IMPORTANT INSTRUCTIONS

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.

1. Read all instructions before using this heater.

2. Read all information labels. Verify that the electrical supply
wires are the same voltage as the heater.

3. All electrical work and materials must comply with the
National Electric Code (NEC), the Occupational Safety and
Health Act (OSHA), and all state and local codes.

4. Connect the grounding pigtail (copper wire) provided in the
wall can to the supply ground wire.

5. If you need to install a new circuit or need additional wiring
information, consult a qualified electrician.

6. Protect electrical supply from kinks, sharp objects, oil,
grease, hot surfaces or chemicals.

SAVE THESE INSTRUCTIONS

7. WARNING
Overheating or fire may occur. DO NOT install the heater in a
floor, ceiling or behind doors.

8. WARNING
Fire or explosion may occur. DO NOT install heater in any
area where combustible vapors, gases, liquids, or excessive
lint or dust are present.

9. WARNING
Burn Hazard. This heater is hot when in use. To avoid
burns, do not let bare skin touch hot surfaces. Use extreme
caution when any heater is used by or near children or
invalids.

10. WARNING

Risk of Electrical Shock. Connect grounding lead to grounding
wire provided. Keep all foreign objects out of heater.

11. WARNING
Risk of Fire. Do not block heater. Heater must be kept clear of
all obstructions: a minimum of 3 feet in front, 6 inches
above and on both sides. Heaters must be kept clean of lint,
dirt and debris. (See Maintenance Instructions).

12. Use this heater only as described in this manual. Any

other use not recommended by the manufacturer may
cause fire, electrical shock, or injury to persons.

READ ALL

INSTRUCTIONS

AND SAFETY

INFORMATION

Installation Instructions

Part One

PLACEMENT: For best results install The Register Plus on an inside wall. Headers and bracing are not

necessary. NOTE: The wall can must be installed in the TOP UP (horizontal) position only. Heater is not
approved for ceiling mount.

THERMOSTAT: A thermostat is required. A Cadet Elec tronic Thermostat is recommended for ultimate control

and comfort.

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.

Warranty is void if

any material is

sprayed on the

element or blower.

How do I install for new construction?

STEP 1

The RM series REQUIRES A MINIMUM distance
of 6 inches from adjacent surfaces and 4½ inches
from the floor. However, Cadet RECOMMENDS
12 inches from all adjacent surfaces and 12 inches
from the floor (See Figure 5) for longer and cleaner
performance. Heaters must be spaced at least
3 feet apart.

Secure the wall can to the studs and/or sill plate
with screws through the larger (
(See Figures 1 and 2).

STEP 2

Route supply wire from circuit breaker to
thermo stat to wall can. Remove a knockout
and attach the supply wire with a strain relief
connector leaving 10 inches wire lead for later
use. Connect supply ground wire to grounding
pigtail in wall can (See Figure 4). Proceed to
PART TWO.

How do I install in an existing wall?

STEP 1

Cut a hole 12¾ inches wide by 6 inches high
next to wall stud. The RM series REQUIRES A
MINIMUM distance of 6 inches from adjacent
surfaces and 4½ inches from the floor. However,
Cadet RECOMMENDS 12 inches from all adjacent
surfaces and 12 inches from the floor (See
Figure 5) for longer and cleaner performance.
Heaters must be spaced at least 3 feet apart.

STEP 2

Route supply wire from circuit breaker to wall
thermo stat, then to wall can. Remove a knockout
and attach the supply wire with a strain relief
connector leaving 10 inches wire lead for later
use (See Figure 4). Connect sup ply ground wire
to ground ing pigtail in wall can.

STEP 3

IMPORTANT: Insert two drywall screws into
the small holes opposite the wall stud into the
drywall to rest against backside of sheetrock
(keeping wall can flush to wall).

STEP 2

Cadet’s Multi-Watt RM heater offers a variety of heat output options. You must first determine the
desired wattage and then configure the heating element wire connections. The heater is shipped from
the factory configured for 1600 Watts (240V) or 1200 Watts (208V) for RM162, and 1500 Watts (120V) for
RM151. If this is the wattage you desire, proceed to STEP 3.

On models RM151 and RM162, mark the wiring diagram on the back of the heater with the wattage used
for future reference.
