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 louver (which determines the vertical
air flow direction) is fixed and cannot be adjusted.
CAUTION
Do not adjust the air flow
louvers while warm air is
flowing.

Sensible Temperature Control

The sensible temperature control feature allows
comfortable heating which matches the conditions in
the room.
Based on the information collected by the room
temperature thermistor when the heating starts, the
heating capacity is automatically adjusted to achieve
a comfortable heating effect and to reach the
temperature setting quickly.

Adding Water to the Humidifier

Warm air is humidified when it passes over the water
in the tray.
To fill the tray, remove the bottom trim panel below
the louvers by pulling on both sides. Pull the tray out
and fill with water. Push the tray back in and attach
the bottom trim 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.
CAUTION
Do not remove the bottom
trim panel or the humidifier
tray while warm air is
flowing.
