Humidifier and Air Flow Direction
Adjusting Air Flow Direction
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.
CAUTION Do not adjust the air flow
louvers while warm air is
flowing.
Adding Water to the Humidifier
CAUTION Do not remove the bottom
trim panel or the humidifier
tray while warm air is
flowing. Wait 5 minutes after
turning the unit off.
Set back
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.
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.)
