!
NOTE:
This heater is shipped with the outlets in
the front/front (D) configuration, see Figure 7. If another
configuration 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 upflow application. If unit is to
be installed as downflow, 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 floor 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 filter
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 first 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)

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 flat 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 flange
onto “L” shaped splice. Trim frame can be secured to wall
with screws (not provided), cement or adhesive.
