Adding Water to the Humidifier
Do not fill the tray while the appliance is in operation. Close the door after filling. The humidifier tray and surrounding area are hot when the appliance is on.
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.

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 louver (which determines the vertical air flow direction) is fixed and cannot be adjusted.
