the thermostat knob fully clockwise.
2. When the room reaches your comfort level,
turn the thermostat knob counterclockwise
until the heater turns off. The heat and the
fan will automatically cycle around this
preset temperature.

turn the thermostat knob fully clockwise.
2. When the room reaches your comfort level, turn
the thermostat knob counterclockwise until the
heater turns off. The heater will automatically
cycle around this preset temperature, however
the fan will run constantly.
3. To reduce the room temperature, turn the knob
counterclockwise. To increase the room
temperature, turn the knob clockwise.
Fan running continuously with no heat
1. Turn the fan switch to the "FAN" position.

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. It is important that you verify power has been
turned off and no power is going to the heater
before proceeding. Circuit breakers are often not
marked correctly and turning the wrong breaker
off could mean electricity is flowing to the heater,
even if the heater does not appear to be working.
If you are uncomfortable working with electrical
appliances, unable to follow these guidelines,
or do not have the necessary equipment, consult
a qualified electrician.
3. Once you verify the power has been turned off
correctly, proceed to the 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 element (Do not touch element).
7. Vacuum fan area without touching the elements.
8. Replace grill and secure with screws.
9. Turn thermostat to desired setting.
10.Turn power back on at the electrical panel board.
About the Heater Temperature-Limiting Controls
The heater is protected by a high temperature manual
reset limiting control, designed to open the heater
circuit when excessive operating temperatures are
detected. The problem must be assessed and the
limit must be reset to resume operation.
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, turn the electrical
power off at the electrical panel board (circuit
breaker or fuse box) and remove the grill. Once the
problem causing the limit to trip has been resolved
(typically heater is blocked or needs cleaning), push
button located on the left side of the heat box. Press
FIRMLY, and be sure to listen and feel for a click,
indicating it has been reset.
