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

CAUTION
To fill the tray, open the door as shown in the diagram
and pour water into the tray using the spout built into
the door. The air will be humidified as it passes over
the water in the tray.
During operation a small amount of condensation is
produced in the flue system and drains into the
humidifier tray.
If the water overflows from the water level hole, then
do not add any more water.
