Step 2: Cabinet Preparation - Thermador PROFESSIONAL PRO HARMONY Serie Instructions D'installation

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.

STEP 2: Cabinet Preparation

• The range is a free standing unit. If the unit is to be
placed adjacent to cabinets, the clearances shown in
"Installation Clearances" 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.
• Any openings in the wall behind the range and in the
floor under the range must be sealed.
• The gas and electrical supply should be within the
zones shown in Figure 5 on page 11.
• When installing against a combustible surface, a Low
Backguard is required. A THERMADOR
Backguard must be purchased separately (see Table 3
on page 16).
• When using the Flush Island Trim, THERMADOR
recommends a minimum 12'' (305 mm) rear clearance
to a combustible surface (see "Installation Clearances"
beginning on page 7). Clearances from non-
combustible materials are not part of the ANSI Z21.1
scope and are not certified by CSA. Clearances of less
than 12'' (305 mm) must be approved by the local
codes and/or by the local authority having jurisdiction.
• When the range is installed against a combustible side
wall a minimum clearance of 5'' (127 mm) is needed
from the side of the range to the wall.
Installation Instructions
• Always keep appliance area clear from combustible
materials, gasoline and other flammable vapors and
liquids.
• The maximum depth of overhead cabinets installed on
either side of the hood is 13" (330 mm). Wall cabinets
must be 18'' (457 mm) above the countertop.
• The top edges of the range's side panels must be on
the same or higher level as the adjacent countertop. If
the range is operated while at a lower height relative to
the adjacent cabinet, the cabinet could be exposed to
excessive temperatures, causing damage to the
cabinet and countertop.
• DO NOT obstruct the flow of combustion and
ventilation air to the unit.
• There is a 36'' (914 mm) minimum clearance required
between the top of the cooking surface and the bottom
of an unprotected cabinet. A 30'' (762 mm) clearance
can be used when the bottom of the wood or metal
cabinet is protected by not less than 1/4'' (6 mm) of a
flame retardant material covered with not less than No.
28 MSG sheet steel, 0.015'' (0.38 mm) thick stainless
steel, 0.024'' (0.61 mm) aluminum, or 0.02'' (0.51 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. It is the responsibility of
the installer to ensure installation is in accordance with
these ratings.
