General Information

900 Series Cabinet Unit Heaters are designed and UL & cUL
Listed to be applied as Standard Free Air heaters with both
louvered intake and louvered discharge panels for recess or
surface installation: a) on the floor, with front inlet and up flow
air movement in the up flow, down flow, left or right direction or
b) on the ceiling, or Ducted (0.2” wg external static pressure)
flange for direct connection of field supplied ductwork to the
inlet, discharge, or both inlet and discharge. Ducted heaters
can be installed for recess or surface installation: a) on the
floor, with front inlet and up flow air movement, b) on the wall,
with air movement in the up flow or down flow direction or c)
on the ceiling.

See Figure 1 for Mounting Clearances.

Note: Keep all furniture or any other blocking material at least

24” (610mm) away from front of heater.
When draperies are used, hang them so that when in use they
are at least 6” (153mm) above the top of front discharge
heater.
Do not use draperies with top discharge heaters.

See Figure 2 for Mounting Dimensions
See Figure 3 for Duct Collar Dimensions and Installation
Details.

FLOOR MOUNTING

Heaters with front inlet and up flow air movement

1.
may be mounted directly on any floor surface
including carpeting. Where wall to wall carpeting is
installed after heater installation the carpeting can be
run up to the front and around the heater body. See
Figure 1 for mounting clearances.

2. Heaters can be mounted on either end with air movement

left or right directly on any floor surface including carpeting.
See Figure 1 for mounting clearances.

3. If optional kick plate is not used, proceed to “HEATER

INSTALLATION” section.

INSTALLATION OF OPTIONAL 900 SERIES

BASE KIT

1. If desired, the heaters may be mounted off the floor with

optional kick plate panel.

2. Align panel on bottom of heater (Inlet side only.)

3. There should be a 1” (25mm) space from the panel to the

front and sides of the heater.

4. Match drill .140” (3.55 mm) diameter holes in the bottom of

the heater and secure with screws provided.

5. Proceed to “HEATER INSTALLATION” section.

CAUTION

TO PREVENT HEATER FROM FALLING AND CAUSING
PERSONAL INJURY, EACH FASTENER, AS APPLIED,
SHOULD HAVE THE HOLDING POWER OF AT LEAST 100
POUNDS (45 kg).

!

WALL OR CEILING RECESS MOUNTING

1. Create on opening in the wall 26-5/8” (676mm) high by the

width of the heater plus 1/4” (6.4mm). Example: If the heater
was 68 inches long, the opening should measure
26-5/8” high x 68-1/4” long).

2. The depth of the recess will vary with the desired amount
of heater recess.

3. Proceed to “HEATER INSTALLATION” section.

INSTALLATION OF OPTIONAL

900 SERIES RECESS TRIM KIT

1. Determine depth of heater recess.

2. Align recess trim frame so that the trim frame front edge
will touch wall when heater is installed.

3. Match drill .140” (3.55mm) diameter holes in all four sides of
the heater and secure trim frame with screws provided.

4. Proceed to “HEATER INSTALLATION” section.

HEATER INSTALLATION

1. Rough-in electrical wiring. See Figure 2 for knockout locations.

2. Remove the proper knockout in the heater or punch the
proper size hole in the bottom or right side of the heater as
shown in Figure 2.

3. Remove the front cover by rotating the lock(s)
counter-clockwise (ccw).

4. Remove Top (Discharge) Louver Panel by removing 2
screws (one on each end) that attach the louver panel to
the end panels.

5. Refer to Figure 3 for location of mounting holes.

6. Mark and drill holes for heater attachment in wall or ceiling.

7. Install heater in opening and tighten screws (field supplied)
to insecure tight fit of the heater against the mounting
surface.

NOTE: Tightening the heater against an irregular wall
will cause distortion of the back panel of the heater. If
this is the case, shims should be used behind the back
panel to keep it straight.

8. Reinstall the Top (Discharge) Louver Panel by sliding the
panel into the heater. Position the panel tabs of the louver
panel to rest on the top of the lip of the heater back.
Position the louver panel top even with the top of the end
panels. Tap the louver panel at the top front (both sides) to
seat the panel. Reinstall 2 screws (one on each side) that
attach louver panel to the end panels.

9. WIRING - See wiring section.

10.After wiring is complete, insure that the control box cover is
closed and fastened and that the filter is installed.

11.Adjust the thermostat to the desired set point.

12.Adjust the heat selector to the heat and fan speed desired.

13.Replace front cover and secure by turning the locks
clockwise (cw) until tight. Replace plug buttons provided.

14.Leave the heater running a few hours before making any
further change in thermostat setting.

DUCTED APPLICATIONS

1. See Figure 3 for duct flange size and location.

2. Duct collars have been factory located (Bottom inlet, Front
inlet, Top discharge, Front discharge) as ordered.

!

WARNING

TO REDUCE RISK OF FIRE AND ELECTRICAL

SHOCK: DO NOT EXCEED 0.2” WG EXTERNAL STATIC

PRESSURE. DO NOT MOUNT HEATER ON END PANEL

(LEFT OR RIGHT AIR FLOW).

3. To change duct collar location:

A. Heater duct panels are supplied with a duct collar attached

to one surface and a blank-off plate attached to the other
surface. The location of the duct collar and the blank-off
plate can reversed.

B. Remove screws holding blank-off plate and remove

blank-off plate.

C. Remove screws holding duct collar and remove duct collar.
D. Position duct collar to location desired, align screws holes,

insert and tighten screws to secure duct collar to duct
panel.

E. Position blank-off plate to location desired, align screw

holes, insert and tighten screws blank-off plate to duct
panel.

4. Position field ductwork to outside of heater duct flange.

5. Mark and drill starting holes in duct and flange.

6. Install and tighten screws (field supplied) to provide a
secure seal.

!

WARNING

TO REDUCE RISK OF FIRE AND ELECTRICAL

SHOCK: DO NOT USE 100% OUTSIDE AIR DAMPER

OPTION WITH BOTTOM AIR INLET. USE ONLY FRONT AIR

INLET WITH 100% OUTSIDE AIR DAMPER OPTION.

OPTIONAL

100% OUTSIDE AIR DAMPER

1. Flange brackets for the rear mounted duct collar are
packaged unassembled in the heater carton.

2. See Figure 2 for location of damper opening.

3. Position the top flange bracket with the flange at the top of
the damper opening and holes in the flange align with
holes in the cabinet back.

4. Attach flange to cabinet with screws provided.

5. Position and attach remaining three (3) flange brackets
around damper opening.

6. Position field ductwork to outside of flange brackets.

7. Mark and drill starting holes in duct and flange.

8. Install and tighten screws (field supplied) to provide a
secure seal.

OPERATION OF OPTIONAL

100% OUTSIDE AIR DAMPER

1. Controls, consisting of an “OPEN-CLOSED” switch and
100% positioning potentiometer, are located on the
control panel door.
