Operating the Heater
Turning the heater ON
When you press and release the ON/OFF button, the Temperature Level lamps will illuminate, the
combustion fan will begin to run, ON/OFF 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 the Temperature Level lamps will flash indicating a fault code. 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 | ON/OFF |
short time to prevent the internal |
|
components from overheating. |

The first time that the appliance is turned on, the preset temperature of 72° F will be shown on the display. Every time the temperature setting is changed, that temperature setting will be the latest data appearing on the display the next time the appliance is turned on.
To change the temperature setting, adjust the temperature control buttons until the desired setting is indicated.
When the desired temperature has been set, 10 seconds later, the display will show the current 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

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 | Economy | |
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.
When the heater is running at the LO setting, the Economy Mode does not function.
