READ AND SAVE THESE INSTRUCTIONS
Before you begin, read the following instructions
completely and carefully. If followed, they will simplify
the installation job.
IMPORTANT: OBSERVE ALL GOVERNING CODES
AND ORDINANCES
SAVE THESE INSTRUCTIONS FOR THE LOCAL
ELECTRICAL INSPECTOR’S USE
This unit can be vented vertically through upper cabinets or
horrzontally through an outside wall A typrcal vertical rnstallatron IS
shown In Figure 1. A typical honzontal installation IS shown In Figure
2. For proper ventilation when used wrth an Indoor electric grill, see
page 4for guldelines 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 66 inches (167.6 cm) from the floor.

1. Make atemplateortransfer measurements shown in Fig. 3
to cabinets or wall.
2. Cut holes to accomodate ventilating duct allowing W’ (.6
cm) clearance on all four sides for back vent. Allow %” (1.9
cm) clearance toward front for vertical vent. Allow W’ (.6 cm)
on other three 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. Remove blower housing and filters for easier installation
See exhaust unit assembly illustration on back page.
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 damper as shown 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 applicable local
codes and/or latest National Electrical Code for electrical
conector 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 4
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
L,ocal codes.
16. Replace junction box cover.
17. Replace blower. Note different blower positions in
Figure 5 for vertical venting and Figure 6 for horizontal
venting. See Page 3 for correct blower installation.
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 where it passes through
outside walls or ceiling. Seal around electrical wiring also.
19. Be sure that damper which is supplied with this model is
properly installed. (See Figures 1 & 2).

NOTE: Before reinstalling the blower Assembly, check the
damper for free operation. Open the damper blade and
check for any restrictions in the duct system. Check
installation instructions for proper duct sizing.
Correct Blower orientation is imperative. Incorrect
installation will drastically cut air flow and cause Blower to
run at maximum RPM regardless of motor speed control
setting.

2. From the blower position shown in Figure 7. lift the

3. The 3” blower discharge surface should now be flush

blower through the top vent. (The wider 5” surface will be to
the rear.)

These Guidelines are to insure adequate ventilation for an
indoor Electric Grtll. Indoor electric grills produce more smoke
than normal cooking and requires at least 410 CFM to provrde
adequate ventilation. Less stringent ventilating requirements
can deviate from these recommendations.
HORIZONTAL VENTING
Figure two on page two shows a direct drscharge to the
outside through a wall rain cap. Due to the lower CFM rating in
this venting posrtion. duct must be ltmited to a maximum of 2
feet of 3% x 10 inch duct capped with 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.
Figure Sshows an installation requiring more duct length. A
transition to round is used as close to the hood as possible t0
eliminate the restriction caused by the 3% x 10 duct. 4S” bends
should be used instead of 90° bends wherever possible.
VERTICAL VENTING:
figure one on page two shows an installation using 3 feet of
3% x 10 inch duct terminating in a roof rain cap. In table one we
see that 3 feet of 3% x 10 inch duct is the maximum length of 3% x
10 inch duct recommended.
For example, if the straight lengths of duct in Fig 9 total 9 ft.
the elbow is 45O and the roof rain cap has 113 in2 free area.
choose the duct size required. The 45i” elbow can be
approximated by dividing the equivalent duct lengths in Table2
by two.
Since we already have 9 ft. of straight duct, Tdble 1 tells us that
7’ dia. is too small. So we try 8” dia.
9 ft. Straight Duct
6 ft. Equivalent straight length of 45Oelbow (8” Dia.)
15 ft.
Fifteen feat 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 45Oelbow.
16 ft.
Sixteen feet is under the maximum of 25 ft. for 9” dia. duct, SO9”
duct is a good choice.

OPERATION AND CARE OF UNIT
BLOWER CONTROL
Thrs range hood has a solid state motor speed control. This
allows an infinite control of blower air moving capacity from
440 CFM down. Afier setting Ihe control to a desired speed, It
will take approx. 15 seconds for the blower to respond to that
setting.
CARE OF BLOWER
Under normal operating conditions, this blower requires no
oiling for the first yeaf. After the first year oil every 6 months
with SAE 20 oil.
LIGHTING
Do not use bulb larger than 60 watts in light socket.
CARE OF FILTER
for greatest efficiency. the permanen! aluminum filter shoul
be removed and cleaned periodically. The filter can be washe
in a dishwasher.
CARE OF EXTERIOR SURFACES
Your range hood is a beautifully finished addition to yOc
kitchen. To preserve its lasting beauty, Clean with a mil
detergent. 00 NOT use abrasive cleaner?.
for most effective removal of smoke and odors, turn on fan a
beginning of cooking operation and allow to run until smoke
and odors are removed from the room.
