VENT AND COMBUSTION AIR HOODS

The vent and combustion air hoods are shipped attached to the

blower housing in the blower compartment. These hoods must

be installed on the outside of the gas heat panel to ensure

proper unit function. The necessary mounting screws are

provided in a bag that is also attached to the blower housing.
The screen for the combustion air intake hood is secured to the

inside of the access panel opening with three fasteners and the

screws used for mounting the hood to the panel. The top flange

of this hood slips in under the top of the access panel opening

when installing. Refer to Figure 6. Remove the protective label

covering the opening just prior to installing this hood.
The vent hood (including its screen) is installed by inserting the

top flange of the hood into the slotted opening in the access

panel. The top screw secures the hood to the access panel.

The remaining two side screws must be installed after the

access panel is installed on the unit. These screws engage the

bottom flue box flange.

CAUTION: All three screws in the vent hood must be properly

installed before furnace operation to insure all

combustion products are exhausted from the unit.

OPTIONAL ECONOMIZER RAIN HOOD

The following procedure should be used when assembling an

economizer rain hood onto a unit. Refer to Figure 7. The

outdoor and return air dampers, damper actuator, the linkage

and all the controls are factory mounted as part of the

economizer option.
All of the hood components, including the filters, the gasketing

and the hardware for assembling are located above the top

filter racks within the filter section. The outdoor air sensor is in

the bag of parts located at the bottom of the return air section.

1. With filter section access panel removed, take out hood

components, filters and sensor described above. Remove

and discard outdoor air opening cover on back unit (Upper

right hand corner).

2. Remove the 1/2" knockout (A) in the units rear panel

(located to the right side of the outdoor air opening). Insert

the two loose wires from inside the unit, into the 1/2"

bushing provided. Insert wires and bushing into knockout.

Snap bushing into place.

3. Mount the outdoor air sensor to the rear panel, just below

the knockout described in Step 2. Secure with two self-

drilling screws at dimples (B) provided in the panel.

NOTE: Sensor must be positioned so that the sensing ports

are at the top (louvers pointing downward) and termi-

nal connections to the right.

4. Connect the two wires, indicated in Step 2, to the sensor as

follows:

Wire #73 to terminal (+)

Wire #74 to terminal (S)

5. Assemble the LH and RH side plates to the top cover (2

screws each side) to form the hood. Apply gasketing to the

flange surface on each side plate. Extend gasketing 1/4"

beyond top and bottom of each flange to insure adequate

corner sealing. Secure this assembly to the unit back panel

(upper right hand corner). First, remove screw (C) on unit

top cover. Then slip flange of hood cover in under flange of

unit top cover, replace screw (C), engaging hole (E) in hood

flange and tighten. Attach the two side plates to the unit

panel by using two self-drilling screws for each side plate at

dimples (D) provided in the panel.

6. Position fillpiece at bottom of hood, between the two side

plates but do not secure at this time. (Slotted openings

MUST be downward for drainage). After fillpiece is properly

positioned, note where contact is made with the unit panel.

Remove fillpiece and apply gasket material to this area to

provide a seal. Reposition fillpiece and secure with 2

screws.

7. Install the two filters into the hood assembly, sliding down

along retainers on side plates, into fillpiece at bottom of

hood.
