IMPORTANT NOTES:
• It is recommended that a

blowers, and accessories.
• For high output gas ranges (60,000 BTU or greater), the minimum of one (1) CFM of ventilation per 100 BTU is
recommended. If the range has a griddle, add 200 CFM to the estimated blower capacity. Additional blower capacity
may be required for longer duct runs. (CFM = "cubic feet per minute", standard blower capacity rating).
• For island applications, it is recommended to use a hood width that exceeds the width of the range by 6" (152 mm),
overlapping the range by a minimum of 3" (76 mm) on each end.

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" on page 5 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.
• The range should not be recessed into the cabinets
beyond the edge of the front face of the oven (see
clearances beginning on page 6).
• The gas and electrical supply should be within the
zones shown in Figure on page 8..
• Any openings in the wall behind the range and in the
floor under the range must be sealed.
• When installing against a combustible surface, a High
Shelf or Low Backguard is required. A THERMADOR
High Shelf or Low Backguard must be purchased
separately (see Table 4, "Backguard Kit Model
Numbers," on page 17).
• When using the Flush Island Trim, THERMADOR
recommends a minimum 12" (305 mm) rear clearance
to a combustible surface (see Figure 3, Installation
Clearances with Flush Island Trim). 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 (Figure 1).

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) (Figure 1).
• 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.

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.
