The water level must be between the minimum and maximum water level lines, and the tethered controller must be correctly plugged in (red light on tethered controller will illuminate when cassette is powered on). When turning the unit on, ensure that both the power switch has been turned to the ON ( I ) position and that the standby button has been pressed.

1.7

| __

__

Water is appearing around the unit

| __

__

During normal operation it is expected to see some condensation of water on the media tray.

| If condensation is present ensure that mist outlets are unobstructed
Certain ambient conditions will cause condensation on the unit and in most cases will only occur on initial start up of the unit
If there is excessive water, refer to section 4.1
| PROBLEM| CAUSE| SOLUTION
---|---|---|---
2 .0| Blinking (error codes)
After the unit has shut down due to an error, a power cycle of the unit will be required by turning the unit off with the power switch for 10 seconds then turning back on. If the LEDs are off, press the standby button to turn on the flame effect.
__

2.1

| __

Unit continuously blinks one time

| __

Water level in the sump is too high

| Remove enough water from reservoir so that level is below maximum level.
If the problem persists, see section 4.5
__

2.2

| __

Unit continuously blinks twice

| __

Water level in the sump is too low

| Refill the water reservoir so that level is above the minimum level
If the problem persists, see section 3.7 if using bottles or section 4.3 if using direct water line
2.3| Unit continuously blinks

three times

| Defective level sensor assembly| Replace level sensor assembly
__

2.4

If problem persists, clean water filter and inspect plumbing to make sure pressure is adequate and nothing is obstructing water flow.
3 .0| Flame
__

__

3.1

| __

The flame effect has too much smoke or is coming out too fast

| Normal operation| The flame may appear overly cloudy at startup. Allow 10 minutes for flame to stabilize
Flame effect control is set too high| Adjust the flame height on both the secondary and/or primary controls
Filter is missing off of fan housing| Insert fan filter
__

__

3.2

| __

__

Mist is not coming out evenly

| The top cover is positioned incorrectly| Ensure the tabs on each side are snapped into place
Mineral buildup on the mist outlet| Perform maintenance cleaning
__

Unit is not level

| Adjust the feet under the unit to ensure that the unit has been installed level, front to back and side to side
Media is blocking air flow| Rearrange media to ensure mist outlet is not being blocked
__

The transducer is not operating correctly

– put the unit in test mode to test the transducer

| If the transducer is running, ensure that the emitter is clean and free of calcium deposits or scaling
If the transducer is not running, replace the transducer with the provided additional transducer
If using demineralized water, unit will not produce a consistent mist| Add 1/8 tsp of table salt to water reservoir to introduce electrolytes, only repeat when mist is not being produced correctly
Water in unit is too cold| Allow water to warm to room temperature.
__

__

3.3

| __

__

The flame effect is too low

__

Insufficient air intake

| Enlarge area for air to enter unit in such a way that it will reach the bottom. Refer to to installation guide for requirements.
Transducer is defective| Replace transducer
Cord is located over emitter on transducer| Relocate cord so that mist is free to rise off of transducer
Transducer is installed incorrectly| Ensure that the transducer is seated correctly
Flame is not rising| Refer to section 3.2 to 3.5
__

__

3.4

| __

__

Flame appears to be rolling back into the unit

| __

Insufficient air intake

Test Mode
Test Mode has been integrated into this product to improve end-of-line testing during production and can be used to isolate components for individual function testing. Test mode should be conducted by trained personnel only. The icons on the On Board Control buttons (Figure 1) do not match the commands they are associated with, when in test mode.

Ensure unit is connected to power and water is supplied.
Remove logs or top plate and set aside.
Press power switch on (Figure 1A). Presence of power will be indicated by one beep
Press the troubleshooting button (Figure 1D) on the side that the testing is required, unit will beep.
Press the following buttons to test functionality of listed components – press once will turn On and press again to turn off
After 15 seconds of inactivity the unit will beep and then return to regular Standby mode, or the On/Off button can be switched to Off to end the test mode.
