setting.

CAUTION

To eliminate risk of burns or fire caused by reaching over heated surface units, cabinet storage located above the surface units should be avoided.

CAUTION:

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 the range. The maxi-

mum gas pressure to this appliance is not to exceed 14.0 inches water column (34.9 mb) from the propane gas tank to the regulator.

CAUTION

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

This appliance complies with one or more of the following standards:

• UL 858, Standard for the Safety of Household Electric Ranges

Step 1: Ventilation Requirements

It is strongly recommended that a suitable 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 all 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 3" on each side.

IMPORTANT:

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.

Do not install a microwave oven / ventilator combination above the range, as these types of units do not provide the proper ventilation and are not suitable for use with the range.

2. Hood Placement:

• For best smoke elimination, the lower edge of the hood should be installed 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 36" 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.

Notes:* For wall installations where adequate space is available, the installer or user may elect to

use a hood that is wider than the rangetop cooking surface. This may be particularly beneficial for installations having a long duct run or when heavy usage of the grill is anticipated, in which improved capturing of the cooking exhaust is desired.

** Thermador offers a choice of remote (VTR1030D or VTR1530D) or internal (VTN1030C) 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 36" ranges may be recessed into the cabinets beyond the edge of the front face of the oven (See Figures 2A and 2B). The 30" and 48" ranges are not approved to be installed flush with the cabinets.

CAUTION

In these installations, the door and cabinet on 36-inch models can cause a pinching hazard.

3. The gas and electrical supply should be within the zones shown in Fig. 3A.

4. Any openings in the wall behind the range and in the floor under the range must be sealed.

5. 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 Pot and Pan 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). Figures 2A and 2B indicate the space required for each type of backguard.

6. A three (3) inch minimum clearance is needed when the range is installed beside a combustible side wall.

7. Always keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

8. Do not obstruct the flow of combustion and ventilation air to the unit.

NOTE: The maximum depth of overhead cabinets installed on either side of the hood is 13".

A 36-inch minimum clearance is required between the top of the cooking surface and the bottom of an unprotected cabinet. It is recommended that the bottom of the wood or metal cabinet be protected by not less than 1/4 inch of a flame retardant material covered with not less than No. 28 MSG sheet steel,

0.015 inch (0.38 mm) thick stainless steel, 0.024 inch (0.6 mm) aluminum, or 0.02 inch (0.5 mm) thick copper. Flame retardant materials bear the following mark:

UNDERWRITERS LABORATORIES INC. CLASSIFIED MINERAL AND FIBER BOARDS SURFACE BURNING CHARACTERISTICS

Followed by the flame spread and smoke ratings. These designations are shown as “FHC (FIame Spread/Smoke Developed).” Materials with “O” flame spread ratings are flame retardant. Local codes may allow other flame spread ratings.

As defined in the “National Fuel Gas Code” (ANSI Z223.1, Current Edition).

Step 2: Cabinet Preparation

CAUTION:

Do not install the 30" and 48" ranges such that the oven door is flush with the cabinet face. the cabinets due to exposure to high heat.

The Dual Fuel ranges may be connected to the power supply with a range supply cord kit or by hard-wiring to the power supply. It is the responsibility of the installer to provide the proper wiring components (cord or conduit and wires) and complete the electrical connection as dictated by local codes and ordinances, and/ or the National Electric Code. The

units must be properly grounded. Refer to Step 6 for details.

The range must be connected only to the type of gas for which it is certified. If the range is to be

connected to propane gas, ensure that the propane gas supply tank is equipped with its own high pressure regulator in addition to the pressure regulator supplied with the range. (See Step 5.)

ELECTRICAL SUPPLY

Step 2: Cabinet Preparation

Installation of the range 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" from the rear wall. See Figure 3B.

FIG. 3B 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 Figure 8 on Page 14 for location of junction box on unit. To minimize binding when the unit is connected to the receptacle or junction box, orient the receptacle or conduit connector, and slide back into position.

Step 3: Un packing, Moving and Placing The Range

CAUTION

Proper equipment and adequate manpower must be used in moving the range to avoid injury, and to avoid damage to the unit or the floor. The unit is heavy and should be handled accordingly.

• The range has an approximate shipping weight as shown in Chart A. The grates, griddle plate and frame, burner caps, front kick panel and oven racks must 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 Figs. 2A and 2B on Page 5. Do not remove the

grill or griddle assemblies.

FIG. 4 – Removal of Two Front Shipping Bolts

FIG. 5 – Removal of Two Rear Shipping Bolts

Left Rear Shipping Bolt

• Remove the outer carton and packing material from the shipping base. The dual fuel ranges are held to the skid by four (4) bolts (see Fig. 4 and 5). After removing the bolts the range must be lifted and removed from the skid.

• Remove angle-mounting brackets from range. This requires the installer to remove two screws holding each bracket then remove bracket and reinstall screws.

NOTE: Leave adhesive-backed foam layer over brushed-metal surfaces, to protect finish from scratches, until the range is installed in final position.

IMPORTANT: Do not lift the range by the oven door's handle, as this may damage the door hinges and cause the door to fit incorrectly to the oven cavity.

Step 3: Un packing, 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. 6).

• 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 BEFORE PUSHING THE UNIT INTO POSITION. The anti-tip device

must be installed (Step 4), gas and electrical connections should be made (Steps 5 and 6), and the backguard installed (Step 7) before the range is placed in its final position.

• For proper performance the range must be level. (It is very important for all products that have the griddle feature). The range is leveled by adjusting the legs with a wrench.

• Replace the kick panel and install the oven door. To install door, see Page 17. Do not

install the oven door until the range is in its final location. It is important that the two (2) screws retaining the kick panel are secure to prevent accidental access to hot surfaces.

FIG. 6- Dolly Positioning

Remove all tape and packaging before using the appliance. Destroy the packaging after unpacking the appliance. Never allow children to play with packaging material.

• Ensure that the burner caps are correctly

seated on the burner bases of the range's cooktop.

Grill / Griddle Tilt Adjustment (Not on all models)

Check the griddle adjustment by pouring two tablespoons of water on the back of the griddle plate. The water should slowly roll into the grease tray. If not, adjust the two screws under the back of the griddle. Start with one half turn counter clockwise (CCW) of the screws. Further adjustment should be made by one-quarter turn until water slowly flows into the grease tray.

Step 4: Installing Anti-Tip Device

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

W ARNING

RANGE TIPPING HAZARD

• All ranges can tip and injury can result. To

prevent accidental tipping of the range, attach it to the floor, wall 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 can result in tipping of the range. Personal injury might result from spilled hot liquids or from the range itself.
