TABLE 2. DUCT WORK INSTALLATION GUIDELINES
•Keep duct runs as short and straight as possible.
•Duct fittings (elbows and transitions) reduce air flow efficiency.
•Back to back elbows and "S" turns significantly reduces air flow and are not recommended.
•A short straight length of duct at the inlet of the remote blower gives the best delivery.
•Transition to round duct as close to the Cook‘n’Vent® as possible. In order of preference, use
1st. 10" round duct 2nd. 8" round duct 3rd. 7" round duct 4th.
•The use of flexible metal round duct should only be used when no other duct fitting exists. Limit use to short lengths and do not crush when making corners.
•Where local codes permit, plastic pipe (PVC- schedule 40 pipe or ABS pipe 7" or 8" diameter) can be used in areas of high ground moisture and in slab floors to eliminate future rusting.
•Use only duct work constructed of materials that are acceptable by the applicable codes. All duct should be 26 gauge or heavier to minimize flex due to air flow.
•If the VTR1000Q is used, then a 10" diam. round duct to match the inlet ring is required or a transition
to a 10" diam. is necessary from other duct sizes.
•If the VTR600R is used, then a 8" diam. round duct to match the inlet ring is required or a transition to a 8" diam. is necessary from other duct sizes.
•Use sheet metal screws as required to support the
duct weight, and seal all joints with duct tape.
•Be certain that the duct work does not interfere with floor joists or wall studs.
•Do not exhaust more than one vent into a single duct run.
•Thermal breaks, such as a short section of nonmetallic duct, should be used in areas of extreme cold.
•Always use an appropriate roof or
STEP 2
PREPARE COUNTERTOP CUTOUT
For installation of the Cook'n'Vent® with a Thermador cooktop, refer to Part A and Figure 7. For installation with another brand of cooktop, refer to Part B and Figure 8.
For all installations, verify cutouts will clear the inside of the front countertop support rail. (See cutout depth in Figure 2). The front and rear cutouts must be straight and parallel to the front edge of countertop and the rear backsplash or wall. Assure that the side cutouts are square to the front and rear cutouts. All illustrations and dimensions are based upon standard 24" deep by 36" high American style base cabinets with 25" countertops.
When installing laminated or solid surface countertops
such as Surell™ and Corian®, be sure to follow the countertop manufacturer's instructions regarding mini- mum corner radii, reinforcement of corners, etc.
For overhead cabinet and cooktop side clearances consult cooktop Installation Instructions.
A.INSTALLATION WITH A THERMADOR COOKTOP (FIGURE 7 AND TABLE 3)
Provide an opening in the countertop as specified in Table 3. Make sure the distance from the front of the countertop to the front of the cutout is not less than dimension "SB." Verify that the available flat countertop is greater than dimensions "OW" by "OD." Make certain the backsplash thickness does not exceed dimension "BT".
