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 Figure 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 Figure 1. 2. These ranges may be recessed into the cabinets beyond the edge of the front face of the oven (See Figure 2). 3. The gas and electrical supply should be within the zone shown in Figure 3a. CAUTION: In these installations, the door and cabinet can cause a pinching hazard. Note: The maximum depth of over head cabinets installed on either side of the hood is 13" (330 mm). A 36-inch minimum clearance is required between the top of the cooking surface and the bottom of an unprotected cabinet. A 30-inch clearance can be used when the bottom of the wood or metal cabinet is 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 (0.4 mm) thick stainless steel, 0.024 inch (0.6 mm) aluminum, or 0.020 inch (0.5 mm) thick copper. Flame retardant materials bear the 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. 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 Δ and the back edge of the range above the cooking surface, a Thermador Low Back or Pot and Pan Shelf must be installed. (See Figure 2). When clearance to combustible material Δ is over 12", a Thermador Flush Island Trim may be used. Figure 2 indicates the space required for each type of backguard. 6. Always keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids. 7. Do not obstruct the flow of combustion and ventilation air to the unit. 8. A 5 inch minimum clearance is needed when the range is installed beside a combustible side wall. Δ As defined in the "National Fuel Gas Code" (ANSI Z223.1, NFPA 54 Current Edition). English 4

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
Figure 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 Figure 1.
2.
These ranges may be recessed into the cabinets
beyond the edge of the front face of the oven (See
Figure 2).
3.
The gas and electrical supply should be within the zone
shown in Figure 3a.
CAUTION:
In these installations, the door and cabinet can
cause a pinching hazard.
Note:
The maximum depth of over head cabinets installed on
either side of the hood is 13" (330 mm).
A 36-inch minimum clearance is required between the top
of the cooking surface and the bottom of an unprotected
cabinet. A 30-inch clearance can be used when the bottom
of the wood or metal cabinet is 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 (0.4 mm) thick
stainless steel, 0.024 inch (0.6 mm) aluminum, or 0.020
inch (0.5 mm) thick copper.
Flame retardant materials bear the 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.
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
Δ
and the back edge of
the range above the cooking surface, a Thermador
Low Back or Pot and Pan Shelf must be installed. (See
Figure 2). When clearance to combustible material
Δ
is over 12", a Thermador Flush Island Trim may be
used. Figure 2 indicates the space required for each
type of backguard.
6.
Always keep appliance area clear and free from
combustible materials, gasoline and other flammable
vapors and liquids.
7.
Do not obstruct the flow of combustion and ventilation
air to the unit.
8.
A 5 inch minimum clearance is needed when the range
is installed beside a combustible side wall.
