4. Installation of the Gas Pipe
a. Select specified rubber hoses or qualified rigid pipes
and gas pressure relief valve. (GB10546 and GB12244
compliant).
b. Select the dimensions of the pipe according to the
Connector Specifications in the Technical Performance
Parameter List.
c. The length of the rubber hoses cannot be greater than
2m when the liquefied gas is used.
d. Install a rubber seal ring between the gas intake of the
water heater and the hose connector. The rubber hose
must be connected to the red line of the hose
connector and must be fastened with a clamp.
e. Connect with a rigid pipe when the pipeline gas is used.
Install a gas valve, the passage of which has an
effective area greater than 45mm2, that is, the inner
diameter is more than Φ7.5mm.
f. After the installation, use the soapy water to check
whether there is a gas leak.
Using Methods
Preparations before Ignition
1. During the initial use of the water heater, open the
battery case and put in two D batteries according to the
correct battery polarity.
2. Switch the water inlet valve to the maximum and switch
on the hot water outlet valve to check whether there is
water flowing out.
3. Then, switch off the hot water outlet valve and fully
open the main gas valve.
Ignition/Operation
1. Ignition: After the preparation work, open the hot water
outlet valve, and the water heater will make a “poop”
sound, and then the hot water will immediately flow out.
If the water heater cannot be ignited for one time,
switch off the hot water outlet valve at once and restart
it after 10-20 seconds. (Note: For some models, adjust
the Hot/Cold Water switch to the hot water mode
before ignition.)
2. Outlet water temperature regulation: Switch the
firepower regulation knob to “Max” or switch the water
temperature regulation knob to “High”, the outlet water
temperature can be increased; switch the firepower
regulation knob to “Min” or switch the water
temperature regulation knob to “Low”, the outlet water
temperature can be decreased.
3. When the firepower regulation knob is switched to
“Min” and the water temperature regulation knob is
switched to “Low”, if the outlet temperature is still high,
then switch the season change knob to the
“Summer-Autumn” position. On the contrary, when the
firepower regulation knob is switched to “Max” and the
water temperature regulation knob is switched to
“High”, if the outlet temperature is still low, then switch
the season change knob to the “Winter-Spring”
position.

Hot/Cold Water Switch
Mode (for some models)
Open the hot water outlet valve and the
water heater will ignite automatically.
When the firepower is at “Max” mode,
the water temperature is at “High”
mode, and the season change knob is
switched to the “Winter-Spring” mode,
the outlet water temperature is the
highest.
When the firepower is at “Min” mode,
the water temperature is at “Low”
mode, and the season change knob is
switched to the “Summer-Autumn”
mode, the outlet water temperature is
the lowest.
