Humidifier and Air Flow Direction
CAUTION
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 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.
CAUTION
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.
Do not remove the bottom trim panel or the humidifier tray while warm air is flowing.
Do not adjust the air flow louvers while warm air is flowing.
