Turning the heater ON
Filter
ON
ON/OFF
When you press the ON/OFF button, the LED display
will illuminate, the combustion fan will begin to run,
and the spark will ignite the main burner.
This heater has an automatic ignition system. When
the main burner has lit, the combustion lamp will glow
red, and the spark will stop.
If ignition does not occur after 15 seconds, the
appliance will automatically turn off and a fault code
will be displayed on the control panel. This may
occur when using the appliance for the first time or if it
has not been used for a while. Try operating the
appliance again.
There may be a smell of burning dust or oil the first
time the heater is lit or when the heater has been out
of operation for a long time.
The appliance may make noises after ignition or when
it is turned off. This is normal and is due to the
thermal expansion or contraction of its components.
Turning the heater OFF
Press the ON/OFF button. Do not
turn off by unplugging at the power
outlet.
The fan will continue to run for a short time to prevent
the internal components from overheating.

Adjusting the Temperature
The temperature setting and the room temperature
are indicated by the L.E.D. display on the control
panel. When the appliance is turned on the
temperature setting will be displayed for 10 seconds.
The display will then show the room temperature.
The default temperature setting is 72° F.
To change the temperature setting press one of the
temperature control buttons once. The "Set Temp"
should light up and the display will show the current
temperature setting. Continue to press the control
buttons until the desired temperature setting is
reached. After 10 seconds the display will return to
showing the room temperature.
The thermostat automatically modulates the burner
and the fan to maintain the temperature setting.
The temperature settings available are:
• LO - burner is on minimum combustion
• 60° F - 80° F in two degree increments
• HI - burner is on maximum combustion
Economy Mode
ON/OFF
Pressing the Economy button will cause the
appliance to go into Economy Mode and the
green lamp will glow. This results in the
temperature setting being reduced by 2° F,
30 minutes after the room temperature has
reached the temperature setting. After
another 30 minutes the temperature setting
is reduced another 2° F. This could result in
the temperature setting being reduced by a
maximum of 4° F. The intent of this mode is to save
energy.
