Technology Manual – Instantaneous Gas Water Heater 5L/6L CF USE INSTRUCTION Preparative Fix 2pcs A1 dry battery into the battery box. Open the gas valve and water inlet valve Turn on the battery power switch which is located at the bottom of the heater Ignition Open the hot water valve, the heater will ignite automatically, but the water pressure must be more than 0.025MPa. -
Page 18: General Safety Instruction
Technology Manual – Instantaneous Gas Water Heater 5L/6L CF GENERAL SAFETY INSTRUCTION Make sure of accordance of the gas to be applied with the requirement of nameplate Example: Gas type: NG (natural gas) 12T Gas Pressure: 2000Pa If the gas type of the heater needs to be exchanged, it must be conducted by certificated professionals Check whether the gas pipe leaks or not Please smear soap water on the connector, to check whether the gas pipe leaks or not. - Page 19 Technology Manual – Instantaneous Gas Water Heater 5L/6L CF If the air temperature falls below 0℃, unscrew the water plug near the inlet and let out the water in the heater, after that, screw down the plug. If the heater has not been used in a long time please let the water out of the heater too.
- Page 20 Technology Manual – Instantaneous Gas Water Heater 5L/6L CF General failure & Solution 1. If the water heater is only used occasionally, it may switch off suddenly. Cause: Too low voltage of battery supplying for ignition control(IC) and gas solenoid valve. Too low water pressure.
- Page 21 Technology Manual – Instantaneous Gas Water Heater 5L/6L CF If ignition can not spark properly, change IC. ※Technology knowledge: Min. working water pressure is 0.025 Mpa (0.25 kgf/cm microswitch and The correct connection situation for water driving axis is as shown in the following picture 2.
- Page 22 Technology Manual – Instantaneous Gas Water Heater 5L/6L CF 3> Check whether g solenoid valve can open or not when sparking; Listen the opening sound “Da” or touch to feel the opening vibration or measure the voltage at the gas valve with a multimeter. If this isn’t working, disconnect the solenoid valve from the base, remove any dirty on its surface and reassemble.
