of 48" ranges.)

3. The gas and electrical supply should be within the zones shown in Fig. 3a, 3b and 3c.

FIG. 1 Cabinet Clearances

4. 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). When clearance to combustible material ∆ is over 12", a Thermador Island Trim may be used. (See Fig. 2b). Except in

the case of 30" Ranges, backguards must be ordered separately. Figures 2a, 2b

and 2c indicate the space

STEP 2: CABINET PREPARATION

ELECTRICAL SUPPLY, DUAL FUEL RANGES

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.

FIG. 3d Wall Connection

This is especially critical if the junction box in the wall will be directly behind the junction box on the unit when the unit is installed. Refer to Figures 16 and 16a for location of junction box on unit. Orient the receptacle or conduit connector to minimize binding when the unit is connected to the receptacle or junction box and slid back in position.

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. This will reduce the weight as shown in Chart A and allow the range to pass through 30" doorways. See Chart B and Fig. 2a and 2b. Do not remove the grill or

griddle assemblies.

• Remove the outer carton and packing material from the shipping base. Remove the front kick panel (see Fig. 4) by removing two (2) screws at the top and pulling forward. The dual fuel ranges are held to the skid by four (4) bolts, the front two (2) are behind the kick panel (see Fig. 4) and the rear two (2) are located on the bottom flange of the range back (see Fig. 5). All-gas ranges are held in place by 4 bolts, two (2) as shown in Fig. 4 and two (2) at the rear as shown in Fig. 5. After removing the bolts the range must be lifted and removed from the skid.

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. The anti-tip device (30"

and 36" ranges) must be installed (STEP 4), gas and electric connections should be made (STEPS 5 and

6), and the backguard installed (STEP 7) before the range is placed in its final position.

wires.

Griddle Level Adjustments

• For proper performance the professional range must be level. The range is leveled by adjusting the legs with a wrench. Replace the kick panel and oven doors by reversing the procedure described above. It is important that the

two (2) screws retaining the kick panel are secure to prevent accidental access to live electrical components and

The griddle should be level or tilted slightly forward and should not rock. Screws are installed in the back ledge to eliminate rocking and to adjust the level of the griddle. To access these screws (A) (see Fig. 8), carefully remove the black aluminum trim strips running front to back alongside the griddle, then lift the back of the griddle.

Page 9

Page 12

STEP 4: INSTALLING ANTI-TIP DEVICE

For all 30" and 36" ranges, an anti-tip device must be installed as per these instructions.

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.

• If the range is pulled away from the wall for cleaning, service, or any other reason, ensure that the Anti-Tip Device is properly reengaged when the range is pushed back against the wall. In the event of abnormal usage (such as a person standing, sitting, or leaning on an open door), failure to take this precaution could result in tipping of the range. Personal injury might result from spilled hot liquids or from the range itself.

WARNING

ELECTRICAL SHOCK HAZARD
