Installation Instructions
Designed for high capacity, forced-air applications in
commercial, industrial or institutional buildings. Installs easily
on oors, walls or ceilings, surface or recess mount.
An exploded view of the major components of the CH
Cabinet Heater is shown in Figure 1. The heater is
completely assembled when shipped and must be partially
dismantled for installation.
!
NOTE: This heater is shipped with the outlets in
the front/front (D) conguration, see Figure 7. If another
conguration is required it will be necessary to rearrange the
outlets (See notation REMOVING FRONT PANEL).
REMOVING FRONT PANEL
Remove the cover screws located at top of panel. After
panel is swung open, pull the spring-loaded hinge (located
at one end of panel) towards the centre of the panel. Units
are shipped with doors for upow application. If unit is to
be installed as downow, the panel can be removed and
installed in reverse position. Before mounting the heater
determine the inlet/outlet panel arrangement. Remove the
screws holding the panel(s) in place at the back and at the
front. Reverse the panel(s) and secure back in place.
FASTENING TO WALL
For oor mounted units it is necessary to use only the holes
marked “A” in Figure 3 in order to secure unit to the wall. The
Motor and Blower Assembly need not be removed. The lter
may be removed to assist in installation.
For wall-mounted units, in order to ensure adequate support,
a greater number of mounting holes may be used. To gain
access to them the Motor and Blower Assembly the Filter
must rst be removed. Remove screws at each end of the
Assembly as shown in Figure 2, then pull out Assembly. Be
sure to disconnect plug at the Blower deck before removing
the Assembly. Slide out Filter as shown. The unit is now
ready for securing to the wall.
With ceiling mounted units, use the four (4) 9/16” (14.29 mm)
Figure 1
Filter
Figure 2
diameter knockouts provided on back of unit, use the same
procedure as in the wall-mounted units. Please make sure
that installation is strong enough to support the weight of the
heater.
SEMI/FULL-RECESSED APPLICATIONS
For either semi- or full-recessed applications care must be
taken to provide the proper size of opening in the wall or
ceiling. See Figure 4 for dimensioning details. On the length
and width dimensions, 1/4” (6.35 mm) must be allowed to
insert the trim frame. In a semi-recessed application the unit
can be recessed to any depth except when the inlet and/
or discharge (outlet) are on the top or bottom of the heater
as opposed to the front. Please see Figure 5 for a typical
installation.
ACCESSORY TRIM FRAME ASSEMBLY
Refer to Figure 6 for assembly. Assemble heater frame on
a at surface. Insert “L” shaped splices into each corner
as shown. Use a carpenter’s square to be sure of exact 90
degree angle at corners. Square up one corner at a time,
then centre punch one at a time to crimp down inside ange
onto “L” shaped splice. Trim frame can be secured to wall
with screws (not provided), cement or adhesive.

MOUNTING CLEARANCES
In order for this heater to operate properly the clearances
shown in Figure 8 will have to be maintained. Failing to
do so may result in a poor performance from the heater.
Dimensions are shown in inches (millimetres).
DUCT COLLAR MOUNTING
An 18” (457 mm) section of duct work with 90 degrees bends
may be added to the inlet and outlet of the heater with 8”
(203 mm) clearance to combustible surfaces. Inlet and outlet
grilles placed on the end of the must have a minium of 65%
open area. Refer to Figure 9 for cross-sectional dimensions
of duct. Duct collar inlet/outlets can be as per Figure 7.
Secure the duct to the anges provided.
!
NOTE: External static pressure exceeding 0.15”wg is not
recommended.
WIRING INFORMATION
For service entrance refer to Figure 04 for knockout sizes 1.
available and their locations.
!
NOTE: For upow application, control section and knock-
outs are located on lower right side of unit and for downow
application they will be on upper left hand side of unit.
All external wiring to the heater shall be in accordance 2.
to the Local and National Building codes. It is
recommended that only qualied electrical personnel
shall perform any service on this unit.

Refer to data plate and 3.
wiring diagram for correct

Operation
The CH Cabinet Heater is available with a choice of control
options to provide exibly of operation in various applications.
The type of control option is reected in the Catalogue
Number as the eighth digit. Please check one of the following
options to ensure that is what has been ordered or required.
-3: The unit is automatically controlled by it’s own built-in
thermostat with a range of 45 degrees F (7 C) to 90 degrees
F (32 C). In addition to the toggle switch (“Heat & Fan”,
“OFF” and “Fan Only”) this option has a two position toggle
switch for High/Low Heat Selection and High/Low Blower
Speed. HIGH and LOW Heat give 100% for HIGH and
approximately 50% Low heat. Correspondingly the blower
speeds are approximately 1050 and 800 R.P.M. The Fan
Delay is effective only on the “OFF” cycle, as the fan comes
on at the same time the heat comes on, during the “Heat &
Fan” cycle.
-T: This option incorporates a two position toggle switch as
in option-3 above and functions the same way. In addition
a low voltage control relay complete with an integral
transformer is provided for connection to a remote 24 volt
thermostat. The fan delay works the same as in “-3” above
also.
-R: This option also
uses the two position
toggle switch as in
the above options.
Provision is provided
for a line voltage
thermostat. The fan
delay works the same
as in “-3” above.
