This unit can be vented vertically through upper cabinets or
horlzontally through an outside wall. A typical vertical installation is
shown in Figure 1. A typical horizontal installation is shown in Figure
2. For proper ventilation when used with an indoor electric grill, see
page 4for guidelines for proper duct sizing. Improper duct sizing or
lnsfallation of restrictive roof jacks can reduce air moving capacity
and provide inadequate ventilation ior an indoor electric grill.
For most eflicient smoke removal, the top of the hood should be
approximately 66 inches (167.6 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 W’ (.6
cm) clearance on all four sides for back vent. Allow J/4”(1.9
cm) clearance toward front for vertical vent. Allow %” (.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 page 6.
6. Remove screw holding junction box cover.
7. Remove proper electrical knockout. See Figure 3.
8. Remove proper venting knockout. See Figure3. 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.

Guidellne to Proper Duct Sizing for Ventllattng An Indoor Electric Grill
These Guidelines are to insure adequate ventilation for an
indoor Electric Grrll. Indoor electric grtlls produce more smoke
than normal cooking and requrres at least 410 CFM to provtde
adequate ventrlation. Less strmgent ventilating requirements
can devrate from these recommendattons.
HORtZONTAL VENTtNG
Figure two on page two shows a direct aischarge to the
outside through a wall rain cap. Due to the lower CFM rating In
thus venting posrtron, duct must be limrted la 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 9shows an installation requiring more duct length. A
transrtion to round is used as close to the hood as possible to
eliminate the restriction caused by the 3% x 10 duct. 4S0 bends
should be used instead of 90° bends wherever possrble.
VERTICAL VENTING:
Figure one on page two shows an installation using 3 feet of
3% x 10 inch duct termrnating 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 45O elbow can be
approximated by dtvtding the equivalent duct lengths In Table 2
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 4S0 elbow (8” Dia.)
15 ft.
Fifteen feet is over the maximum of 13 ft. for 8” dia. duct, so 8”
duck is too small.
Move to 9” dia. duct and run through the calculatrons again.
9 ft. Straight Duct,
7 ft. Equivalent strarght length of 9” dia. duct for 45O elbow.
16 ft.
Sixteen feet is under the maximum of 25 ft. for 9” dia. duct, so 9”
duct is a good choice.

TROUBLE SHOOTING PROCEDURE
lf entire unit is not working, proceed as follows:
1. Check circuit breaker box to insure that breaker for hood is not tripped.
2. Remove printed circuit board enclosure cover by removing two screws securing the cover.
(See Figure I .)
CAUTION: SHOCK HAZARD
SOME CIRCUIT BOARD COMPONENTS (INCLUDING HEAT SINKS) ARE NOT ISOLATED FROM
THE AC POWER LINE.
3. Disengage five pin connector from P. C. board and check for 115VAC (nominal) AC line voltage
between the black wire socket (end socket) and white wire socket (center socket) by inserting
VOM probes into sockets.
4. If voltage is not present, proceed as follows:
a. Turn off power at breaker box.
b. Check connections in rear power entry box. (See Fig. 1.)
(1) Push in filter retainmg tabs and remove filter from wiring compartment.
(2) Remove cover retaining screws and cover.
(3) Remove wiring box covers (2).
C. Check continuity of wires from wire nut connections to P. C. board sockets by inserting one
meter probe in wire nut connection and the other probe in respective socket connector.
d. Repair or replace as required, restore power to unit and again check for voltage at P. C. board
connector.
5. If the fan or light still does not operate, proceed as follows:
a. With five pin connector plugged into board and light and/or fan turned on, check output of the
red (light) and blue (fan) wires in the five pin connector by inserting one probe of the meter in
the backof thesocket at therespectivewireconnection (redor blue) andtheotherprobein the
back of the socket at the black wire connection.
(1) Reading for red wire output should be 50-65 VAC if the light is on “Lo” or loo-125 VAC if
the light is on “Hi”.
(2) Reading for blue wire output should be between 72 VAC and the line voltage reading,
depending upon fan speed setting.
b. If output readings are correct, problem is in the wiring from plug to devices (fan and light) or in
the devices themselves. (Bad socket or bulb and/or defective fan motor.)
C. If outputs are not correct, problem is in the circuit board or membrane switch. (See Page 2.)

c. Remove three screws securing board to the enclosure and remove board.
d. Replace with new circuit board and re-assemble by reversing above procedure. Be sure that
the switch flex tail is inserted far enough into its connector that the locking teeth on the
connector tab engage the slots in the switch tail.
i’. If unit still does not operate, check membrane switch by removing switch tail from connector and
inserting tail of a new unattached membraneswitch in connector from P. C. board sideof hood and
secure with tab. Insure that tail is oriented same as tail on attached switch. Operate switch and if
unit operates, replace attached switch with new switch. To replace membraneswitch, proceed as
follows:
a. Release switch flex tail from P. C. board connector.
b. Remove front trim by removing screws securing trim to hood. Be careful not to scratch or
otherwise damage trim.
C. Remove switch by carefully running a sharp thin knife or razor blade under edge of switch to
break adhesive loose at one end of switch. Pull switch with steady outward pressure.
d. Replace switch by removing paper backing, inserting flex tail in hood front slot and
CAREFULLY aligning switch before allowing adhesive to secure switch to front panel.
Remove switch front protective coating by carefully peeling off of switch.
e. Insert flex tail into circuit board connector and secure with locking tab.
