HEATER CHECKOUT AND OPERATION
1.
After heater is completely assembled, rotate wall thermostat knob
counterclockwise until control stops. This is the minimum heat setting.
2.
Turn power supply to heater “ON” at main switch panel.
3.
Heater should not operate. If it operates, disconnect power and re-
check wiring.
4.
Rotate wall thermostat knob clockwise until it stops (maximum heat
setting) and wait at least 2 minutes. Fan control will delay fan coming
on until element is warm.
5.
If heater and fan do not come on, disconnect power and check wiring.
6.
Allow heater to continue to operate until room temperature reaches
desired comfort level. Then rotate wall thermostat knob counterclock-
wise slowly until thermostat clicks off. Fan must continue to operate
for a minute or so until element cools. If fan turns off immediately
when thermostat is turned off, disconnect power and check wiring.
(See Fan Delay Notice).
7.
It may be necessary to readjust thermostat a time or so until exact
comfort level is attained. Rotation in the clockwise direction will
increase the amount of time the heater will produce heat. Rotation in
the counterclockwise direction will reduce the amount of time the
heater is on.
NOTE: For best results, the heater should be left “ON” constantly during
the heating season as the thermostat, when properly set, will maintain the
desired temperature. In the full counter-clockwise position the heater will
remain off until the room temperature drops well below freezing.
MAINTENANCE AND CLEANING
Your heater is designed for years of trouble-free operation and requires
no special maintenance other than occasional cleaning. The motor is
permanently lubricated.
Once each year, the heater should be cleaned to remove dust and other
foreign material which has collected during the heating season, as
follows:
1.
Turn power off at main switch.
2.
Remove front cover by depressing plastic tabs with a flat bladed
screwdriver as shown in Figure 4. Release both tabs on one side then
rotate cover off of heater fan assembly.
3.
Use vacuum cleaner with brush attachment to remove dust and dirt
that has accumulated in heater (especially around element and fan
blade). Do not use water or any cleaners to clean heater
components.
4.
Replace grille.
5.
Wipe grille clean with a damp cloth. DO NOT use waxes or any clean-
ers that leave a residue since these may discolor during heater oper-
ation.
6.
Turn the main line switch on at the switch panel to restore power to
heater. The heater is now ready for another season of operation.
OPERATIONAL NOTICE
Your heater is equipped with an automatic reset over-temperature limit con-
trol that will automatically turn the heater off to prevent a fire if the heater
overheats.

TO REDUCE RISK OF FIRE OR PERMANENT DAMAGE TO HEATER,
THERMOSTAT MUST NOT CUT POWER TO FAN. THERMOSTAT
MUST BE WIRED AS SHOWN IN WIRING DIAGRAM SO THAT IT
CYCLES HEATING ELEMENTS ONLY.
CAUTION
!
NOTE: For 120 and 277 volt heaters connect the white neutral supply
lead to the heaters white pigtail lead, and connect the black supply lead
to the heaters black pigtail lead. For 208 and 240 volt heaters change the
color of the heaters white pigtail lead to black by wrapping with black elec-
trical tape. (Most electrical codes require the supply leads to be connec-
ed to black leads). Then connect the two black supply leads to the two
black receptacle leads. Connect the two red thermostat leads to thermo-
stat as shown in wiring diagram.
2.
Slide supply wiring under retaining straps in back box to hold in place.
3.
Insert wiring plug from heater/fan assembly into socket in back box.
4.
Fit heater/fan assembly into back box and secure in place with (2)
screws provided through the center slots in the fan assembly.
NOTE: Use the screws provided by the factory to install heater/fan
assembly to the back box.
5.
Turn disconnect switch mounted on heater/fan assembly “ON”.
