INFORMATION
Installation Instructions
Part One
PLACEMENT: UL approved for vertical installation only.
CONTROL OF HEATER: ON-OFF control built into product.
IMPORTANT!
It is extremely
important you
verify the
electrical supply
wires are the
same voltage as
the heater (i.e. 120
volt heater to 120
volt power supply
and 240 volt heater
to 240 volt power
supply). If
replacing an
existing heater,
check the labels
of the old heater
and replace using
the same voltage.
Hooking a 240 volt
heater to a 120 volt
power supply will
drastically reduce
the heater's
output. Hooking a
120 volt heater to a
240 volt power
supply will
destroy the heater.
Connecting your
heater to an
incompatible
power supply will
void the warranty.

an existing wall?
STEP 1 Mount The Wall Can
STEP 1 Cut Hole In Wall
The wall can is designed to fit between two standard 16" on-center studs. UL requires a minimum
clearance of 6" adjacent vertical surfaces such
as walls, shelving, drapes, etc. Manufacturer recommends 12" from finished floor and adjacent
surfaces. (Note: Front edge of wall can must be
flush with finished wall. If installing on unfinished
wall; face of wall can must extend from face of
stud to allow for thickness of sheetrock.) Secure
the wall can to the studs with two screws or
nails, right or left hand mounting (See Figure 1).
Cut a hole 10 1/4" wide by 16 3/4" high next to wall
stud. UL requires a minimum clearance of 6" adjacent vertical surfaces, such as walls, shelving,
drapes, etc. Manufacturer recommends 12" from
finished floor and adjacent surfaces (See Figure 2).

STEP 1 Removing RB heater:
A. Turn off power to the heater being replaced. Turn the thermostat to the highest setting and wait approximately 30 seconds (120 seconds for some electronic thermostats). If the heater turns on, you have turned off
the wrong circuit breaker at the electrical panel board. If heater does not turn on, proceed to next step.
B. Remove knob (if applicable) and screws to remove grill.
C. Remove heatbox from wall can, using the front of the heater to pull it free of the wall can. Be careful to
not touch the heating element or any of the electrical terminals on the back of the heatbox or fan motor.
D. (At this point you can make certain that power is turned off to the heater by using either a voltmeter or
circuit tester. Test each terminal of the Secondary Over-Temperature control to ground. No voltage should
be present! If no voltage is present, continue with the next step. If voltage is present, the right breaker or
fuse for this heater has not been found. Locate correct breaker or fuse before continuing.) Separate the
connection of the supply wires and lead wires.
STEP 2 Install heater assembly:
Install spring clips on wall can edge, two at the top and two at the bottom (See Figure 3). Lay heater assembly on its front surface, position rocker switch to be installed at bottom of wall can (See Figure 4). Make the
connection of the supply wires to the lead wires from the rocker switch. Position the heater assembly to fit
adapter plate to the surface of the wall can (See Figure 3). Be sure all lead wires are inside the wall can
before securing heater assembly (Use the four #1 32 x 1⁄2" machine screws; two at top and two at bottom).
STEP 3 Install Grill Frame and Grill:
Remove protective film from grill before installing grill. Place grill frame outside top and bottom flanges of
the heater assembly. Place grill over frame and secure with the four finishing washers and four #10 x 11/2"
Phillips oval head sheet metal screws (See Figure 3). Start all four screws before tightening (Note: Over
tightening screws may damage grill).
WARNING
Turn the electrical
power off at the
electrical panel
board (circuit
breaker or fuse
box) and lock or
tag the panel board
door to prevent
someone from
turning on power
while you are
working on the
heater. Failure to
do so could result
in serious electrical shock, burns,
or possible death.
Operation & Maintenance
How to operate your heater
1. Once installation is complete and power has been restored, turn the heater
switch on. Important: The heater will remain on until it is manually turned off.
Maintenance
As needed, or every six months, minimum.
1.)
WARNING! Before removing grill, turn the electrical power off at the
electrical panel board (circuit breaker or fuse box). Lock or tag the panel
board door to prevent someone from accidentally turning the power on while
you are working on the heater. Failure to do so could result in serious electrical shock, burns, or possible death.
2.) Turn the heater switch to on. If the heater turns on, you have turned off the
wrong circuit breaker at the electrical panel board.
3.) If heater does not turn on, proceed with next step.
4.) Remove screws and take off grill.
5.) Wash grill with hot soapy water and dry immediately.
6.) While holding fan (to avoid damage or bending), use a hair dryer or vacuum on blow cycle to blow debris through the top element (Do not touch element).
7.) Vacuum fan area without touching the elements.
8.) Replace grill and secure with screws.
9.) Turn power back on at the electrical panel board.
About the Heater Temperature-Limiting Controls
The heater is protected by two temperature-limiting controls . The first is a
high temperature reset switch, designed to open the heater circuit when
excessive operating temperature is detected. The problem must be assessed
and the limit must be reset to resume operation.
Further protection is provided by a secondary over-temperature switch,
which will open the heater circuit in severe over-temperature conditions, or
in the event of component failure. If this occurs, the heater must be repaired
or replaced.
Resetting the Manual-Reset Limit Control
If the manual-reset limit control has opened the heater circuit due to excessive operating temperatures, the heater will not work until the limit reset button is pressed. After allowing the unit to cool for at least 10 minutes and
resolving the problem causing the limit to trip; use a narrow object such as a
ball-point pen to access the reset button through the center section of the
heater grill. Press FIRMLY and be sure to listen and feel for a click, indicating
it has been reset.
Note that resetting the manual limit control may not restore heater operation
if a severe over-temperature condition has occurred. See the
Troubleshooting Chart below for more information.
