VENTED RANGE HOOD rgh83oo-is

—r- TO INSTALL RANGE HOOD

This unit can be vented vertically through upper cabinets or horizontally through an outside wall. A typical vertical installation is shown in Figure 1. A typical horizontal installation is shown m Figure

2. For proper ventilation when used with an indoor electric grill, see page 2 for guidelines for proper duct sizing. Improper duct sizing or installation of restrictive roof jacks can reduce air moving capacity

and provide inadequate ventilation for an Indoor electric grill. For

most efficient smoke removal, the top of the hood should be

approximately 55 inches (137.6 cm) from the floor.

1. Make a template or transfer measurements shown in Fig. 3 to

cabinets or wall. ■

2. Cut holes to accomodate ventilating duct allowing ’i" ( 6 cm) clearance on all 4 sides for back vent. Allow (1.9 cm) clearance toward front for vertical vent. Allow Vi" (.6 cm) on others sides for top vent.

3. Cut appropriate hole for electrical wiring.

4. Run wire through wall or cabinets according to National

Electrical Code and applicable local codes. (DO NOT turn power on until installation is complete.)

5. For an easier installation, remove the filters and the three

assemblies shown in Fig. 4. This reduces the weight about 40%. The blov^er cover and light frame assembly are held into place with thumb screv;s. To remove the blower assembly, first unplug the blower power supply cord from the junction box. Remove the packing screw from the blower retaining rod. then pull the blower retaining rod to one side, freeing it from between the bumps on the blower housing.

6. Remove screw holding junction box cover.

7. Remove proper electrical knockout. See Figure 3.

8. Remove proper venting knockout. See Figure 3. NOTE: If

horizontal discharge is selecTed an additional knockout in the blower cradle must be removed.

9. Attach the damoer as shov/n in Figure 5 for vertical discharge or

Fig. 6 for horizontal discharge.

10. Lift the hood into position. Mark location of four mounting holes.

11. Remove hood and start all four screws in center of narrow neck of keyhole slot marked on cabinet bottom.

12. Lift the hood into position simultaneously feeding the electrical

wire through the knockout. Follow aoplicable local codes and/or

latest National Electrical Code for electrical connector to be used at field wiring entrance.

13. Tighten screws to secure hood. Be sure screw head is in narrow neck of keyhole slot.

14. Install proper duct work. See page 2.

15. Complete electrical wiring in junction box according to the National Electrical Code and applicable Local Codes. NOTE: This unit must be permanently grounded in accordance with the National Electrical Code and applicable Local codes.

16. Replace junction box cover.

17. Replace blower. See page 3 for proper blower orientation

18. Replace blower cover, light frame assembly and filters. .

NOTE: It has been found that a large part of the energy loss of the average home is due to outside air infiltrating the structure. Seal around ductwork wnere it passes through outside walls or ceiling. Seal around electrical wiring also. „

Guideline fo Proper Duct Sizing for Ventilating An Indoor Electric Grill

These Guidelines are to insure adequate ventilation for an indoor

Electric Grill. Indoor electric grills produce more smoke than normal cooking and requires at least410CFM to provide adequate

ventilation. Less stringent ventilating requirements can deviate

from these recommendations. HORIZONTAL VENTING;

Figure 2 on page 1 shows a direct discharge to the outside through a wall rain cap. Due to the lov/erCFM rating in this venting position, duct must De limited to a maximum of 2 feet of 3'/* x 10 inch duct capped v/ith a wall rain cap with a free discharge area of at least 66 inches square. There should be no bends in the connecting duct between the hood and the wall rain cap.

VERTICAL VENTING:

Figure 1 on page 1 shows an installation using 3 feet of 3% x 10 inch duct terminating in a roof rain cap. In table 1 we see that 3 feet of 3'.i X 10 inch duct is the maximum length of 3>4 x 10 inch duct recommended.

Figure 7 shews an installation requiring more duct length. A transition to round is used as close to the hood as possible to eliminate the restriction caused by the 3'i x 10 duct. 45:1 bends should be used instead of 90^ bends wherever possible.

For example, ifthestraightlengthsofductinFig.7 total 9 ft. the elbow IS 45^ and the roof ram cap has 113 in' free area, choose the duct size required. The 45’' elbow can be approximated by dividing the equivalent duct lengths in Table 2 by two.

Since we already have 9 ft. of straight duct, Table 1 tells us that 7" dia. IS too small. So we try 8" dia.

9 ft. Straight Duct ‘ 6 ft. Equivalent straight length of 45° elbow (8" Dia.)

15 ft.

Fifteen feet is over the maximum of 13 ft. for 8" dia. duct, so 8" duct IS to small.

Move to 9" dia. duct and run through the calculations again.

9 ft. Straight Duct. 7 ft. Equivalent straight length of 9" dia. duct for 45° elbow

16 ft.

Sixteen feet is under the maximum of 25 ft. for 9" dia. duct, so 9"

duct IS a good choice.
