The wood grain fireplace has 2 working modes, Standby and Power on.
Standby Mode:
Connect the fireplace plug to power supply, fireplace powered on, the display board in standby mode, power supply light in red, all other lights off. Only ON/OFF button can work, other buttons do not work.

If it is a new fireplace, after powered on for the first time (ON/OFF in standby mode), long press MODE button for 3 seconds, feed motor light on, continuously feeding for 4 minutes and 50 seconds then enter into power on mode. During the feeding period, convention blower, exhaust fan and poker do not work. Long press MODE button will work as feeding only and do not have any other function.

After power on the fireplace, before press ON/OFF button, if detect the temperature control switch has been closed(for example, it is a hot fireplace when power on), exhaust fan and convention blower work on 220V voltage for heat radiation, the convention blower and exhaust fan will stop working when the temperature control switch off. If press ON/OFF button, fireplace enter into ignite program.

Power on mode: Include ignite, normal work, power off, 3 procedures.

Ignite procedure:
When the control board is connected with power supply, press ON/OFF button to power on the fireplace, the light will change from red to yellow green. MANUAL light, feed light on, exhaust fan and feed motor start working, exhaust fan and feed motor light on. The screen display room temperature. When the exhaust fan start working, fireplace inside will become negative pressure, when test the pressure switch is closed, the poker will be ignited, poker light on. It takes 4 to 10 minutes from poker ignited to fire flame. When there is fire flame, the temperature will increase, and when the fireplace inner temperature up to 65°C, the temperature control switch close, convention icon light on, convention blower start working, blow the heat into the room. Timing from the fireplace powered on to 12 minutes, if convention blower already works, it means ignite succeed, shut off the poker, ignite light off, then enter into normal work procedure. If 12 minutes later, temperature switch do not close, convention blower do not work, then the ignite failure alarm.

Press ON/OFF, feed motor continuously feeding for 3 minutes and 30 seconds, stop feeding for 1minutes, then follow FEEDING 3S/STOP 4S to feed spasmodically until ignite procedure finish. After ignite, feed under the related rank accordingly. The display board feeding light will uniform with feed motor, feed motor work and light on, feed motor do not work then light off.

Press ON/OFF, when time up to 5 minutes 30 seconds, exhaust fan voltage is 175V, after 5 minutes 30 seconds then the voltage rise to 220V until ignite procedure finish. After finish igniting, exhaust fan will work base on the related voltage accordingly.

During ignite procedure, press UP/DOWN button, rank light can switch circularly, but the light will onto the working rank only when ignite finish. During ignite procedure, press MODE will not work.

Press ON/FF and 12 minutes later, if temperature switch close, convention blower works (175V), this means ignite succeed, and shut off poker, ignite procedure finish, enter into normal work procedure. According to different ranks, each rank will have different feed times, exhaust fan and convention blower voltage. Press UP/DOWN button can switch the rank, rank 1 to rank 5 can switch in turns.

Auto-work mode:
The default work mode is manual mode, and upper descriptions for manual work mode, can switch to auto-work mode only when the ignite procedure succeed.

Press MODE button can switch manual mode and auto mode in turns. The MANUAL and T-STAT lights over MODE button will show work mode. Under auto-work mode, then can set temperature, when press UP or DOWN button, screen will show the saved value in EEROM, UP increase 1, DOWN reduce 1, 4 seconds later will recover display the room temperature. When room temperature 3°F lower than set temperature, fireplace will return to original manual set rank. When room temperature the same as set temperature, fireplace will work under the value in rank 1. Can not manual switch the rank under auto-work mode, if want switch the rank, then must switch to manual mode.

Power off procedure:
Press ON/OFF button enter into power off mode during the fireplace working procedure. During power off procedure, feed motor stop work, exhaust fan and convention blower work under full voltage, the fire flame will burn out slowly, temperature will reduce slowly, when temperature reduce and temperature switch disconnect, exhaust fan and convention blower stop working, power off finish, fireplace turn to standby mode. Timing from power off, if temperature switch not disconnect 30 minutes later, then shut off forcibly. During power off procedure, if press ON/OFF button, the fireplace will power on again, and enter into ignite procedure. (The ignite, feed motor, exhaust fan, convention blower icons will be show according to its related working mode)

Fault Alarm:
If have fault during ignite procedure and normal work procedure, the fireplace control board will alarm. Alarm with below situations.

Negative pressure alarm: Display E2
During ignite procedure, if pressure switch do not close, continuously detected for 30S and still not close, then stop igniting work and alarm. The reason for this situation may be resulted from the door is open.
During normal work, if negative pressure disappear, when control board detects negative pressure switch disconnect, delay 30S, if the switch still disconnect, then it will make negative pressure alarm. Exhaust fan and convention blower work under full voltage, feed motor and poker stop working. Temperature display will turn to E2 as indicator for negative pressure alarm. After stop feeding, temperature will reduce slowly, when temperature switch disconnect, the exhaust fan and convention blower will stop, the light still blink to remind user it makes negative pressure alarm, until user press ON/OFF button to reset and control board turn to standby mode again. Press ON/OFF button can not reset before the temperature reduce.
Reset: Plug out the power cable and plug in again, press ON/OFF button to power on again.

Over-heat alarm: Display E1
There is an over-heat switch inside the fireplace, the switch is closed if fireplace not over-heat. It will disconnect when the fireplace over-heat.

When the control board detects the over-heat switch disconnected, delay 30S and detect again, if still disconnect then make over-heat alarm. Convention blower and exhaust fan work under full voltage, feed motor and poker stop. E1 blink as indicator for over-heat alarm. When temperature reduces, exhaust fan and convention blower stop, press ON/OFF to reset. Press ON/OFF button can not reset before the temperature reduce.
Reset: Plug out the power cable and plug in again, press ON/OFF button to power on again.

Flameout alarm: Display E3
During normal work procedure, if detect temperature switch is disconnect, delay 30S and detect again, if still disconnect then make flameout alarm. Feed motor stop feeding, exhaust fan and convention blower stop working. E3 blink as indicator for flameout alarm. Press ON/OFF button to reset when it alarm.

Ignite fail alarm: Display E4
If temperature switch do not close after ignite for 12 minutes, convention blower do not work then make ignite fail alarm.

Timing from ignite start, if 12 minutes later, temperature still not increase to make the temperature switch close then make ignite fail alarm. Exhaust fan and convention blower work under full voltage, E4 blink as indicator for ignite fail alarm.
Reset: Press ON/OFF button to reset.
Temperature sensor fault alarm: Display E5
After connect with power supply, it will display room temperature automatically. Temperature sensor fault will display E5.

After open the feed door, feed light off and stop feeding. If feed door fault (open circuit) or door not well closed, then feed light off and stop feeding.

Remote control:
There are 4 buttons on the remote control, the function is the same as display board.

°C/°F switch temperature: Press UP and DOWN buttons for 3S at the same time, after hear “BEEP” sound, temperature display switch succeed.
