for use with propeller and blower type unit heaters.

It is important that the deflector hoods be assembled as a

separate piece prior to installing the hood on the unit heater.

Attaching a deflector hood to your unit heater changes the

center of gravity. The field adjustable level hanging feature on

units with two point suspensions allows you to compensate for

this new center of gravity.

Page 3 of your installation and service manual under “unit

suspension”, explains how to make these adjustments. The unit

should be lifted off the floor slightly to make sure your largest

adjustment results in the unit being “close to level”. Once the

unit is suspended, only

““mmiinnoorr ttaappppiinngg ooff tthhee uunniitt iinnttoo iittss ffiinnaall

ppoossiittiioonn””

should take place.

The recommended procedure for assembly and installation is

described as follows:

SStteepp 11..

Before beginning assembly of the accessory hood,

remove all of the spring loaded louver blades from the

unit heater on which the hood is to be installed. These

louver blades will be relocated in the face of the hood

assembly after the hood is attached to the unit heater.

To remove the spring loaded louver blades, simply

apply pressure against the louver blade retaining

spring by grasping the blade and forcing the blade to

the left as you face the unit heater. After compressing

the spring, the right hand tab of the louver blade can

be removed from the unit, and then the spring end of

the blade removed.

NNOOTTEE::

Be sure not to lose the louver blade retaining

springs as they will be required later to install

the blades into the hood assembly.

On the larger size models there are two sets of louver

blades installed with a support channel between them;

remove both sets of louver blades and the vertical

support channel.

SStteepp 22..

All deflector hood kits contain a top panel with a

hooked flange (see Inset A of Figure 1.1). This hooked

flange is designed to hook over the top header flange

of the heat exchanger. However, before this can be

done, the decorative trim channels must be removed

from the top of the air discharge opening of the unit

heater if the unit was supplied with one. (see Figure

1). On all power exhausted models, the trim channel

has been extended to cover the draft relief opening.

Installation of the deflector hood kit requires that this

cover plate be removed on these models.

The trim channel, or cover plate is fastened to the top

header of the heat exchanger with sheet metal

screws. Remove these screws completely and the trim

channel, or cover plate will come free from the unit.
