Set back

This function allows a minimum room temperature to be pre-set, between 38ºF and 78ºF (in 2ºF increments). This temperature should be set below the room temperature setting. The default setting is 60ºF. Once the Set back function is selected the appliance will start heating whenever the room temperature falls below the selected temperature, regardless of timer or manual settings.

Follow these steps to set and operate the Set back feature:

1.Make sure the heater is turned OFF.

2.Press the “Set back” button. The light above the button will come on.

3.Press the up and down buttons to set the minimum temperature.

When the “Set back” indicator is on, frost protection is operating, and will always prevent the room temperature from falling below the pre-set minimum temperature (as long as electric power and gas is supplied).

To turn this feature off, press the “Set back” button.

The unit will retain its ON or OFF setting after a power failure. (Default setting at the factory is on.)

Humidifier and Air Flow Direction

Adding Water to the Humidifier

Do not remove the bottom trim panel or the humidifier tray while warm air is flowing. Wait 5 minutes after turning the unit off.

Warm air is humidified when it passes over the water in the tray.

To fill the tray, remove the bottom panel by pushing on both sides and pulling it toward you. Pull the tray out and fill with water. Do not exceed the fill line. Push the tray back in and attach the bottom panel. Do not operate the appliance unless the humidifier tray is installed.

During operation a small amount of condensation is produced in the flue system and drains into the humidifier tray.

Adjusting Air Flow Direction

Do not adjust the air flow louvers while warm air is flowing.

The vertical louvers may be adjusted to move the air flow more to the right or to the left.

Use a screw driver or similar object to bend each louver to the desired position.

Do not bend repeatedly (no more than 5 times) or else the louver will break.

The horizontal louvers (which determines the vertical air flow direction) are fixed and cannot be adjusted.
