Operating Information

Turning the heater ON
When you press the ON/OFF button, the LED display
will illuminate, the spark will ignite the main burner and
the combustion fan will begin to run.
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 fault code 11
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

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.
