INSTALLATION
1. Screw off the front panel and disconnect the display and control unit
terminal.
1. Screw off the gas tube assembly (1) and take it out (2).
2. Change to the matched gas ejector tube assembly.
Note: It's necessary to examine the air tightness after change, to
check the seal ring on the gas control system installed well to prevent
gas leakage.
1. Connect display and control unit.
2. Flow rate selection: Within 10s, after the appliance is electrically fed
on but switched off (display blank), press Up and Down keys together
for 2s. After the buzzer rings once, "L" shows on the display, which
means that you have entered the flow rate selection mode. Press On/
Off key to enable the adjustment function, and then Up or Down key
to adjust the flow rate. Figure 5.17 shows the flow rate parameter
settings.
3. Gas type selection: After the gas flow rate is adjusted, press On/Off
key to both confirm the modification and enter the next selection
interface. The "q" that shows on the display means that you have
entered the gas type selection mode. Press On/Off key to enable the
selection function, and then Up or Down key to select a gas type.
The originally selected type is displayed the first time you press Up
or Down key, which is 12 (G20) by default. Figure 5.18 shows the gas
type parameter settings.
4. Model selection: After gas type is selected, press On/Off key to both
confirm the selection and enter the next selection interface. The "F"
that blinks on the display means that you have entered the model se-
lection mode (It's the factory default and no need to select, just press
on on-off key to skip this step.). Figure 5.19 shows the settings of the
model parameter.
